The a7rii has 5D3 af speed never mind the a7riii. (Talking about locking focus not tracking, not sure if you meant tracking or not)

I meant tracking speed and accuracy.

I have to admit, I’m holding out on this too. I am a fairly recent convert to mirrorless having shot Canon for the last 15 years, my last being the 5d3 which I loved but just got tired of lugging a big camera around on family days out. So my plan originally was to get a 7D2 as a wildlife sports camera in the new year. However having spent the last 4 months with the Rii, I am totally sold on the Sony system. The only thing I miss is the tracking (however I have been using a Sig 120-300 Sport with MC11), which is a bit hit & miss. If the Riii is significantly better then I miss upgrade, if not then I think I will give the 100-400 GM a try instead.

Yeah it will be interesting to see how the riii performs in that regard. The a9 is great by all accounts but no one really knows how close the riii will be to that level of performance yet. I don’t shoot sports or BIF so the change from 5D3 to rii wasn’t an issue for me.

A7rii's focus acquisition is often slow when the lens is defocused by quite a bit and needs larger adjustments and in low light. I purposely tried the 100-400 out and the acquisition speed was noticeable faster. Also, eye focus will re acquire the eye more quickly...tested this pretty thoroughly with the Sony rep.

A big improvement to me is how quickly the mkIII wakes up. It wakes up and is ready to shoot pretty much immediately, whereas with the a7rII you have time wait a second or two and it means you miss shots. In the middle of shooting a wedding right now and yeah it's annoying.

In terms of tracking...I didn't really get to test it out, though on paper I don't think it will be any better. That said I think the a7rII tracks just fine for most things...with every camera since the a7rII, I basically stay in AF-C because the tracking system is so critically accurate. Never did that on the 5DIII. Wake up times and focus acquisition speed thing is a bigger deal IMO.

First shoot using the Sony a7RIII, and the 24-105 in case you didn't see it

I think your problem is the adapter. MC11 + sigma lens = poor tracking, however, metabones +sigma = good tracking.

Seems counter intuitive, but that's my experience on both adapters.

Thanks Charlie, I may have to bite the bullet on the MB and give it a try. For some naive reason I expected the Sigma to be the best option for Sigma global lenses. Having said all this I’ve been toying with the Sigma for the 100-400 GM to get better af comparability (AF Lock-on, Zone and Eye AF don’t work on the Sigma)and also reduce weight. The Sigma is such a sharp lens though

I wish the A7RIII have mRAW option. I do weddings and it's going to be PIA. I'm waiting for Sony A7III and see if I can use adapted Canon/Sigma/Tamron lens to it before making the switch.

Coming from the 1DxII, I can’t wait to hold this little baby in my hands. Or should I say hand? Lol.

I ordered it with the 24-105. I was never great at focusing and recomposing. Now it seems with eye focus I won’t have to be.

But the wait to get it is killing me.

So, here's a question, and the answer may wind up being one of personal preference, but I'll ask for guidance purposes.

One thing I'm thinking I may not like is the fact there is no knob on the left top of the body as there is on the A9.

Where are the controls on the A7R3 that the A9 accomplishes with that left top dial?

You custom define them in the FN menu, works fine. The menu is similar to Q menu of Canon, but advantage is you can access in the EVF while shooting.

Would be nice to have the wheel for sure, but in practice, I typically park on set settings. Hardly ever an issue.

So that top dial controls the fps/shooting mode, and AF mode. AF tracking is so accurate on the a7 bodies that most people stay in af-c mode, so the only thing missing is fps. All of the buttons and wheels are customizable, so you can either map one of the wheels to toggle the shooting mode, or map a button to turn on the shooting mode toggle.

appreciate the replies. Now the wait.......

There's also new youtube videos on the A7R3, one by the camera store. I only recently found them. They are from Canada. Very good quality videos. They went with Sony to Sedona, AZ, on a hot air balloon, etc.
