We’ve wondered why Tamron is not making a zoom lens from 20-35mm at F2.8 as they traditionally do? They have launched three separate fixed lenses instead.

Tamron has been aggressively launching the E-Mount lenses of late. The
According to the spokesperson at Tamron Japan, “When using a fixed focal lens, the photographer must decide the composition based on their distance from the subject. This puts the joy of capturing the image exactly as envisioned and the pure fun of shooting on a different level.” The three new wide-angle fixed focal lenses announced today are for Sony’s E-Mount, best for full-frame format. These lenses are:-
20mm F/2.8 Di III OSD M1:2 (Model F050)


24mm F/2.8 Di III OSD M1:2 (Model F051)


35mm F/2.8 Di III OSD M1:2 (Model F053)


The three new models, 20mm focal length is to fully explore the world of ultra-wide-angle, the 24mm focal length as the perfect general-purpose wide-angle lens, and the versatile 35mm focal length is ideal for everyday use. All these lenses share the same manufacturing process and technology, let us take you on a quick tour of what are those.
Close focusing range
All the lenses can focus at a very close range. The minimum object distance for the 20mm, 24mm and 35mm are 4.3″, 4.7″ and 5.9″ respectively. Plus, the maximum magnification ratio for all three is 1:2. This remarkable performance allows users to create dramatic compositions that are unique to wide-angle lenses.
Compact
Weighing in at 220g for the 20mm, 215g for the 24mm and 210g for the 35mm, the lenses are very light, even when all three lenses are placed together, it weighs under 645g. All three new models used the same 67mm filter diameter and even the front lens caps are the same size, reducing the hassle of sorting caps when switching lenses. This will translate to cost savings on spending to buy your favourite filters, you get pictures. All three lenses are the same length: 64mm or 2.5″, good balance with Sony E-mount cameras, especially the A7 and A9 series.

High-resolution
The sophisticated optical formula created with the latest lens design technologies boasts exceptionally high rendering performance from edge to edge thanks to the optimal arrangement of LD (Low Dispersion) and GM (glass-moulded aspherical) lens elements. Additionally, Tamron’s legendary BBAR (Broad-Band Anti-Reflection) Coating effectively reduces ghosting and flare. With excellent resolving power achieved through uncompromising optical performance and camera-based distortion correction.
Auto Focus
The AF drive system uses an “Optimised Silent Drive” (OSD) for quiet operation. In comparison to conventional AF types with built-in DC motors, Tamron was able to greatly reduce the drive noise as well as vastly improve AF performance and speed. Overall, this fixed focal lens series provides superlative AF precision for exact focus even when shooting moving subjects, as well as outstanding accuracy and tracking capability. It also supports various AF features offered by certain Sony cameras, including Fast Hybrid AF, Eye AF, and Direct Manual Focus (DMF).
Moisture-Resistant Construction
All the three lenses come with environmental seals and are located at the lens mount area and other critical locations to prevent the penetration of moisture/raindrops. Best when shooting outdoors under unpredictable weather conditions. The front surface of the lens element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, moisture or oily fingerprints, allowing for much easier maintenance.
