I just recently acquired a Helios 40-2 85mm f1.5 lens Nikon F mount. I've been doing a little hunting online but have not come across much for this lens in a Nikon mount. Does anyone here know much about these lenses? I'm not really sure if I should keep it or get it in the hands of someone that will use it more than I would. I don't tend to shoot a lot of 35mm nor portraits! Anyway, if you have thoughts/experiences with this lens I would love to hear what you think of them.
