Blurry and out of focus photograph around the edges.

[Alexalpha77]

Hi, I need help with finding the correct lens to use. I just bought my Alpha 7RV camera and a “FE 24–105 mm F4 G OSS Full-frame Lens” to go together with it! my subject matter are large flat paintings that I’m trying to document and my pictures are always blurry and out of focus around the sides of my photograph. The in focus part is in the center of my picture. But as you look at the photograph, the closer to the edges or sides, it gets blurry And out of focus. Am I using an incorrect lens or a portrait, lens or something? How do I get steady detail across the whole piece or the whole photo? Any help would be greatly appreciated.
Thanks Alex,

You could be using too wide an aperture.

You may need to experiment and find the best one to give more edge to edge sharpness.

A Google search will give you a lens review, this will tell you where to start the experiment.

That certainly would be helpful. So would a bit more info. That lens, from reviews I have seen is a very solid, if not spectacular, performer and should give good results for what you are doing. Having said that, for your use case, I probably would have chosen a different lens.

What is your setup? Are you shooting Raw or Jpeg? Are you hand holding or using a tripod? As above, what aperture are you using and at what focal length? If shooting in Raw, what software are you using?

By the way, welcome to the forum.

Here is an example of what I mean. Let me try posting the photo again. Apparently it didn’t work the first time or I don’t know what I’m doing on the form. I’m new here. Let me try again.
