Random research notes on Olympus cameras and lenses, hopefully of use to someone.
When using a camera, I normally close my left eye and look through the viewfinder with my right eye. After doing that for awhile (half an hour, say), my vision gets blurry and it takes awhile for my eyes to want to focus together properly again.
A 55mm lens (prime or zoom) gives almost an exact 1:1 magnification in the viewfinder of an Olympus OM camera, which means I can keep both eyes open while using the camera. Today I experimented and found that the optical path on the OM-1 and OM-2 cameras is different than the optical path through the viewfinders on the OM-3Ti and OM-4Ti cameras. With the OM-1 and OM-2, using a 55mm lens, keeping both eyes open works fine - the images in both eyes coincide. However, with the OM-3Ti and OM-4Ti in landscape orientation, the images do not coincide: the image in the viewfinder (my right eye) is below the image seen by my left eye. If the camera is held in portrait orientation, the images in both eyes align properly. (I have no idea why the difference?)
I experimented with using an OM-2 and a 55mm lens, keeping both eyes open, for over half an hour. It is easy to focus the lens, and most importantly, my eyes did not fatigue and get all blurry. In addition, this worked whether or not I had my glasses on.
So, I think I've found my new favorite camera and focal length combination for when I will be taking lots of pictures of the scenery and a different focal length is not required.
