I have a Sigma 30 f1.4 prime and I think, in terms of IQ, it's on par with my Canon 50 f1.4 prime and probably a bit sharper around the edges. The Sigma 30 f1.4 is a great normal prime for APSC cameras.


This is why I don't mind considering 3rd party lenses, especially the Tokina 11-16 f2.8 as I have seen and heard some of the great results it produces. The only issue for my Trio #1 is the Sigma as I haven't been able to find much feed back and sample images on it.


Perhaps you can post a few photos from the Sigma 50-150 for me?


Thanks!
