Can someone w the new sigma 24-70 lens confirm if it can do 20fps in combo w the A9 or is that still only available w Sony specific E lenses? TIA
I have yet to find a SD card that can capture at 20fps in long bursts. I only get ~15fps with Sony's 300R/299W cards with the A9.

It’s dependent on lens, and they slow down based on action. Most only do 15
I would not say most, but yes, there is are several older lenses than only do 15 with AF-C tracking, such as FE 55/1.8, FE 90/2.8, 70-200/4... Lens specifics can be checked here
One thing that will affect fps is "Priority set in AF-C". If you set that to "AF" and can cause big slowdown in fps in any body when light conditions are challenging. Also, the actual lens AF reaction capability (focus motor speed, focus group weight, one or multiple focus groups) can effect slowdown if one is shooting in "AF" priority as described above.
Yea these reviews are eeehhh not great. Most just show a quick shot of a scene. I always preferred dustin abbot's reviews since he is very detailed in different aspects (AF, handling, image quality comparisons ect.). So far from one review I saw from Enzo's photography actually did show a decent amount of photo samples + AF performance. The video I just posted does also show how silent the AF is which is a plus but the photo samples were not great.
So I’ve got it in hand. I haven’t had much time to do anything with it besides grab a few quick pics while waiting for our salads to be made to use some good old confirmation bias to convince myself the bokeh was notably better than the Tamron. I’m probably gonna go for a walk in about an hour and take a few more deliberate photos, though despite my earlier complaint about not having any people in them that will still be the case here. I’ll have to wait until I pick up my daughter from school to try it out on a person because wifey’s not having it today.
What I can say and offer briefly is that my very anecdotal observation on “build quality” is that it’s very solid, which is just to say it feels very solid in the hand and inspires a bit more confidence than the Tamron. I never though the Tamron felt cheap, but the difference with both in hand is noticeable. The weight is noticeable, though not extreme. Then again I’ve been doing reps with the 135 lately. The zoom and focus rings are reversed compared to the Tamron, but I believe it’s the same as the GM though it zooms in the opposite direction. The focus ring feels much like any other focus-by-wire lens - manual focus enthusiasts will find nothing win them over here.
The lens hood feels nice and solid. The petals are a hard plastic, but the portion closest to the lens has this rubberized grippy finish which is nice for, well, grip but also really nice if you want it to be covered in dust or any particles in your bag. Maybe it’ll collect the dust instead of letting it get in the lens...
The zoom lock is a nice feature, but it’s a “soft lock.” It will stop the lens from accidentally extending it seems, but you can override it by deliberately twisting the lens. I really just use primes, so I’m not familiar with how this compares to other zoom lenses with this feature, but you can’t lock the lens in any particular position other than 24mm.
Here’s something I do think is worth sharing. I had noticed in the Digital Goja video that the lens looked downright small, but chalked it up to maybe his hands being larger than mine, which are fairly small. But, the lens really is about the same height as the Tamron. It’s obviously got greater girth, but without the lens hood doesn’t create a substantially larger footprint when on my A7III. Here are some quick cell phone shots for illustration.

How about removing the lens caps for a comparison ;-)
Another review, German this time around. There's a good number of comparison shots between it and the Sony GM. If I'm not mistaken the Sigma seems a little wider at 24? Might be an interesting perk.
They often shoot a little wider and then when distortion is corrected they are closer to the stated focal length.

Well I can't find one and I start shooting in LA 1/1/2020 and I need my 12-24,35 and my 24 all for a event with at least 2 shooters so I may have to wait on this. I need them at 24 in crop mode. Small files are needed

wow, the Sigma seems to be quite a bit better than the Sony GM
Mine just arrived. I'll post some images later after taking care of a sick wife and daughter. I can say right off the bat that the lens feels very well built (as good as the 24GM and 16-35GM). It's centered at all focal lengths. Focus is fast and quiet. The Sigma appears to be very sharp at all focus lengths wide open except for a very slight softening at the extreme corners. I'm very impressed so far with the limited shots I've had with it.
Oh, and regarding the T-stop issue, I tested it against the 55/1.8 which has a full 1.8 T-stop and the Sigma at 55mm/f2.8 gave the EXACT same exposure values as the 55mm at f2.8 (ISO 100, aperture priority, tripod). I'll do more testing in that regard, but I was pleasantly surprised. More to come later today.

That’s good to know. I didn’t do a controlled tripod test, but took similar shots on my walk with the Sigma and Tamron at 2.8 and concluded I couldn’t tell enough of a difference to obsess over it.
You can thank my sick wife who agreed to let me take her picture even though she feels terrible and had mascara rubbed around her eyes. In the pics below the first image is a resized whole image shot and the second is a crop. It's early but I'm very happy with the sharpness and bokeh from the lens for portraits. I did the "wall" test too and this Sigma zoom looks great to my eyes all the way to the corners at every focal length, with a very slight softening at the extreme edges wide open. I'll do some landscapes this weekend to see how it fares at smaller apertures. All the shots below were wide open at f2.8 with defaults in Lightroom and some small adjustments but with default sharpening.
A few more. This time you can thank my sick daughter who agreed to a couple pictures even though she's feeling terrible too. I'll try and shoot more at 35mm. Most of the portraits were done at 50 and 70mm, with one below at 24mm.
