I HAVE A SCRATCH ON MY LENS, 35MM PLEASE HELP I WOULD LIKE TO BUY A REPAIR KIT.

It takes two CR2 batteries. See page 15 of this manual.

If you have more then one autofocus lens, is the problem limited to one lens only? if it turns out that the camera needs professional repair (and it may), keep in mind that an N6006 body is currently available on E-bay for $35 (buy it now price) and an N8008 is only $40 (buy it now).

Hi There,

Repairing a scratched is the hardest lens repair to accomplish successfully. It may be worth a shot to check with the manufacturer if ther is some kind of warranty or replacement program. The best option is to replace it. However the cost of replacing the lens may cost more than what the camera is worth. With that in mind, here are a few DIY options things you can try that may or may not work.

1. Scratch Repair Kit
Stuff Needed: Digital camera lens cleaning solution, microfiber cloth and a Scratch Repair kit.
Many companies sell scratch repair kits so there are several available on the market. Do your research to ensure it can work on, and is safe for your lens. Test it on an old camera if you have one lying around just to make the results are what you're looking for.
a. Clean the lens with the lens cleaning solution, and dry it off completely.
b. Follow the instructions provided with the kit.

2. Rubbing Alcohol
Stuff Needed: Digital camera lens cleaning solution, 3 microfiber cloths and a 3.5% solution of rubbing alcohol.
a. Clean the lens with the lens cleaning solution, and dry it off completely.
b. Dilute the rubbing alcohol by mixing 20 parts water to 1 part rubbing alcohol to get it to a 3.5% solution.
c. Take a brand new microfiber cloth, dip it in the diluted rubbing alcohol solution, and rub into the scratch using a very gentle motion.
d. You will know if this is working if you start seeing the scratch disappear.
e. Once the scratch has completely disappeared, take another brand new microfiber cloth and dry and buff the entire digital camera lens.

3. Vaseline Method
Stuff Needed: Digital camera lens cleaning solution, 2 microfiber cloths and Vaseline.
a. Clean the lens with the lens cleaning solution, and dry it off completely.
b. Dab some Vaseline on your finger and fill the entire scratch with it.
c. Using a new microfiber cloth wipe the Vaseline off very gently. Pressing too hard may cause the Vaseline to sink inside of the scratch.
d. You will know if this is working if you start seeing the scratch disappear.
e. As the Vaseline eventually rubs off, you may need to reapply some more and continue until the scratch disappears completely.

4.Pencil Eraser Method
Stuff Needed: Digital camera lens cleaning solution, 2 microfiber cloths and a new, soft pencil eraser.
a. Clean the lens with the lens cleaning solution,and dry it off completely.
b. Lighlty slide and rub the eraser unp and down along the length of teh scratch.
c. You will know if this is working if you start seeing the scratch disappear.
e. Continue rubbing the eraser until the scratch disappears completely.

NOTE: Never apply the lens cleaning solution directly to the lens itself. Alway dab a microfibre cloth with the solution then clean the lens and allow to dry.

Hope one of these works for you.

I believe you mean the focusing screen. While this is an interchangeable part on higher-end Nikon cameras, it's not on the N90s. Your local authorized Nikon repair center may be able to replace it, if they can get a spare.
Before repair, bear in mind that the focusing screen will not directly affect any of your pictures. Due to the very nature of a SLR, when you take a picture the mirror flips up next to the focusing screen to let the light from the lens through to the film, bypassing the focusing screen and the rest of the optical viewfinder system. If the scratch isn't very big then while annoying it won't affect camera operation. If the scratch is very large, on the other hand, it may affect the exposure metering and, of course, your viewing.

First, make absolutely sure that the electronic contact pins on the camera body and the lens are clean, grease free, and undamaged. Next, double check that you haven't simply left the focus selection switch set to manual focus.

If the fault is still present then you need to establish whether the fault lies with the camera body or with the lens. Does the fault occur with all lenses or just with one? If you only own one lens then you'll have to borrow another one to find out; if you visit a camera shop in order to do so then just pretend you're thinking of buying a lens and would like to try it on your camera (obviously you''ll need to have your camera with you). Don't tell them why you really want to try it out!

If it's with all lenses then you have a camera body fault. There is no way for you to repair a faulty AF sensor so will either have to live with it or send the camera for repair.

If the fault is with just one lens then the lens needs to be repaired or replaced. If the lens is a basic kit lens as supplied with the camera then it's usually better to consider either buying an upgraded lens or looking for a good used example of what you have (plenty of folks sell the original after an upgrade). Kit lenses are manufactured as cheaply as possible so repairs are usually not cost-effective unless the lens is covered by a warranty. As with the camera body, there is nothing you can do yourself to fix the lens.

If you need the camera or lens repaired and there is no warranty cover, then in many countries worldwide authorised Canon Service Centres offer fixed price repairs, but these prices only apply if there is no evidence of liquid damage nor of any unauthorised repair attempts and there are some other exceptions. Visit the Canon website in your country to find out more.

Good luck, and I hope that you soon have functional AF again. Please take a moment to rate my reply.

That's a question only you can answer. Both are fine lenses. What kind of photography do you want to do? The 50mm is generally better for portraits, while the 35mm will be better for landscapes. Neither is very good for sports or wildlife.

You need to track down a 2x teleconverter that has a Pentax A mount for it to work correctly on the moun t of your camera.

I believe Adorama has one here:

Check with them first to ensure compatibility

Try your EOS in AV (aprature value) mode. You should be able to adjust your aperature value in 1/3 or 1/2 steps dependind how you have your Custom Functions set in your camera's menu. Possibly the lens you purchased is for an EOS 35mm. If you use a 35mm lens on your eos there are some calculations you must use. When using a 35mm lens on the EOS 20D, 30D, 40D and 50D bodies, you must first calculate your focal leingth by 1.6 times. With this, your exposure changes as well.

The only EOS Digital SLR bodies that use a 35mm x 24mm CMOS sensor are the 1D and 5D. My wife uses a Tamron 18-200mm f3.5-5.6 lens on her 20D and loves it.

If this makes no difference, you may have a defective lens.

Please do not open your DVD player, unless you know what you are doing. Best thing for you to do is buy a CD/DVD lens cleaner kit available at most Audio video shops and Radio Shack. It consists of a Disc to which a small brush is attached. Place the disc in the tray, and just follow the instructions given in the CD packaging. You should not - at ANY COST - touch the lens, or use things like cotton buds, or use any solutions. You could scratch the lens, or cause misalignment.
