Most useful review, a million thanks Rob !

[@RobTrek]

Thanks. Glad this video helped.

[@liutony4872]

Thanks for the 25mm lens test. I have the lumix version, the barrel distortion is about 1.2%(dxo), the Olympus f1.8 lens barrel distortion is about 0.5%. Olympus really did work hard on this lens, it is quite noticeable in raw files.

[@RobTrek]

Thank you!

[@Leptospirosi]

Great video Rob. another thing people don't speak about regarding this Panasonic 25mm f1.7 is that it focus shifts heavily form F:2 to F:4 which is the sweet spot of these kind of lenses, and it also have a very noticeable focus breathing if you use it for videos, even on Panasonic bodies. Another issue that affects Panasonic lenses (most of them) is that their chromatic aberration control is terrible, and this because Panasonic corrects that issue in camera via software, but Olympus does not. I know that CA can be managed in post processing and get rid of, but when you have to software correct something shifting pixels, you are also loosing definition and sharpness which you then try to gain back via sharpening in software, which introduces even more artefacts. I owned the 15mm PanaLeica and is a cute sharp lens, but it had plenty of CA on my EM-5 MkII, so I changed it for a 17mm Olympus, which still is not a stellar performer in the CA field, but is more manageable. Olympus 25mm is quite sharp, may be a tiny hair less then the Panaleica 25mm and the Pana 25mm 1.7, but it's evenly sharp across the whole image field, it has no hidden ugly sides and, overall, is a very well balanced lens

[@RobTrek]

Thanks for sharing that info. I think the Olympus 25mm is excellent. I never use the panasonic 25mm since switching. Too bad about the 15mm, I really like that focal length. If I ever get a panasonic camera, I will definitely get that lens.

[@lfcmarkeb7124]

the CA on the 15mm pany would be taken care of on a pany body (software)

[@Leptospirosi]

@@lfcmarkeb7124 I think looking at a recent video in 2021 that Olympus might have improved it's compatibility with the 15mm as I didn't see as much CA as I remember in 2015 when I had that lens. the problem is that new lens take a long time to be adapted in firmware on the cameras of the other company, being in Panasonic or Olympus. You need a really well built lens, like the Sigma 30mm 1.4 to be right form the beginning because controlling CA or distortion require complex design in the lens, so for budget product company prefer to fix any issue in software and other brands won't get the same attention as the lens in house.

[@entropyelectrodynamics798]

Is the autofocus and chromatic aberration when using with an Olympus body an issue for things like street photography?

[@RobTrek]

I'm not having issues with the AF, but many have said at f4 there is some missed focusing. The chromatic aberration is not bad and easily fixed in post processing.

[@florianschfr]

Now with the G9 II as first serious MFT video AF camera. Does the quicker AF speed of the Zuiko help there as well?

[@RobTrek]

It will depend on the lens. I'm not sure about the 25mm focus motors, but in general, all cameras will benefit from faster motors.

[@xmeda]

Panasonic focuses slowly, but it feels smoother too. Nice review. I just bought the Panasonic 25/1.7 today as I saw nice deal. For stills and low light to complement Oly 45/1.8.

[@finnmortier4721]

is the focus also slow on the panasonic when you're selecting your focus manually, for example when filming some cinematic shots?

Great video. Right from the beginning I knew how slow my Panasonic worked by just watching the Olympus work. A few months ago, I did one video with the Panasonic and auto focus was painful. It was either hit the auto focus and pulsing shows up or manually focus, which I found isn't that great with focus by wire but it worked. I can't remember video i watched but it was a Panasonic ambassador. He said the same about Olympus lenses on Panasonic. Depth from Defocus will sometimes not work and it will only funtion basic contrast detection.

This was on an Olympus camera. I wonder if the focus speed would be similar on a Panasonic body, or if the Panasonic or Olympus lens would be faster at video focus on the Panasonic body?

[@RobTrek]

Unfortunately I don't have a Panasonic body to test that scenario.

