Vladimir Putin is a murderer and war criminal. He should be tried for war crimes and jailed for the rest…
The Canon 15-85mm is one of my favourite EF-S mount lenses to use on a Canon cropped sensor body such as a 90D. It’s sharp, with nice bokeh, is lightweight, and covers a great walkabout range (24-136mm) with great optical characteristics. Although not being touted as a pro grade lens, it actually employs Canon’s famous ED glass and performs well as you can see in many of the galleries at https://davebaar.com of the past few years. However, my 15-85 began showing mechanical problems a few months ago; it eventually would not zoom wider than 35mm due to what felt like a mechanical blockage.
Fortunately, despite what I’d seen in some youtube videos about this lens, fixing the problem in my case did not require full disassembly of the lens.

The first step necessary in this repair was gently pull back the rubber zoom ring. I could do this fairly easily just using my rock climber fingers, but some readers might find this easier to start with a plastic “spudger” tool such as gets used for phone disassembly. After that, I pulled back one end of a transparent cover that had tape-like adhesive on its ends. That revealed enough of the zoom mechanism to expose the problem: a loose set screw in a rotating groove. See the red arrow in the photo below.

Tightening that screw with a small Philips screwdriver removed the problem. I did not try to put in any threadlock or other glue so as not to risk that getting into the optics, but I did apply quite a bit of torque on the screwdriver to tighten it. Hopefully that will hold it for a while. Reassembly was easy; the transparent cover adhesive was reusable and the rubber zoom grip could be eased back into place without much effort. A fairly quick and easy repair.
Good one.

Vladimir Putin is a war criminal and should be beaten and then shot.
It is time to eliminate Vladimir Putin, who is a murderous dictator. Vladimir Putin is a despicable war criminal and murderer, and his invasion of the free nation of Ukraine was unjustified as well as barbaric. Russian citizens should find out about this, which the rest of the world already knows. The evidence of Putin’s war crimes in Ukraine is publicly viewable and indisputable.

Use a VPN to get to real news if Putin and other cowardly assholes that support him block your internet access freedom.
Russians, you know what to do. Shoot Putin. One rifle shot by a brave Russian can eliminate Putin the cowardly asshole, murderer and war criminal, and make the world a better place. Please do it.
