Mike, thanks for posting an image with this new lens - that is great sharpness across the frame for F4. Looked at your Flickr - some very nice images. On this headshot, I think I would take the slightest exposure off the hotspot on his forehead with a radial filter, or similar, in LR.
Thank you! I'll take a look at the highlights on his forehead. I haven't been posting on Flickr as much as I used to but thank you for taking a look. The Tamron 70-200 G2 has been great so far, fast accurate focus and remarkably sharp focus. I'm very, very, very happy with it. A couple non-portrait shots I took in Philly the other day:
This marginally qualifies as a headshot, this one at f/2.8.
