Hej mikey2000,

About the "quality of individual frames"?

I remembered from the brochure about extracting stills from video, also from 4K and saved as 8 megapixel!

So in the manual it is mentioned "Photo Capture" (page 185 in PDF) that lets you capture a chosen scene in a movie and save it as a still image.
It this works with a "Slow or Quick Movie" it would be nice.

Good luck with your tests.

That idea has been bouncing around, but I don't think it's an actual statement from Sony.

The documentation says that dedicated PDAF operates alone and without OSPDAF in some situations, and OSPDAF operates alone and without dedicated PDAF in some situations. Accuracy of one vs. the other is not mentioned. Also, both types have micro AF adjustment settings.

Well , as lhkjacky wrote , he asked Sony and they kept quite about it .

I guess the only way we'll really know is when someone with an a99ii takes the mirror out and see's what happens .

I think that is how the A99 AF-D work.

But A99mk2, you can use the OSPDAF point outside the area of the off sensor PDAF unit directly. Technically, the OSPDAF should works without the translucent mirror.

Of cause, we won't know until someone test it

5. EVF view seems much bigger than A99 and A77ii but I can see all of it clearly (I wear glasses).

The A99 deep eyecup prevents me from getting close enough with glasses. I replaced it with an older flatter one with a notch cut in the top to allow flash to be mounted.     

On the 99M2 is your assessment above with the eyecup on?

If so:
Does the 99M2 eyecup mounted on 99 allow adequate VF access with glasses?
Does the 99M2 eyecup mounted on 99 allow clearance to mount a flash?

I haven't tried swapping eye ups between the a99 and a99ii.   I will try later on.

I always wear glasses and haven't had a problem with eye relief - my glasses are quite sturdy so I can press quite hard...

For the flash, the a99ii shoe is further forward on the body. The a99 only caused a problem with my cheapo radio trigger that couldn't slide all the way into the shoe (because of the MIS front bar over the contacts). No longer an issue with the a99ii with that extra forward displaced shoe. No more forehead dents!

What do you get instead? I don't have access to that codec.

Now you will know: I just removed the mirror and the camera focusses nicely without the mirror. I used the Sony Zeiss 24-70mm f2.8 to test.

Yikes that's huge. Thanks for that info.

Here's another request for testing AEL.

-Set any custom button to AEL toggle.

-In any exposure mode, even M, engage AEL toggle, and it should lock the exposure value.

-Take a photo and play back for review.

-Then press shutter half way and return to shooting mode.

Did the AEL toggle hold the reading?

I ask because... a900/99/77/700 will lose the AEL toggle after playback. You have to set it again. But a7RII will retain the AEL toggle even after playback.

I use AEL toggle all the time to lock in an exposure value. it's even handy in Manual exposure because it keeps the relation between aperture and shutter speed to the same EV. Very handy. But it stinks to lose the reading just because playback was used to check exposure.

I've used AEL toggle since Maxxum 9000, 9xi, 9. But of course they didn't lose the setting after playback because they didn't have playback. They would hold the reading until camera turned off. The old Olympus OM-4 would hold the reading even after camera turned off. But would lose the reading with every lens change.

Also, it would be interesting to see if video AF works with mirror removed, and if the aperture limitations are set free, as they are with a7RII.

Would also be interested in knowing if mirrorless AF works with screw drive lenses.

Sorry to put all these questions to you. Enjoy the fate of early adopters...

No, surprisingly only stills.

Yes, but obviously only with those, that support Hybrid-AF. I tried the old Sony 50mm f1,4 and it worked, while Minolta 100mm f2.0 didn't work / AF moved but did not stop.

Guess: Video AF with no mirror won't work.

Why? In video mode, only the conventional PDAF points show up.


It's interesting the AF works without the mirror though. (I suspected it would, for supported lenses).    

How easy is it to remove the mirror? It might be useful for astrophotography...

You can get an idea of how mirrorless video AF would work (if Sony allowed it to) by removing the mirror and walking around with the camera in AF-C still mode with the shutter half-pressed. Video AF would probably be intentionally slowed down, though, as it is with dedicated PDAF.
