Hello: This is my first post to the Rollei List, though I have followed for some time. There is a 80/2.8 Planar for sale at my local store in good shape, although I have been looking to no avail for a 75/3.5 planar/xenotar. My question, in short, is am I splitting hairs in holding out for a 75/3.5 when a serviceable 80mm is at hand? Here's my thinking: I've come over the years to prefer slower lenses for their lighter weight / easy handling and less pronounced out-of-focus areas. But I'm wondering if either of those considerations is that significant when considering the 75mm v. the 80mm planars or xenotars? If not, I'll happily purchase the local 2.8 planar, but since I don't have a 3.5 to compare it to, I'm a bit at a loss... Thanks for any counsel and experience you can offer.
