D FA* 70-200mm F2.8 In-Depth Review (and Tamron 70-200mm comparison)

We've just posted our in-depth review of the new Pentax 70-200mm professional zoom! As the first digital-era full-frame star lens, it sure delivers. bdery did a great job testing the lens and comparing to the more affordable Tamron 70-200mm F2.8:

Nice review. Thanks! I was debating on this lens or another cheaper option.
Any info on focus breathing with the lens at closer range? Does it adhere reasonably to the expected focal length?

Go to this video about five minutes in. He's done the math.

good find - thanks

In a purely academic way, I'd like to see the results for the Pentax - I wouldn't give it up for anything, and as Matthew Gore says, in the real world it's not something you think about but I'd like to know the figures I was actually dealing with. Interested also for confirmation that the Canon actually has 'positive' focus breathing - it's something a lot of people suspected.

Agreed. Maybe someone will chip in money for the forum to start testing this.
