As you know Sony will also announce a new 16-50mm f/2.8 kit lens along the Sony A77. A trusted source just told me that the 16-50 will have a new actuation motor designed for video use. It may carries the SAM tag but is a new design intended to be on par with SSM. Very likely that the filter diameter of the 16-50 will be 67, as with the 28-75… 72 is a bit of a stretch for an APS model. Another new source told me that “it is definitely an SSM lens, but what’s up in the air is whether it is a G or ZA lens, or neither. Even the lens hood code declares it to be an SSM lens“. I hope to get a 100% confirmation from other sources if the lens will be SAM or SSM. Thanks!
Reminder: As you know the price should be around 750 Euro (or $800 Dollars). The lens itself costs much less than the counterpart lenses:
Canon EF-S 17-55mm f/2.8 USM IS costs around around $300 more at Amazon, B&H, Adorama, J&R, eBay.
Nikkor AF-S 17-55mm f/2.8 $ is twice more expensive! Check at Amazon, B&H, Adorama, J&R, eBay.
