Has an excellent write up, lovely build, and decent focal range:

Nice, could live with 200mm and the f2.8 is useful (but not top of my priority list).

Price bound to go up but seems a decent lense. Don't know much about it. Quality is a given with Nikon branding?:

I'm probably leaning toward the Sigma 100-300 at the moment, but could easily be converted ;)
