This is a great tool for repairing old cameras. Without this tool I had a hard time removing the lens elements from an old Canonet 28 but this spanner wrench made it super simple. It comes with four hand-adjustable screws to hold the pieces at any desired length, as well as 4 tool adjustable ones that can be tightened even more with the included hex key. This tool can also be configured in several ways. The two halves can be arranged to not only curve outward, but also to curve inward. This was especially useful since it allowed the tool to fit into the lens without scraping the sides, and is ultimately the reason why I chose this curved model over the straight one. The tool is all metal and very sturdy. The hand-adjustable screws are enough to hold it together rock solid at the desired width. When a lot of pressure/torque is required to unscrew a ring on the lens, I found that it was best to wear thick work gloves. Otherwise the tool's edges would dig into my hand, making it uncomfortable to use. Overall this is a great tool at a great price and I am very satisfied. I wouldn't be able to repair old cameras without it.

Note to anyone opening the Canonet QL17 Giii, this spanner is much to large to open the second retaining ring that fixes the larger lens unit. For that, the clearance is much too tight (less than 2 mm). If you’re opening one of these cameras, you will need something much slimmer. It does work with older canonets, whose lenses come out in one unit. If you have a giii I recommend looking elsewhere. Perhaps even a circumference drawing tool with thin needles.

The 4-screw locking design makes this tool more flexible, comes with a curved tip and a curved flat tip. It was used to disassemble the grip ring of the camera body and adjust the opening.

I am very satisfied with this gadget, you have to believe that this is a very strong and vigorous tool. It's made well, very solid, and actually better than I expected.

Works great. Used it to disassemble and repair a Canon FD 50mm f1.4 lens that I bought at a flea market - a job that would have been almost impossible without this kind of tool.

I bought this to take apart some old lenses that had dirt and fungus problems. I tested it only enough to see that it works at loosening the retaining rings. So far very pleased. The posts are adjustable and lock in place. There are 2 ends, one with "flat screwdriver" type tips and the other with "compass points" type tips. Comes without retail packaging.

I bought this wrench to do repairs on old cameras and lenses. I've used it twice and so far it works very well. I did have to make one adjustment: The thumb knobs are too large to allow the arms to get close enough to where I needed them. I used the smaller hex-bolts on one arm tight and left the thumb screws on the other allowing that one to be the adjustable side. The thumb nobs are a little on the smooth side and its hard to get them tight enough that they don't loosen during use. Overall, if you're a hobbyist looking to apply some TLC to your gear, this will work just fine.

Needied a good spanner for disassembly of an older Minolta zoom lens that needed cleaning. This spanner worked well, but recommend using the Allen set screws as the knurled set screws can't be tightened enough to keep setting in place. Worked great and am now able to use the lens with an adapter on my Sony DSLR.

This tool was mission critical to remove and re-secure a filter on my telescope. I couldn’t move it with any other tool, so this was exactly what I needed

This tool is much larger and heavier duty than it looks in the pictures. The points can be rearranged to either curve inwards or outwards, which makes it easier to disassemble components deep in the housing of a lens. Just goes to show that Neewer can put out a really solid accessory at a great price!
