Nikon 50mm f/1.8D disassembly
Apr 7, 2013

My lens fell on the ground and the focus got stuck. 
Did anyone disassemble this lense yet?
If I disassemble it from behind I can't get to the focus ring, only aperture ring comes off, so I would have to disassemble it from the front but I don't know how because there aren't any screws there.

If you can aford Nikon 80-200mm f2.8 and Sigma 70-200mm f2.8 than you can just get another 50 if you need it you will not fix this lens by yourself. This time get best f1.8 one that was made in Japan. It will cost you $85-105 of eBay.

Previous poster is correct.  Not worth fooling with or fixing; just buy another 50.

If you want to try an hour or so taking it apart with reasonable skill and good quality screwdrivers it should not be difficult.

You might find there are screws under the focus ring rubber that need attention.

Whether you can straighten the bent ring and if anything else is damaged is something you might find out.

Making careful notes of exactly how each part was positioned before taken the lens apart can help put it back together with every part exactly where it should be.

Producing good quality photographs, or being good at sport or art, involves a little more than buying appropriate equipment. Practice, some learning and perhaps natural talent often play a bigger role than the equipment in your hands.

I took mine apart last year to get oil off the aperture blades, but while putting it back together introduced a weird focus offset that makes it impossible to turn it to infinity (i.e., the ring gets stuck just before). Let me know if you take it apart and encounter the same problem.

This lens is worth less than $100 new so it is a good excuse to get a new AF-S 50 f1.8 lens. My 50 f1.8D is gathering dust somewhere in the cupboard. I also have a AF-S 50 f/1.4 and an old 50 f/1.8 Nikkor manual focus lens on my film day.

Take a look at this video, it should tell you something

Good luck
