Now my 24-70 F2.8 also needs barrel replacement

[sammedia]

•The Nikon 14-24 f2.8 and Nikon 24-70 f2.8 both made the list, and every single repair was the same: zoom ring stiffness to the point they are difficult to use. They both have a similar iinner-outer barrel zoom mechanism, so we assume there’s a common issue with them. These are rather recently introduced lenses, so we’re watching to see if the rate gets higher as more copies age — right now our average copy is only 9 months old.

I guess this Issue are well known, design flaws? I think Nikon will have to come out with something, Cos they can't expect us to pay for such a high repair cost everytime.

Nikon should hire more competent mechanical engineers and fire their batch of mechanical engineers who did the design for the 24-70, 14-24 and 18-200! At this rate, I'll start lose respect for Japanese engineers whom I have quite highly regarded to be among the best in the world. I still have very high regards for German engineers!

lsisaxon: Can't agree with you more. Spending thousands of dollars and still got to worry about it having problems, the sense of security is as good as none.

thanks, for bringing this up. will settle for third party for now.

The problem is both Nikon 14-24 f2.8 and Nikon 24-70 f2.8 are the very best zoom you can find in the market, once you try it, you would not settle for anything less.

That why I repair 3 time on my 24-70mm, still never give up hope.:sweat:

anyone got any idea how much its going to cost to replace the zoom ring and the rear barrel part?

dropped my 24-70 by accident and now the zoom is stuck at 50mm. opened up and found that the lens is ok less the zoom and read end barrel is warped and thus the zoom ring jam.

I always thought N 24-70 is always the most wanted lens for FX system, now really got to consider canon system

 

[thevar]

whats the cost of replacing the parts ? my lens is starting to be stiff! tks.

Sounds like this problem is much more widespread than originally thought ?? :think::bigeyes:

If it's under warranty, give a call to NSC. If it's out of warranty, try to ping David aka Fatigue in CS..

 

[nixontkl]

mine was accident drop resulting in my zoom to jam. my total repair cost abt $1100 parts and service together. replacing the entire barrel assembly. the parts cost approx 900 b4 GST. boy the parts are expensive. but still LL have to repair.

Hey guys, i just checked my copy of the 24-70 which was just bought recently, just under 2 months ago. And yes i have not even mounted it on a cam yet to take it out for a shoot, i know really busy lately havent got time at all. Eitherway, ive been pretty shocked by the number of threads both old and new surfacing in regards to the 24-70's rough zooming.

So anyways i just took mine from the cab to fiddle with it and realized it isnt really buttery smooth(my expectations are pretty high for this lens in terms of smoothness), well it zooms fine, a little stiff at the 35-24 Region and just climbing the far 70 end. Doesnt lock or Jam however at the 70 end, if i were to slowly and i mean really slowly (1 Degree decrements, minute adjustements) down from the 70 end i would get slight little bumps (somewhat comparable to little pulsed grinds). After about 5 Degrees of rotation of the Zoom ring it goes back to normal smoothness and is smooth throughout the mid end.

I have never really played with too many 24-70's or defective ones for that matter to really know where that line is drawn, between an acceptable (QC passed) copy and a copy that has this infamous issue of grinding/ Jamming/ Stiffness to know if i should send in my copy ASAP. Never really seen any Vids online or illustrations of this particular problem.

Hope yall can throw me a little advice on what to do and if my lens is prolly a Lemon of a copy and should be sent in for a replacement if it does get worse. Thanks very much guys, very much appreciated! ~SB

your lens sound fine, the zoom is not a perfect smooth thru out. there is a little diff near the 50mm mark. the diff in smoothness most prob comes from the way the helicoil (not sure the speeling correct or not) is design. this heli thingy is the part that push or pull your front glass in and out when zooming.

Strange. My copy was smooth throughout even with minute adjustments.

Wow, you are really very detailed with your descriptions. :bigeyes:
When you have spotted a good scene, you would have zoomed so hard that you can't tell that there is a bump or hump...

ur copy must have been extra smooth.

24-70 the zoom is a little special as the lens is most extended at 24mm and shortest at 50mm and at 70mm its a little bit extended. the change in direction of the tube inside extending at the 50mm mark there be a little nudge, some may feel it some dont.

anyway a word of causion, the zoom ring and the area where your serial number is, those 2 ring are very critical. never never knock these 2 ring. they are metal and once there is a slight deform to the ring, your zoom will not be smooth and may jam. learn it the very painful way when i drop mine accidently, took apart the lens and found that the 2 ring have to be prefect in order to have a smooth zoom, the 2 ring fit together very perfectly with little margin of error thus any knock to either ring and caused either ring to go deformed maybe less than a 1mm change and u be having a screwed up zoom. the 2 rings are made of what metal i dont know but they are pretty tough, but metal is still metal they can deform if the knock is strong enough.

Strange. My copy was smooth throughout even with minute adjustments.

That why I repair 3 time on my 24-70mm, still never give up hope.:sweat:

You are freaking me out..
Luckily I hav no need to send mine yet..:sweat:

Although my 17-55mm f2.8 is of a different league. But I would like to share that I have repaired twice for this lens as I have dropped it due to accident.

Haha i do my best on my part to be as descriptive as possible, so as to avoid any misunderstandings or difficulty in trying to understand what im conveying here. Also to avoid the "Grammar Police" around here :bsmilie: . Yeah true, although im just a little worried that it might degrade over time and get worse, coming to the point that many other Photog's have experienced with the lens zoom locking up at some point.

Strange. My copy was smooth throughout even with minute adjustments.

I'm just hoping its me being paranoid or having too high an expectation of the term "buttery smooth" being used to describe the zooms smoothness by many. Gonna head out to MS, a coupla blocks from my place to have a sample with their copies in store. See if any of them do exhibit any of the symptoms of a lemon in the making :bsmilie:

Does this get worse over time? Or will it just be like this throughout? Ive heard of Photog's that have had some mild symptoms exhibit in the first few days to weeks of usage finally escalating to the point whereby the zoom would just lock up or get extremely stiff. And yeah, the helicoil does indeed make the lens a little stiff or tight around the extreme corners but im just worried bout that mild grinding im experiencing

Thanks for all the input guys! Very much appreciated once again! ~SB
