Review VerdictThe Tokina FíRIN 20mm f/2 FE AF combines many qualities that we like on prime lenses - thus it is faster than zoom lenses and capable of delivering a very high performance, mostly at least. The most impressive quality is the sharpness in the wider center zone even at large aperture settings. However, the image corners are soft at f/2. While this is pretty much irrelevant for shallow depth-of-field photography, it is not ideal for astrophotography for instance. The outer image field improves nicely at f/4 and it is very sharp if not excellent in the sweet zone between f/5.6 and f/8. The field curvature, often a problem with ultra-wide lenses, is very moderate. Image distortions, as well as CAs, are very low. The vignetting is a bit on the high side at f/2. However, most will prefer to leave image auto-correction activated which will care about most of this. A surprise is the high quality of the bokeh. Most ultra-wide lenses have a rather rough characteristic here but the Tokina is better than most. Flare can be an issue in difficult scenes. The build quality follows a Tokina tradition by relying on an all-metal body and a smooth focus ring. Unfortunately, weather-sealing is missing. The AF may rely on a ring-type ultrasonic motor but don't expect light speed. It's rather sufficiently fast for a lens in this class. Sony's DMF, as well as in-body OSS, are supported. The Tokina FíRIN 20mm f/2 FE AF illustrates how mirrorless prime lenses should be - compact and light-weight and that's despite a comparatively fast speed. It doesn't feel alien on a small Sony camera. We hope that other manufacturers will also embrace this concept really. Combined with the impressive peak performance, the Tokina is a highly attractive option in this market segment. Tthe price may not be low but it's still fair considering the large max. aperture.
