    I was glad to see all the AF points are available with adapted EF lenses but I was a bit dismayed at the view finder blackout issue.

    I was curious why they didn't demo the electronic shutter.

    Also despite using an adapter + 500mm EF lens + 2X TC the birds they were trying to image were very small in the frame so I didn't feel like it was a really good demo.

    The eye AF with perched birds did seem surprisingly good but that was not really my prime interest in this camera since my current kit does very well with BOAS.

    The battery life seems awfully short too ... not up to driving the big lenses with IS and IBIS together perhaps?

    I wonder if Tony didnít give her a fully charged battery or if she took 1,000 shots in an hour. This is something to watch, but Iíve heard others reporting better than expected battery life considering the CIPA rating.

    Plus, wasnít that a MK 1 500???

    And it's not like they were smoothly panning on a tripod or monopod, following a BIF's glide path. The image was bouncing around everywhere. There's no way any predictive autofocus could assist with that. If anything it's impressive how well if working in that situation.

    This is an interesting way of comparing the R5 sensor with many others .....

    Interesting comment in the description about the dramatic drop in frame rate when tracking subjects, especially with a long lens. Is this an inherent problem with mirrorless, since focus is achieved from the sensor?

    I was wondering the same thing....perhaps so but I have not read anything from Sony users about that being an issue.

    I think in many cases 12 fps will be adequate but I am very interested to see what the electronic shutter can do for flight images....it perhaps could vary with subject distance as well as the lens and/or use of teleconverters in terms of slowing focus acquisition so the frame rate then suffers too.

    Only theorizing of course .... hope to find out all these things for myself soon

    I was also surprised at the low light performance.

    Rolling shutter when using electronic shutter might cause issues for flight images.

    For sure, 12 fps is adequate, but this will always be your peak speed and in reality you're almost never going to get this. It's sort of like salary versus take-home pay... there are always deductions. Lens aperture, ISO, shutter speed, and focusing requirements all impact the actual frame rate you'll see in real use. I note they were seeing between 5-8 fps depending on what lens they were using. I would not be surprised with the 8 fps rate in real-life use, but 5 fps is just way too much of a hit and I hope that is just an anomaly here.
