2026-05-27 Rollei F19BC Flash

There were two Rollei flash that looked pretty much the same (see below). This is the more recently collected F19BC. It takes 4-AA batteries, has the standard locking PC cable attachment, as well as a standard hotshoe connection. It has one auto setting for use at 3.5 m / 12 feet and less. At ASA 12 / DIN 12 the auto setting would be f/2.8. At 100 ASA / 21 DIN the auto f/stop would be f/8. At the far end of the calculator using 1600 ASA / DIN 34 film, the auto f/stop is well below f/22 (maybe f/32-f/64).

Rollei has a curious switch that—

locks and slides to unlock the PC cable
when slid it fires the flash manually

   These flash have a captive battery door that slides a bit to unlock and then flips open.
   Of note is the depth of the auto cell’s mount. The cell has tunnel vision of the field in front of it! The cell cover—that closed results in having a manual flash—has several small detents but the flash should have the cover either entirely open or entirely closed.
   On Rollei 35 cameras these flash are mounted on the bottom of the camera and the flash reflector is reasonably centered below the lens. This results in unnatural looking images as the shadows cast by the flash angle up instead of down. I suspect Rollei 35 users take flash photographs with the camera held upside down.

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...

2026-06-23 Olympus Camedia D-535 Digital Camera

The Olympus Camedia D-535 digital camera is a cute little camera, introduced September 16, 2004. It was modestly priced at about $175 list. It had the motto, “one button/one function.” There were four scene modes available, as well as movies (QuickTime / 320x240 at 15 fps for as long as the memory held out) and “Program-Auto” on the rotary dial. A four direction with a center “OK” allowed rapid access to (starting at 12 and going clockwise)— EV adjustments plus and minus 2EV in ½ EV steps Macro (including Super-Macro allowing shooting down to 2 cm (0.79”) Reset Self-timer (12 seconds) The three buttons under the 1.5 inch (130,000 dot) screen (from left) are delete, menu access and flash modes. The two buttons to the right of the screen are camera (top) and playback. There is a rocker switch for zooming that doubles as a magnification /file views switch on playback. The power-on button is inset into the top at the middle of the camera, with the shutter button ...

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. ...
