Hi, my Director loves videoing with the 50mm f2.8 macro, but the aperture ring clicks keep ruining the shotgun mic recording. Does anyone have any resources/ links/ experience or advice about how to declick this lens? Or Sigma lenses in general? Thank you

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

Wed, 15 Apr 2026 21:50:02 -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.

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!

Canon EFS 18-55 IS Kit lens: Kit lens autofocus not focusing properly

Sat, 03 Jan 2026 17:44:49 -0700

Good afternoon everyone,

Today i present my trusty old 18-55 kit lens (F3.5-5.6) which has been gradually failing. I was teaching someone a bit about cameras and were trying to take photos and it just stopped. When holding the shutter button down half way, the lens focus ring barely moves if at all. This either requires me to manually focus my shots now or use my other non-IS lens (my 75-300 EF).

I use a 450D ancient camera and i have verified the aforementioned zoom lens works with AF perfectly, however not the kit lens.

I would assume my AF motor is toast however does anyone have any suggestions for fixing this apart from tearing it down (I'm going into this blind as there are no guides on ifixit for this seemingly common place lens).

Thu, 01 Jan 2026 15:40:25 -0700

Hello, Got a Canon pakkage with Canon EOS 600D camera and two lenses; a 50mm-0,45m/1,5ft and a Canon EF-S 18-55mm F3.5-5.6 IS II. The 50mm lens is working good, but the 18-55mm lens doesn't turn the camera on. The fisrt two times i tried this lens, it was working. After that it didn't anymore. Took out the simcard and batterypack and disconnected the lens. Put everything back in place and the camera was working for a small period of time. Now the camera doesn't turn on with the 18-55mm lens; camera still works good with 50mm lens. Do you have any suggestions? thank you, greetzzz, André
