Sony A7c Issue?

p.1 #1 · p.1 #1 · Sony A7c Issue?


Last year I was really happy with my A7c paired with a Tamron 20-40mm f2.8. My images were sharp, detail capture was amazing, dynamic range was fantastic. Overall, it was an amazing camera. I regret selling it and the Tamron 20-40mm f2.8 as well.

Three months or so later, I ended up buying a new A7c and a new Tamron 20-40mm f2.8. I applied the same, identical settings on my new body, but there is a very noticeable difference in IQ. My new A7c does not capture images even remotely close to my old A7c! I have tried 3 different lenses, but the results are pretty much the same. The images I'm getting now are equal or less than an APS-C camera in terms of IQ. Again, same settings as my old A7c, so there should be no difference.

Is there a possibility that Sony crippled its new A7c causing the images shot with the newer A7cII and A7cR to look remarkably better?

The A7c used to be my go-to camera for travel. Now I can't even capture individual strands of hair on a subject. It's like a camera movement blur I see in most images now.

Anyone else having this issue? Again, if you have an older production A7c, chances are you are getting great images. I'm more concerned about how has your new A7c been performing?

Maybe you just got a bum camera. It really wouldn't do Sony any good to purposely make a camera worse later in a manufacturing cycle. I can't see a scenario where someone at Sony would think that is a good idea.

Sorry to hear that. Have you tried setting the diopter adjustment on the viewfinder? You might be having trouble focusing if that isn't set correctly.

Maybe factory reset it and reenter menu choices?

You have a new body and a new lens? That makes me think of a lens problem, not the body. Have you tried the lens on another body and another lens on the new body that you can compare to known good results?

I tried 2 other lenses on this body, same results.

I thought it might have been a diopter adjustment issue, but I'm using AF tracking. Also,I tried using the rear lcd instead of the evf but got the same results. The images are in focus, priblem is the detail capture. Best way I can explain it is that it's like I'm shooting with an APS-C camera.

For any such problem, there is an obvious response: show some examples.

Specifically you are complaining of lack of sharpness.
So take some photos where there should be something sharp if focus is off.
ie a flag pole against a blue sky is not appropriate.
Use high shutter speed.
Turn IBIS off.

APS-C cameras have no issue capturing plenty of detail.
AF Tracking has a use.
Even for Bird in flight, I rarely use it.
It is in no way a guarantee of AF success.

What does that even mean? Makes no sense.

I'm not subscribed to the buy/sell here, so I can't post any pics (other than a link to my flickr).

The shots I'm taking are mainly of people indoors. The AF tracking locks on to their eyes, so that's not the issue.

If you compare two indoor images, one shot with a full frame camera, the other with an APS-C camera, you will notice the difference. I have shit with both formats, and I can attest to the fact that there is a major difference.

Not a chance.


PS
As others have suggested, some example images could help to track down the problem.

You can post pics here, as you said, using Flickr (or other hosting site).
Eye AF can be used without tracking.
If you are going to maintain that there is a major difference between APS-C and Full Frame, I doubt people will take you seriously.
Googling "full frame vs aps-c blind test" or similar is all it takes to convince anyone.

I'll take some pics this weekend and post tgem on Flickr with a link.

Please don't misunderstand me. I'm not knocking APS-C. I used APS-C successfully for several years before going full frame. APS-C has its place and its merits; however,low-light performance and
dynamic range are not strong points of APS-C compared to full frame. Yes, APS-C performs great outdoors for sports and wildlife, but there is a reason why wedding and portrait photographers use full frame. Also, again, not knocking APS-C, but if APS-C was the best format in the world for every type of photography (including low light performance), why are full frame cameras even on the market?

What I shoot most is interior photography. People inside dimly lit places. Dimly lit churches, castles, etc. The right tool for the job in my case is a full frame camera with fast, wide lenses.

I actually have shot interior, low light shots with APS-C cameras in the past, and I can say from experience that the results (for me) are way better with full frame than with APS-C.

That being said, my current A7c does not capture details as well as my old A7c.

Post some samples from your old a7c, too.

Were you using the same iso setting? You may also want to test different AF modes. AF-C doesn't hit perfectly all the time, especially under low light condition.

There may very well be a problem with the lens mount that is not in perfect alignment. I would send the camera and a lens to Sony along with sample pictures that show the problem.

Did you change your monitor/computer/software settings since you owned the first camera?

What was your shutter speed on the images? You may have low detail because of movement (you, your subject, or both).
