Happy New Year to All! I¹ve 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. I¹ve been enjoying the 135mm very much and have recently found an Elmar 180mm f4.0 lens at an attractive price. I¹ve 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. White San Francisco, CA
