Good test, this is the video I've been looking for, thank you.

[@OmaGhomrawi]

hahha, My pleasure.

[@frankfeng2701]

You can take full advantage of the 4K 30P 1.2x crop on A7iii while using aps-c lenses. Lenses like Sigma 16 f/1.4 and 56 f/1.4 have pretty wide coverage.

[@scottwu]

So if I shot in 4k30p, using the Sigma 16mm or 56mm in full frame mode , there would be no vignette?

[@LocustAndWildHoney]

Man, you just helped me so much! Thank you for showing us that at 14mm on the 10-18 you can turn off super 35 and get a full frame 14mm! You just make full video on that, it would do so well. A lot of people would be super happy to hear about this hack. Thank you!!

[@OmaGhomrawi]

I appreciate your feedback mate. These comments push me making more videos .

[@OmaGhomrawi]

I will take your request into consideration. I currently don't own the 10-18mm. Shall make a video when visiting my brother back home. He has one

[@CarringtonAdkins]

Always wondered if I could use an APS-C lens on my A7R2 in crop mode. Your video gave the answer + bonus as to comparison to clear zoom and specific lenses that work best. Thank you. [Subscribed].

[@OmaGhomrawi]

My brother is doing videos and recently upgraded from a6500 to a73. I recommend adapting APCS lenses to a73. and feeling very satisfied. But make sure to use very good APCS Lenses

did you upgrade ?

[@inellly]

@@JJ-vp3bd I was close to getting an A7SIII But then they came out with the A7C, so currently thinking of going full frame with the A7C and a new full-frame lense for the same price as getting the A7SIII body.

Curious here too. On Apsc but hwv good crop glass. Is it worth changing or sticking to Apsc?

This is SUPER useful. Just gone over to a7ii from a6000 and really didn't want to part with my sigma 1.4, now I don't have to as crop mode still looks insane.

[@OmaGhomrawi]

Matt Horner, Thank you for reaching out. This option isn’t available in Canon and Nikon so fot. I liked very much when switched to Sony mirrorless cameras

[@OmaGhomrawi]

Matt Horner Bar in mind, if you’re using APSC f1.4 lens for example. The shallow depth of field looks like f2.1 (I mean the look of the background blur) F1.4 x 1.5 (the crop factor) = f2.1

[@ocahan27]

hi matt. i have the a6000 and the 30mm f1.4 was looking to change to the a7ii but keep my sigma lens. mainly for cost reasons. would you say the image quality is still sharp in crop mode. ? dont wanna change then have to fork out more money on new lens lol

[@Server16116]

Thank you so much for this video! I was thinking of getting an APSC camera and a couple lenses, just to have something lighter and more portable to carry around for travel - you convinced me!

[@OmaGhomrawi]

I love APSC for traveling.

[@dorythomas1816]

note if you shoot with the a73 in 30fps on a crop lense the camera will crop to 1.2 by itself without the need for you to use clear image zoom.

[@OmaGhomrawi]

Didn't think about it since I shoot 25fps instead of 30. Would be great though!

[@HenryvdVeer]

Thanks for the video. I manage to get between 16.5 and 17 MP with this lens on my Sony A7III when shooting in fullframe mode and managong the vignetting in post bij Scaling the image by a factor of about 1.2 .However, that way it more resembles a 20mm lens on fullframe which would be about 14mm on apsc. So this 2mm gain is quite cool aswell :)

I have a full line-up of apsc lenses, so I'm curious, what would happen to the video quality if I used the apsc lenses on the A7C? Would the 4k video be cropped like photo resolution does in apsc crop mode?

[@natalijajelicic2408]

Great video, man!

[@simeonkolev1231]

If you remove the rear baffle and front lens hood most primes (not sony ones) will cover pretty much a lot more. Like the Sigma small and cheap 19, 30 and 60mm lenses. From the Sony ones the 10-18 was the only APS-C lens that improves when you remove the rear baffle. It is a very simple and easy to do solution. There are even custom lens profiles to fix the distortion in post.

[@OmaGhomrawi]

I've seen people doing this on Sigma and Canon Lenses, but I don't really trust using non-Sony Lenses. You know no more fast autofocus.

