I'll put up a very quick an' dirty set with the SprTac 300/f4 tonight. Attached is about the best I've gotten recently with a Tam 1.4 TC. Shamelessly cropped and tweaked, but that's the whole point, right?
in terms of shameless crops, see the following from sigma 70-200 F2.8 with 2x TC. this crop is only 10% of the K10D full frame area.
I use this as a standard of sorts. it is what I expect from a good tele zoom with a good TC
