Despite being a fan of stereo photographs, and having tried a few stereo (binocular) microscopes for PCB work, I've never been a fan of them. I've always preferred head-mounted visors, since they are in exactly the right place/angle, have a good image, and don't interfere with the soldering iron etc. With that in mind, I stumbled across four microscopes, and picked them up with the intention of flogging them. Unfortunately they are much better than I expected, so I've got to revise my opinion.
What do I like about them?
excellent image, easily fused into a stereo view
good clearance, ~70mm, sufficient to allow an iron to reach a PCB
4mm/8mm diameter field of view (*25/*12)
usable depth of field, not much adjustment required for top/bottom of an 0603 capacitor or an SOT23 gate
higher magnification than the visors (~*12 and ~*25); not necessary for soldering, but much better for inspection
Despite that, I'll continue to use my visor for soldering and peering into the depths of faulty equipment.
Does anyone know a good way of taking photos (not stereo!)? The pictures below don't do it justice, since they were taken with a not-very-good phone camera held in place by hand.
Does anyone know the key differences between Beck Binomax 15001/15324/14933/15046 microscopes; googling doesn't seem to produce any useful results, so I guess the numbers are simply serial numbers.
Ditto prices, since fleabay is similarly uninformative.

Hi
Both visors and microscopes have their place in the lab. Illuminated magnifiers are something else I would add to that list.
There are an enormous number of USB microscope cameras out there. Some microscopes have a third axis on them for pictures. On others you replace an eyepiece with the camera and mount. Each has constraints in terms of optics you need between the camera and the microscope. It's no different than picking the eyepiece you look through. eBay and other online venues have a lot of them to pick between. Matching one up properly to your microscope involves a bit of work.
One thing to consider with a camera:
The amount of light that works for normal viewing may not be enough for some camera setups. You may need to upgrade the illumination when you put on a camera.
