Tokina Firin 20mm F 2 FE AF Análisis | 54 Datos comparados

The Tokina FiRIN 20mm F2 FE AF is a neat, ultra-wide full-frame prime lens designed for Sony mirrorless cameras that delivers very pleasing image quality and strong performance for landscapes, architectural interiors, and astrophotography. Optically, it excels with impressive center-sharpness when shooting wide-open, which remains excellent through f/8, alongside highly controlled coma, astigmatism, and minimal color fringing. On the downside, edge-sharpness is comparatively poor at wider apertures like f/2 to f/2.8, only picking up well from f/4 onwards. Additionally, its autofocus is driven by a slightly pedestrian and audible ring-type ultrasonic actuator, making it slower and louder than modern stepping motors. In terms of design, the lens is a relatively bare-bones and lightweight option, weighing just 464g with a small 62mm filter thread. Its main advantages include a wide f/2 maximum aperture, an expansive 92.7-degree viewing angle, and solid build quality with a high-precision handling feel. However, it has notable design omissions, lacking any physical switches or buttons, which means it completely lacks an AF-MF switch and a physical aperture ring. Users must rely on in-camera menu settings to switch...

The Tokina FíRIN 20mm f/2 FE AF is a compact, light-weight, and beautifully constructed all-metal ultra-wide prime lens designed for full-frame Sony mirrorless cameras, costing around 900 USD/EUR. A major standout feature is its exceptional, near-perfect center sharpness between f/2 and f/5.6, capable of outperforming a 42-megapixel sensor. It also features a smooth bokeh rendition that surpasses most lenses in its wide-angle class, very minimal field curvature, and low image distortion and chromatic aberrations, which are easily resolved via in-camera corrections. Additionally, the internal focusing system ensures the physical length remains constant during use. However, the lens has notable trade-offs, particularly regarding its autofocus speed, which is quite slow by modern standards. Manual focusing works "by wire" with an indirect, loose coupling that requires turning the focus ring significantly for minor adjustments. Optically, the lens suffers from heavy vignetting at f/2 (around 3EV light falloff) and soft corners at wide apertures, meaning you must stop down to f/4 or f/5.6 to get good to excellent edge performance—making it less than ideal out-of-the-box for astrophotography. Finally, the lens lacks weather-sealing and...

The B&H Explora review highlights the Tokina FiRIN 20mm f/2 FE AF as a sharp, fast ultra-wide prime for Sony E-mount, praising its exceptional center-to-edge sharpness, accurate color, and minimal distortion. The lens offers robust build quality, seamless integration with Sony systems, and beautiful bokeh at f/2, making it a strong contender for landscape and street photography. While it excels in performance, the review notes a noticeable hint of vignetting at f/2, although this light falloff is easily managed by stopping down. Ultimately, it is recommended as a reliable, high-performing choice for photographers requiring a fast, autofocus-capable wide-angle lens.

The Tokina FiRIN 20mm F2 AF is a highly capable wide-angle lens designed for Sony E-mount systems that delivers superb, near-excellent image sharpness across the frame even when shooting wide open at f/2.0. Its robust, premium metallic housing is made in Japan and offers excellent weather resistance, making it a reliable and relatively lightweight choice for daily outdoor shooting. Optically, the lens excels with rich, natural colour rendering, very good contrast performance, and excellent control over chromatic aberrations. Furthermore, it boasts low-to-zero comatic aberration, which—combined with its bright f/2.0 aperture—makes it an exceptional option for astrophotography, timelapses, and travel videography. Despite its stellar optical performance, the lens exhibits a few notable drawbacks, particularly regarding its autofocus mechanism, which is relatively noisy and can bleed distracting background sounds into recorded video footage. The physical build lacks a rubber weather-sealing ring on the mount, and the exterior engraving quality could be improved. Image performance is slightly hindered by mild light fall-off (vignetting) and pincushion distortion at wide apertures, though both are easily correctable using Adobe lens profiles. Flaring can also become visible...

The OpticalLimits review concludes that the Tokina FíRIN 20mm f/2 FE AF is a highly attractive, compact, and lightweight ultra-wide prime lens that integrates beautifully with small Sony full-frame mirrorless cameras. Mechanically, its standout pros include an impressive all-metal body construction and a smooth manual focus ring that supports Sony’s native Direct Manual Focus (DMF) and in-body stabilization. Optically, the lens delivers excellent sharpness across the wide center zone even when shot wide open at f/2, showcases very low image distortion and chromatic aberrations, has moderate field curvature, and provides surprisingly high-quality bokeh for an ultra-wide lens. Furthermore, it offers a relatively fast maximum aperture for its class at a fair price point. However, the reviewer highlights several optical and mechanical cons that potential buyers should consider. When shooting wide open at f/2, the lens suffers from soft image corners and somewhat high vignetting, making it less than ideal for astrophotography without stopping down to its sweet spot between f/5.6 and f/8. Lens flare can also present a challenge in difficult lighting conditions. Physically, the lens lacks weather-sealing to protect...

The Tokina FíRIN 20 mm F2 FE AF is a bright, ultra-wide-angle prime lens optimized specifically for Sony full-frame system cameras, offering an exceptionally high price-to-quality ratio. Optically, the lens is an outstanding performer, serving as a "resolution champion" that delivers very high center sharpness even when shot wide open at f/2. This large aperture allows photographers to capture images with an impressive, smooth background blur and beautiful 9-bladed sun stars at smaller apertures like f/13. Additionally, it features full electronic communication with Sony bodies, enabling automated in-camera lens corrections for distortion and vignetting, as well as full compatibility with the camera's internal image stabilization (IBIS) and Fast Hybrid AF system. However, the lens does come with several distinct drawbacks that users should consider. The ring-type ultrasonic autofocus motor is neither exceptionally fast nor quiet, meaning the motor noise can easily be picked up by the camera's internal microphone during video recording. Optically, the lens suffers from noticeable image field curvature at f/2, resulting in softer corners unless the aperture is stopped down to f/4 or f/8. Significant vignetting and...
