Hey, ecoyd1, I wonder if you could give me a little advice?
I recently took the D300 out and did some more testing with it. I took a few seascape/landscape shots, to see what kind of DOF I could get with F14/F16 compared to F11 that i used to use with my old FZ50.
When I got home and looked at the files, I was less than impressed by the sharpness of the images. Now, my first thought was that it was the lens, and then that it may of been my technique, but after some research I found that DSLR sensors actually suffer from diffraction when used with lenses stopped down to higher F numbers. What was more surprising was that from research I've done, it looks like images produced by the D300's sensor start to be affected by this sensor diffraction at around F8, which isn't much DOF for landscape...
Now, I've done a little testing at home and it seems like I can push the aperture to F13 without too much loss of IQ compared to wider apertures, and with a little increase in contrast and a sprinkling of unsharp mask in post processing, I can artificially raise the perceived IQ to around that of F6.3 at the centre of the image and around that of F11 at the edges, but with the extra DOF of F13.
With all that in mind and knowing that you don't do a huge amount of landscape shooting, I wanted to ask what your take on the sensor diffraction of the D300 was and what kind of apertures you use for landscapes, or shots where you want to maximise DOF?
