Ah well, you should have told us you collect microscopes! I now use a
stereo zoom microscope, and it is very useful, although I still do
most assembly under a 4.5 inch diameter 3 x lens. I did however, make
a batch of ultra-micro animal tracking beacons under the microscope.
As another poster pointed out, the eye-microscope-brain-hand feedback
loop sorts it all out for you without even thinking about it. Even at
the max 20 x I have no problems with unsteady hands, although about
10 x is more use.

Every week or two, I put a piece of silk over the end of the vacuum
nozzle and do a "workshop sweep" in the places where the dropped SMDs
tend to gather. I usually get a few, plus some other useful thingies.
Of course, sorting them out often takes more time than it's worth.
