QWORK Camera Lens Repairing Tool Kit, DSLR Camera Tool Set, 3/8" to 3-15/16" Lens Repair Set, Anti-Magnetic 3 Tips, 6 Screws and 2 Hexagon Wrench Compatible with Canon Nikon Sony Olympus Camera

I dropped a lens and in order to repair it the front element had to be removed. I learned that the two tiny holes 180 degrees apart on the front of the lens mounting ring, required a lens spanner wrench. I ordered this kit, and in 45 minutes I had fixed my lens. The tool is all metal, and comes with three pairs of tips to engage the lens. The tool is held together with 6 thumbscrews, four for the sliding bars and two for the tips. In the event that more turning force is required, they include 4 Allen head screws and the Allen wrenches. That's a nice touch. Needless to say I'm pretty happy with the tools and the luck I had fixing my lens. Now, I'm going to tell my wife that with the $350 I saved by fixing it myself I'm going to spend that on another camera accessory!

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!
