New Sony E-mount lenses from Tamron are on the way
Tamron is a company based in Japan that is a common name in optical components and materials. Therefore, it is a familiar name in third-party lenses for high-end cameras from OEMs such as Canon, Nikon and Sony. This company has recently released a video trailer for new upcoming examples of these products. These lens are all to be E-mount, which are compatible with Sony full-frame units such as those of the a6, a7 and a9 series.
This teaser artfully skirted around their actual lens size and other specs, presumably to build hype prior to their release. However, they were shown alongside other pre-existing E-mount variants, as if to confirm that the new models are of the same nature. The blog SonyAlphaRumors, however, has claimed to be in a position to fill in the remaining blanks.
The site now alleges that all 4 mystery items are FE lenses with an f-stop of 2.8. It has come to its conclusions by analysing the new available images in the context of those for extant Tamron E-mounts, including the 70-200mm f/2.8 and 28-75mm f/2.8 FE. This may indicate that the longest of the upcoming lenses is 70-180mm.
By the same logic, its 3 companions, which are much shorter, may fall into the 20mm, 24mm and 35mm categories respectively. Tamron has announced that these new lenses are not to be launched until October 2019; therefore, we still have a while before confirming this theory.
