I havent heard of the 180mmf4 but I have a 180mm f3.4. It's a stellar lens, the best of the best. It's also easy to handle although it lacks a tripod mount. Of course, that is a testimony to its light weight and compact size. I think this lens can be obtained relatively inexpensively nowadays. i had paid $1300 CAD for it about 10 years ago.

I’ve been lurking here for several months after getting hooked by the R system. I currently shoot an R6 with the 35mm f2.8, 50mm f2.0, 80mm f1.4 (perhaps THE reason to own an R body!), and 135mm f2.8 lenses. I’ve been enjoying the 135mm very much and have recently found an Elmar 180mm f4.0 lens at an attractive price. I’ve looked online and have had a difficult time finding much information about it at all. Does anyone here have experience with this lens? Any pro or cons I should be aware of? Any praise or insults to hurl in its general direction? All input is much appreciated. -J.
