I just got back from In[FOCUS] in New Orleans which was a very inspirational event. While I was there I filmed a piece with a rep from Canon. We went through a series of primes lenses (14mm rectilinear, 15mm fisheye, 35mm 1.4, 50mm 1.2, 50mm 1.4, 85mm 1.2, 85mm 1.8, 135mm 2.0, 135mm 2.0 with 1.4 tele converter which you lose 1 stop and it became a 2.8) that they had. As we switched each lens the only thing that changed was the iso. Each lens was left wide open and we were around 3ft from the subject. All was shot on a 5D. It was also shot in 24P.

Here is the video Canon Prime Lens Comparison with 5D on Vimeo

Brilliant, Thanks for those!

Nice comparison clips on the Canon primes, Michael...although maybe I'd have picked a nice looking female to focus all that lovely glass on; and to help maintain interest levels... :)
