Meyer Gorlitz Helioplan 1:4,5/75




Helioplan 1:4,5/75 is a medium format enlarger lens of legendary Meyer Optik Görlitz.

Meyer Optik produced lenses names 'Helioplan' since the mid-1920s to 1952. All of them have an aperture 1:4.5. There were 6 different focal lengths: 40mm, 55mm for small format, 75 mm for medium format, 105 mm, 135 mm, 210 mm for large format. These were both, photo and enlarger lenses.

All Helioplans have a symmetrical optical design called Dialyte. 4 lenses in 4 groups. Such design also has Goerz Celor lenses and Soviet Oragoz.

My copy Meyer Gorlitz Helioplan 1:4,5/75 has serial number 1099622, it was produced in 1949, this is the first model of DDR Meyer Optic. After Germany division, Meyer Optik was in the DDR. Since 1950, this same model produced with new postwar barrel design.

This copy has a pre-war barrel design, unpainted aluminum. Optic elements is not coated.

The lens has small dimensions: 30mm long, the diameter of the barrel is 33mm. The lens has M42 mount. Perhaps this is an adaptation, because on the internet I saw the same design, but without a threaded mount.

The lens has a filter mount 30mm and a grooved diaphragm fitting ring, it was painted black, but the paint peeled off over the years. On the ring there are aperture numbers: 4.5 - 5.6 - 8 - 11 - 16 - 22.

The aperture closes smoothly and has 14 petals, which have a bluish tinge. This allows you to form smooth circles on bokeh.

The lens looks very unusual on the camera and causes surprise for passers-by people :).

Helioplan 4,5/75 on Nikon

I mount the Helioplan on the Nikon D3100 through a Chinese focusing helicoid 12-17 mm. By chance, infinity was just at the minimal position of the helicoid.

The aperture is slow, but still, sometimes you, can watch branded Meyer discs, similar to soap bubbles, which are clearly visible on Trioplans.

Helioplan 1:4,5/75 Contrast and Color Rendering

Despite in fact, that the lens is not coated, It does have not too bad contrast. Especially when you shoot in clear sunny day, it rendering bright colors.

If you shoot in cloudy weather or indoor, colors are not so bright and gray shades have dominated. This is because of the coating absence affection.
