Olympus Zuiko 80mm f/4 Auto Macro Review
Olympus Zuiko 80mm f/4 Auto Macro intended for the macro reproduction ratio in the range of from 1:2 to 2.5:1. but that does not mean that it can only work in this area. It performs the best quality within these ranges but can be used and even for portraits and landscapes.
The lens has a symmetrical optical design, with 6 elements in 4 groups. Thereby achieving good sharpness and contrast. Also, it does not have geometric distortion, which is very important for the product photo. I would venture to suggest that the lens is a distant descendant of the legendary Dagor, with the difference that the elements are not glued together and separated by air. This lens was produced in three versions. The first two models: F.Zuiko Macro 1:4 f = 80mm and Zuiko 1:1 Macro 1:4 f = 80mm, had a standard design barrel, single coating, and manual aperture setting. Issued before 1980. The third version, Zuiko 80mm f / 4 Auto Macro, has a multi-coating and has automatic aperture control. Was produced from 1980 through 2002.
Here described a method to adapt the lens to any system with extension rings. Installation of additional rings brings certain inconveniences, but I'm satisfied with this method since I use this lens for performing specific tasks in the studio.

Zuiko 80mm f/ 4 Auto Macro Handling and Mechanics
As mentioned above, the lens has a specific construction. Mounting on the camera is only possible with the special telescopic auto extension tube or extension rings or bellows. It has an unusual construction. The back of the lens unit stands for bayonet mounting on 18mm. What does not allow to set the lens to the camera without a special telescopic auto extension tube or bellows? The lens has 6 aperture blades. The minimum aperture value is 32—the intermediate values 4-5.6-8-11-16-22-32.
The front lens element has a small diameter of about 20 mm. The inscription with the name of the lens is applied on the side of the barrel. Focus ring rubbered. With extension rings, the lens has a standard view of the camera. They are convenient to use.
Zuiko 80mm f/ 4 Auto Macro Focusing
The focusing ring rotates 180 degrees, with a small turn of the helicoid. about 5 mm. I use it together with an extension tube then calculated for a fine-tuning of focus. Focusing is carried out by means of the focus ring. It rotates 180 degrees and has a small turn of the helicoid; for standard stories, that is enough. But for shooting macro, it is not enough. Initially, the lens is designed for use with an extension tube, where it performs the main role in focusing, and the focus ring is necessary for fine adjustment of the focus. The scale of 2:1 or more can be used together with the focusing helicoid.

Zuiko 80mm f/ 4 Auto Macro Sharpness
Even at a wide-open aperture, sharpness is good on the value of 5.6, sharpness increases. Further blanking aperture sharpness is not increased but only increases the depth of field, but this field is not perceptible drop occurs up to f / 16. The optimum aperture for shooting products f/ 8 - f/ 16.

My opinion is that the lens is still more suited for macro shooting and products. It is well fixed all types of aberrations, so the picture is correct, smooth, predictable. It can shoot portraits and people, but to focus on such a distance is more difficult. At f / 4 sharpness suits for portraits. At f / 5.6 already, it seems to me harshly for portraits. But it is better to use a lens on purpose — to shoot the products and the macro, where it shows itself well.
Summary
Overall, Olympus Zuiko 80mm f / 4 Auto Macro very good for shooting products. It has good quality: sharpness, contrast, color rendition. Well-corrected chromatic aberration. It does not distort the image geometry. Also, the lens has a convenient focal length. Most products I shot on this lens.
