Clematis

Not really a photo of clematis, although it is, but a test to see what the corner sharpness of the X-A10 lens is like. The camera was hand-held so the test isn't very reliable, but nonetheless I was quite surprised to see that there's not all that much visibly obvious (to me) deterioration in sharpness towards the corners. I'm going to repeat the test with a tripod to get a more accurate idea. The reason for testing is that I'm trying to learn more about how depth of field works, as in quite a few pictures so far things I thought would be in focus aren't. So I was trying to find out first of all what I should expect from a subject with relatively little depth. Occasionally these kind of things interest me to the point where I set up some sort of test. At least it helps the learning. The clematis is 'Frances Rivis', and will have beautiful blue flowers in due course.
