So here are some pictures I took using my new sigma 85mm f/1.4 for canon. The first problem I must say is that the lens has a very hard time focusing on my 5D mark II almost impossible, I was forced to shoot all of these photos on manual focus
No I am not too good with manual focus so some of the photos may be a little off but I took this lens through some very low light tests using only natural light from the sun set around 6 PM and candles along with minor over head lights hence the reddish color.
The lens preforms flawlessly optically on Full Frame minus some color fringing and purple fringing at at f/4 - f/8 though I don't see myself using this lens at those apertures.
The build quality is amazing and nears my L lenses. The lens hood is pretty good but should be a bit longer and the extension is too long so I'm not sure
I have yet to test the lens on my 7D but I will put some photos up soon. Most of these photos were shot
5D Mark II | 1/160's | ISO 3200 | f/1.4
Let me know if you have any questions and the AF is super fast in the day but is really slow on FF at night though it works flawlessly on a Cropped sensor like the 7D.... More to come
