Question about Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens

1 Answer

Nikkor Lens Fix

I'm fairly new to photography. I recently took pictures that turned out sunlit and faded. I believe I might have scratched my lens. Is there a way to safely clean it without causing additional scratching. If it is scratched is there a way to replace it, or is it done for?

The fading (flare) you see could simply be a finger smudge or other stuff. One little scratch won't do it, you'd have to take sandpaper to the lens to see obvious flare.

It's actually harder to scratch a modern lens than most people think. When it happens, it's usually during cleaning when a tiny piece of grit is on the surface and gets rubbed in by the cleaning cloth/lens tissue.

So the first step in cleaning a lens surface is to be sure you remove all dust and dirt without rubbing. The lens cleaning kit you can find in any camera store is a start -- it contains a blower brush. With the lens surface to be cleaned facing down (so dust falls away), brush gently with the tips of the bristles to dislodge stuff. Then use the blower to blow it away. Repeat as needed.

If you still see dust and dirt which seems to be stuck on the surface, take a piece of the lens tissue from the kit and put several drops of the cleaning solution on it, enough to get it pretty damp. (Always apply cleaning solution to the tissue or cloth, never drop directly on the lens surface.) Cover the lens surface with the damp tissue, pressing it into the corners, but do not slide the tissue across the surface. Just lift it away. Repeat with another section of tissue.

Then take a full sheet, wad it lightly, and wet it. You are going to rub lightly, using a roll-up motion as you move the tissue so that dust/dirt is lifted away from the surface and fresh tissue is always coming in contact with the surface. Repeat as needed until there isn't any visible stuff.

Final cleaning can be done with a fresh piece of tissue and a bit of mist from your breath. Mist the surface, and lightly polish with the tissue to remove any remaining cleaner residue.

Hello, I own a Quantaray 28-90 MM zoom Macro lens. I would like to know its equivalent Nikon lens, which would be one of the following: 1) D or G type Nikkor 2) CPU Nikkor lens other than D...


This Quantaray lens is similar to a Nikon D-type lens in that it has an aperture ring. However, Nikon D- and G-type lenses communicate subject distance information to the camera using a proprietary protocol. Third-party manufacturers have to reverse-engineer the protocol, and they don't always get it right.

What this means for non-flash photography is that this lens works fine, with only minor exposure differences since Nikon's Matrix metering uses the subject distance information.

For flash photography, subject distance information is critical. My advice is to try it as D-type lens and look at the results. If they look good, fine. If they don't, try it as a non-D- and non-G-type lens (the second choice in your list).

The above assumes you have the Nkon-mount version of the Quantaray lens.

Could you confirm that this is a G lens (without an aperture ring)? If so, try cleaning the electrical contacts on the back of the lens and in the lens mount on the camera.

You can get the part directly from Nikon, and the repair is fairly simple. Look at the step-by-step of the same repair done on this page:

Nikkor Lens Cannot Manual Focus


It sounds like you had the lens set for manual focus when you took the A / M switch plate off. If this was the case then when you but it back together the little arm behind the plate is on the wrong side of a moving gear assembly.

To fix, remove the auto/manual focus switch plate from the camera (just the one screw not the ribbon beneath) Push the switch over to A. Hook the bottom of the plate back to the lens and put the screw back in. Done!

Camera will not take picture with nikkor 105mm lens


Check if the lens is properly mounted. If still you get the error message, clean the electrical contacts between the lens and the camera using an eraser. Take care not to let any dust fall into the body. Attach the lens and try.

Aperature ring


Hi, Is the aperture in max or min ?
Remove the lens. Try pushing the stop down lever and look through the lens if the aperture changes.
Look at this pic if you wonder what stop down lever means. http://www.mir.com.my/rb/photography/hardwares/nikonfmount/20AI-S2_8rearconv.JPG

Putting it back together


In 1965 I did the same thing with a Nikon single focal length lens my F Photomic. This lens was far more simple then a modern AF zoom lens. I had to bite the bullet and pay a camera repair man to fix the lens. He told me that had I not tried to fix the lens myself, the repair would have cost 1/4. The only answer to your question is to take it to a camera repair man and get a quote. I would check the quote against the price of your lens on E-bay and use that to determine if you want to fix your lens or replace it.

By the way, it is very rare for dirt between elements to be so problematic that it results in a degradation of picture quality.
