2026-06-02 Olympus 75-150mm f/4 Zoom

The Olympus 75-150 mm f/4 zoom lens was introduced in 1974. It was stated that this lens worked at least as well as single focal length optics. It is a two-touch lens, has as most Olympus lenses a stop-down button on the mount, weighs 452 g (1 pound), is 115 mm (4.5”) long and is 63 mm (2.5”) in diameter. It has 15 elements in 11 groups. It has an eight-bladed iris.

It can focus as close as 1.674 m (5.5 ft). While this has been severely criticized as “not close enough” try dividing those figures by three (150mm / 50mm = 3) and you get .558 m / 21 inches. The normal close focus of a Nikon standard lens is .4 m or 15.74”, so the Olympus zoom isn’t that far off. Besides the zoom takes 49mm filters so you can use a set of three close-up filters—+1, +2, +3— and work much tighter to the subject

The zoom has a built-in lens hood. This is again purported to not do that great a job, but I disagree again.

Anything that—

is always with you and
cuts down all light falling on the sides of the front element

is doing you a great favour.

The fact a light source in the frame causes veiling (aka loss of contrast) and spurious reflections has a lot to do with the single or at most double coating used at the time. Of course later optics did better, but for any subject you shoot with the sun behind you—or even beside you—as long as there isn’t a bright object in the frame you’re fine with this lens.

I’d like to also carp about calling this a “kit” lens. Most kit lenses started as 35-70 mm zooms. At the time this zoom was definitely a prized accessory optic—able to do portrait work and small groups at weddings—and never sold as the standard lens on a production camera.

Compared to 70-210mm zooms, the 75-150 mm zooms were smaller, lighter and took standard filters you might already have.

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. ...
