Between you and Dlee13 I’m having second thoughts about my 12-24mm/24-105mm scheme. Are you happy with the 28-75mm?
It's my default lens at home, not as much when I go out (FE 35). It's on the level of the 12-24, constant 2.8 is so convenient, it feels like I have my 24-70ii back, without the bulk and weight. Close focus is pretty darn nifty. Bokeh may be an issue @ 75, dependent on the background, I'm just not terribly picky with the lens and performs well on the R3.
On the flip side, shooting most of my snaps with the A9, the Tamron won't even give you 15fps, only 10. That's a pretty big deal once you warm up to the camera. The A9 is a little beast, and the difference with fully native lenses is noticeably better. 10 vs 15-20 fps you will recognize with use. It bothers me a little, however the Tam is so nice, not going to add any bulk to my kit, ide rather keep it small and take the fps loss.
12-24f4 vs 17-28f2.8
I run into a few issues and may simply run both.
Internal zoom + super wide + gimbal = pure movie making magic.
Filter system, 77mm filter trick vs 67mm, both really convenient, either way I'm ok.
Low light, again 2.8 is nicer.
The majority of use for either lens would be landscapes and video, not much people photography where low light and bokeh is important, so the draw for the 17-28 isn't super high. I may still buy it just because the 28-75 has been so Impressive.
I'm still caught up in the honeymoon phase with the CV 21, much love.
