Just because, I went out with the Tamron 70-200 f2.8 VC mounted with the Kenko 1.4x TC. So this is a 100 crop from the center of a 280mm f4 shot.

My default ISO is 800 with the super-teles, so that I can get the shutter speed up where needed. When it's really bright, I'll pull it down to ISO 400 and go up to 1600 when the clouds roll in.
