According to Photorumors, Tamron will be releasing a 28-75mm. f/2.8 Di III RXD lens on April 27th. The company hasn’t mentioned anything about how much it’s going to cost yet. However, Sonyaddict reported in March that the pre-sale price listed in China was Y5,300.00 (about $840) on Taobao.com. If that value is accurate, it’s going to be $1,349 cheaper than Sony’s very own 24-70mm.
There’s no doubt that Sony full-frame cameras have become a gamechanger in the industry in the last few years. They’re cheaper, lighter and packed with more features than the DSLR options from other competitors. With all the numerous benefits they offer, it’s no surprise many photographers have made the switch to the Sony system.
Nevertheless, some photographers still hesitate to make the transition because their lenses can be expensive. Furthermore, there also aren’t many third-party manufacturers that offer quality and more affordable choices. And if you want to use an old lens, you would have to screw on an adaptor. Depending on the compatibility, you may not even be able to use all its features properly.
However, the release of the new Tamron lens might change all that. Apart from the price, it’s more light and compact than the Sony option. It only weighs 550 grams and is about 117mm. long. Meanwhile, Sony’s 24-70mm. weighs 885 grams and is 136 mm. long. Perhaps the only downside is that the Tamron E-mount lens doesn’t have image stabilization. But frankly, it doesn’t matter much since Sony’s In-Body Image Stabilization (IBIS) is highly dependable. Any shaking will be corrected inside the camera itself.
To this day, Canon and Nikon are still trying come up with a product that can compete with Sony’s full-frame mirrorless line. Now that Tamron will soon release their affordable lens, Sony would have even more [indirect] advantage over these camera manufacturing giants.
UPDATE: Tamron 28-75mm F/2.8 Di III RXD is now available for preorders at the price of $799. You can expect the shipping at the end of May 2018.
