So I finally made up my mind and picked up a sigma 30mm f/1.4...

So far I like it a lot, though the focus seems a little dodgy at about 10-15 feet, however, stopping down to about f/2 seems to clear up the problem. Turns out there is a bit of a learning curve when it comes to using such a large aperture lens.

Anyway, heres some pics.

 

Very cool Yeah depth of field really sucks when you get to f-stops that wide. I've read that f/8 will give you the most depth before you have to start worrying about diffraction problems degrading the quality.

I really like the one looking through the lens but the one furthest to the right is my favorite I think. Nice work!

 

You'll learn to deal with the thin DOF. a 30mm won't look as thin as a portrait lens (like an 85, 105 or 135), but it may be difficult to focus because it's a wide angle (you see a bigger area, so it's harder to tell what is in sharp focus). Manual focusing (especially with a split circle focusing screen) makes things easier sometimes
