Overview

The Meike AF 85mm f1.8 STM GFX is an autofocus portrait lens for Fujifilm GFX medium format cameras with G mount. Meike states that the lens is optically tuned for 44x33 mm sensors and that 85 mm corresponds to about 67 mm in full-frame terms on GFX. It is aimed at GFX users who want a fast, short telephoto focal length for portraits.

Optical design

The lens uses 11 elements in 7 groups. Meike does not say whether special glass such as ED elements is included. The diaphragm has 11 blades and stops down from f/1.8 to f/16. The spec sheet lists an angle of view of 34.5 degrees diagonally, and the product page shows MTF charts for f/1.8, f/4 and f/8. The minimum focus distance is 0.65 m with a maximum magnification of 0.17x.

Autofocus and handling

Focusing is driven by an STM stepping motor, which Meike describes as quiet and suited to stills and video, with face and eye tracking support. An A/C switch on the barrel selects how the aperture is controlled: in A mode the camera sets it automatically, in C mode the body controls it according to its exposure mode. The filter thread measures 62 mm.

Build and size

The barrel is made of metal with a retro design. Meike quotes about 406 g, with a diameter of 83.3 mm and a length of 93.95 mm. For a medium format lens with f/1.8 that is a compact package.

Where it fits

Within the GFX system the closest first-party options in the database are the Fujifilm GF 80mm F1.7 R WR and the Fujifilm GF 110mm F2 R LM WR, while the Fujifilm GF 63mm F2.8 R WR offers a wider view. The Meike AF 85mm f1.8 Pro STM in the database is a different lens for full-frame mounts and should not be confused with this model.

Pros and cons

Pros

Autofocus portrait focal length for GFX with f/1.8 maximum aperture
Metal barrel at about 406 g
11 aperture blades
Standard 62 mm filter thread
A/C aperture switch and face and eye tracking support according to Meike

Cons

Minimum focus distance of 0.65 m limits close work
No stabilisation in the lens
Image quality information is limited to Meike's own MTF charts

Verdict

The Meike AF 85mm f1.8 STM GFX targets GFX owners who want an autofocus portrait lens from Meike with a sensible feature set: f/1.8, STM autofocus, metal build and a common filter size. Because the technical data come from the manufacturer alone, independent measurements are worth checking for demanding work.
