Ricoh LTM lenses - CLA?

[sepiareverb]

Wondering if anyone has had a Ricoh LTM 21 or 28 lens opened up for haze removal? I know the Rollei LTM and a couple of CV lenses cannot be opened for cleaning, hoping this is not the case with the Ricohs.

I have personal experience with the Ricoh LTM 21. The rear optical group is a sealed unit. If there's haze in that, it cannot be cleaned. The 21mm I bought had haze there, and after attempting to clean it, I gave up and returned the lens. I think the Ricoh LTM 28 is the same. Both lenses are notorious for developing haze.

Thank you. That’s what I was afraid of.

I don't know anything about Ricoh lens for LTM, but I have a Canon Serenar 35mm f3.5 that is prone to haze. And opening it once and cleaning is not lasting a year. Someone here said it was the glass formula. Whatever, I open it before every use and clean the lense surfaces. Luckily for me, it is easy to do this. Otherwise, this lens is really nice: well built, strong aperture leaves, smooth operation, and very ergonomic focusing and aperture controls.

The Rollei LTM lenses may be the same in that regard, they all seem to haze up.
