Is a Carl Zeiss Jena Pancolar MC 50mm f1.8 worth it if you already have an Auto Rikenon 50mm f1.7?
I know CZJ lenses are highly regarded for their great sharpness, micro contrast, color rendition and build quality. I already have two M42 lenses: An Auto Rikenon 50mm f1.7 and a Helios 44M-5 58mm f2. I'm considering getting a Pancolar to add to my vintage lenses to use for shooting my Sony FX2. Would you say it's worth getting one despite being the same focal length?
