I am interested to see how much coma the 20 f/1.4 has. If minimal....it is going to be tough to keep it out of my kit. But I may wait a bit. See if Canon does something slightly wider. This is mostly because I am happy with the 24 f/1.4. So far, great lens.

So, before picking up the 24 f/1.4 VCM, I would have called a low coma fast 20 mm lens a near perfect compromise, and I still might. But now, I wonder if I keep the 24 mm VCM, would I go with two lenses, something in the 14-18 mm range, if Canon were to release it. We'll see. Shoot 'til you need something. Right now I need very very little.