[@artistjoh]

@@RobTrek Looking further into this, other people seem to be in agreement that the Olympus lens does focus faster on Panasonic bodies as well as on Olympus bodies. The same appears to be true as well, of the Olympus 17mm f1.8 vs Panasonic 20mm f1.7. Olympus appears to use a better in-lens focusing system, at least for these lenses. However, there also seems to be general agreement, that out of these 4 lenses, it is the 20/1.7 that is sharpest, but also slowest and noisiest when it comes to AF on both Olympus and Panasonic bodies.

[@RobTrek]

[@jaychapman6448]

I find that with single point auto-focus the Pana lens in normal room light takes a very long time to focus and sometimes doesn't get it at all. I've been considering going to the Oly just because of that but I've also heard that because the Oly and Pana cameras have different internal cutoff filters that you can get a blue/purple fringe using the Pana on and Oly body unless you also use an external filter. Anyone know if that is true?

[@RobTrek]

The cameras and/or lens have software in them to correct fringing to a degree. Sometimes Pana doesn't have the data to fix Oly lenses and visa-versa. Firmware updates sometimes fix this, but it's hard to cover every combination. Best solution is to fix in post processing, though not always perfect. Look for lenses and/or cameras that have updated firmware. If the camera has not been updated after a lens has been release, then the chances of problems when mixing brands goes up. As for physical filters, that is way beyond my knowledge base to answer. Hopefully a more competent person can chime in. Maybe check in at the mu43 forums.

[@gernwind9262]

I've recently had an encounter with strong purple fringing/flares when I was trying out old Canon glass on my EM10 in some night shots. Street lights, and the purple was impossible to ignore, unfortunately it was also impossible to get rid of in post (Rawtherapee for me). What's your experience with the purple from the Pana 1.7 wide open? Specifically with nightshots? (I'd expect the software to have an easier time with the usual fringes on trees in daylight)

I'll look at my shots or take some new ones to specifically look for this. Try and get back to you asap.

@@RobTrek Thank you Rob! Been reading through some threads - experiences are inconclusive. Some don't mind the CA too much, others sent their lenses back... (One even complained about bad aberrations in ooc jpgs with the lens on a Pana body.) I' m currently leaning towards the manual and ultra-cheap Meike 25mm. If I have to deal with purple anyway... Also worth considering: If I need to get a high density 2A UV filter to set my mind at ease, that would add another 30 Euros to the cost of the lens.

It is a very practical comparison with the 2 lenses which I really needed get my head around. I am currently using an olympus EPL9 and using 14-42mm F3.5-5.6 lens and looking to expand the lenses collection. I am going to Iceland and likely take a lot of scenic photos, especially Northern lights, fingers crossed. I am debating whether to get the Panasonic or Olympus 25mm F1.7/1.8 (for better aperture for the northern lights/?weather proof) or another longer focal length lenses (for variety/purpose) as I have read a post that say my original lens may be sufficient for the Northern lights? Would you be able to give me some advice, please? Thank you for your help.

[@RobTrek]

I've never photographed northern lights so can't advise. However, consider the 17mm f/1.8 over the 25mm. I find it more useful long term. Others prefer the 25mm over the 17mm, so you'll have to decide.

Obviously that usually takes less than a second but it is noticeable and none of my Olympus lens does this. Is is common for all Panasonic lenses OR is it a thing about lack of understanding between the Olympus body and Panasonic lens OR my lens is broken? Thank you very much for your time and effort.

Thanks. My ears are not quite as sensitive as they used to be so I can't reliably say if the 25mm would be any better. For video, you want to use an external mic.

I'm using all 12-35/f2.8, 12-60mm/f3.5-5.6, 20mm/f1.7 and 45mm/f1.8. First two as travel lens (image quality is pretty good on both, 12-35 suffers from lens flare and has shorter zoom range ... 12-60 was very cheap as G80 kit lens and it's surprisingly flawless). last two for indoor photos with people and 45mm for outdoor photos as well (people, kids, ...).

Have you used the Panasonic 25mm 1.4? I can't see why the price difference is justified. The 25mm 1.7 is $150 and the 25mm 1.4 is $600.

[@RobTrek]

I know how you feel. The differences are very subtle in the final image. Much of the cost is the Leica name and build quality. It's definitely not a lens that I need, but I'm sure others can justify the purchase.

