I told @AiDon I had gotten a new toy to go hiking with - a Tamron 28-300 F3.5-6.3 for Canon full-frame cameras. It has been great so far, and I especially like the fact that it only weighs 540 gm - lighter than many of the more limited zoom lenses I own. I tested this on an extreme shot - 1/8000 sec, f 6.3, iso 12800 at 300 mm. (I forgot to get consent from the model again).
I used Topaz Studio - AI Clear, then Reduce Noise, (I liked that better than the reverse order) and finally Vignette.
