Nikon Lens: My lens won't go past .7 meters of focus

Tue, 16 Jun 2026 07:57:22 -0700

So I got a used camera and a lens, but when it arrived, and I tried testing it out, it didn't function properly. I tried to autofocus for a landscape picture and I heard a clicking noise, and it wouldn't go up from .7 meters. I thought it might be that the auto focus was broken, but when I tried manual, it was the same result. The little dial for the focus would turn after that .7 mark, but both the focus and the meter on top wouldn't change. I will attach a few pictures of the lens and the model of the lens. There will also be an image of the little bar and where it's stuck on.

Canon EF 70-200mm F2.8 L IS USM: Optical Element Alignment After Disassembly

Mon, 15 Jun 2026 08:55:08 -0700

I have a Canon EF 70-200 2.8L IS USM. The MF ring doesn't work but the AF works most of the time. Sometimes the AF seems to "get lost" and doesn't want to focus, but will eventually start working again. My guess is that the encoder disk is dirty or scratched, affecting the AF. The MF ring is probably slipping. I am thinking about taking the lens apart in an attempt to see what's going on. What is holding me back is that I have read that the optical elements must be realigned following any disassembly and it is not exactly DIY friendly. I am interested in opinions from people who have done similar disassembly/repairs like this, and what their outcomes were.

Canon EF-S 18-55mm F3.5-5.6 IS II: My lens has problems with the AF

Sat, 23 May 2026 13:55:11 -0700

I bought the camera with a used lens, and when I try to use the AF, it always gets "stuck" and if the focus is very close, it doesn't move at all (when it's open, it closes and then gets stuck), I have also noticed that the zoom movement is not as smooth as it should be (mainly when I am at 22mm), it gets slightly stuck and then works normally. I have already tried other lenses and the AF with my body (Canon T5) works perfectly. Is it feasible to try to repair it?

Nikon Lens: Nikon 14-24 mm AF-S f2,8 focus issue

Fri, 10 Apr 2026 02:10:47 -0700

Hi!

I have an issue with my 14-24 mm AF-S f2,8 lens.

Primary Symptoms:

AF Stall/Slip: When activating autofocus, the SWM attempts to engage, resulting in a slight "twitch" of the focus ring, but the internal elements fail to move. The camera eventually times out.
Mechanical Manual Override: Holding the focus ring or manually rotating it during the AF attempt temporarily restores functionality, suggesting a loss of friction in the internal coupling.
Tactile Play: There is a noticeable "gap" or loss of resistance at specific points during manual rotation of the focus ring, indicating potential wear in the friction clutch or helicoid tolerances.

When I hold the focus ring it obviously cannot AF stall or slip, and then the AF focus works perfectly. But it feels totally wrong to hold the focusing ring, especially because I never have to do that with any other lens that I own (plenty of them AF-S, primes, zooms, you name it).

What can be the reason for this? If I attempt disassembly, what should I focus on? Could it be the focus brush that needs to be replaced or cared for? Or is this a symptom of how the focus motor is dying?

Thanks in advance!

Good afternoon, I'm having trouble cleaning the first set of lenses from fungus. I can't separate the two elements of the first set of lenses for the Nikon AF ED Zoom 80-200 2.8 made in Japan. What kind of glue do you use? If any, what solvent can I use? Can it be done with heat? At what temperature? Help!
