Rumors are circulating that Tamron is about to announce the launch of a lens that would complete its trio of fast zooms for Sony full-frame cameras with the 70-180mm f/2.8 lens. Will it be tiny, how much will it cost, and how will it stack up against Tamron’s two other amazing Sony f/2.8 zooms?
Sony Alpha Rumors is confidently reporting that the announcement will come from Tamron next month, and it would be very much in line with expectations. A few weeks ago, Tamron teased four new lenses, and a longer zoom would make their range of fast zooms for Sony complete. In keeping with the 17-28mm and the 28-75mm, Tamron seems intent on compromising on focal range rather than quality in order to keep size and cost down.
Having spent three weeks using the new 17-28mm f/2.8, intensively testing in my work, I’ve been incredibly impressed (initial thoughts here), and a full review will be published next week. Spoiler: it’s amazing.
Sony Alpha Rumors offers a nice size comparison using the leaked previews to create an indication of how Tamron’s new lens may compares with other lenses. Remarkably, it’s possible that it’s only a shade larger than Tamron’s 28-75mm f/2.8, a lens that is already very compact for its focal range.
As with the 17-28mm, Sony shooters are faced with a very nice conundrum: if you don’t want to splash two-and-a-half grand on Sony’s 70-200mm f/2.8, do you opt for the f/4 at $1,398 and compromise on speed, or go for the Tamron and compromise on reach?
With these zooms, however, an extra factor is at play here, giving the Sony f/4 something of an edge: OSS (Optical SteadyShot). Both Sony options are stabilized and it seems unlikely to me that Tamron is going to include this, preferring to lure customers with another fantastically low price instead. It will be interesting to see how important OSS is thought to be among Sony users shooting on longer lenses. This lens will no doubt be incredibly popular among budget-conscious hobbyist wildlife and sports shooters where managing slower shutter speeds while shooting handheld is not often a concern.
How much will it cost? Will you be buying it? Is Tamron about to release another fantastic lens? Leave your thoughts in the comments below.
