In past I had the Sigma & Canon 15 2.8
Are there any other cheaper ones like Rokinon, Venus optics, Irix,... ?
It's for partyphotography in dark clubs, so also f2.8.
I guess i'm not going to miss anything as a lot is sharp on a uwa.
With the ones above I could take pics without looking at f2.8 and everything was sharp.
I usually work at shutterspeed aperture, 1/30 or 1/50 with flash for great lightning effects.
