OLYMPUS OM-SYSTEM ZUIKO AUTO-ZOOM 1:4 f=75-150mm. increase.
In short
OLYMPUS OM-SYSTEM ZUIKO AUTO-ZOOM 1:4 f=75-150mm is a short telephoto lens with manual focus, designed for OLYMPUS film cameras with an OM mount. Is the first zoom lens from OLYMPUS, was introduced back in 1972.
It attracts with its constant relative aperture over the entire range of focal lengths, low cost and excellent assembly. The main highlight is the internal zoom and compact dimensions. With a 150 mm focal length and a relative aperture of 1:4, the lens uses filters with a very small diameter - only 49 mm.
An unobvious advantage is the classic focal length control ring. The vast majority of similar zoom lenses of that era used the more common piston-type focal length setting method (“single-ring” “PUSH PULL” design).
Unfortunately, the image quality is low. A zoom lens that is over 50 years old copes very poorly with backlight and side light and creates a large amount of chromatic and spherical aberrations.

Assembly, control, focus
OLYMPUS OM-SYSTEM ZUIKO AUTO-ZOOM 1:4 f=75-150mm – compact and not heavy.
Lens body made very high quality. The filter diameter is only 49 mm. The focus ring and zoom ring are rubberized, but the aperture ring is not. While focusing and changing focal length, the rear lens of the lens remains stationary.
The lens has an internal zoom - when changing the focal length, the lens has no moving parts.
The zoom ring (changes the focal length) has a tiny lateral play.
The built-in retractable telescopic hood has a narrow ribbed ring for easy control (you can see the love for detail in similar old lenses).
The OLYMPUS OM-SYSTEM ZUIKO AUTO-ZOOM 1:4 f=75-150mm focusing ring rotates approximately 135 degrees. During focusing, the front lens rotates and moves forward. The minimum focusing distance is 1.6 meters. The lens uses an image quality correction system at different focusing distances with floating elements. When changing the focal length, focusing is lost (the lens is not parfocal).
There is a focusing distance scale on the body in meters and feet, but no depth of field scale. The lens does not have a hard stop (hard infinity mechanical stop), which allows you to accurately and quickly focus the lens to infinity under any external temperature conditions. The lens from the review had a significant “overshoot/overshoot of infinity”.
OLYMPUS OM-SYSTEM ZUIKO AUTO-ZOOM 1:4 f=75-150mm has a slight 'Focus Breathing' effect (changing the viewing angle while focusing). When focusing towards the MDF, the viewing angle decreases.
It's great that the lens doesn't use the PUSH-PULL design found in many similar older lenses (e.g. Nikon Lens Series E Zoom 75-150mm 1: 3.5, NIKON Zoom-NIKKOR 80~200mm 1:4, Nikon Zoom-NIKKOR 80~200mm 1:4.5 etc.)

We are waiting for Rubin-1 😋
As a plus you can write down the integration “Black Mist Diffusion Filter” =)
This is the worst 75-150mm zoom I'm aware of. Minolta 75-150mm F4 is a much, much better choice (the lens is almost perfect, great even today), and a good copy of Canon FD 70-150mm F4.5 is also a very solid lens (but there are many bad copies around, with fungus etc.) There are many solid (not as good, but pretty good) 75-150mm lenses out there. This is just a bad example (but it is of older design than most as well).
It’s strange, my lens gave me a much better quality picture. Are you sure everything is okay with the lens? An example with chicory - I didn’t have such “milk”. I won’t attach examples right away, it was a long time ago, but he was quite sharp. Then I replaced it with Tamron 70-300 stabilized, because... It took a long time to focus with my hands.
There were 2 copies from different years, the mechanics and lenses were excellent, but the quality of the photo on the crop was poor, at the level of the worst samples of Yu37, I changed it to 50-200, also not ice, then to 35-105, the latter turned out to be good, I still use it sometimes por.
