Re: EF 400mm f/5.6L USM image quality

You can certainly use a 400 at 1/250 without IS and you’ll get a lot of acceptable results, but IS will result in more sharp images.

i shoot mostly at 1/1000 and above (to freeze action) and I find negligible difference between IS and non IS.

i find the canon IS on my 100-400 II is much better than the IS on the sigma and TAMRON 100-400 contemporary lenses, which I also owned.
