I have the nifty-fifty and I am in love with the kinds of images it can produce, particularly when it comes to portraits. I really enjoy the lens, but I have one problem; it is a little bit too tight for me. So I've been looking for a wider prime with similar attributes and have found the 28mm f/1.8 (as well as the Sigma 30mm f/1.4).
My question: Other than the obvious (price, focal length), how does the 28mm f/1.8 compare to the plastic fantastic especially in IQ? I've read a few reviews but nobody seems to compare the two.
I shoot on an APS-C sensor.
For bonus points: the same question but for the Sigma 30mm f/1.4.
