What does Tamron's "Di" really mean???

[JoeMA]

The Tamron site only states this:

DI: Digitally Integrated Design, is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras.

Does this mean it is only suited for APS size sensor digitals with a 1.5 or 1.6x factor and not for full frame? This is what Sigma is doing with some of their new lenses. Or is there another meaning to "Di"?

Thanks

It probably doesn't MEAN anything. Tamron, Like Sigma seems to think that more folks will buy their products if they add "Pro" to the suffix of a lens model accompanied by other letters. I always get a chuckle out of the models like: 28-70/f2.8 ATX APO IF Di EX Pro.

I thought I read an add that said it means "digitally integrated" - what ever that means.

No, not at all. There are three lines for smaller sensors, Nikons DX, Sigma's DC, and Canons's EF-S.

Same thing as the DG lenses. Adding some coatings to prevent reflections from the sensor, a few tweaks here or there, that's about it. Many DI and Sigma DG lenses were fabulously on full frames.

Plus Pentax's DA.......though it is only a one lens lineup at the moment, that is out of stock practically everywhere!!
