8 MP Camera 4-Zone 144-LED Stereo Microscope 3.5x-90x

This is a turnkey package of trinocular LED stereo microscope with 8.0MP USB2.0 digital camera. It comes with a trinocular 3.5X-90X stereo zoom microscope, a contemporary table stand and a variable 144-LED illuminator with dimmer. With 30mm super widefield eyepieces and reduction objective lens, the microscope offers super widefield optics, very large zoom magnification power (26:1), and large working distance (8", 200mm). The variable 144-LED ring light is lighting-direction changeable and lighting-intensity adjustable, providing cool, even and bright LED illumination. It comes with a specially designed control box allowing you to turn on/off each portion of the light ring separately and change the lighting direction for obtaining best microscope stereo images. The color digital camera captures 8.0 Megapixel high resolution microscope images and streams live video on your PC screen. Its built-in reduction lens gives your computer screen the same field of view images as those seen through the microscope eyepieces. With the included user-friendly software, which is compatible with Windows XP/Vista/7, you can edit microscope images in a manner similar to PhotoShop. You can conduct measurements across images, record videos, share images, and save them in BMP, TIFF, JPG, PICT, PTL and other formats. You can measure lengths, angles, areas and etc. This microscopy system is an ideal instrument for gemologists, manufacturing engineers, and anyone in semiconductor and electronic industries. It is also the right microscope for biological laboratory applications that require low heat release. It is made by the same technicians and on the same production line that makes optical instruments for Leica, Zeiss, Nikon and Olympus. This microscope is brand new in factory sealed boxes. The retail value of this microscope is $2,900.

This could be the answer to all of my prayers...for now. Panasonic Lumix G2 Micro 4/3 Mount camera with a Leica DG Macro-Elmarit 45mm f/2.8 lens and a Panasonic Lumix GH2 Micro 4/3 Mount camera with a Voigtlander Nokton 25mm f/0.95 4/3 Mount (manual focus) lens. I am of the opinion that these cameras have taken off in popularity because of the niche that they fit. They offer former Leica M shooters the ability to mount M-mount lenses on a cheaper body. Now that Panasonic has paid so much attention to developing high quality, auto-focus lenses, at a much more attractive price point than Leica M lenses, I see these bodies as really fulfilling a desire that has yet to be met by the market. Add the collaboration lenses like the Leica DG Macro-Elmarit, and third party 4/3 mount manual-focus lenses of extremely high quality like the Voigtlander Nokton, and I am of the opinion that herds of former Leica shooters will come running back to this type of capability (after converting to DSLRs), which is quite different from DSLRs - as different as traditional film rangefinders were from film SLRs. Whether there will be a confluence between the Panasonic and Olympus communities remains to be seen, as does the direction Panasonic goes with these bodies pictured above. I hope they continue to evolve into professional bodies (at least the GH2) to feed the niche I have just described, while letting the GF series of bodies remain more consumer oriented. In the end, I have never liked the distinction of "professional" vs. "consumer" since there are people who take amazing photos with what are regarded as "consumer" cameras, however, my careful use of the terms relates more to capabilities and options than anything else. I settled on the G1 in the beginning because I like to look through a viewfinder most of the time and I was attracted by the size and quality of the 4/3 lenses. I upgraded to the G2 simply because it is a better camera and has video. I got the GH2 because of the new sensor and its greater capabilities in low light. Now with the expansion of the family of lenses I am hooked. Whereas I became quite accustomed to reaching for a beast like the 1D Mark IV and its heavy glass, I now find myself reaching more and more for one of these bodies. Enough so that the days of the 1D in my arsenal may be numbered. I fully understand they are different weapons systems if you will, but whereas I often think about the bulk and weight of the 1D's and glass when I am out shooting, I never do when using one of these; and that is becoming more of an important issue now that I shoot mostly street shots.

I hate when people get too introspective or downright geeky over these things so I will end this little diatribe by simply stating that I have shot with one type of G body or another since the G1 came out, and I have not been disappointed. I will retain at least one DSLR, the Canon EOS 60D, since that allows me to better capture the quirky movements of my 3 year old. The DSLR is also generally better for low light because of the bigger sensor, but I think the majority of my shooting will be with the G2 or GH2 since it is, well, fun!

1000mm Mirror Lens Photo 4

1000mm Mirror Lens Photo 4

500mm F/8 Tokina OM-mount mirror lens fitted to my Olympus E-500 via a 4/3 adapter. The digital camera's sensor size delivers a doubled magnification with this vintage lens to what would be a 1000mm (20X) lens in film days. Fun. But . . .

Mirror lenses, especially inexpensive ones like this one, were known for being "fuzzy" and provided doughnut bokeh. I went with that. Thanks to PhotoShop for sharpening and a healthy dose of noise to boost apparent sharpness.

Still, shooting in very close quarters with a 20-power lens makes for a lot of breath-holding while releasing the shutter. I only had a monopod with me, should have used a tripod. Still, quite a lot of fun for a bright Sunday morning walk in a flower garden.

Shooting distances were all around 5-10 meters.
