MEIKE 50mm f/2.0 Mirrorless Lens Review

MEIKE 50mm f/2.0 Handling and Features

The lens is of metal construction and highly reminiscent of the Asahi Pentax Super-Takumar lenses of the 1960s. The knurled metal focusing ring looks very similar to those classic lenses, and the distance scale is found within a similar cut-out in the lens barrel. There is a depth of field scale provided and distances are marked in both feet and metres. Focusing is by helical thread, the whole optical unit extending forwards as we focus closer. The front element does not rotate, so use of polarising and graduated filters is much easier. A push on plastic lens cap is provided and this shows no signs of being likely to fall off in use.

The focusing initially showed a slight roughness at some points, but soon became much smoother with use. Not the same silky smoothness as those classic lenses, but nonetheless not at all bad. The overall finish of the lens is of a good standard.

The six element in five groups optics are multi-coated, closest focus is 2.5 feet (0.65m) and the lens takes inexpensive 49mm thread filters. Maximum magnification is 0.08x. The diaphragm has eight blades. Finally, the lens weighs just 185g.

The aperture ring is unusual. It has no click stops and remains closed to whatever value is set. This will be useful for video shooters but less so for those shooting stills. The progression of apertures marked is f/2, f/2.8, f/3.5, f/5.6, f/8 and f/22. There is no obvious advantage to this departure from the normal markings.

Although supplied for review in Micro 4/3 mount, the lens is marked as suitable for APS-C format. Accordingly, it is also available for other CSCs including Sony E, Canon M, Nikon 1, and Fujifilm X series. The 35mm-format equivalent will be 100mm on Micro 4/3 cameras and around 75mm on APS-C. This is a useful short telephoto length.

There is a highly polished metal mount, smooth and positive and matching the Panasonic Lumix G6 used for this review perfectly. There are no electronic contacts, so the camera does not know the aperture set. The Lumix G6 works fine in manual and aperture priority modes and meters correctly when the lens is stopped down.

In use, the lens is easy to focus, provided this is done at full aperture. There being no auto stop-down it is then necessary to turn the aperture ring to the desired setting. Unfortunately, the absence of click stops means that this is done by guess unless the camera is taken from the eye to look at the settings. With practice, this guess can be honed and could become quite accurate, but the precise value set will not be known unless constantly checked and noted. Otherwise, it could not be simpler in use.
