I too chose that Tamron 35-150. It's a real gem. A bokeh monster but also sharp all over if you want. It's a tad on the heavy side but balances very well. Too bad Sony doesn't have anything comparable.
Yes that lens is amazing!
My friend sold his primes and his 70-200 II after buying the 35-150 because he just didn't use them at all, and didn't miss them. I had tested the lens a while back using Reikan FoCal I created a thread about it the results were pretty impressive. And on the A7RV with the better Ibis I can definitely see the difference too, now I don't miss having IS on the lens

The only issue I'm having so far is the 200-600 Sony lens seems to have a lust for higher shutter speeds. I have an OM-1 with their 100-400 (eq: 200-800mm) lens and it can easily be shot in Aperture Priority mode which tends to seek slower shutter speeds down to some ridiculous lower speeds for a long zoom. The Sony not so much. But I'm going to be testing it out further over the next few days. Its a lot to lug around and if it can't do as the Olympus does I may send it back.
I’m not sure how the ultimate degree of stabilization will compare, but are you using the Auto ISO Minimum Shutter speed function? I have it mapped to a directional pad button and it allows you to choose one of 5 levels with the slowest bringing the minimum. The other tool of course is changing the ISO, which I sometimes do. My reference point for stabilization when I used to shoot M43 was the EM1 ii and 12-100 with Sync IS. That was a fantastic system. With the A7R V and a stabilized 70-200 I’ve been able to get 5.5 stops vs. 1/FL, which for me is great as with pixel dense sensors you often need higher than 1/FL without stabilization. In the end though it’s a bit of apples and oranges, the Sony system is larger but the M43 set-up you mention won’t compete for DoF control or base ISO performance. If your M43 system is sufficient, however, then no reason to spend now.
I did a short test handholding the 600 GM with the A7Rv, just for grins.
At 1/400 sec, both shots had no motion blur that I could discern. At 1/250 sec using continuous HI, the first shot had some minor motion blur and would look good unless blown up for a large print. The second one had quite a bit of motion blur. This one is the only one of three I took at 1/250 sec that I feel had no (or VERY little) motion blur.
This was with a large lens and there was a breeze, so I am pretty happy with that.

Oh I understand the drill about higher ISO's and that setting for increasing shutter speed. They are good features but if used as you know there is a tradeoff. I guess I'm just spoiled by the stability and lack of need of upping the ISO's and shutter speeds on my OM-1 to get a fine result. My testing will continue before I throw any towels in. To me at the moment the A7R5 is a bit of a sexy beast, kind of like a new girl that is hitting on you and you can't decide if you want to go out with her on the side and not upset your current girlfriend. oh the decisions.

Yeah I'd say your results are just fine. I need to do some further testing to see if I can get a similar result. I would love to keep the bad boy even with it's slightly higher weight to deal with. We'll see.

Right, actually for ISO I meant decreasing the ISO in order to lower the shutter speed. I find that the auto settings for my Sony and Canon bodies don't allow as low "camera-chosen" shutter speeds as what I can hand hold if I concentrate. Actually with Canon it's a bit easier as I can rotate one dial and it temporarily lowers the ISO long enough to take the shot, then re-sets. As far as I know Sony doesn't have this.
I've been experimenting with the 200-600 on the A7R5 and using the P mode, letting it do its thing. I was using a monopod for these images. Interesting atmospheric effects in the Northern Harrier shot. It was cold and somewhat windy but with sun coming through at times. ("cold" = little less than 40 F, I'm long past my Fairbanks winters)
1/400th f/5.6 ISO 100 293mm (3894 x 2596 crop)
1/500th f/6.3 ISO 400 600mm (4342 x 2895 crop - notice atmos. effect)
Here are a few from a local brunch spot shot for IG. Lenses were the 35 GM, Sigma 100mm Art Macro, and Canon TS-E 50mm Macro. I'm finding the IBIS noticeably improved and it allowed me to balance the background ambient exposure with flash for a few of the shots that day that would have otherwise required me breaking out the tripod.
Couple things I am noticing the gradient sky in these images you just can't get any better very smooth no banding of tone or nothing like that . That's the sensor but also the Raw processing out of C1. The other is the files are just crisp with a ton of presence. Great DR with a ton of elbow room. Highlights hold very very well. That last image I posted with the white petals or flowers just jumps off the page. It takes vignetting well without any increase in noise and even though this is a heavy vignette it's really holding on really well. Credit to Sony and C1 . I have to admit getting back to 61mpx is like a teenager well I just can't say that but you get it.

Oh can I relate to the teenager reply. I have a wonderful and competent OM-1 with some great Pro glass. But this A7RV is talking to me about adding it to my stable permanently. I have had long conversations with my wife about my feelings about this and she understands. She said I have a little time to make up my mind so I just need to hope the weather improves enough to give me the opportunity to really run it through it's paces. What I too notice, is the color depth on this sensor/camera is superb. Rich and delightful outdoor and landscape results, which makes up over 50% of what I shoot. The only challenge has been with the 200-600 which I trying to make work out. It "seems" to desire higher ISO's to stabilize correctly or ideally. Sometimes I can have it down to ISO3200 in lower light and otherwise ISO6400. My OM-1 nails focus in low light so easily I got spoiled. Still figuring it all out.
To me it sounds more like big lens that just needs a bit more support. Maybe try a monopod and take any of that weight off your arms and shoulders. Having a 8 stop leeway means squat if you have a hard time with that size and weight. I use a monopod with a 70-200 in crop mode . I’m indoors but it’s about balance with everything. Size, Weight, focal length, light, speed all have a fine balance here. A monopod takes out some bad elements in that balance
oh the decisions.
