Hello, I am a newbie on this site and I've been overwhelmed at the wealth of great Contax information rushing towards me in the few hours I've spent trying to absorb it all. There's lots of good stuff here and I thank you all for posting your thoughts. However, I have a dilemma that I hoped some of you might weigh in on. I own an RTS II body that I've used with great results for years, mostly with a 70-210mm f3.5 zoom. I also carry a TVS to cover the wide angle to normal range, so I have never felt the need to own a lot of prime lenses. Sadly, the RTS II died last year and I've had a hellish time (6 months and counting) getting it repaired locally (Philadelphia). With no usable SLR, I panicked and purchased an excellent used RX on eBay. I'm a little intimidated by all the features but I'm struggling to learn them. Recently I learned that I have a chance to visit Alaska this summer and I hope to do some wildlife photography there. I don't think the 70-210 zoom will be up to the task, so I've been thinking about purchasing a 180mm f2.8 and a Mutar II to add some distance to my lens selection. Does anyone have experience with this or other mid-length telephotos/Mutar combinations? I really don't want to spring for the really long lenses (300mm+) because I just don't see myself using them much outside of Alaska. Any suggestions?
