  1. 20fps silent shooting at 24MPix and a buffer of 241 RAW and a significant lower price tag than D5/1DXii? I think Sony's done something great, at least on paper. If the reliability is also improved, this camera would be the marking of a new age and the end of DSLRs.

  2. $1200 too expensive. Would love it but not at that price, especially with the highest price lenses on the market on top of that.

  3. Sony marketing team is doing a great job! The videos of A9 are well-made, telling us the key advantages in a clear way.

  4. The new electronic shutter looks pretty cool. But I would still prefer to have Electronic Global Shutter.

  5. According to B&H photo https://www.bhphotovideo.com/c/product/1333228-REG/sony_ilce_9_b_alpha_a9_mirrorless_digital.html
    $4499 Yeah a real bargain!!
    Thanks I will 100% take a miss on this one

  6. I've been shooting with Nikon for a long time. I currently sport a Nikon D4 + 5 high-end lenses. I've been waiting to switch to mirrorless to see what Sony had lined up next, and this is it. I'm ready to switch! The one thing I wish were better on the A9 is I would have really liked to see at least 50 megapixels. I like to crop in tight and those extra MP make a difference. Anyway, not a deal breaker for me. 24mp is still great. I'm excited. Bye bye Nikon. It's been a great ride, but you haven't innovated fast enough and I must leave you… Sony here I come!

  7. There is no doubt whatsoever Sony cameras are good, and I like my a7Rii and a7Sii but they stitched up a lot of people with the a6300 then within a very short period of time brought out the a6500. Got one of those too and the touch screen sucks.
    Sony bring out stuff too fast and need to calm down, and pulling stunts like they did the other day when there was a "£500 price drop" on the a7Rii's and a7Sii's was some form of bad joke, especially for anyone who bought one at the higher price point.
    Sony are having a PR melt down right now, and pissing a lot of people off.
    This is a great shame, they are an innovative and forward thinking Company, but just need to slow down a bit.
    Too much TOO fast.

  8. OMG – WANT.

    Finally seeing some of the grander features of the A6x00 series coming up to the full frames. Can't imagine what the R and S versions will be able to do…!

  9. They got rid of the mirror and shutter. Now all we need is camera-less and have the sensor surgically implanted.

  10. If canon doesn´t convince me with their (hopefully soon) coming 6d MK2 with an usable 4k mode with c-log with the flipscreen with touchscreen with the dual pixel autofocus, I´ll seriously think swiching to sony.

  11. This is odd. It might foretell that we won't have an A9S and A9R (because this Sensor is not sensitive enough to be an 'S' and an 'R' is technologically both too far away and too expensive, especially if the 'R' would have to jump into Medium Format).

    So that bodes well for the a7r and a7s Mark III, and a fire sale for the M2's. The a7r III could be their upcoming Medium Format, and the a7s III is bound to get a puny resolution increase along with a few more Stops of ISO (and another Stop for using the new Oly IBIS).

    If only the a7s III got enough of a bump for 8K external, then they'd dominate; especially if they had a big Cine Lens Set.

  12. can i use flash when i am using electronic shutter? I use plenty of flashes in wedding photography and this could be a deal breaker.

  13. The line of photography and video recording could break when the camera is able to take 24fps. It becomes video clip without sound, & the camera becomes camcorder. That's the end of photography. Enter the video recording era.
