Upload & Sell: Off
i bought the 24 f1.4 first, its an awesome piece of glass, unmatched by any other 24mm option, sharp edge to edge, no distortion in real world usage, great af, amazing optics.
I then bought the Nikon 35 F1.4G and its rapidly becoming my favourite lens. Tack sharp at all apertures, very accurate af (maybe a little slow, compared to say the 24-70 but ive had no problems following a bride and groom around a dance floor only lit by flashing disco lights).
recently had a look at the Sigma 35 and dont like it. A friend bought it and we compared them on a shoot and he is selling it for the Nikon.
The Nikon is as sharp (regardless of what some lens tests say), its got more accurate and stable af with all my af points on the D800, its weathersealed and it feels better to hold. The ridges on the Sigma feel terrible and they atttract dirt like you wouldnt believe. I dont think the Sigma's finish will be as durable over time, but thats just my opinion and who knows if it will have to be rechipped to work with future bodies.
the 24, 35 and 85 F1.4's replaced my 24-70 and ive not regretted the move for a second
