mcg Posted June 4, 2009 Share Posted June 4, 2009 <p>I have a Nikkor 70-200 f/2.8 VR - my priciest piece of glass - and although about 4 years old, it has not often been used.<br /> <br /> It's recently developed a problem, which I have been told is likely due to the iris sticking and not stopping down: it's fine at f/2.8, but with smaller apertures I get increasingly grossly overexposed images.<br /> <br /> Is this a problem that many here have encountered? Is it a problem that tends to afflict some lenses rather than others? I'm bummed in that I've never had a problem with any consumer Nikkor I've owned, just now with this pro-spec lens.<br /> <br /> Also, for those who have had a similar iris problem, what sort of repair bill did you get?<br /> <br /> Thanks in advance for replies.... </p> Link to comment Share on other sites More sharing options...
bsd230 Posted June 4, 2009 Share Posted June 4, 2009 <p>If it were a cheaper piece of glass, I would say just keep working it and see if it works its way out. However, with that lens I would just go ahead have it serviced. If it is still under warranty it will be free. If not unless there are parts that have to replaced it shouldn't be too expensive. They will usually give you a price to let you know before they do any work. I want to say they charge 50.00 to evaluate it, I might be wrong.</p> Link to comment Share on other sites More sharing options...
michael_bradtke Posted June 4, 2009 Share Posted June 4, 2009 <p>I guy I work with has had to send his 70-200 back to Nikon twice for this very same problem. It will only get worse if you do not send it in.</p> Link to comment Share on other sites More sharing options...
liljuddakalilknyttphotogra Posted June 4, 2009 Share Posted June 4, 2009 <p>Moray - if you're the original buyer of that lens, then just send it in to Nikon under warranty. Five years in the US at least...<br> Good luck<br> Lil :)</p> Link to comment Share on other sites More sharing options...
mcg Posted June 4, 2009 Author Share Posted June 4, 2009 <p>Someone had suggested checking the lever at the back. I moved it back and forth for a bit, and it seems ok (for the moment!).<br> When I looked at it, the lever was stuck in the max aperture position, so maybe I accidentally got it stuck there putitng the lens on wrongly? Who knows!<br> Seems a poor show if someone else had to get it repaired twice for this, considering the price point of the lens!</p> Link to comment Share on other sites More sharing options...
ilkka_nissila Posted June 4, 2009 Share Posted June 4, 2009 <p>Yeah, it happened to my 70-200 as well. I think it cost about 100€ to fix in Finland. Like others said, Nikon USA has a 5-year warranty that may be applicable.</p> Link to comment Share on other sites More sharing options...
