2026-05-14 Nikon SB-15 Flash

The Nikon SB-15 is a hotshoe based flash that works well with Nikon film cameras.*
Specifically it works in Through The Lens mode with the Nikon FA, FE2, F501/N2020, F-301/N2000, FG and Nikonos-V (via V-Type Sync cord)—

the usable film speed range is ASA/ISO 25-400 with FA, FE2, FG and Nikonos-V
the usable film speed range is ASA/ISO 25-1000 with F-501/N2020 and F-301/N2000
usable aperture range for all cameras from f/2 to f/22 (at ASA/ISO 100)

For non TTL use there are two auto ranges, depending on film speed. For example at ASA/ISO 100 A2 setting at f/4 gives a range of 0.6 ~ 6.2 m (2 ~ 20 feet) while the A1 setting at f/8 works from 0.6 ~ 3.1 m (2 ~ 10 feet).

In addition you have full power in manual (“M”) setting and approximately 1/13 power at motor drive (“MD”) setting.
Guide number of 25 in meters at ASA/ISO 100 or 18 with wide panel installed. Guide number of 41 ASA/ISO 25 and feet, 30 with Wide-Flash Adapter.

The flash covers 60º H and 45º V—so lenses 35mm and longer. With the Wide-Flash adapter the coverage is 70º H and 53º V so coverage extends to 28 mm lenses.

Colourful Calculator Dial

The SB-15 flash works best—8 second recycling— with alkaline-manganese batteries (160 flash), while Ni-Cd batteries will work—9 second recycling—with lower performance. Zinc-Carbon are the worst choice giving just 60 flash per set of four.

The instruction manual for the SB-15 is 53 pages long. There are a lot of settings and uses to cover because the settings are different for different Nikon cameras.
The flash unit itself can pivot 180º. It is usually set horizontally with the calculator dials facing up, but you can rotate the unit so the dials are down if you need to tilt the flash tube down for close-up work.
The flash will change the display inside Nikon cameras to indicate charge and exposure information.

The flash reflector release

The battery holder is particularly clever. It is a clip that allows fast changes.

This flash had a damaged clip, later repaired with glue

The battery clip only fits into the body one way, as the two clips are different widths.

The SB-15 has a PC sync connection so multiple units can be wired together.

* Note: Having at least one SB-15, I still haven’t checked the sync voltage. Various internet sources have said its voltage is slightly over 4V, which would mean the SB-15 is safe for all digital cameras, or conversely the sync voltage is too high for anything but the film cameras listed above.

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...
