Finally got out to play with my Tamron 400 F4 in the daylight... I tried to avoid lugging my 8lb Bogen tripod and just used my monopod. Seemed to work ok. I also tried hand holding a few action shots... it worked OK if I kept shutter speed way up.
This is a bit of a crop, but the lens and K1 combo has resolution to spare.
Still learning my way around this lens, do's and don'ts etc. In some ways, it is more forgiving than I thought it would be and going back to Manual Focus isn't bad as I remembered, in some ways I think the keeper rate might be higher than with AF, especially as I get more practice and re-learn techniques. I can't fit it in my Lowepro Slingshot 302aw with the camera mounted, but it does fit in its own silo with the K-1 in another slot with lens cap, so I will be able to hike with it. I should be pretty buff after a few more long hikes.

Thought I would give the daytime moon reflection a shot.

Jetski action attempt with 400mm turned out ok I think. What should we call manual focus action panning? MFAP? Heh...
