Streak of light on all photos

Hi all,

Has anybody come across this massive issue on any Alpha Cameras?

If I take a photo with the mechanical shutter the photos come with a massive streak of light across the frame, when a shot is taken a fairly fast shutter speeds of 1/500 and above.

If I use silent shutter and e-Front Curtain Shut then the problem disappears. Video mode is good too.

Very odd, anybody has any workaround for this problem, please?

 

Shooting uncompressed RAW files, I've tried JPG too, several lenses, camera options, etc. on a A7III.

 

Thanks

Looks slightly curved, what lenses are you using? Are they native lenses or are you using an adapter?

Did you check for any obstructions or debris on the mounting area? Is the lens/adapter fully locked in (audible click) when screwing it in?

Hi LiveShots and thanks for your reply.

I'm using the Sony FE 85mm f1.8  - Zeiss 55mm f1.8 - Sony 28mm f2.0 and tried other manual lenses too. All with the same issue.

If it was the mount contacts, I don't think it would make any difference when I change to silent mode, and on silent mode I don't get the issue.

I just find it very odd and frustrating!  Any other possible problems?

Thanks!

      ISO Bracketing

      By Richard A · Posted

      ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.

      ISO Bracketing

      Thanks for the information. Since my original post, I did some "experiments" at different iso settings. Best results were obtained at iso 320, and then increasing the exposure by four stops in Lightroom. The biggest difference compared to using a higher iso was that there was detail in dark foreground areas, while at high iso the dark areas were blocked. This is consistent with articles I've read about ISO invariance.
