Could Tamron’s New 20mm Lens Be The Best-value Sony Optic On The Market?

Check out the image quality from Tamron’s latest wide optic…

Sony photographers are becoming spoilt for choice these days when it comes to wide optics, but one of the newest lenses on the market is Tamron’s 20mm F/2.8 Di III OSD M1:2 for Full-Frame Sony E-mount could be the best-value option on the market today.

The fast aperture prime optic supports Sony features including Fast Hybrid autofocus, Direct Manual Focus (DMF) and Eye AF. What’s more, the lens is future-proof as it’s compatible with in-camera lens corrections and even firmware upgrades. 

The Tamron 20mm features a moisture-resistant design.

Suitable for professional use thanks to a moisture-resistant design, the front element of the optic is coated with Fluorine to protect against dust, oil and water – the everyday enemies of a pro shooter. The 20mm focal length is well matched for landscape and architecture photography on a full-frame Sony cameras such as the a7RII.

However, pairing it with a crop sensor body like the a6500 will switch up the focal length to 30mm, making it a good choice for street photography. What’s more, the design also includes a 1:2 macro feature to help you capture close up imagery, too.

Measuring 64mm – the same as the other recently announced 24mm and 35mm F/2.8 Di III OSD lenses – the lens is designed to balance perfectly with Sony mirrorless E-mount cameras and the fast f/2.8 will enable photographers to shoot handheld in low light conditions. Interestingly, the 20mm, 24mm and 35mm primes have the same filter thread as Tamron’s popular E-mount 28-75mm RXD and 17-28mm RXD zoom lenses, meaning photographers will be able to use the same circular polariser or ND filters.

Along with the impressive features and design, the price-tag of just £399 will prove popular too. To show off the impressive image quality this new optic is capable of, Tamron also released some sample imagery taken with the lens.
