Sigma 24mm F1.8 vs. Sigma 28mm F1.8
Likewise, I have and use often the 28mm f 1.8, but do not have nor have used the 24. Overall I like the 28 a lot for a "normal" effective focal length lens, relatively affordable, good lens "speed." I think it may be slightly less sharp than say the 58mm f 2.8 macro which is well regarded for it's sharpness, but again the 28 has a nice FOV for general shooting, macro focusing, and helps with low light.
