Morning everyone, A while back I mentioned here that I had come across a dusty Contax RTS 35mm camera and bought it inexpensively. It needed a new battery and some cleaning but it works well, I'm not finding any issues but so far haven't used it often. I was slightly disappointed in that it came with a Yashica 35-80/3.5-5.6 lens which if I recall was a budget option to the Zeiss lenses also in that mount. Again, no big deal, it has no fungus, scratches or mechanical problems. The aperture isn't sticky or anything. The variable aperture is a feature I don't care for but could live with. Yesterday I found a Zeiss T* 40-80/3.5 in this same mount for about $100. Is it really a noticeably better lens? I recall reading back in the day that Zeiss is high end and that has stuck with me ever since. Nearly all of my other glass is Nikkor and is quite good. Will the Zeiss impress me as well? Has anyone seen other Zeiss glass or maybe Yashica as well in longer prime or zoom setups? I don't shoot nearly as much film as I once did but I enjoy it and have a good darkroom so from time to time I still pick up a film body and this one might work for some nice portraiture. No motor drive so I will have to slow down and think instead of spray and pray but that's a good thing. Or am I insane..... Rick H.
