OK I'm sick of trying to find a walkabout camera. None of them work for me, tried the Fuji X100 (want to buy one?), the Canon S100, a G12, etc. I just end up wishing I had my 5DMKII. Now there are situations where for weight and threatening considerations a smaller rig is preferred. So ... I need a small lens for my DSLR, ideally a wide angle.

I have a 50/1.4, which isn't that great. Slow to focus, IQ ... maybe my version has problems, it got touchy after some sand grains got in it, probably not worth trying to fix. Plus it's 50mm and too tight for me.

My dream focal length is 20mm but Canon seemingly has no good primes in that range. I don't like to rent, I prefer buying and deciding as it takes me months to figure out a new lens. So ... recommendations?

• Lens ideali around the size of the 50/1.4
• Prime
• Ideally wide, at least 24mm

Maybe the new 24IS? Dunno ...
