See this earlier post.
I have not taken a huge amount of photos with my Chinese brand microscope during the time I owned it. Therefore a comparison is hard to make. I recently encountered the same algae (Asparagopsis taxiformis - Falkenbergia Stage / Sporophyte Stage) than I had in one of my first reef aquariums, so this presented a good test case to see just how much you get for the additional cost of a research grade microscope.
All the old photos were taken with a $500 Chinese brand microscope coupled with a $400 2.1MP Motic CCD. All new photos were taken with an Olympus BX53 microscope with UPlanSApo objectives and a Canon 600D camera. The old photos used bright field illumination, the new photos used DIC.Chinese microscope Research microscope Chinese microscope Research microscope Chinese microscope Research microscope Chinese microscope Research microscope Chinese microscope Research microscope
It is again clear that there is a vast difference in quality. The Chinese microscope allowed me to identify the algae / diatom, that much is true, but as a tool for creating photographic art it is not.
