I'm also thinking about a 1.4 again ... I shot some nice indoor pics on xmas with my Tamron 17-50 VC (mainly because of the VC) - but a 1.4 would have been the better choice I guess. Unfortunately I left my 50mm 1.8 at home. I already own a EFS60mm 2.8 which is a great lens. So I guess the Sigma 30mm 1.4 would be the best buy for me. But I'm kinda worried that it is too wide for e.g. indoor portraits ...
I guess I must try that out.
