Fixing a Stuck Zoom Mechanism on a Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens

Filed under: Uncategorized — admin @ 4:22 pm

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 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.

Fixing a Janome 1110DX Serger

Recently, a local friend from previous repairs brought over a Janome Serger that wasn’t working. The symptoms in this case were that the unit was completely “stuck” in that the manual handwheel could only be turned a few degrees, and the motor would not cause a significant rotation.
