Hi,

Using the Super 35 video mode there is a 1.5x crop on the a7r3.

If I put on a 10-18 would it fully cover the video frame - that is not vignette?

thanks.

not fully throughout the zoom range.

At 10mm you have severe vignetting, gradually receding until completely gone at about 14mm. from 14-18mm it covers Full Frame.

Hi,

Thats what I’ve read people say about photos.

Are you sure that’s what it looks like when shooting XAVC Super 35 video?
 
did you see this test?


At the ends I think it will (almost) be no vignetting.
 
At Full Frame I can get almost to 12mm without heavy vignetting. If you are shooting Super-35 I would expect this lens to perform all the way to 10mm. I have this combo, and will check it out if I can later today.
 
I didn’t see that - thanks.

Based on the APC lines (if they are correct) it looks like this lens might give total sensor coverage on the a7r3 for 4K video.

Still hoping someone with an a7r3 and 10-18 has actually tried it, but this looks good. Having a small 10mm lens for a handheld gimbal work (along with the zoom versatility) would just be awesome.

Thanks!! If you could check I’d really appreciate it. I’ve got a long trip coming up and need to dial in a lightweight video solution.

OK - when I got to the office I popped the 10-18 on the A7R3 and put it in Super 35 4K mode. I took some quick videos of walls and surroundings. There is no physical vignetting cutoff at all. At 10mm you do seem some gradual fall off in the corners - not unlike what you would see with any wide angle lens. It looks pretty good actually - I have only used this lens for still when I needed to get wider FF than my 16-35- taking me to almost to 12mm full frame. I just wish all lenses on the A7r3 were this lightweight.

I also have a power zoom 18-105 that I use on my a6500 - the preferred videographers lens - I plan to try that on the A7r3 for video as well. But that's a bigger lens.

I might add that you might also consider a 28 F2 - also very lightweight - but much brighter.

The 28 is a versatile video lens on FF and APS-C!
 
Cool - thanks!

Ive got the 28 for low light, but the 10-18 will be great for versatility. Using them both on a Crane Plus gimbal for a few weeks in China.

Again - really appreciate the help!

I would definitely reach out in the Sony a6500 community to see what experiences they have with the 10-18 regarding focusing capability. As I havent used this for video I can't really say how it works in that mode.
