Thinking of purchasing 2 Zeiss primes for my 7D, and then the Canon "L" 24-70mm f2.8 to be used as well for photos. As for the primes looking at a 50mm, and a 25mm. What do you all think? Good range or is this just a waste of money? I love the smooth focus barrel and long focus distance on the ZF glass. I will most likely buy Nikon version with the adjustable Iris ring and then use a Canon to Nikon adapter. Wish I had enough for the real CP.2 lenses that just came out but those things cost as much as a car!
