Really great shots, thanks for sharing. Question about the lens, converter, hood combo. There seems to be some really bad light fall off in the corners of some of the shots, not sure if it's only at a one focal length or aperture, or if you have the wrong lens hood on or the converter is causing it? Maybe it's something with the PP you do/add? I see it on the crops as well, wouldn't expect it there.

I have that issue on a my DSLR with the 10-20 lens sometimes at the 10 end if I stack a filter and use the hood.

Am 99% sure he's applying the vignette as an effect--it's not from the optics.

On your 10-20 you're not going to get away with filter stacking without a step-out ring and oversized filters, as wide angles are susceptible to physical vignetting. Our 7-14s don't have filter threading for this reason.

OK, thank you. I don't know anything about the converters, didn't know what might be causing it.

Yea, I fixed the problem on my lens by going to two thinner filters, not something I use often, but reminded me of the problem I ran into with the corners.
