Canon 28mm f/2.8 LTM - how to take off front element?
I'm cleaning the aperture blades of a Canon 28/2.8 LTM lens and I'm done with the back of the blades and also relubricating the focusing ring. However, the usual front retaining ring to take off the front element is hard to see on this lens. No small screw to unscrew on the side of the outer ring and no small dumps for the spanner anywhere in front. I'm not sure if it should just be unscrewed, - if so the recessed black inner element or the outer chrome ring...?
Have any of you disassembled the front element of this lens before and how did you manage?
Thanks in advance!
