mikeyt Posted March 9, 2011 Share #1 Posted March 9, 2011 Advertisement (gone after registration) I have a 2.8 90 from around 1969 which has a loose front element and a slightly sticky aperture ring, so opening up the aperture risks unscrewing the front of the lens... are there any suggestions apart from 'do it up as tight as you can and be careful when you use it?' many thx mike Link to post Share on other sites More sharing options...

Xmas Posted March 9, 2011 Share #2 Posted March 9, 2011 Hi If it is a lens retaining ring - that is loose - I'd never do them up tight, there is always the risk of cracking glass... If it is a lens assembly, it should be ok to use some effort, but an aperture ring needs to be free to turn only limited by the click idents, suggest one of the pro repair people... or if you are practical strip and rebuild with trace of low outgas grease, but accept that there will be lots of internal dust afterwards, unless you have a pukka clean room...

lars_bergquist Posted March 9, 2011 Share #3 Posted March 9, 2011 It is not uncommon that the front cell (not the front element as such) works loose. It is screwed in place and normally held by a couple of setscrews. Any competent camera repairman – not necessarily Leica – should be able to fix this. It is a good idea not to try this yourself.

lct Posted March 9, 2011 Share #4 Posted March 9, 2011 'Fat' or 'thin' Tele-Elmarit? If it is the 'fat' T-E the lenshead is not detachable so i would not touch it if i were you. If it is the 'thin' T-E, the lenshead is detachable from the focus mount so suffice it to screw it onto the latter that's all. Link to post Share on other sites More sharing options...
lars_bergquist Posted March 9, 2011 Share #5 Posted March 9, 2011 Not correct. It was the first 90mm Elmarit (1959–74) that had a detachable lens head (for use on the Visoflex). The front cell was unscrewed from the focusing unit and screwed into a universal focusing unit 16464, which was bayoneted into the front mount of the Viso. No Tele-Elmarit had a detachable head. This is true for both the "fat" five-element Tele-Elmarit (1964–74) and the "thin" four-element version (1973–89). Their front ends are supposed to stay put. A competent repairman – not a reformed key-cutter – should do the job. The old man Link to post Share on other sites More sharing options...
lct Posted March 9, 2011 Share #6 Posted March 9, 2011 Theory and practice. Mine is detachable Lars. Link to post Share on other sites More sharing options...
lct Posted March 9, 2011 Share #7 Posted March 9, 2011 Advertisement (gone after registration) The Elmarit (# 11129) has a detachable head as well. Not the same lens as 'fat' and 'thin' Tele-Elmarits (# 11800). Link to post Share on other sites More sharing options...
lct Posted March 9, 2011 Share #8 Posted March 9, 2011 But the Elmarit's lenshead can be used with the Visoflex. Not that of the 'thin' Tele-Elmarit afaik. Link to post Share on other sites More sharing options...
