( recently read) johnmcl7 - that's a very fine picture (Post#7);well deserving of the £750 Tamron lens (Az Dec18) and your Full-Frame camera. The stab and steady hand shows.
Well done.
The only "snag" as I see it, is the 150mm starting f-l.... I recall my days with a Nikon ff film camera; where the 35-105 was almost permanently on, although I had a f/3.5 200mm.
Sadly in those days no stab!
Cheers.
