Nikkor 18-200 VR DX Zoom problem

Colin_D - 19 Feb 2007 09:41 GMT As a Canon devotee, I said I would post this query from my D200-owning friend (Greater love hath no man than this ... {:-)
He bought a new Nikkor 18-200 VR DX lens for his D200, but it has an annoying problem. If he tilts the camera down to check the lcd screen, the zoom falls forward to the long end under its own weight. A second lens, after much hassle with the suppliers, was obtained - which did exactly the same. If he checks the screen, or if he is shooting at an appreciable down angle, the lens slides out to full zoom all by itself.
Does anyone know if this is characteristic of this lens, or know of a reasonable fix, short of rubber bands? The agents say it is not fixable, period.

"I should note that some users claim it is loose and subject to zoom creep; that isn't the case on my sample."

Problem solved. I have the same lens, and find the lens creep the only annoying behavior of the lens. Otherwise, it is a joy to use. I'm interested in the rubber band solution you refer to. Could you please elaborate on the size of rubber band you use for this fix and exactly where on the lens you place the band?
Thanks.
Jim Thurman - 19 Feb 2007 20:00 GMT This is fairly common behavior for this lens. If you have it zoomed all the way back to 18mm, it typically doesn't creep, but if you zoom out any at all past 18, and point it down, it will probably creep out toward the high endof the zoom.
To avoid this while carrying the camera, just zoom back to 18mm or use the rubber band solution mentioned earlier.

It would be great if someone could elaborate on the details of the "rubber band solution" approach. I tried to guess the missing parts myself and it didn't seem to work very well. Firstly, what exactly are you using as a solvent? I used gasoline, since this is the first thing that comes to mind when one needs to dissolve rubber. The solution turned out as a sticky goo (BTW, isn't that how rubber glue is normally made?), but I assumed that this is the whole point. The second question is about where exactly I'm supposed to apply it. I put some on the exterior surface of the lens barrel. And then some on the inner tube, and also applied a relatively even layer of the solution to the front element. Now it indeed feels like the lens is at least partially cured of the creep problem (hooray!). But since I used the solution in three different places at once, I don't know which one actually worked. (Stupid. Should've tried them one after another.) Unfortunately, it comes with a couple of more-or-less serious disadvantages. For example, it's been more then a week, but the solution on the outer barrel is still very tacky. It collects dust, dead insects and sometimes picks up much heavier objects. Yesterday it took me more than 15 minutes to pull the lens out of my photo bag. (The fun thing to do is to slam it into a wall - it sticks and then slowly creeps down to the floor.) Also, because of the goo one the front element the image quality suffered. It is not really that noticeable, since it was a Nikkor to begin with and they all perform as if they have goo on the front element out of the box, but I know it is there and it kind of bugs me. It would be great if someone would tell me what I did wrong, if anything. Thanx.

That's the ticket. Not only fixes the creep problem, but makes it a nice soft-focus portrait lens. Really, really soft. Perfect for shooting those ladies who don't just object to wrinkles but rather the whole appearance of their faces.

Look at the lens, see the window that shows the distance setting, you want to have a fairly loose fitting elastic band just ahead of that, it will provide a little friction to discourage zoom creep.
You want it overlapping the edge of the zoom ring and that portion of the lens immediately behind it. Its the only spot that will work.
The diameter of the lens is about 3 inches, a 2 inch rubber band is just about right, its about a 1/4 inch wide. Find one that is a nice bright colour, folks will think its something exotic and will ask you what its for and where they can get one. Be inventive, lies are more believable than truth.
Experiment, you will not break anything. If it breaks, replace it, very cheap.
I carry my camera hanging behind me, I found the lens always zoomed out, putting on the rubber band solved the problem. Its amazing what a little bit of rubber can do.

Its amazing what a little > bit of rubber can do. Thanks for the reply. Since my post, I did a bit of additional research on the subject. In addition to the rubber band solution, I read about another solution to the problem using tape. I gave this a try, and it seems to have solved the problem without a couple of the negative issues associated with the rubber band solution. The tape solution goes like this:
1. Extend the lens to maximum zoom.
2. Using common household electrician's black tape, cut a length just under 1 1/4".
3. Attach the strip of tape longitudinally (front to back) on the outside of the inner-most lens barrel (farthest away from the camera body). I attached mine to the top of the lens
4. I also ran an identical strip 180 degrees around the barrel on the bottom side, just for symmetry, which may or may not be necessary.
This solution seems to have effectively stopped the zoom creep, without having any noticeable effect of the zoom action of the lens. The tape appears to provide just enough friction to stop the creep, but not enough to impair manual zooming. It offers several benefits over the rubber band solution, at about the same cost (next to nothing). First, it is virtually cosmetically invisible, (black on black). Second, there is nothing to get between your fingers and the lens, so it is functionally invisible as well. Third, it does not cover either the zoom or focusing numbers on the lens. I will be monitoring the black tape for signs of wear. If anyone sees any pitfalls with this solution, I would be happy to hear them.

Causes gnashing of teeth and rending of clothes and potty-mouth language.
In addition to black tape, I also have red, blue, white and green tape. These are used to mark phases. Not hard to guess what I do in my real life.
I will try it.

That would be my concern as well, but I would think the tape would show some signs of scoring beofre there was actually any transfer of of material that could get caught in the inner workings of the lens. I think the key is to watch the tape very closely for any visible signs of wear. If signs of wear develop, it is quick and inexpensive to replace the tape with a new strip.

One thing you guys better think about before you get too deep in Afro-engineering this thing is to consider that even good quality 3M electric tape has a tendency for the adhesive to bleed with age and heat. You will gum the works up and sell this lens to some poor sucker. Don't do it.

