Over the past ~10 years, while working in several labs, I've had the opportunity to use everything from cheap toy-ish microscopes, to scanning electron microscopes, to laser-capture/confocal/fluorescent/top-of-the-line brightfield compound microscopes. I knew this scope would not be anything close to the ~$10,000-$25,000 scopes I've used at work, but I've been pleasantly surprised.
Viewing through the eyepieces provides a pretty good image. I've found this scope lacking for photography when hooked to my Canon 7D with an Omax adapter, but it's pretty solid for video with the exact same set up. (I mostly look at protozoa at home). The objectives are semi-plan (definitely worth stepping up from achromatic lenses....I hope to go to plan lenses in the future), and they do a great job, as long as you keep your subject roughly centered. The 100x objective (1000x or 1600x, depending on which eyepieces you use) does not provide the best images (for your eyes...I don't even try to take photos) on this scope, but that should be expected. The 4x, 10x, and 40x objectives work very well with the 10x and 16x eyepieces. I find myself using the 16x eyepieces more than the 10x.
My biggest complaint after one week is the iris on the field diaphragm. Its edges are rather ragged, and not at all what I'm accustomed to (again, probably due to the fact that I've been using 'nice' microscopes). The included blue filter is nice to have....it counteracts the yellow from the halogen bulb and makes the background appear white-ish. I do find myself wishing that the light could be brighter though (especially at higher mags).
The documentation included with the microscope was rather inadequate. It was fine for me, but I could see a beginner being a little lost. I was particularly surprised there was no mention at all of how to set up Kohler illumination on this scope.
