[@harryniedecken5321]

Thank you. Great video and very informative as usual. I wonder why Panasonic and Olympus don't make a lens like this with the zoom controllable from a camera body dial similar to the manual focus. ( sorry meant aperture dial ) It would be big but still smaller than the motorized video rigs.

[@ricardorgomez]

I rented this lens last week to use for a portrait shoot as well as some general photography. The lens performed amazingly well with top notch image quality. Too bulky for street photography IMO. But that's not what it's for. I'll definitely be purchasing it for event and environmental portrait photography. Keep up the great work!

Don’t forget, for anyone reading the comments, that using Ex. Teleconverter option in the menu system makes this lens even more flexible. For example on my GH5S, shooting 1080p, I can get an extra 2.7x zoom reach. So essential this lens is a 10-121 f/1.7 but with a DoF with the teleconverter more around 2.8. Cheers!

Thanks for this review, Matti. You confirm my feelings: superb lens, but heavy and expensive. I love to travel light... I'm selling my Olympus 7-14 2.8 for the same reasons. Especially after noticing I use it on its widest angle anyway. So instead I use a 7.5mm f2 prime lens.

I suggest you try Viltrox EF-M1 (no speed booster). It works excellent on my G9. Of course there's no focal reducer, but you can use EF and EFS lenses, and Canon offers the magnificent 10-18 for $250 (even cheaper second hand), and the Viltrox works efficiently even with third party lenses (Sigma, Tamron, Youngnuo).

I'm considering this lens in combination with the (second hand) GH5, G9 or EM1-3, and I wonder about the focus behaviour in stills AND video mode, which lens and camera combination gives the least 'focus wobble' or 'pulsing' ? - I've not found this information yet, but I do know that the GH5 with the older firmware had a hard time focussing this lens in video.

the metabones is in a different class in my opinion, I tested against amazon 'commlite' which is similar to viltrox, and it was wayyy different. the metabones adapter is optically perfect and even uses the center of the sigma so it's sharper, but no waterproofing + bad focus is the downside

[@borispradel1037]

Hi Matti. I bought a G9 around a month ago after watching your reviews. I'm a Canon shooter so I have plenty of good Canon and Sigma glass. As I didn't have Lumix lenses I bought a Viltrox adaptor (versión 1, no glass only electronic connections (not speedbooster) so it's fully compatible with EFS and EF lenses. Just wanted to share that the adaptor provides near native glass speed and accuracy. I'm currently using a Canon 10-18 for wide angles (20-36mm on m43) (it's a great and cheap lens on Canon bodies and works amazingly well on the G9) as you don't really need wide apertures for landscape, and the Sigma 17-50 F2.8 OS gives me excelente results as a walk around option. The point is that Panasonic is following the path as the other companies in the mirrorless field, in which size of lenses is getting larger, very similar to DSLR, so using bigger lenses and adaptors on larger bodies as G9 works perfectly OK.

[@mattisulanto]

Adapted lenses make sense for somebody like you who uses two systems.

[@youknowwho9247]

Why would you downgrade to MFT from APS-C? Staying with the native Canon system would give you better results, likely at a cheaper price.

[@Princeton_James]

@@youknowwho9247 may be cheaper but not a downgrade at all. Especially comparing a G9 to any Canon APS-C camera. I did the same thing. Still trying to sell my Canon glass, but its the best move I've made. I have other APS-C mirrorless. Pretty much any modern mirrorless will smoke a Canon APS-C.

[@youknowwho9247]

@@Princeton_James Generally speaking, going down in sensor size is a downgrade. If one invest the same amount of money into aps-c or mft, the aps-c solution will always provide noticeably better image quality. In case of the G9 - it costs about as much as an X-T3, a6400 or M6 II. All three of those options are much better cameras than the G9.

[@professionalpotato4764]

@@youknowwho9247 I'm using a Caon APS-C (200D) too and I'm thinking of changing to M43. I shoot both videos and photos, but Canon has no reliable 4K options apart from the R5 or R6. The EOS M has a 2.56 crop, EOS R has a 1.6 crop I think. With no autofocus. So at that point, I might as well buy M43 with the smaller lenses and much better weather sealing and autofocus. Nearly nothing in the APS-C lineup is weather sealed. Body maybe but it's extremely rare for Canon APS-C lenses to be weather sealed. Also, looking at noise comparisons between M43 and Sony APS-C, I think it's safe to say Panasonic M43 sensors are a bit better than low end Canon DSLR sensors. I was looking at the XT-4, probably the best APS-C right now, but their lenses are waaaay too expensive. They cost roughly the same as EF L glass. (I don't use anything slower than F2.8 on APS-C). Comparing a full kit of lenses for XT-4 and the R6, the XT-4 is about 70% of the full-frame cost. So I'm going to invest in 2 systems gradually. M43 for my travel/food/product shoots and full frame when I really need the low light or bokeh.

Excellent review. I like the side-bit about setting the lens to 'A' and using a camera knob to set the aperture. Not always an obvious work-around. I got to play with this lens briefly and ALMOST bought it right there on the spot it was that good. I have the 42.5 Nocticron and this lens felt like a wide-zoom version of it. Stunning image quality and weight! It actually dwarfs my Nocticron in size. And that's already a big lens. This is pretty much a dream lens for me. Being able to shoot indoors without a flash at better than 6400 ISO and reasonably fast shutter speed would be amazing. Being able to do video equally well and, this lens is a bargain.