It kinda seems like you can just crop the photo in post to get more megapixels out of it, rather than using the in camera crop mode. It looks liek the crop mode chops off way more than it should.

Im seriosuly shocked... I just tested the A6300 vs the A7III on the same 16mm lens in 4k video... and the A7 is much cleaner even if it is not supersampling

Thanks Oma. Switching to the A7iii from A6000. I am glad I can still use my Sigma 56 f1.4. Will it still be F1.4 on the Full Frame A7iii in crop mode? I gather the focal length will be 84mm. Am I right? I am surprised that the lenses perform better on the full frame as far as sharpness is concerned. How is the autofocus when mounted on full frame in crop mode?? Thanks a lot again. Just the video I needed to see.

The 56mm will look like 56mm on full frame. However it is now 84mm on your 6000 cam Autofocus should work normally

Hi I don't remember I said that. However, APSC lenses made for APSC cameras in the first place. They are smaller and cheaper. Moreover, they work on full frame cameras with a crop.

I am on the same issues, I have the 16mm + a6500 and just bought a7iii. So, I think I could use the 16mm with the a7iii on crop for video for better ISO quality than used on a6500, because the crapped a7iii on 4k video will acts as 10MP a6500"S" for better light due to using the whole area of crop-size sensor without skipping pixels. The Sony a6500 on 4k only use one half of the sensor-size because it is recording 6k which is 12MP before downscaled to 4k. While the a7iii on crop mode using the same given sensor size of a6500 but with 10MP sensor instead of 24MP for better light, just like using a6500S instead of a6500 or the same affect as 24mm f1.4 on a7iii. for videos ONLY the 16mm is better than 24mm as quality and size

Man I need more videos like this. I have the A7iii and would like to get a F1.4 lens without spending much money. I don't like Samyang, they are too big and I'm interested on getting a 30mm Sigma. Please help!

[@OmaGhomrawi]

Hey Carlos, seems I missed replying to you! Sigma 30mm f1.4 will be 45mm on full frame. While Sigma 16mm f1.8 will be 24mm f1.4 on full frame

Unfortunately, it seems that this will only work for either video and JPEG shooting, but the zoom functionality disappears (greyed out on the menu) when shooting in RAW. Is this the experience of others?

[@OmaGhomrawi]

eventually, clear image zoom is unavailable when shooting RAW

[@christofferroeen7222]

hey oma What is the difference of the 16mm with a 2x zoom and the 30mm. i know there is a little difference off 2mm or something but what about the abortion or such ?!

[@OmaGhomrawi]

2x zoom on 16mm is technically scaling the composition to 200% while 30mm has different field of view, the subject is more compressed and the background looks closer to the subject. Try to find 2 images on the internet at 16 and 30mm (or 24 and 50mm on full frame). Scale the 16mm 2 times and compare it to the 30mm

Perfect review, the 10-18mm is interesting at 16mm on a7 :))

Thank you watching mate

How is the focus ? I am thinking to buy some crop sensor lenses and use them on Sony a7iii but curious if the focus is any good in both video/photo mood as well as the quality of the image

[@OmaGhomrawi]

hey Kai, Never face a problem with focus. Technically it depends on each lens autofocus speed, some lenses autofocus is slow. The good news, I'm using Sigma 16 and 30mm f1.4 DC DN on my full frame and satisfied with the result. Sigma 16mm f1.4 at f4 is sharper than Zeiss Full frame 16-35mm f4 in videos and photos. To me I use crop lenses on my a73 only when doing videos. Don't prefer to shoot on 12 megapixels in stills. All the Best.

[@shaunZ96]

does f stop change when you put apsc lens on full frame?

[@OmaGhomrawi]

it doesn't change f1.4 remains f1.4 but the shallow depth of field (out of focus background) looks like this equation (lens aperture x crop factor) example: 1.4x 1.5 = roughly f2.8

[@shaunZ96]

@@OmaGhomrawi thanks! im asking because i have 35mm 1.8 apsc and a a6500. based on your reply, i should either keep both or sell both.

[@OmaGhomrawi]

studioshaunx i have the 35mm f1.8 for full frame. It’s a fantastic lens Indeed it’s better to use fullframe lenses on Full Frame camera especially in stills
