2026-06-21 Canon Battery Grip BG-E3

The Canon BG-E3 was released June 14^th, 2010 for Canon Digital EOS Rebel XT and XTi cameras (also known as 350D cameras). It provides the typical vertical shutter release as well as doubling the battery capacity of the camera. You can use the camera’s original battery and a second battery—in any state of charge—or a tray that can hold 6-AA batteries.

The AA battery tray is a fascinating sculpture of plastic and gold plated (looking) contacts. It is the first battery grip I have collected that has the AA-tray and doesn’t have the camera battery tray.

Looking inside the battery compartment you can see how detailed the original casting was. Taking the care to use a web instead of a solid casting, chrome plating the inside of the tripod screw and it looks like more gold plated contacts all contribute to the feeling some real care and expense was taken in this Canon product.

2026-03-14 - History and Evolution of the Kodak Logo

While working as a junior clerk at the Rochester Savings Bank, George Eastman first began commercial production of dry photographic plates in a rented loft of a building in Rochester, New York in April 1880. In the next few years, Eastman became very successful and expanded the company several times. His company started as the Eastman Dry Plate Company in 1881, later became the Eastman Dry Plate and Film Company in 1884, and soon after the Eastman Company in 1889. The last name change occurred in 1892, when the Eastman Kodak Company of New York was organized. The company has been called Eastman Kodak Company ever since. The word "Kodak" was first registered as a trademark in 1888. The letter “K” had been a favorite of Eastman’s, he is quoted as saying, "I devised the name myself. The letter 'K' had been a favorite with me; it seems a strong, incisive sort of letter. It became a question of trying out a great number of combinations of letters that made word...

2026-03-20-Manfrotto monopods

Sometimes collecting is a matter of persistence. The Manfrotto “GRUPPO” 434SSB monopod (shown top) showed up one day at my local thrift store. They had a price tag of $25 on it. I had bought the lower Manfrotto Compact MMC3-01 monopod at the same thrift store for $3. So I asked, “Why so much?” They answered their “expert” had found it sold for $200 on the internet. I find experts—who almost never clerk in the thrift store, so are unreachable—hard to deal with. There is also the matter someone might actually pay them $25 for a 2.27 kg (5 pound) aluminum pole, so I decided to let the Gods-of-Collecting decide if I was going to ever own it. For weeks I would pick it up, check the price tag to see if they had come to their senses, and return it to the shelf. I did try various clerks to see if they would lower the price, but they said they were not authorized to change prices. I plodded on, week after week without much hope. ...

2026-03-25 The Kiron 70-150 mm F/4

This Kiron 70-150 mm f/4 Macro1:4MC zoom was made by Kino Precision, Japan in 1980. The same company made both 1.5x and 2x extenders for this lens. It is a lovely design featuring a 52 mm filter size —common to many normal lenses—and a constant f/4 at all zoom positions. The f/stops are full stops from f/4 to f/5.6 and from f/16 to f/22 while the other apertures are half stops apart. FOCAL LENGTH RANGE: 70mm - 150mm [2.1X zoom ratio] DIAGONAL ANGLE OF VIEW: 34.3° @ 70mm - 16.4° @ 150mm LENS CONSTRUCTION: 13 elements in 9 groups WEIGHT (Olympus OM Mount): 460 g (with hood, front and rear caps) The macro range sets in below the three foot (0.9 m) marked distance at all zoom positions but you only get to the minimum 1:4 ratio at 150 mm. Macro starts around a 1:8 macro range at 70 mm. This is the only lens I have ever collected that has the original price sticker on the rear cap. At least I assume it is the original price sticker… It ha...
