Notes on batteries

Lithium batteries have approx. 1.1 to 1.2 times the power capacity of alkaline-manganese batteries.

Lithium batteries feature greater efficiency at low temperatures when compared with alkaline-manganese batteries. Lithium batteries boast consistent performance in terms of recycling times and number of flashes, regardless temperature changes.

NiCd batteries boast a constant recycling time regardless of temperature changes when compared with other types of batteries. Recommended for use in temperatures as low as 0°C (32°F).

Ni-MH batteries feature a constant recycling time but a little longer recycling time at low temperatures when compared with NiCd batteries. However, Ni-MH batteries maintain their efficiency regarding the number of flashes regardless of temperature changes.

Notes on using alkaline-manganese and lithium batteries

Non-rechargeable batteries such as alkaline-manganese and lithium batteries should not be charged in a battery charger as they may explode.

Lithium batteries incorporate internal safety switches. When the battery becomes hot, its safety circuit is activated, cutting off power. This often occurs when the SB-28 is operated in the repeating flash mode. The flash ready-light will not light up after firing approx. 24 exposures. However, battery power will recover when the temperature goes back to normal.

Notes on using rechargeable NiCd and Ni-MH batteries

When recharging batteries, be sure to use the battery charger specified by the battery maker and read the instructions thoroughly.

Recharging should be done in temperatures from 10° to 30°C (50° to 86°F).

Do not recharge NiCd or Ni-MH batteries with their terminals reversed in the charger or before the batteries have cooled off sufficiently.

Overcharging and excessive use may shorten battery life. Do not overcharge and be sure to turn the SB-28 off when not in use.

Because flash consumes a large amount of battery power, rechargeable batteries may not operate properly before reaching the end of their stated life-span or the number of charging/discharging as specified by the battery manufacturer.

If NiCd or Ni-MH batteries do not last as long as they should after being fully charged, they are approaching the end of their life. Replace them with a new set.

SB-28 specifications

The Nikon SB-28 is a venerable speedlight flash that has become a classic among photography enthusiasts, particularly those using Nikon camera systems. Released in the late 1990s, the SB-28 has cemented its place in the hearts of photographers for its robust build quality, reliability, and impressive performance in a variety of shooting conditions.

One of the key features of the Nikon SB-28 is its guide number, which measures the flash output. With a guide number of 38 (in meters at ISO 100), the SB-28 provides ample power to illuminate subjects, even at a distance. This makes it particularly suited for both portrait and event photography where good lighting is essential. The flash also offers a versatile zoom head that can adjust from 24mm to 105mm, allowing photographers to focus the light precisely when required and improving efficiency in battery usage.

The SB-28 incorporates advanced technologies that enhance its usability. One notable feature is the TTL (Through The Lens) metering capability, which allows the flash to communicate with the camera to determine the appropriate exposure settings automatically. This feature significantly simplifies the process for photographers, enabling them to focus more on composition and creativity rather than on technical adjustments.

Another commendable aspect of the SB-28 is its built-in diffuser and bounce card. The diffuser softens the light and reduces harsh shadows, while the bounce card helps to reflect light into the eyes of subjects, giving them a more natural appearance. These features elevate the quality of the images produced, making the SB-28 a popular choice for wedding and portrait photographers.

Performance-wise, the Nikon SB-28 boasts a fast recycle time, allowing photographers to shoot at a rapid pace without significant delays between flashes. It also has a comprehensive range of flash modes, including manual and automatic settings, enabling users to tailor their lighting setup to their specific needs and shooting styles.

In terms of build, the Nikon SB-28 exhibits a sturdy and reliable construction, suitable for professional use. It is designed to withstand the rigors of daily use, with a weather-resistant design that offers protection against the elements.

In conclusion, the Nikon SB-28 is a powerful and versatile flash unit that combines advanced technology with practical features, making it a valuable tool for photographers aiming for optimal results in various lighting scenarios. Its robust performance and ease of use ensure that it remains a relevant choice even years after its initial release.
