    The Regula Cita III is a fixed lens rangefinder camera based on the Regula IIId. It is in essence a fixed lens Regula IIId. There are three versions of this camera, the difference between them is the lens used, either a Steinheil Cassar 45mm f/2.8, Zeiss Tessar 50mm f/2.8 or the rarer Enna Ennalyt 45mm f/1.9. It has the same light meter, rangefinder and shutter, though it lacks the f/22 setting of the IIId. The viewfinder in the Cita III is the same as the IIId with a small circular focus spot and no frame markings.

The rangefinder control is similar to the previous generation Cita camera where the focus ring is mounted behind everything next to the camera body. This makes using it quite awkward as at either end of the focus scale (1m or inf.) your fingers tend to block either the viewfinder or rangefinder windows.
    

    The camera has a light meter made by Gossen and it reads using the EV System The light meter has a flap covering it (missing on this camera), in bright daylight situations you keep the flap closed and take a reading, when using inside or darker condition open the flap. The meter dial can be a little confusing to read, when the flap is up use the orange numbers on the meter (the metal flap has a little orange notch on it when open to remind you presumably), when it is down use the white numbers on the dial. On the aperture ring there are red numbers from 2-18 (these are EV values), take your number reading from the light meter and line up the red arrow with the red number using the meter reading, this will give you the exposure required for the shot. When the value is set it limits you to a particular set of shutter speeds/apertures that correspond to that EV value, this lets you adjust for depth of field without affecting the exposure of the shot.

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.         ...

2026-06-23 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 ...
