The Meyer-Optik-Goerlitz Trioplan 50mm f/2.9 boasts superb build quality. The lens has an all-aluminium casing and it features a metal bayonet. With no need for a zoom ring, the manual focusing ring spans a significant width of the lens barrel and is exceptionally smooth to operate, complete with a useful depth of field scale.

At the end of the lens is the aperture ring, with the aperture ranging from f/2.9 to f/22. Note that this ring rotates smoothly throughout the range, with no actual hard stops (except at f/2.9 and f/22), which is perhaps better suited to movie recording than shooting stills.

The Meyer-Optik-Goerlitz Trioplan 50mm f/2.9 is a relatively simple lens with just 3 lens elements in 3 groups. A 12-bladed rounded diaphragm, combined with the fast maximum aperture, helps provide incredibly smooth bokeh blur. There’s no optical image stabilisation, but the Meyer-Optik-Goerlitz Trioplan 50mm f/2.9's short telephoto focal length and fast maximum aperture largely alleviate the need for it.

Manual Focusing

The Meyer-Optik-Goerlitz Trioplan 50mm f/2.9's manual focusing ring spans a significant width of the lens barrel and is exceptionally smooth to operate, complete with a useful depth of field scale. It also has a large rotation angle which enables precise focusing and moves smoothly without any play. The precise engravings in meters and feet help make manual focusing a veritable pleasure, especially in conjunction with the excellent Peaking feature offered by the Sony A-series cameras.

Chromatic Aberrations

Lateral chromatic aberrations, typically seen as blue or purple fringes along contrasty edges, are well controlled with the Meyer-Optik-Goerlitz Trioplan 50mm f/2.9 lens. The crops below give you an idea of what you should expect in a worst-case scenario.

Light Fall-off

Wide open at f/2.9, there's some noticeable light fall-off in the corners, but this clears up quickly upon stopping down.

Bokeh

Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. The Meyer-Optik-Goerlitz Trioplan 50mm f/2.9 lens has an iris diaphragm with no less than 12 circular aperture blades, which has resulted in outstanding bokeh, as you can see in the crops below.
