QWORK DSLR Camera Repair Tool Kit - 3/8" to 3-15/16" Lens Repair Set, Anti-Magnetic 3 Tips, 6 Screws & 2 Hexagon Wrenches for Canon, Nikon, Sony, Olympus Cameras

very nice .

I wasn't expecting a lot from this QWork tool for the small price, but it is superb. Don't let the price fool you. It is solid, heavy duty stainless steel, and very well machined and designed. The exchangeable multi tips also make it very versatile for use on any type of lens retaining ring. Even the tips are precision-made, hardened steel. I used this to rescue two Pentax lenses that had internal fungus, and was amazed that it was so solid and sturdy that I was able to unlock the factory-cemented retaining rings without using any solvent to dissolve the locking glue. This little $15 tool saved two $600 lenses. A best buy.

I needed this to work on various telescope adapters that have index marks on each side of a ring and it works fantastic for that purpose. It's adjustable width lets me adapt the tool to whatever diameter I need. The adapters often get stuck from compression and this tool easily removes them.

Gets the job done, but kinda "fumbly" to setup! Beetter than my old ones!

Surprisingly high quality for the price

I bought this tool to work on some cheap, flawed lenses I bought. It does the task, but I find myself desiring and needing a better tool. The thumb screws are always loosening up during use. The design is a little awkward to get good torque on a stubborn lens element. The pointy tips are 'too pointy'. If they slip out of one of the depressions in the lens element, they tend to gouge whatever they contact. I'm new to the lens repair thing, but I found myself on day one wishing for a better tool for the job. But, it did do about 80% of what I needed it for adequately well. For example the stepped flat blade tips work well. So worth having in a tool box.
