imagehause Posted March 16, 2005 Share Posted March 16, 2005 Hi, I got 40MM 1.4 Nokton and two month later the element/glass assembly loosened so much , that it is almost about to fall out... bringing it back to Photovillage this week to be either replaced or get my $$ back. It started of with a little play in the front and then it got so loose almost falling out, unusable. Guess for the price you get the build quality. Glad I have not sold my 40 Rokkor in the first Nokton euphoria. Enjoyed my time with the lens (however brief) and I like the results.

kirk_teetzel Posted March 16, 2005 Share Posted March 16, 2005 A few bad ones don't represent the quality of the whole. Link to comment Share on other sites More sharing options...

ronald_moravec1 Posted March 16, 2005 Share Posted March 16, 2005 That is what happens when you glue things together. seems to be the current standard though, as Leica no longer wants to make retaing rings and threaded recepticles either. They are doing a bunch of glue too. Don`t grab the front of your 35 to lock the bayonet. Link to comment Share on other sites More sharing options...
jtk Posted March 16, 2005 Share Posted March 16, 2005 There's no way an aluminum lens body can last as long as bronze. CV build quality is obviously not comparable to Leica/Canon/Nikon. On the other hand, CV actually makes a 40 1.4, if that's important. You can see the impact of mechanical cheapening on resale prices when you compare Canon FD lenses with old and "new" mounts, or when you compare the EBay prices of new CV lenses with comparable old Canons.

rover Posted March 16, 2005 Share Posted March 16, 2005 The Leica 35s are glued, I believe the CV lenses are threaded and unscrew from placing and removing filters and hoods. Is that what you think happened Peter? Sherry repaired my 35 Summicron very quickly and very inexpensively when it arrived with a loose front assembly. Unfortunately, the repair is to reglue it, so I keep it for B&W photography with a yellow filter and hood permanently attached just to be extra careful with it.

ben z Posted March 16, 2005 Share Posted March 16, 2005 My 35 Summicron front was also slightly loose when I bought it (the aperture index had drifted from its correct position opposite the focusing mark), however that model is secured with a retaining ring in the back, so 10 seconds with a spanner wrench and I fixed it. I think it's just the more recent (like 1980 on)lenses where some are glued. Link to comment Share on other sites More sharing options...
benjamin_shapiro2 Posted March 16, 2005 Share Posted March 16, 2005 My CV40 is doing the same. It's gotten much worse since purchase. It's going back to Gandy as soon as he gets back from Japan. Great glass, though. Ben Link to comment Share on other sites More sharing options...
jtk Posted March 16, 2005 Share Posted March 16, 2005 I've never heard of mechanical problems in pro SLRs that rival those on this Leica forum...why? Superior quality control from Nikon/Canon/Pentax? No wonder Leica's in trouble! Link to comment Share on other sites More sharing options...
lee_shively Posted March 16, 2005 Share Posted March 16, 2005 The Nokton's are not Leica lenses, John. Link to comment Share on other sites More sharing options...
huw_finney Posted March 16, 2005 Share Posted March 16, 2005 I had the it with a CV 35 pancake M, just tighten the holding ring, the same for the 40 too. The rings are a bit recessed, moreso on the 40. Slightly crap pictures, but you get the idea.<div></div> Link to comment Share on other sites More sharing options...

huw_finney Posted March 16, 2005 Share Posted March 16, 2005 You can push them round with a small screwdriver until you can make a proper tool or get one. Nothing to go out of line unless the whole optical unit drops out and you lose a spacer! Link to comment Share on other sites More sharing options...
huw_finney Posted March 16, 2005 Share Posted March 16, 2005 Ronald, I have had the 40 and 35 apart, not one bit is glued. There is some locking varnish on the odd bit though. Link to comment Share on other sites More sharing options...
h_c Posted March 16, 2005 Share Posted March 16, 2005 People with problems, is this the SC or Multicoated version you are having problems with? Link to comment Share on other sites More sharing options...
uuronl Posted March 16, 2005 Share Posted March 16, 2005 I'm not sure I'm understanding which bits are loose. I haven't noticed anything with my S.C. version but I'll happily check and report back... Link to comment Share on other sites More sharing options...
huw_finney Posted March 16, 2005 Share Posted March 16, 2005 It's not bits that are loose, but bits that can loosen with time. Link to comment Share on other sites More sharing options...
douglas k. Posted March 16, 2005 Share Posted March 16, 2005 Hmmm...So I guess Voightlander IS up to Leica quality. Link to comment Share on other sites More sharing options...
huw_finney Posted March 16, 2005 Share Posted March 16, 2005 Not quite, CV use bent metal bits where Leica would machine out of solid and some of the helicies are aluminium, not realy a problem with new lubricants though. Even so they are pretty close. Link to comment Share on other sites More sharing options...
socke Posted March 16, 2005 Share Posted March 16, 2005 Peter, sure you didn't buy a russian fake? <br> The correct spelling is <b>Voigtländer</b><br> <br> <br> Sorry, couldn't resist :-) Link to comment Share on other sites More sharing options...
monsoonphoto.net Posted March 16, 2005 Share Posted March 16, 2005 Hmm, I've got an SC, and no problems to report (except that the focusing is still somewhat stiff. I need to use it more!). Link to comment Share on other sites More sharing options...
imagehause Posted March 16, 2005 Author Share Posted March 16, 2005 Ok, I am slightly mechanicly inclined and I thought of tightening the screws and looked around for a simple solution. Could not find any and all screws were tight. Mine is the MC version and it seems to be internal. Guess it needs to be taken apart and retighten/reglued. The part that was loose is the whole lens/glass assembly (part that you would unscrew in the older leica lenses for viso use). The focusing helicoid in which it is housed seems fine and sturdy. Rich is sending the lens to Japan to be fixed.. 2 to 3 weeks turnaround. Will report back on how it was solved. Peter Link to comment Share on other sites More sharing options...

hugon Posted March 17, 2005 Share Posted March 17, 2005 ez, try holding down the alt-key n at the same time press on the numerical part : 132. that'll produce ä. Link to comment Share on other sites More sharing options...
socke Posted March 17, 2005 Share Posted March 17, 2005 Peter, I entered HTML. <br> To get an ä you enter ä an ü is ü ß is ß and so on.<br><br> This way you get £ and € as well :-)<br> <br> But, though fun, it's more work :-( Link to comment Share on other sites More sharing options...
