MC Macro-Revuenon 28mm f/2.8 - my winter wonder lens


The lens reveals only that it was produced in West Germany. The actual manufacturer is not visible. The name "Revuenon", however, indicates that it was sold by the large German mail-order company "Quelle". Under the brand "Revue", "Quelle" sold relatively inexpensive, sometimes also very solid cameras and lenses since the seventies of the 20th century. Various manufacturers have supplied "Quelle", like Cosina or Chinon. German supporters are also well-known, such as the East German Practica or the Enna- Factory in Munich.





The Enna-Factory was founded in Munich in 1920 by Alfred Neumann. After his death the company after 1945 was led by his son-in-law, Dr. Werner Appelt as "Enna-Werkoptik-Gerätebau Dr. Appelt GmbH & Co. KG". It still appears to exist, but the production of lenses was discontinued in the early 1990s. Today the Munich-based "Enna-Werk" is a manufacturer specializing in engineering plastics.

This lens is (company intern name) a so-called "Ennalyt" 28mm f / 2.8 with metal bayonet, a lens of the lower price class. Amazing is the minimum focus distance of just under 20 cm.

The statistics:

Focal range: 28mm (prime lens with M42- or Pentax PK-mount)
Apertures: 2.8 to 16
Aperture blades: 6
Minimum focus distance: 19 cm (7,5 inches)
Filter: 52 mm
Dimensions (d/l): 65mm/54(44)mm
Weight: 176 gr. (6,2 oz.)
Data on the optical structure were not found.

The lens is exceptionally light, the feel is horrible like a yoghurt cup. Most of the lens is obviously plastic, but the bayonet is metal. Nevertheless you can use it well, the mechanics is precise. Nothing sticks or is worn out. Somehow it is German value work.  I have paid for this lens only 25 euros, on Ebay and on other Internet platforms you get them however already from 10 euros.  On various flea markets you can find this lens together with old cameras and gets the lens practically free as a gift.


What immediately strikes is the sharpness in the center of the image. Even with aperture open, the resolution, as well as sharpness and contrast in the middle of the photo is very good. Stopped down does not bring any improvements.  Only the sharpness to the edges is better: from aperture 4.0 the whole circle of images from one to the other sharp as a razor blade. You cant complain.
In backlight, the lens is very good-natured. The resulting flares are not too disturbing. The bokeh is - depending on the background - very restless to soft.

Particularly fascinating is the low focus distance of under twenty centimeters. This allows easy-to-use macro photos. I guess the macro magnification factor is 1:5.  This is quite remarkable for such an old lens and is quite useful for everyday use.

Let's summarize:  The lens is very cheap to buy, also feels very cheap. The optical calculation is excellent and the photos are very sharp and contrasting. So to speak a yoghurt cup with cream filling.
For me, the optical quality of the lens was really a surprise. I can recommend anyone to buy this lens, which gets them cheap to buy.
Here are a few photos I shot in the last weeks with this lens:
