Re: Hyogen's Cuteness Overload (Kitty Cats)...a recent convert from Canon & crop-sens
Honestly, I only got the 35 1.4 because it's known to be so sharp wide open. I don't like shooting wide open b/c you'll likely lose dynamic range also.. I could probably get away with shooting wide open at 1.8 for my other lenses, but I don't really care about having the most razor thin DOF as possible anymore

The only thing insanely thin DOF is good for is showing off the capability of the lens. I don't like the fake 3D look that it produces a lot of times. Better to nail focus / get both eyes in focus usually. Nikon's newest lenses are so good...my favorite is the 28 and I'll probably get the brand new 20mm 1.8 lens that just came out. I could do without my 50mm now as I rarely ever use it (back-up lens) and I can't really justify upgrading to the 85mm 1.8G lens for now. It'd be nice to have it for the weather sealing though..
I'm pretty sure most wedding photographers shoot at 2.8 and higher fstop..maybe 2.2 at times, even when they have the most expensive Nikon 1.4 glass.. I'm not opposed to super thin DOF for tight headshots though. I sometimes lust after Canon's 85 and 50 f1/2 lenses.
Oh yeah, I was gonna add to my last post that I haven't shot a wedding with the D750 yet and come to think of it, I'll probably appreciate it quite a bit more once I do. Still, I agree the D600 is an absolutely amazing camera and not far off from the D750.
Also, just sold my 105 2.8 macro so I gotta change my sig! I pretty much preferred the old 85 1.8 95% of the time. Also, I think it's way too long for wedding ring macro shots for my purposes.