Sure we can consider any zoom as an option, but the 12-60mm f/2.8-4 is pretty far already to be a real option, because it is so much slower and has a variable max aperture. Just my opinion, of course.

How significant is the 2mm difference at the wide end between the 10-25 and the 8-18? Trying to decide trade off between low light and wider. I have only budget for one at the moment and need to be using them equally indoors (video) as well as for landscapes (photos)

[@mattisulanto]

There is a distinctive difference between 8 and 10mm, but I can't say what it means for your photography. However I can say, that the 10-25 is really nice for video work and much better than the 8-18.

[@MarkUKInsects]

It depends on your own style. I have the Panasonic Leica 12-60, its very nice. However, I do often find I need to go a little wider than 12mm. I have just purchased, the Panasonic 8mm, it is good, and fills a gap. But sometimes doesn't have that sparkle you get from really high quality glass, I should have gone for the Olympus 8mm f/1.8. I have had a play with both the 10-25 and 8-18 in store, even there the 10-25 was amazing. For me, 1.7 would be great at the high end, less so on wide angle. I can't afford this less now. But will save up, and wait rather than compromise.

[@kungula]

for me personnaly I would prefer a 10-35 mm f 2.8 as 25 mm is too short for my kind of photography. Also f 1.7 is certainly nice, but it makes the lens a bit heavy, bulky and expensive for mft. But of course it all depends what other lenses you have. My only Leica/ Panasonic lens is the 8-18 f2.8 -f4, all the other lenses I own are from Olympus and Sigma.

Definitely a unique range and aperture size. But if one can accept 24mm equivalent instead of 20mm at the wide end, and a stop slower at the tele end. The lens in the LX100 II is cheaper, lighter, smaller, and it comes with a free camera body :-)

[@youknowwho9247]

@@protestagain That's correct in physical terms, but not in regard to the results the lens produces. An image taken at f/4 on full frame will look exactly like an image taken at f/2 on MFT, given identical field of view, shutter speed and resolution. Example Let's assume a hypothetical scene that calls for the following settings on MFT: 25mm, f/2, 1/60s, ISO 200. Assuming I had, in that same scene, a full frame that only opens up to f/4, I'd get the following settings on full frame: 50mm, f/4, 1/60s, ISO 800. Those two images would look identical in terms of field of view, motion blur, depth of field and noise. In other words the f/4 on full frame behaved exactly like the f/2 on MFT. Which was my original point. This Leica lens on MFT does exactly what a 20-50mm f/3.5 would do on full frame. It's got the optical performance of a kit lens with half the zoom range for four times the money.

You are wrong with light amount... it's 1.7 , not 3.5 3.5 on FF only in bokeh things, but aperture is 1.7 which is really good. Do you see many FF 20 mm/ 1.7 lenses? Canon EF 16-35мм f/2,8L costs even more than panasonic 10-25 /1.7 and have almost 2 times less light coming through it

[@youknowwho9247]

@@UnluckyNewbie You're simply wrong. Full frame sensors are four times the size of MFT sensors, meaning at any given aperture a full frame setup gathers two stops more total light than an MFT setup. While f/1.7 will meter the same regardless of sensor size, a full frame f/1.7 will indeed be two stops better in low light. Here's an example to illustrate: We're in the same scene with the same light and taking the same photo. On your MFT setup you're getting ideal settings of 25mm, f/1.7, 1/250s, ISO 200. If I shot, on full frame, at 50mm, f/1.7, 1/250s, ISO 200 I'd get two stops shallower depth of field and two stops less noise. Since I'm aiming to duplicate the result you got I need to stop down. At 50mm, f/3.5, 1/250s, ISO 800 I'll get the exact same field of view, depth of field and noise as you at f/1.7 on MFT. There you go. An f/1.7 lens on MFT produces the same results in terms of depth of field and low light performance as an f/3.5 lens on full frame. This is why I'm saying that MFT glass is way overpriced. Once you actually want decent low light and subject isolation capabilities, you need two stops faster lenses on MFT than full frame for the same results. That universally results in the MFT option being the same size and weight as full frame glass, but at a significantly higher price.

As you can see, this scientific test conclusively finds that the MFT camera produces about four times more noise at the same ISO than full frame: www.dxomark.com/Cameras/Compare/Side-by-side/Panasonic-Lumix-DC-GH5-versus-Sony-A7-III___1149_1236 There's also a side-by-side comparison tool on dpreview's page that further confirms these findings for everyone to check and see: www.dpreview.com/reviews/image-comparison/fullscreen?attr18=daylight&attr13_0=panasonic_dcg9&attr13_1=nikon_d850&attr13_2=sony_a7iii&attr13_3=nikon_d500&attr15_0=raw&attr15_1=raw&attr15_2=raw&attr15_3=raw&attr16_0=200&attr16_1=800&attr16_2=800&attr16_3=400&attr126_0=1&attr126_2=1&attr171_0=1&normalization=compare&widget=1&x=0.6634075496131776&y=0.8331858999334762 As you can see there, ISO 800 on the D850 and a7 III indeed shows the same noise as ISO 200 on the G9. The aps-c D500 is still one stop cleaner than the G9, showing the same level of noise at ISO 400. And, again, this isn't even worth debating. It's not controversial among photographers that full frame is two stops better in low light than MFT. Its pretty much general knowledge. You should educate yourself on these things before making nonsense statements.