[@manuelzertuche6416]

Please please do your video on the TG5

[@RobTrek]

Okay, will start working on it. Give me a week or two.

[@aodreds]

From Thailand, this is helpful review Thanks so much 👍👍👍

[@RobTrek]

Glad it was helpful!

[@chillimoroka7744]

Great comparison, still trying to decide between these two and the Sigma 30mm f1.4... I do stills on OMD EM1 mark 1 and Pen F but you never know when one might venture into video.

[@RobTrek]

Don't forget the Panasonic 20mm f1.7 pancake. I foound the 30mm a bit bulky. Definitely stay Olympus for video. Wait for a killer deal on the Oly 25. I've seen them $250. I bought mine used for $200.

[@Dallex_]

I dont know if its just me but when the Panasonic lens focuses it actually looks a lot better in video quality. Also maybe you could do a comparison between the 12-50 olympus and the 12-40 pro

[@RobTrek]

The Panasonic is a fine lens, looked kinda the same to me though. I don't have a 12-50mm to compare. Thanks.

[@bedoinuk]

Fair assessment, Panasonic seems to be more hesitant to change focus. For me personally it's not important as I haven't used AFC in video (or stills FTM) like ever. So I'll just carry on mixing and matching Olympus with Panasonic as needed... :-)

[@RobTrek]

Mix and match works fine for photography. Just watch for firmware updates on the lenses for compatibility issues.

[@myxsys]

Am surprised in photography C-AF performs the same in both lenses. However, I've noted Olympus lenses tend to be brighter and a bit desaturated than Panasonic lenses. I wonder why is that?

[@RobTrek]

It varies lens to lens. Ultimately the differences are very subtle and shouldn't persuade your buying decision.

[@KingTut14]

I bought an Olympus 25mm f/1.8 for my Panasonic G7 a few years back. and now I have problems as well. AF is great all around, and is faster than any of my Lumix lenses, but when it comes to shooting video with AF, here is what happens. my G7 starts to make this loud noise when tracking me. and it records this noise on all the videos where you clearly hear it. at first, I thought my G7 broke and I need to call support. but after doing tests, I noticed that this ONLY happens with this Olympus lens and while I am recording on any video quality BELOW 4k. After this, i realized it's best to buy lenses of the same brand. or you'll always run into weird probs the seller at the store will never tell you about..

[@RobTrek]

I think this is generally true, especially for video. Thanks for sharing your experience.

[@CMBDIA]

you brought up some good points. i have the panasonic 25mm f1.7 with my panasonic g85 and i just picked up a used olympus e-m5 II. I might have to consider picking up the equivalent olympus 25mm. if i feel like upgrading in the future, i could consider the leica 25mm f1.4 or the olympus 25mm f1.2 pro lens.

[@RobTrek]

Thanks. Those are all great lenses you mentioned. There are great reviews from my peers on all of those. Be sure to check them out as well.

[@steadicamwalker]

25 14 is not a good lens for video. Its AFc is too slow

[@anups7958]

Amazing video!

New to your channel and wanted to say that I found this review very useful - excellent video! Thank you!

[@RobTrek]

Welcome and thanks! Catch me in my live streams if you can.

[@patlangdon1015]

Great video to see, in general & for me specifically because I’m looking at a 25mm now & this zeros in my decision- showing the differences graphically like this is fantastic. And, I’m also looking at a used but mint TG5 too lol! I want & need it, as a tough camera & it’s an Olympus! Although some time has passed since this was posted it’s a nice fluke to come across it now. I’ve seen your vids on the TG5. That makes it good to go for me. Excellent feature set on these little beasts & I like the look of it. As usual, a great help, info & fyi content Rob. Also, this vid was so funny lol... bring Elly more often (do I have the dog’s name right?)

[@RobTrek]

Thanks. TG5 is fun little camera. I have a few vlogs I've done with it on my channel. Yes, Ellie is her name. I forgot she was in this video!

[@wahabdilawar]

Excellent video, for those who can't decide, which lens to buy, but have decided to buy a 25mm for MFT. I think that the Panasonic was unacceptably slow on the Olympus body, especially for vlogging and for subject tracking. I have also noticed some issues with the chromatic aberrations, which my em-10 gives with the Panasonic lens, which it never gives with any of the Olympus Ienses and its not easy to correct in post either. However...the slooow "acquisition" of face focus by the Panasonic looks kinda cool. Feels like someone is manually focusing it...lol. Very interesting video. Thanks a lot.

