If you are talking about taking the lens apart to clean the individual elements, unless you have the proper re-alignment equipment, you will never get the lens together correctly. And what's to prevent the same thing happening again? If humidity is a big problem, you should consider cameras and lenses that are sealed against moisture.

I have a Nikon AF-S 55-200mm 1:4-56ED. Focuses fine, lens goes in and out fine...except...it doesn't retract completely flush with the barrel of the lens. Is this a big problem?


I do not have that particular lens in my collection, but not all lenses do completely retract to a flush position. If your lens performs well at all focal lengths and takes sharp pictures, it is probably ok.

Hi, Everytime I zoom in or out my sigma lense 18-200, there something inside the lense that shakes. In the viewfinder, the image will shake everytime I zoom in or out the lense. It's a 2 months old...


There's nothing you can do to fix this yourself, it must be repaired professionally.

But as the lens is only two months old then it will be covered by Sigma's warranty so just send it to their service centre in your country for a free repair.

Note that if you live in the UK then you also have the right to return the item to the retailer for a full refund or an exchange under the terms of the Sale of Goods Act.

Please tell me the best lens and flash for D3100 i m not a proffessional photographer and i rarely go to see wild animals in forest. I want to click family photographs and natural beauty


hi there,

i used d3100 a few months ago,
for your information this camera only support autofocus with built-in motor lenses
if you have interest on wildlife, you should use tele-lens whose focal length above 200mm
if Nikon lenses cost you too much, you can choose other lenses from Tamron, Tokina, or Sigma

for family photograph, the kit lens is able to do this (18 - 55mm),
for natural beauty, i myself use nikkor 50mm/f 1,8 which has great power in low light condition

hope this will help

Best lens to add to d40 nikon to take baseball picture from dug out


So many people are browsing for the best D40 lens to take baseball picture i will give you some information about this topic i am not a professional photographer

if it's played on a full sized diamond you'll need 300mm if shooting from on the field/dugout. 200mm isn't long enough to shoot corner-to-corner. Realize though if it's not sunny at that time of day (i.e if it's overcast) you'll be shooting at 1600 to get needed shutter speeds at 5.6

IS is not necessary but USM is. THe 70-300 is the best choice for your needs as long as lighting is good.


hope this information will be help full for you

Gave a close look clean on my 55-200mm today. Received new Jul 14, 2010. Approx 1/4" from center, there is a small like 1/4" smear line. This is on the inside looking at front of lens. Line appearance...


It is usually not a good idea try to take apart a new camera lens by yourself - unless you're a professional. Better to take it to the dealership repair store and see if it really inside and if the lens has a warranty, try to get it replaced by the seller.

Lens unable to auto focus


try cleaning the lens.

Also set the focus range in the camera to average both vertically and horizontally. That is when you press the shutter button thos red squares in the look through a;; ;light up rather than just the centre square.

I suspect it is getting feedback from something on the lens that it reads and tries to focus on that is closer than the object you want to photograph. Make sure there is no mold growth inside lens as that will do it too


Please rate my help++++Thanks for using FIXYA

I dropped my lens and broke a plastic piece off the bayonet mount


Unfortunately, Nikon does not incorporate better built into the kit lens. If the break is merely cosmetics, my advice is to try to repair it or live with it. Most times, the repair cost may exceed the $100-$125 [used price] of the 55-200mm lens.

There is a tarnish to the eye of the lens Sigma Zoom 20-200mm


From your picture it is impossible to tell if the blemish is on the rear element or internal. The first thing I would do is clean the external lens surfaces then take some pictures. You may find that the blemish has no effect on picture quality. If that is the case, I would do nothing.

If it does affect your photographs, you will need to take it to a camera repair man. What ever you do, do not attempt to disassemble the lens yourself. You will not be able to get it back together and only add to the cost of repair. As far as cost, that is up to the camera repair man you choose. Without looking at the lens, he will not be able to give you an estimate. Check the cost of repair against the replacement value of the lens on E-bay and then make your decision.
