I think Steve summarized it very well. However, there is one more issue with the Rokkor. Although it will work well with the 20d, the lens will interfer with the mirror of the 5D, and likely the 5DII, if it\'s focused to infinity. For this reason many will undercorrect the Rokkor during the conversion. Focus can be achieved out to ~30ft before the mirror becomes an issue for most 5D\'s. Some will modify the 5D\'s mirror to allow the use of lenses like the Rokkor.
