I am a bit torned between the 85 1.8 and sigma 50 1.4 non art. I would like to ask 70d users if they have the sigma 50 non art on them or maybe had been able to test on their 70ds? I am more in favor for the sigma 50. My question is if its working properly with the 70 because I had read some compatibility of the 70d with some third party lenses. Tried to asked this question on the lens sample photo archive but I am not getting any answers. I cant try it myself here due to the unavailability of the lens in my place. The nearest market for this lens is 600 miles from my town. My friends dont have it too. Thanks in advance.
