Sigma 20mm 1.8 or 30mm 1.4 - Help Please!

[Fate]

Heya all,

Im looking into buying another fast lens, and was wondering what you guys would advise out of these two.

I like the wideness of the 20mm (obviously), but its got not HSM and is pretty big size wise and its a bit slower.

the 30mm is pretty compact, very fast aperture and has HSM... but its just not as wide... i think it equates to about 47mm on my fuji.

If anyone has either, i would love some advice.

I have the 30mm F1.4. It's a very good lens...razor sharp most of the time.

I don't know much about the 20mm F1.8.

I'm not certain, but I believe that the 20mm is a full frame lens (good for 35mm film or full frame sensor)...while the 30mm is for crop bodies only. Not sure if that matters to you at all.
