A couple of years ago, Metabones released firmware updates for their EF-E Speed Boosters and EF-E Smart Adapters that introduced 10 frames per second max continuous autofocus to the Sony A9 mirrorless camera. Now, Metabones has released a new firmware update which adds that functionality for the Sony A7III, too.
The Tamron 17-28mm f/2.8 Di III RXD for Sony E mount was rumoured yesterday to be announced today, and now that announcement has come. Tamron has today officially announced development of the new 17-28mm f/2.8 lens, along with two others destined for Nikon and Canon full frame DSLRs. The Tamron SP 35mm f/1.4 Di USD prime lens and Tamron 35-150mm f/2.8-4 Di VC OSD zoom.
While the brands battle it out over who has the largest mount and whose lenses can have the widest apertures, Canon’s DSLRs have proven they have no problem with wide aperture f/1.2 lenses. And Samyang has been adding to that f/1.2 collective again, expanding their “XPERT” line of lenses with another new announcement.
Starting off the XP series with a 24mm f/1.4 and 85mm f/1.2 lenses, they later added a 50mm f/1.2. But this left a rather obvious hole. Now Samyang is filling that hole with the announcement of the Samyang XP 35mm f/1.2 lens for Canon EF.
