gwelland Posted January 7, 2010 Share #21 Posted January 7, 2010 Advertisement (gone after registration) Well that's pretty much what my last repair tech did but see below from earlier so beware ... not sure if this ends up being an issue with the front element being centred correctly or what it is but this was real for me. My 28 'cron ended up like this too. I had it looked at by a local repair shop who did indeed solve the problem in rather the same way as you describe as it turns out. HOWEVER, I hadn't used the lens for a while and actually was in the process of selling it when the buyer did a detailed comparison of my lens with another 28 'cron and it was obvious a mile off that it was now soft (well, relative to most other marques at least). I didn't notice anything other than the front of the lens rattling very slightly but I didn't notice a similar loose rear element. It's now on it's way back to Leica for readjustment. :( Link to post Share on other sites More sharing options...

Alan Philpotts Posted January 7, 2010 Share #22 Posted January 7, 2010 Graham On my lens, just the filter/hood mounting ring was slightly loose. My 28 mm is old and gets used on both M8 and M6. I swap filters fairly often - this may be a cause. However, everything else seems fine. You are quite right that if a subsequent fault appears, especially anything regarding the optical alignment, then a diy fix would be inappropriate. I hope your lens gets back to you soon.

offshore Posted January 9, 2010 Share #23 Posted January 9, 2010 It's a good diy fix to keep in mind but Leica is doing a complete rebuild on my 28 including diaphragm and aperture ring and it's coming in right under the wire for the warranty. Still mid March is a long time away. Ahh, the Ides. Link to post Share on other sites More sharing options...
gwelland Posted January 9, 2010 Share #24 Posted January 9, 2010 Leica NJ is back to their old backlog days it seems. I got notice of the coding for two of my lenses (50 'cron & 90 Elmarit-M) which were shipped out at the beginning of December - scheduled to be completed at the end of February. Luckily they did confirm that the year WAS 2010!! My 28 'cron was sent off for fix after those lenses and I haven't had a date for that yet. If the coding is anything to go by then it'll be sometime in March/April ... I can almost understand why folks send off lenses and buy a temporary replacement because this turnaround is pretty poor. I know that these are precision optics but these timeframes are pushing the bounds of credibility. Link to post Share on other sites More sharing options...
cliffp Posted January 9, 2010 Share #25 Posted January 9, 2010 I just noticed that my 28 cron had a loose front (bit between the where the filter screws in and the aperture ring). One of the 3 grub screws was completely loose. OK after tightening (no rotating inner element problem). I hope those of you waiting for your lenses to be repaired get them soon.

tobey bilek Posted January 11, 2010 Share #26 Posted January 11, 2010 This never would have happened before the cost cutter got involved in lens design. Grub screw and glue is a Vivitar or Soligor type of construction, not something one should find on world class lenses. Link to post Share on other sites More sharing options...

I agree but the alternative is coughing up (should I say throwing up) the money for the 'cron which is more than twice the price. Have you looked at Leica lens prices lately? Screw the gold standard we should have a new currency based on the Leitz lens standard. Link to post Share on other sites More sharing options...

Have you looked at Leica lens prices lately? Screw the gold standard we should have a new currency based on the Leitz lens standard. Seriously. Just checked the going _used_ price for a 28 cron. Close to $1000 more than what I paid just a year ago. Granted that's for a mint one, but still... By the way, and to draw my part in this saga to a close, received my lens back from Sherry at Golden Touch today. Seems good as new. Fast turn around, reasonable prices, Golden Touch gets a big thumbs up from me. Link to post Share on other sites More sharing options...
tdtaylor Posted January 21, 2010 Share #29 Posted January 21, 2010 This never would have happened before the cost cutter got involved in lens design. Grub screw and glue is a Vivitar or Soligor type of construction, not something one should find on world class lenses. May be cost cutting, but still, it is a $1,800 lens- not like we paid $350 for a Nikon 24 f2.8. And I'm sorry, I've about had it with going back and forth with NJ. My brand new M9 is inches out of focus, and they're trying to hoist this 3 month backlog on me! (yes, direct from the service rep, who I have now had discussion with 3 times) At this point I am wondering why I contemplated a move from Nikon to Leica- at least Nikon was only two or three weeks. PS- I just sent a lens in to Golden Touch- nice to deal with a responsive company! Link to post Share on other sites More sharing options...
nick.edwards1 Posted January 25, 2010 Share #30 Posted January 25, 2010 As many have reported here, I have had the same problem with the lens hood mounting ring. When I first noticed that it was lose I contacted Leica UK - I spoke to a technician and described the problem - I suggested that to him that tightening the 3 screws would maybe fix the problem. He told me to go ahead as that is all that they would do at Leica UK. I did as was suggested and a few weeks later had the same problem - I re-tightened the screws again and stopped systematically using the lens hood - no more problems since. The root cause for me was that the 3 screws holding the lens hood mounting ring are insufficiently robust enough to retain the ring if you always use the rectangular lens hood. The 28 Cron Asph is the standard lens on my M8 and I was using the neoprene Leica case without first removing the lens hood - I thought that this would have been OK as the hood is supplied with it's own lens cap. Best regards, Nick Link to post Share on other sites More sharing options...
cliffp Posted February 12, 2010 Share #31 Posted February 12, 2010 My hood mounting ring came loose again as well. As the lens had to go to Germany to have the focusing adjusted (along with M9) I mentioned the problem in my covering letter. They sent a quote for £240 to fix it. This seems a joke considering it is a design fault! Link to post Share on other sites More sharing options...