[@RobTrek]

Thanks. It's too slow for vlogging. For cinematic shots, maybe but I think slow focus should be more intentional or consistant. This lens sometimes locks right in and most times is very slow.

[@Dron011089]

Good comparison, thanks!)

[@RobTrek]

Thanks for watching!

[@gordon3988]

Appreciate the video…disappointing results! Was considering a OM camera; most folks say no issues if using my Pan lenses even in video (other than the IBIS), but this doesn’t support that.

[@RobTrek]

The Panasonic lenses work pretty well on the EM1 and OM1 series with phase detect. I don't think I done a video comparing on higher end models.

[@TheDodgefan9]

This was really helpful. I've just bought my first real camera, a used Olympus PEN. I ordered the 14mm & 25mm Panasonic lenses and the basic Olympus kit & 40-150mm zoom lens. I don't shoot video fortunately, so the focus on the Panasonic prime lenses should not an issue for myself at least, and they were relatively affordable.

[@RobTrek]

Congrats on your PenF! It's a great camera and even though I have several other newer cameras, it's still my "go to" camera for my personal photowalks.

[@ohwhoaitzjoe]

I've never noticed anything from aquiring focus for stills thankfully.

[@RobTrek]

Me neither. Some have said that at f/4.0 there is some back focusing. But I've never experienced it.

[@theovandenberg4682]

Hi Rob, maybe i missed it. Can you point out which AF field pattern you are using. Thanks for your videos, they are very intuitive.

[@RobTrek]

Thanks. I set the pattern in video for face detect so it uses the full frame. In the continuous shooting sequence, I used single point center and C-AF with Release Priority C Off.

[@Hoggdoc1946]

Maybe that's the reason it's half the price of the Olympus lens. Also remember Olympus classifies this lens as one of their Premium lens, don't think Panasonic does the same. I wonder how the DG Summilux 25mm f/1.4 lens would compare to the Olympus lens?

[@RobTrek]

Hard to say why Olympus charges as much as they do for their 25mm. I hear the Summilux is sharper and contrastier. I don't own it so can't compare.

[@HaraldEngels]

My Panasonic 25mm F1.7 works great on my Olympus E-PL6. I like the lens but I did not pixel peep the results since my usage scenario for this combo (street photography) is not critical.

[@RobTrek]

I use the lens all the time on my E-M5 Mark II. Works great!

[@foxfaisal82]

Can you also please make review videos for Sigma lenses for MFT if you don't mind? :-)

[@RobTrek]

Hi. Sorry, I don't own any Sigma lenses to test.

[@foxfaisal82]

Rob Trek. It’s OK. Thank you very much :-)

[@keithholland9401]

I have a Panasonic G7 and an Olympus PEN E-PL7 and the Panasonic 25mm f/1.7 and 45mm f/1.8 lenses which I used several for photographing dogs at or after dusk at the L.L.Bean Discovery Park in Freeport, Maine in December. Every year they have hundreds of Christmas trees lit up which make for some really cool bokeh. Since my G7 lacks IBIS, I mounted my Panasonic 25mm on my G7 and my Olympus 45mm on my PEN E and I got a lot more photos in focus with the Olympus system than the Panasonic. Obviously, this is a pretty challenging test for any camera since dogs don't usually hold still for long, but the Olympus camera and lens would almost always get at least one shot in focus after taking a few while the Panasonic camera and lens would miss focus so much that I eventually just gave up using it and stuck to the Olympus, even though I preferred the 25mm focal length for that type of application. As much as I love that little Olympus 25mm for shooting subjects that aren't moving too fast in good light, it leaves a lot to be desired for low light photography, even on a Panasonic body.

[@RobTrek]

Thanks for sharing. Appreciate you taking the time to write.

[@keithholland9401]

Glad to join the conversation! I love your videos! I've been watching them for months and I've found them to be very helpful and informative.

