erickpro Posted January 14, 2006 Share Posted January 14, 2006 Like the title says. I noticed the ring was cracked a few months ago. I was shooting some pictures of the moon and it snaped. I read an old thread where Shun had to pay around $200 to www.authorizedphoto.com to fix his macro lens. It seems like I'm gonna have to do the same unless someone recommends me something else. I really do not want to pay $200 since I just bought a 50mm 1.2 Ai- S and should recieve it next week.<div></div> Link to comment Share on other sites More sharing options...
mark_jordan3 Posted January 14, 2006 Share Posted January 14, 2006 I have the same lens...as far as I can tell the piece is plastic. It's really a light duty part...if it were mine I'd probably try superglue; care is a must as you wouldn't want the glue to ooze into the inner area of the ring. What's not apparent to me is how the part is replaced short of disassembling the lens cowling...that is if somehow you could buy just the replacement part in the first place.

erickpro Posted January 14, 2006 Author Share Posted January 14, 2006 I tried super glue on other things and I ALWAYS end up with unmovable parts. That super glue alsays gets where I don't want it to. Link to comment Share on other sites More sharing options...
ShunCheung Posted January 14, 2006 Share Posted January 14, 2006 That design flaw on the 200mm/f4 AF is quite well known. Nikon should never have used a plastic ring to control AF/MF. There are points on that ring that are hollowed out to engage/disengage the AF mechanism. Unfortunately, those hollowed out areas are weak points on the ring and that is why they break fairly easily.

mark_jordan3 Posted January 14, 2006 Share Posted January 14, 2006 Have you tried the newer superglue "GEL"?...much easier to control. The regular stuff is horrible, half the time I'd glue my finger tips together!<br>I guess even if you're successful in gluing it; it's more or less a temporary fix, but perhaps it would tie you over until such time as you could justify getting it done in combination with a lens CLA to absorb some of the labor your paying out. That part can't cost more than $10-15.<br> Link to comment Share on other sites More sharing options...
alan_chan4 Posted January 14, 2006 Share Posted January 14, 2006 Superglue of any form would never be able to hold anything under stress, especially when the contact is so thin. It is an invitation of more expensive repair later on. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted January 14, 2006 Share Posted January 14, 2006 The A/M ring on my 80-200/2.8D AF N also broke and it was repaired for free by Nikon. Perhaps you can send it to a place where the repair cost isn't so high. Apart from the 80-200, the 200 mm Micro and 14 mm AF-D are known to develop this problem.

erickpro Posted January 14, 2006 Author Share Posted January 14, 2006 Nikon won't repair mine. It's gray. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted January 14, 2006 Share Posted January 14, 2006 What you meant was that Nikon USA won't repair it. Nikon Japan or Europe will, as will independent repair shops. Link to comment Share on other sites More sharing options...
erickpro Posted January 14, 2006 Author Share Posted January 14, 2006 Correct. Link to comment Share on other sites More sharing options...
daniel_binkard Posted January 14, 2006 Share Posted January 14, 2006 Was your free repair simply under warranty or did Nikon make an exception for this particular problem? I just checked my 80-200 and it's got a crack in the same place as Calderon's, so I guess it's only a matter of time before the ring breaks.

ilkka_nissila Posted January 14, 2006 Share Posted January 14, 2006 It was Nikon in Finland, they never charged me for repairs for some reason. I think they don't have a service centre any more, so it needs to be done by an independent shop. I suspect that everyone is just buying their lenses online now from the US (because the price difference reached the point of being ridiculous) so their business must have reduced so much that Nikon don't want to have their own repair shop. However, I'm sure there are places in Europe (as well as the US) where the simple repairs like this aren't as expensive as Nikon USAs. Just ask around. By the way this is a clear design defect and it breaks with normal use so it's clearly something Nikon should fix for free. Link to comment Share on other sites More sharing options...
tomweis Posted January 14, 2006 Share Posted January 14, 2006 Mine's broken twice. It should be make of machined steel, cast magnesium, or something along those lines. I sent the lens to Nikon. It cost $207.54 and was listed as a B2 repair.Overpriced in my opinion for a part that shouldn't break at all considering A) I hardly ever use the lens, and B) I treat it (and all my gear) with care.

guts80 Posted January 15, 2006 Share Posted January 15, 2006 Another person with a cracked M/AF ring on the 80-200/F2.8D. However, thankfully I'm living in Hong Kong so the service / repair center is only a relatively short ride away. Cost was only 900 HKD (~113 USD), but it did take about a month for them to repair it (they had a lot of backlog repairs still pending at that time....). As far as I can tell, the lens will still operate in M or AF it's just that they won't lock into place. THUS you can use tape to secure it in one or othe other position and it should operate as normal. Link to comment Share on other sites More sharing options...
erickpro Posted July 28, 2011 Author Share Posted July 28, 2011 <p>After 5 years I still use that same lens and it's still cracked. Just used some industrial strength tape.</p> Link to comment Share on other sites More sharing options...