When you pull in conductors, they are often not marked with red, black, blue or white. Often they are all black. So you need to mark the ends as you pull them in.

This is a new and innovative feature that Nikon engineered into their "training" or "starter" lenses. This anti-chimping feature has been a great success in teaching photographers proper technique. Of course some people cheat and defeat the "anti-chimper" by putting a Live Strong rubber bracelet on the lens.

People are beginning to not care what you think proper technique is. Your anti-chimping crusade has taken on religious overtones. (Don't look at the LCD. It is holy. You are not worthy.)

I don't see what you have against the lens, which is clearly one of Nikon's great successes in the marketplace. I put my order in at Camera World a few weeks ago. I'm hoping it will be in before summer.

There's not one single lens that will cover that range well, even the 18-200 VR. You'll need the 17-35/2.8, 28-70/2.8, and 70-200mm VR lens if you want to cover that range.

I'm hoping it will be in before summer. Other than being of poor build quality, horrible light gathering properties, and overpriced for what you get, I really have nothing against it. I do like the idea that it gives you an 11x zoom range for general snaps when you have enough light. The dreaded "lens creep" and when zoomed to 200mm a FoV of a 135mm lens is what soured me to this lens. What's making this lens a success for Nikon is the over-hyping by Rockwell and others that have a vested interest. If you read the forums you will see most people use this lens as a stepping-stone till they figure out what good glass they want and sell the 18-200. I already sold my second one on eBay and I'm waiting for the third to arrive. Ritz is now getting them out in six weeks or less at $749.

Well, maybe if you feel you really must have f/2.8 at all times. I don't. I've often used 300mm lenses (or zooms at 300mm) wide open at f/5.5 or f/5.6 hand held on 35s and had no problem -- and much of that was back in the day, with relatively slow films. Admittedly I only used such lenses in good light, but I never really saw that as a serious limitation. Most of those subjects would not have been worth taking pictures of in poor light anyway.

Most of my Nikon lenses *are* DX since it's only in the last year or so I switched to Nikon dSLRs. And I'm delighted with them, so I'm afraid I have to take your "poor build quality" with a grain of salt.

Since I don't have the lens yet I can't comment on the "dreaded lens creep." If it creeps it creeps, but I've had that on one or two other long zooms and while I'd agree it can be mildly annoying I never found it a disastrous fault. Someone said his creeps only if it's partly zoomed to begin with, which is not how I'd ordinarily carry the lens on a camera. Well, we'll see.

At least I presume it is; Camera World and Ritz are essentially the same company so I'd guess CW gets 'em out just about as fast.

I've seen the sort of thing you're talking about with macro lenses. At least some 50 and 100mm macros shorten focal length substantially as they approach 1:1. I wasn't aware that IF zooms did the same.

I thought an internal focus design did not move the front element, which the 18-200mm VR clearly does. Or am I wrong about what an internal focus design is? The 70-200mm VR is what I think of when I think of internal focus.

however, zooming *does* change the length of the lens. it would be quite a feat to zoom from 18 to 200 without moving the front element and many of the others.

Lens creep is a quality control issue and shouldn't be tolerated with a lens in this price range, especially from Nikon. Just because a lot of people accept this as the norm doesn't make it right. Of course, Nikon will fix it for you if you send the lens back under warranty. Why, for Christ's sake doesn't Nikon catch and fix these problem lenses prior to them leaving the factory? It isn't like they don't know about the problem.

If you're speaking of close subjects then I think I can see how focal length of an internal-focusing lens is likely to (maybe required to) shorten at close-focusing distances, just as it does with many or most macro lenses. In any case if it's really at 200mm, it must have the FoV of a 200mm lens, not 135.

I compared this against the 70-200 VR, which I assume also *slightly* reduces focal length at close focus. At a distance of 8' the image of the test subject from the 18-200 was 35% smaller than that from the 70-200. I realistically and fairly expected it to be smaller, but this drastic was a real surprise. I guess it's a real non-issue for some since you can, in some cases, zoom with your feet or just crop in post. That said, the FoV of all 200mm lenses aren't going to be the same.

I also see no difference in FOV between the 70-200mm f/2.8 VR at 200mm and the 18-200mm VR lens, so where are you getting this 135mm stuff? The specs for both lenses on a DSLR are 8 degrees at 200mm. Or do I have a vested interest, too?

You are right, there is a big difference.
So tell me, at what point does the 200mm on the 18-200 equal the 200mm on the 70-200?

It's simply a case of buy low and sell high to the people who would appreciate this lens. It's a good lens for flipping to turn a few bucks with no effort. I only hope the hype continues.

Well, that's a heap of good replies, thanks to all.
The agents told this chap that it is not fixable, hence my query. I will pass on all posters' replies, at least it will settle his mind as to whether his lens is a one-off or not.
Thanks again,

babaloo - 20 Feb 2007 00:02 GMT Does anyone own any wide to tele zoom from any manufacturer that does not eventually exhibit zoom creep? Some lenses have a tab to lock the zoom while carrying it so the lens does not creep but I think that's about it . . .

However, this lens does sound like it is a lot more loose than most of them.
Mine does not do it.

When I encountered a lens zooming problem I resolved the problem by using a cloth type elastic band, the type cloth band tennis pros wear on their wrists as a wrist sweat band. It probably can be cheaply bought in most porting goods stores that sell tennis equipment.
I often thought the cloth elastic wrist band had a secondary use, in addition to preventing lens creep. It just might also act as dust filter and prevent dust from entering the lens as the lens is pumped from short to long and back again so many times as the lens is used. Of course I didn't know if it really did act as a dust filter, but I often thought that it did. I never had a "pump" lens that eventually gathered dust internally as they so often do.
