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—
  1. is always with you and
  2. 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...

2026-03-20-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...
