Really? This one, http://www.bhphotovideo.com/c/product/898836-REG/Sigma_340306_35mm_f_1_4_DG_HSM.html or an older one? I've heard nothing but good things about it. What was so bad about it for you? I have the 10.5mm, but thanks, Nice lens for sure.
I'm debating between picking one of these up for my d300 within the next few months. I just started looking into the 18-35mm tonight. From what I can tell there doesn't appear to be much of a significant difference in quality and sharpness. The versatility of the zoom would be nice but ultimately I want to go with the faster lens here. I'm really torn between the two right now. Is the 35 1.4 AF much better? I would assume the 1.4 is also better in low light and I know could still use it should I ever decide to get a full frame camera (though I'm 99% sure that won't happen) I enjoy shooting portraits too even though I don't do it often. I imagine the 35 1.4 would be better here, but 18-35 seems capable of producing nice ones at 35 1.8 ? Right now my number one used lens is my 50mm 1.8, and my 10.5mm fisheye. Any input would be appreciated! Otherwise I may just flip a coin.