[@mikecolley1093]

I got the panasonic version for stills I find it ok not in to videos but I have heard great things about the Olympus versions maybe I try it out in my local store

[@RobTrek]

Bring your lens with you to compare. Try them at different apertures. Some say the Panasonic is even worse above f/2.8. I was using f/1.7 in this video.

[@howardtowler6146]

I did it the other way. Lumix g9 and then the Olympus 12mm f2 and the 17mm F1.8. And a kamlan 50mm f1.1.

[@RobTrek]

Nice!

[@nellatrab]

This test review is right on Rob....while I do not own the Oly 25mm I do have the Pan 25...I don't do video, and sometimes it even is slow to focus on my EM 10 Mll for stills. Thx Rob

[@RobTrek]

I've noticed that on rare occasions. Not enough that I don't want to save $100+. But for video, it's not worth the savings.

[@Stonecones]

Olympus f 1.8 25mm $299 new, Just got the Panasonic 25mm f 1.7 for $130 new. Only reason to pay double is the better AF in video in Olympus for video only.

[@RobTrek]

That's pretty much it. Some say the Pana back focuses at f/4, but I haven't noticed it.

[@GoA7250]

I have a Lumix 14mm that will only manually focus once after turning autofocus off on my E-P5

[@RobTrek]

I don't have that lens but maybe check for firmware updates that might fix it.

Nice video! That Pana lens is really slow, at least at Oly bodies. 🤔 Can't wait for the Oly rugged camera review. Cheers!

Thanks. They are slow in video. Actually a little weird in stills, but not enough to make a difference that I can measure.

[@niasboiii]

@@RobTrek hey Rob, do you know how the here slow Panasonic works on a Panasonic Lumix camera? Do you think that's a better connection? I am currently thinking of selling my Olympus lenses I currently use with a G70. A 17.5mm and 42. 5mm. Aim to get a 25 and 20. Later a 15/14 and 42.5

[@niasboiii]

@@RobTrek also do you here use the Panasonic 25mm I or II Version?

[@RobTrek]

@@niasboiii It's the 25mm f/1.7, I don't think they made a version II. There are two versions of the 25mm f/1.4 which this is not.

[@RobTrek]

@@niasboiii I didn't test on a Panasonic, but it should work better. I really don't know.

[@wazzazv614]

I think some of the Panasonic focus problems have been improved by recent firmware upgrades from Olympus specifically for these lenses Love your work Rob

[@RobTrek]

Thank you.

[@lenzielenski3276]

Here's an idea: stop depending on technology and DO IT YOURSELF. Auto focus will never replace manual focus for determining the focus intent of the photographer.

[@RobTrek]

Ok.

[@Group51]

Hmmm. But I love the Panny 14mm 2.5. And yet some of the focus hunting performance in this video is familiar. Food for thought.

[@RobTrek]

The 14mm is a great pancake lens. Quite a bit wider but definitely worth a look. Thanks.

[@Group51]

@@RobTrek yes, great for photos, nice and sharp, but I’m kicking my self now, realising that the 12mm Olympus is less than £100 more on eBay. And a bit disappointing that in the updated 14mm I got, where it promised quieter focusing in video...is still loud.

[@DaddyJamesFilms]

in this video you have the mark ii is the same with the mark iii

[@RobTrek]

The E-M5 Mark III will do better, The E-M10 Mark III will be the same.

[@DaddyJamesFilms]

@@RobTrek so do you think this camera is better than the g85?

[@steveworthington930]

Hi Rob, been looking at the Pany 12-32 MM len,s. Had great review,s, but was worried how it marrie,s up to my OMD. This nail,s it, work,s fine for still,s, not interested in video, so all good. Around £90, equiv Olympus is pro glass only, circa £500, no brainer. Until I can afford the 12-100 pro len,s, circa £750 the Pany fill,s the gap.

[@RobTrek]

I use the 12-32mm a lot on my E-M5 Mark III. Seems the panasonic lenses work well with the phase detect AF cameras from Olympus for both stills and video. I concur with the great reviews on the 12-32mm. It's sharper than my Oly 14-42mm and nearly as sharp as my Oly 12-40pro. I like the wider 12mm focal length and the compact size.
