Great news... not sure whether to choose this over the 180mm Macro though.. Although this will go well with the D3 as I do have anything to cover that range. Instead of buying Nikkor 70-200 2.8 and Tamron 180mm.. This may solve all the problems..
Tamron announced yet another lens at this year's PMA show, the SP AF70-200mm F/2.8 Di LD (IF) MACRO.

This fast telezoom gets in close thanks to its 0.95m minimum focus distance, realizing a magnification ratio of 1:3.1 at 200mm. Plenty of coatings keep stray light to a minimum whilst a removable tripod mount and clutched focus ring (Canon and Nikon only) help speed up operations. Canon users will see the lens first with release scheduled for March.

I have dwarf cichlids in my tanks! Do you?

Jeffrey, this is a 1:3 "macro" whereas the 180mm macro is a "true" macro capable of 1:1 magnification. read everything and don't get confused when the word macro appears.
benny, does "clutched focus ring" means you have to push the focus ring to engage AF/MF ? which means no full time manual focus (as defined by canon)?

I was reading an article (which I couldn't remember where I read it),
Do we really need 1:1 in Digital Cameras today? Considering the megapixels and highly intelligent post editing software in today's technology.
Your thoughts maybe?
Personally, I prefer a prime when it comes to macro for the speed and quality, but zoom lenses will have its own advantage.

1:1 means at the minimum focusing distance, a 1cm object will be projected onto the sensor plane at a size of 1cm (hence 1:1) whereas a 1:3 lens will project an image 1/3 the object size hence only 3.33mm.
if you NEVER EVER shoot any thing smaller than 2 inches then it doesn't make a difference to you

I think 1:1 is good - but sometimes not enough even. It's not the same when you take a photo and keep the original (maybe crop a bit on the side) than take a photo and heavily crop it to look nice. The latter doesn't give as much satisfaction, plus you probably can't print very big after cropping a lot.

Agree with you Billy. QED-indeed is worse than sms lingo. tsk tsk... TYHI=there you have it!
My old Nikkor 80-200 is a 1:4 lens. So this 1:3 is not really a big step. Must see the MTF data. Some lenses have terrible performance at closest focussing distance.

I would strongly suggest you guys try googling for Q.E.D.
