I know it is very early in the life cycle of the new A9, but curious if anyone has actually been able to try the new Sony A9 with a canon 500/600mm prime lens, using an adapter of course, in the field for wildlife or BIF. If so, I'm curious of your thoughts on how the AF performs in a real world situation, and which adapter you used.

Adapters have not yet been updated for the a9...too early

This is the only video I have so far seen, not exactly tiny wildlife but the AF looks pretty snappy!

Well that looks promising. Like you say, will have to wait for some tests of tiny passerines flitting around in the branches of a tree. It did appear that the shift from the nose of the plane back to the helo showed some potential.

Currently there are issues with the MC11 and Sony A9. Sigma is working on a firmware update.

Good to know. Like many, I am intrigued with many features the A9 presents. I have been mostly happy with my A7rII for landscape work. As my 1DX is getting long in the tooth, I am on the sidelines pondering a replacement. I am aware that the A9 may not have the same dynamic range as the 1DX II (however pretty close), but the quiet operation, the smaller profile and a few more pixels on subject are all intriguing. With that said, those who own the 1DX II I know, rave about its AF capabilities claiming better than 1Dx. And for the kind of stuff I go after, improved AF with my 600mm is pretty high on my list of wants. So it will be interesting to see the field use reports (versus "lab" results) play out.

Having just come back from Slovenia where the bears can be completely spooked by shutter noise this camera would be a revelation!

I have tried my 200-400 and 400DO with both the Sigma and Metabones.  Not ready for prime time IMO.  I hope it is an adapter firmware update.

On another note, it is a very impressive camera.  I haven't shot any birds down here in Florida yet, but have images of my dog running, grandson in soccer and hockey and granddaughter in her dance recital.  Most shot with the Sony 70-200 f/2.8 Gmaster.  The auto focus was incredible for all the moving subjects.

Here are a few posts if you are interested:  http://www.mojphoto.com/p154737205  The dog images were all at 400mm.

If they get some longer glass it will be a serious competitor in wildlife photography.

Mike-which Metabones adapter? I have the IV but have thought about the V

Rocky,
Neither one works for me

Seems continuous AF is limited to 5fps with a converted lens. Not sure if this would also be in single point mode (does A9 do single point mode?)

I have A6500 and a Sony A9 in conjunction with the MC11. With the A6500 + long lenses no real issues but with the A9 there are well known compatibility issues
The MC11 needs a firmware update to work with the A9 and apparently Sigma is working on it. I use the Sigma Sports 150-600 and AF only works in AFC upto 500mm, after that AF is all over the place. Same with the 100-400 Sigma

DP review posted a test by Dan Watson of Learning Cameras using the A9 with Canon 300mm and 400mm lenses. Tested with the MC-11 and Metabones IV. The test wasn't a wildlife use field test so many caveats remain. None the less, the lenses didn't play all that well with the A9. Its always possible (probable?)  that  the third party adapter manufacturers will be able to improve the adapters so they play better with Canon glass...or Sony likely working on big glass themselves. Which of course will present a whole host of interesting "discussion". A topic that is still in its youth.

A bit too much hype and pushing of the A9 as a "game changer" on the preliminary reviews in my taste. Though there are some interesting innovative features such as the silent shooting, no mirror black out etc,  I think they have a long way to go to compete with Nikon and Canon for serious pros:

I.e:

- no long glass yet and AF options limited and inconsistent  with Canon glass, see https://www.youtube.com/watch?v=5TSCjUlQsjE
- Praised frame rate of 20 f/sec drops to 12 f/sec with uncompressed raws
- Buffer clearance lasts 2-3 minutes which puts the high frame rate in perspective
- Weather sealing and resistance at least questionable compared to the D5/1DX II
- Ergonomics - i.e. hand grip not suitable for larger hands without additional grip
- Sony still lacks a serious pro service net compared to CPS or NPS - very important for pros....etc.....

I do think in regards to weather sealing, a flippy screen cannot be as weathersealed as a fixed one. I am sure this is why they have not found there way on to pro bodies yet... that and the chance they could be broken more easily.
Tests with the latest Sony SD cards cleared the buffer faster than 2-3 minutes I believe there was some IAE (internet amplification effect) going on.

But once longer Sony glass is available it will be a different show. Eye focus for flying eagles would be nice :) I can live with 12fps and 12bit files as I hardly use 8fps on the 1dx. I do wish Canon would give the option of compressed/uncompressed.

Why would you want uncompressed files??? Especially since Canon's compression is lossless.
All comments & suggestions welcomed and appreciated.

For what it is worth. I have since a week a Sony A9 and A6500.
i use 2 Sigma MC11 adapters with the latest firmware on both. The 2 Sigma lenses I use are: Sigma 100-400 and Sigma 150-600 Sport. The Sigma 100-400 works fine on BOTH cameras. The Sigma 150-600 works well on both cameras upto 500mm! Over 500mm in any AF setting it hunts like crazy. Strangely the further away from closest focussing distance it works ok over 500mm upto 600mm but the closer you get to closest focus the more erratic it gets on both cameras. So to me it seems that a firmware update is not only needed to address the A9 but also for the A6500. I also have, at home, the new Tamron G2 150-600 with the Sony LA EA3 adapter. It limits the AF settings but it works fine on both cameras. The Tamron is nice, more compact and lightweight but I feel the Sigma might be the better lens and maybe it is worthwhile sticking with the Sigma and wait for the firmware update. Is there anyone using the A9 with MC11 and Sigma 120-300 with or without converters? Preferably on latest firmware? Sony has a Pro service nowadays and lack of long lenses is an issue fir sure but if the MC11 does what it needs to do, I would be more then happy to stick with the Sigma lenses. The camera needs a grip, which I have, is super fast and I love the silent shutter

It was tested with the latest Sony SD cards, see https://www.youtube.com/watch?v=wv7ZVSnEtmA  at min 3.0 ff and is said to be even much worse if you back up the files on the second (slower) SD card slot.

In fact, HQ longer class will be mandatory. But even then they also need to build up a reliable and competent global support net for pros comparable to CPS and NPS which takes years of experience. Once the technological hype on the A9 has slowed down we will see if the electronic giant is able and willing to compete here, too.

Yeh CPS rocks, three day turnaround or a loaner. :)

https://www.youtube.com/watch?time_cont ... wpKTmNFg3U In this test 200+ RAWs emptied to the card in 25seconds. If you need more than 200 RAWs in a burst something is amiss ;) and the camera was operational while the buffer emptied.
