The Olympus M-1 was launched in 1972. But how does this simple film camera compare to others on the market today? In this post, we give you an in-depth review of the Olympus OM 1.
Olympus was quite late in the 35mm film SLR game when they launched the Olympus OM-1 in 1972. For reference, the Nikon F was out in the market some 13 years prior to the Olympus M1. And since they were already late, Olympus had to stand out some way for the M-1 to succeed. And they rightly did so with its design. At a time when SLRs were evolving to be large and bulky, the Olympus M-1 stood out with its sleek, light, and compact form factor.

In fact, it was acclaimed as the world’s smallest and lightest 35mm SLR. Apart from the no-nonsense design language, users really loved the camera’s incredible viewfinder. It’s bright and has a 0.92x magnification, which makes focusing so much easier. The camera is fully mechanical and also sports a light meter. Turning the camera “ON” activates the light meter, but leave it in the “OFF” position if you want to use it without the light meter.
The battery is thus not a matter of concern for the functioning of the camera. But even though the camera features a light meter, Olympus has excluded the auto-exposure modes (aperture priority and shutter priority). Interestingly, although the camera was launched as the M-1, Olympus had to rename it to OM-1 later. It was after Leica approached Olympus concerned with a similar nomenclature (hint: Leica M1) that the camera had to be renamed. This is why you can still come across a few of the initial M1 cameras.

Who is the Olympus OM-1 for?
The sleek and light profile of the camera makes it a perfect choice for light travelers and street photographers. You can fit it pretty comfortably in your bag, or even carry it the whole day with you without even noticing. It is an excellent example of portability at its finest.
The affordability and the inclusion of a light meter mean that it doesn’t matter if you are a working pro taking photos casually, or someone who’s just starting out with film photography; anyone will find it comfortable to work with the camera. While beginners may find the exclusion of auto-exposure modes haunting, I rather find it a better way to learn film photography.
This enables new photographers to learn the relation between the different components of photography: shutter speed, ISO, and aperture. For professionals who want to use the OM-1 in professional shoots outdoors with flash, things can get challenging. The camera has a flash sync speed of just 1/60s. This will overexpose the shots if precautionary measures are not taken.

Design
The design language of the Olympus OM-1 can be referred to as simple yet practical. It has everything that we need, and nothing that we’d ever use. The camera actually set new industry standards for SLRs in terms of functionality, portability, and ease of handling when it came out. Its design made it clear to the market that SLRs could be compact too, and thus changed the course of how 35mm cameras would evolve.
If you look at the top plate of the camera, you’ll get an idea of how minimal the design of the OM1 is. On the right-hand side, you can see that it only has the film advance lever, the shutter release button, the frame counter, and the ISO dial. There’s no exposure compensation dial, no double exposure button, and even the shutter speed dial is missing.
On the left-hand side, we just have the on/off switch for the light meter, and the film rewind knob. The exclusion of the shutter speed dial from the top plate does not mean that you don’t have control over shutter speed. You can set the shutter speed on the camera via a ring mechanism around the lens mount area of the camera. This is similar to the aperture ring mechanism that can be found on the lens. This may seem awkward at first but once you get used to it, you can adjust the shutter speed and aperture with the camera up to your eye.

Viewfinder
The viewfinder on the Olympus OM-1 is one of the greatest talking points about the camera. As soon as you look through the viewfinder, it gets quite apparent that the viewfinder is noticeably big and bright. It is about 30 percent greater than most other 35mm SLRs in the market. That’s because it has a magnification of 0.92x at infinity when used with a 50mm lens.
Also, the viewfinder coverage is about 97 percent of the actual picture field. Thanks to the larg
