Konica's compact Acom-1 — shutter-priority AE SLR, AR mount, entry-level, 1978.
The Konica Acom-1 is a 35mm film SLR made by Konica and released in 1978 using the AR bayonet mount. It is a compact entry-level body closely related to the Autoreflex TC, and different regions used different names for the same or near-identical camera. It was aimed at beginners and casual photographers.
It is a single-lens reflex for 35mm film using the Konica AR bayonet mount. The Acom-1 offers shutter-priority automatic exposure with through-the-lens centre-weighted metering, alongside a manual option. It uses an electronically controlled shutter and relies on a battery for its metered and automatic modes. The body is lighter and more compact than the larger T-series cameras.
The Acom-1 suits students, beginners and travellers who want a small, straightforward Konica SLR with automatic exposure. Its compact size makes it easy to carry as an everyday camera. Its strengths are portability and simple operation; its limits are the basic feature set and dependence on the battery for full function.
When buying used, check the foam light seals and mirror-damper foam, which perish with age. Test the shutter and metering, confirm smooth advance and rewind, and make sure the battery-dependent auto mode responds. The meter was designed around 1.35V mercury cells (PX625/625 type), so allow for a shift with modern 1.5V batteries. Inspect the battery compartment for corrosion and the prism and screen for haze or desilvering.
