So what will the new Tammy bring to the table. Digging through the rumored specs on Nokishita Looks like a few promising specs. The optical formula is changed with the addition of another LD element. MFD has dropped down to 2.2 meters from 2.7m. The weight went up by a few ounces. Overall size looks to be about the same with no change in length 257.8mm but a bit more girth, up 3mm. Looks to have 3 VC modes and compatible with the Tap-in system. Max mag had dropped down from 1:5 to 1:3.9. Also added a lock for any focal length.
I'm wondering if they have added the new AF motor to this lens that is in the newer SP lenses. This could be a very competitive lens to the other in the class, especially if they are including better dust resistence.
