Quick fix: Nikon AF-D 50mm f/1.8 lens shows a F33 issue, what now?

The nifty-fifty, as it’s often called by photographers, is a great and versatile lens. Yes, it’s a prime lens, meaning you can’t zoom in on your subject. But the beautiful bokeh-effect the 1.8 aperture causes, let’s you forget about that.

If you don’t own a 50mm yet, I can highly recommend it. I use it for all my portraits and most of the event-photography I am involved in. They are pretty cheap and a lot of fun. Most online stores sell them.

Though, recently I had a problem with this lens. It didn’t let me take a picture. I just upgraded to the Nikon D850, so I was sure this was causing the problem. My camera gave an F33 issue.

After receiving the same issue on my older camera, I started researching online to find a solution. All I found was loads of other people having the same problem, but no-one seemed to really find an answer.

By trial and error, I can now say there are two possible causes. Both are easily fixed. So fear not!

Solution 1: Removing cleaning residue.

I had a new camera. The connection part between the body and the lenses are cleaned in the factory. Sometimes it’s possible there is still some product left on the connection part. Carefully clean your lens and body. If you’re not comfortable with this, you can ask your local photography-business to help you with it.

An easy solution for a headache problem, right?

Solution 2: Your aperture is all wrong!

I kept having the problem, so I knew it wasn’t about the residue. Another possible cause is the manual aperture has changed. On the Nikon AF-D 50mm f/1.8, you can find a physical aperture ring. Sometimes it shifts. This shift is actually causing the problem.

Correct this by changing the ring back to f22. Once you do this, the camera can take control over the aperture again. Now the F33 error should disappear. You can take photo’s again, and change the aperture on your camera.

Have you encountered this problem too? What solution worked for you? Let me know in the comments!
