Pine bud with Mamiya Sekor 50mm f2 and extension helicoid Compatibility and adaptorsĭue to M42 mount, the Mamiya Sekor 50mm f2 is a very adaptable lens and works well with mirrorless and SLR cameras. Mamiya Sekor 58mm f1.7 or the Mamiya Sekor 55mm f1.8 are both noticeably better lenses for close-up photography. The helicoid adapter also uses up a portion of the remaining light, making it tricky to use hand-held. It is not a fast lens and needs further stopping down to increase sharpness, but that makes resultant apertures very small. Macro performance of the Mamiya Sekor 50mm f2 is good – the images are well defined, but getting good shots is difficult. Nonetheless, it is possible to improve that by using an adapter with a helicoid. The minimum focus distance is about 50cm, which does not allow enough magnification for macro photography on its own. Used wide-open shows bubble-bokeh effect with pronounced edges on the specular highlights. In some cases, busy backgrounds can look good and form a character of the vintage image, but it is very much a matter of taste. I do like the separation between objects, but it is not as strong because this lens is regularly stopped-down to f4 – otherwise it is too soft. This lens offers a rendering similar to the other Mamiya 50mm lenses from the 1960s.īackgrounds are rather busy. Flare can contribute to achieving creative light effects for artistic purposes. Photos are sharp from about f4, but quite soft wide open. Images shot with this lens are beautiful and contrasty. Mamiya Sekor 50mm f2 M42 Lens – Side view Mamiya Sekor 50mm f2 M42 Lens – Rear view Optical performance The arrangement of optical elements is identical to the Mamiya Sekor 55mm f1.8 – they both have six lens elements in four groups. The main difference between this lens and the faster Mamiya Sekor 55mm f1.8 is that this lens does not contain radioactive elements. Despite coating, it does flare a lot and loses contrast when pointed towards the sun. It is single-coated with signature Mamiya yellow tint. And it shows – many years of use-and-abuse, and yet this lens looks like new. Construction is sturdy – composed of metal and glass. Aperture selection is pleasant and tactile. Mamiya Sekor 50mm f2 is comfortable to use – the focus ring is large, smooth and well-damped, but not as refined or precise as the Konicas or Canons. Lenses in the range are the top of the line radioactive Mamiya Sekor 55mm f1.4, radioactive Mamiya Sekor 55mm f1.8 and the classic four-element Mamiya Sekor 50mm f2.8 – all worthy lenses in their own right.
