Next Patrick came out with Sony A9 and Canon EF Long Glass Compatibility for Sports Photography with the Sigma MC-11 lens adapter, so pretty much everything is covered in these three videos. Awesome job and very informative on a number of levels so be sure to fallow this guy!! [divider]
If you are interested in doing this sort of thing with your Sony A9 as a second camera or even a primary, clearly it is possible! The results look killer to me, but using the lens adapters does seem to come at a cost in responsiveness.
At the end of the day it works and it works well, but I would rather be using a native lens mounted to the camera body for sure. In situations like this if you are getting paid, you can’t really afford to be dealing with any lag whatsoever. That is not to say it can’t be done, but if your spending that amount of cash on gear, your better off going with a DSLR like the A99 II or A77 II in my opinion.
The Sony A9 drops to 10fps when using A-Mount lenses, so the Sony A99 II for example, would be a better option at 12fps and it costs over a $1300 less if your counting…. Even more important is the instant autofocus with no delay due to the lens adapter translation that must occur. Something to think about for sure and thanks again to Patrick Murphy-Racey for the awesome videos and information!
