Soft, borderline contrast.

Prescreen for this image too please, and what's the meaning of borderline contrast? And where is the borderline in the image located? Thanks.

Dirty, borderline soft/color/contrast.

Borderline = may or may not be an issue.

I meant like how can we spot if there's a borderline contrast issue?

Recognize that if there is not clear/unfiltered light on the aircraft that chances of acceptance here decrease.

Hello,

I have been using my Sony A7RIV camera for around 6 months now with the 200-600mm lens, and since the start of late May 2023, I start to notice a vignetting created when using F8.0. When I first bought the lens and camera there isn't any vignetting appearing. I tried now F13 and it also has vignetting while it doesn't before. Is there something wrong with my lens? And can APS-C 35mm mode turned on reduce vignetting? Thanks.

Not really going to try to diagnose a lens issue remotely, especially since I'm not a technician. Maybe there is a Sony lens technician in the forum who can reply.

Yes, cropping the sensor to APS-C should eliminate any vignetting issues.

Thanks! By any chance, do you know any Sony technician in this forum?

[Stanley JH]

And I tried to recover the images that I have vignetting last time, is the vignetting still appearing here?

I do not.

Yes, and also badly overprocessed.
