I found a room, stuck a focal chart on the door and did the aperture sharpness test. Really cool to see the theory proven. f8 and f11 aren't too good.

I noticed my Mid shots at f2.8 and f4 were a bit blurry though, don't know why that could be.

Thoughts?

f1-f4

f4-f11

only showed WS of f11, cos you can see it so clearly.

These are JPEG files but they are the same res and are identical to the eye to the BMP's

Think my camera is up to scratch?

PS: I know my WB is completely out of whack - i should have reset it.

^ Results to be expected?

Hah, I am going to assume they are. Cheers everyone for your help in this thread. :]

I'm now selling this Ex3 for an overseas opportunity, but I do need to know if these are acceptable back focus images before I sell it. I don't want to sell someone something that needs a service.
