'Camera Review - The Konica Genbakantoku 28WB, a ruggedized and weatherproof shock impact resistant automatic 35mm AF film camera for the construction industry'


Introduction and Overview

The Konica Genbakantoku (Site Supervisor) 28WB is a ruggedized and weatherproof 35mm AF film camera produced by Konica, a Japanese manufacturer whose products includes film, film cameras, camera accessories, photographic and photo-processing equipment, in 1988.

Targeted for the construction industry, the camera is off the series of 35mm AF waterproof, dust, sand proof and anti-shock impact resistant cameras which Konica produced from 1988 to 2001.

These cameras were normally in dark green, dark blue or dark grey utilitarian colors, while a later ECO model was produced in orange. Model range includes bodies with 28mm and 35mm fixed focal length, 40mm-60mm switchable dual lens, and a 28-56mm zoom lens.

All models are powered by a 6V 2CR5 battery pack and are DX coded.

Common to all the models are the basic operation and display modes for these cameras, which consists of a Power button (On, Off), Mode Button – Auto Flash (default mode), Flash On, Flash Off, Self Timer, Infinity Focus, and a recessed Rewind button. Late models have a +2 EV snow/backlight compensation mode.


Basic Camera Features

The Konica Genbakantoku is actually rarely seen outside Japan, and just as well not much information about it is available on the web. It is known, however, that the camera is fitted with a sealed autofocusing 28mm F3.5 lens of 8 elements in 7 groups design. Minimum focusing distance is 0.5 meters, a shutter speed range from 1/4 to 1/280 second, and metered by a CdS sensor with a range of 5.5 to 16.5 EV (ISO 100).

The chunky squarish body of the Genbakantoku is accentuated with a bulging handgrip on the right side of the body, with the shutter release button on top of it. The handgrip is also the housing for the 2CR5 battery pack which is required to power the camera. With the battery pack loaded, the camera is still fairly light, and comfortable, and it weighs in at 385 grams.

Behind the shutter release on the top plate of the camera is the power On/Off button, and an LCD panel which displays the exposure counter, battery level, flash (auto, on, off), self-timer and infinity focus selection. A recessed film rewind button fills up the panel.

The built-in flash has a range up to 5m at ISO 100 and 10m with ISO 400 film. Film loading and advance are automatic with a motor drive.

The film check window is on the film back. Date versions of the Genbakantoku can record the year up to 2019 and powered by a CR2025 battery.

Access to the film chamber involves twisting a knob on the left-hand side of the camera body to release the camera back. The battery chamber is accessible from the bottom plate of the camera.

The film box is fairly standard as seen on most 35mm film cameras and loading the film is fairly intuitive. All you need to do is to just pull the film cartridge leader to the arrow indicated in the film chamber and close the back. Film forward wind to frame 1 is automatic.


Viewfinder Readout

The viewfinder readout is a simple single bright frame line with parallax correction indicators and the autofocus spot. There are 2 LED lights which light up just outside of the viewfinder, within the peripheral of your view, to indicate focus lock/close proximity warning and flash charging/camera shake.


Camera Mode Selection

Mode setting for the Genbakantoku, as displayed in the LCD panel, is a cyclic selection that rotates the shooting mode from Autoflash On, Flash On, Flash Off, Self-Timer (with auto flash on), and Infinity Focus (with auto flash on), before the cycle repeats. Default mode on Power On is Autoflash On.

The tendency to accidentally set the camera to Self-Timer mode, and the bewildering wait for the shutter to fire after the shutter button has been pressed, is a possibility. You can always look back at the incident as the gaffe of the day.


Autofocus Panning

The autofocus mode of the camera is activated when the shutter button is pressed halfway. Once the distance is locked, indicated by a green LED located on the side of the viewfinder, you are free to pan the camera to reframe the subject image away from the AF spot in the viewfinder. A blinking green LED means that the camera is unable to lock onto the subject.


Flash Recommended

The red LED indicator, located below the green AF lock indicator, lets you know that the exposure setting of the camera is set for use with the flash mode turned on.


Using The Camera

What might be of interest to you is the fact that the Konica Genbakantoku 28WB is an automatic point-and-shoot AF camera with a street fantastic 28mm wide-angle lens and a ruggedized body that can handle rain, splash and a couple of knocks with no harm.

On a higher level of interest is the fact that the 28mm F3.5 lens, albeit being a bit 'slow', is actually a contender for sharpness and clarity with its 8 elements in 7 group construction, and a close focusing distance of 0.5 meters, all of which are uncommon for these types of cameras.
