These three were taken with the NEX-6 and Pentax lenses.
First, with the Pentax-M 200/4. I've found this lens to be not too hot wide open, but this was (I think) at f/8 and it looks pretty good after a run through Lightroom. What do you think?
Next, from inside the (spectacular) aquarium, this was taken with (what else?) the 10-17 Fisheye at around f/8-f/11.
I like this lens on my K30, but for the NEX, I'm thinking of picking up the K 17/4 Fisheye because it's so much more compact. That, and the Lens Turbo should be an awesome combo. Anyone doing this already?
Finally, what's turning out to be my favorite lens so far, the Pentax-M 100/2.8. Super-tiny, and super sharp even at f/2.8! This is stopped down a bit, though. Also, this was taken through glass. I'll have to search for one that wasn't taken through a barrier later on.
Cheers!!
