Re: Faster Glass ...or Image Stabilizer?

"Hold on ... an f/3.5 exposure, even stabilized at half a second (let alone 1/20 sec) ... isn't going to compare to the amount of light coming through an f/1.4 lens at 1/40 sec."

1/2s and f/3.5 captures (1.4/3.5)² x (20/2) ≈ 60% more light than f/1.4 and 1/20s ! (unless one crops the 15mm f/3.5 photo)

The 32mm f/1.4 would definitely benefit from image stabilization (and in the future I am sure there will be Eos M cameras with image stabilization). I usually choose 1/125s because I am not always able to hold the camera extremely steady (it's exhausting). And for landscape photos in extreme low-light conditions I even managed to get a sharp 1/20s photo without any help, but it's still quite noisy, partly due to the vignetting at f/1.4.
