Viltrox 85mm f/1.8 STM Review
The Viltrox 85mm f/1.8 STM is available in several forms for the Sony E-mount and the Fujifilm X-mount. OpticalLimits tested the Viltrox PFU RBMH 85mm f/1.8 STM version for the Fujifilm mount recently.
Some key features of the Vitrox 85mm F1.8 include;
- Bright f/1.8 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over focus position when using shallow depth of field techniques.
- One extra-low dispersion element and four elements made from highly transparent glass contribute to reducing a variety of aberrations in order to produce well-corrected imagery with accurate color and high sharpness.
- HD Nano multi-layer coating has been applied to individual elements to reduce flare and ghosting for improved contrast. Also, this coating is water-resistant to help protect the exposed surfaces from moisture.
- STM autofocus motor delivers quiet and precise focusing performance along with a minimum focusing distance of 2.6'.
- Electronic contacts convey Exif data as well as permit camera-based aperture selection.
OpticalLimits was impressed by the lens giving it the following score breakdown;
Optical Quality: 3.5 out of 5 stars
Mechanical Quality: 4 out of 5 stars
Price/Performance: 5 out of 5 stars
OpticalLimits also had this to say about the lens;
The Viltrox PFU RBMH 85mm f/1.8 STM is an attractive medium tele lens for Fujifilm cameras. It is sharp across the image field - especially at medium aperture settings - and it doesn't show any substantial weakness across the other characteristics either. Lateral CAs are low as are image distortions. There is a bit of vignetting at f/1.8 but it's nothing out of the ordinary (on an APS-C sensor at least). A very positive aspect is the quality of the bokeh. Image highlights are nicely rendered at f/1.8 and the blur in the focus transition zones is very creamy. Bokeh fringing (LoCA) is present at large-aperture settings but that's hardly surprising.
It is quite surprising than Viltrox was capable of designing and manufacturing such a mature product as their first shot into the market. Other newcomers struggled much more during their first years (and some still do). Of course, designing a 85mm f/1.8 isn't science fiction but getting all the required acts together at a very attractive price point is an achievement. Thus if you can't or don't want to pay the premium price for a Fujifilm XF 90mm f/2 LM R WR, the Viltrox lens is a worthy candidate for your shopping list.
