Mitutoyo QV Quick Vision Measuring Machine Teardown

Robert OToole ·

After 2 years of sitting in my garage gathering dust, my QV scope finally made it into my office to begin the teardown process. The original owner had lost the software keys to use the scope so it was sold for parts only and that means I would not be able to use in the factory configuration. This is the most complex scope I’ve ever handled so the goal of the teardown is to see what parts I can use for photomacrography. The scope has a total of 6 fiber optic lights and all movements are powered, XYZ, even the objective zoom and ring light are all powered. It’s a massive unit and surprisingly heavy.

Let me know if you are interested in anything from the scope, the objective has already been sold to offset the cost of the scope.

Any questions or comments, send me an email.

How to save A Macro Lens From the Trash Bin

Robert OToole ·

Componon 4/28 before and after a quick repair.

Luckily I happened to come across this gem of a lens just in time to save it from being tossed into the trash bin! Instead of throwing this defective lens in the garbage, the owner was nice enough to send me the lens on the chance that I might be able to fix it, and give it a new home, and of course I was happy to help.

With the rear cell removed we can get a better look at the iris, you can see the blades that have slipped out of position but don’t appear to be damaged.

To access the iris mechanism, I removed rear and front cells, this lens had particularly tight cells that were not easy to loosen.

The problem? A few iris blades managed to slip out of their guides. Luckily none of the iris blades were damaged in the process.

Nudging the pins back into the guides was easy with a pair of needle nose pliers. Love the nearly circular 15 blade iris. The iris lever is located at 1600, and the ball bearing used for aperture detent clicks, at 11:30.

Componon 4/28 back in perfect working shape

The Componon back in perfect working shape. The older Componons are really well put together, and this particular lens is in excellent condition despite being produced in 1963. All of the 4/28 Componons types are really good performers, and these old lenses are perfectly capable of making excellent images.

The Componon 4/28 installed on my A6300 52mm/SM2 Studio setup.

The 4/28 lens is attached in reverse using a M 30.5 to M 52 step-up ring from eBay. Normally I keep a lens snoot made out of flocking paper on the rear of the lens when shooting, but it was removed it for the photo.
