Pictures have leaked of the coming Tamron 70-300. Most 70-300 offerings are considered low-quality kit lenses, but the series Tamron is fleshing out is notable for the high quality exhibited despite the kit-level price. For this reason, mirrorless shooters for Sony, L-Mount and Nikon – the mounts supported so far – have been eagerly awaiting this lens.

It looks very much like the 70-180 released a year ago, using the same design elements. That lens was difficult to keep in stock due to it being being very close in quality to OEM manufacturer’s 70-200 f/2.8 offerings, yet about half the price, and significantly smaller in size. This lens, though, will have a maximum aperture ranging from 4.5-6.3, which does indicate perhaps more of a quality compromise.

No reports yet on actual performance.
