Hi,

I have a 40D / Sigma 8mm 3.5 and NN3 that I have been using to make 360 Panos. Now I am looking at picking up the Canon 5dMII, an NN5 and another lens. Specifically, I was looking at the Canon 16-35L, but would the 15mm be a better choice? Does it require any tilting on a full frame (or just 6 around)? I'm keeping the 8mm, but I have heard it has mixed results on the 5D, hence the new lens idea. I want to be able to take fast panos (like at the beach where waves are moving) and indoor architecture with better IQ than the 40D/8mm. Anyway, any thoughts or advice would be most appreciated.
