[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have a 90mm summicron M mount that was made around 1972. Removable head version, in black. It has served me well through the years. At present I have plans to send it in to be CLA and have a focus check. My question to those of you who have had the priveledge of using a later style or the ASPH latest greatest version of this optic is this: "What increase in clarity and sharpness can I expect in the f2 to f2.8 range on the latest lens over my old one. Some of you may have both lenses and can tell me. When I use the 90 it is mostly nearly wide open as I use my Nikon 105 AIS nikkor if the going isn't as rough. I am contemplating replacing the 90 eventually, so I need some incentive to get going on this. cheers gck
