    I assume my D700 in DX mode will give the same result (same DOF) @ 135 as say a D50 would at (135 * 1.5= 202.5) - or would I get better bokeh with the D50?

    You'd also be using the sweet spot of the glass.

    Ive thought about this before. I feel like 135 on FX may be sharper because you can get closer to the subject. Since distance affects DOF, the fact that I can get closer with a 50 on FX than on a DX camera makes me think that that's the case. Could be wrong though

    Yeah, I don't notice any difference in bokeh when I change my D700 to DX mode, so I am guessing bokeh w a 135 on a crop body looks identical to that of a D700 even though it is technically a longer focal length.

    I sold my 50 1.4 and I'm selling my 85 1.8 tomorrow, both for about $80 more than I paid for them. gonna look into a 135/2 soon, since I can't realistically see myself dumping $3000 on a 300/2.8 or 200/2

    Standing in the same place and shooting the same thing...

    DOF will be shorter on the 200/2+FX than on a 135/2+DX.

    And dont try and use crop body math to make you feel like youre getting some super sweet deal by getting a 135/2 and thinking its anything like a 200/2. Its not.

    it wasn't a means of justification to buy the lens, more of an afterthought that seemed kinda cool :wiggle:
