[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have 2 of those Canon 50/1.2 lenses, and had one cleaned and recoated by Focal Point. I have not had any of these sorts of problems with either lens. Focal Point is on the high side cost-wise, but I have never been disappointed with the work. I would be a bit put out that a CLA on a lens is only warrantied for 6 months considering how simple the diaphragm mechanism is compared to SLR or shutter-included lenses. I wonder how a lens is prone to lubricant migration? Hmmm..
