A final udpate as i think i found my issue
My 24-70mm is decentered.
Here two pictures, one with the DFA 24-70 @ 50mm and the other one with a SMC F 50mm
With the prime lens, it is pin sharp edge to edge. With the 24-70mm it's soft on the left hand side, sharp on the right.
Both shot on tripod, liveview, electronic shutter.

Yes with a F 50mm 1.7 it seems okay.
But this issue doesn't happen all the time, I've got sharp images handheld with my 24/70 later this week.
I'm just confused now.

Hi,
Here is another example, 1/160 f/8.0 iso100.
I'll try to extract 100% crop of the lefthand side

I managed to found one. Hope you can see that the bottom of the image is lacking of details compare to the top.

Here is the matter,
When i shoot handheld with my k-1, with shake reduction ON, images are often lacking of details on the left side no matter which lens i use.
Shooting on tripod with SR OFF, it's fine.
Do you think my camera is faulty. It fell once unfortunately, but i don't remember having this issue straight after the fall.
I'll try to be more specific with examples and exifs later.
Thanks for your feedback.

Hi,
I recently purchased a sigme 70-200 f/2.8 macro II, I checked the lensID. It's 8 16. So normally it will work fine.
The AF works, but when I turn on the camera, it takes a long time to work well. Let say 30s, it just works very very slowly, and then something happen and it works fine.
Do you think my copy got a problem?
Thanks guy
