Topic: Spiratone 400/6.3 - Dismantle
I very recently acquired this long thin telephoto - manual 12-bladed (!) diaphragm, Nikon T mount. Anyway, the rearmost element is pretty cloudy, so I'd like to see if I can take it out and clean it. taking the T mount off doesn't really gain me anything - the element is recessed about 2" in. The only place where I might gain some entry are three small screws situated just forward of the aperture ring, and just behind the focus ring. I suspect that loosening these will allow me to either slide off or unscrew the rear half of the lens barrel. I've never dismantled a lens before, and this seems like a good place to start - didn't really cost me anything. Has anyone taken one of these apart, and if so, where to start? Failing that, anyone have any general advice foe opening up a long telephoto? Thanks in advance. DC.
