I bought the Canon Ee-S Super Precision screen: http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=402221&is=REG&addedTroughType=search :: the Ee-S Super Precision focusing screen is designed to facilitate :: manual focusing with high-speed lenses (f/2.8 or faster). The Ee-S :: screen has finer microlenses than the Ee-A or Ee-D options, along with :: a steeper parabola of focus to make the image pop in and out of focus :: more vividly in the viewfinder; however, the Ee-S focusing screen is :: not recommended for slower lenses because it is not very :: bright. Performs just as advertised. My slowest lens is a 135/2, so I don't know how much darker it gets with slower lenses. Focus snaps fairly quickly with the 35/1.4, and that's why I really bought it. I wanted to be able to focus wide angles more accurately. I wanted it to be more M-like. :) I did not have trouble manually focusing at all with this screen...even in very dim light. -- Eric http://canid.com/
