I kind of liked the flat-front on the a99 mk1, since it reminded me very much of the classic 9xi but I remember it being fairly polarizing back when that body came out. It's entirely possible that they went to a more conventional look for that reason.

That is probably because it was designed for the A77m2. My Jupio grip (I know) that works perfectly fine with the A77m2 gives erratic behaviour when used with the A99m2

The official grip works perfectly with A99 II because A99 II was designed to work with it.

If anyone is feeling "slight shifts" it's not tightened all the way. There is no difference in alignment of that grip from A77 II to A99 II whatsoever. I used it extensively on both cameras.

It probably is an aesthetic decision. It looks like a cross between the A77m2 and the RX10.

Yes, Sony got a lot of flack for the original A99 body design. Has anyone not seen Kai's A99 review at DigitalRev?


Click to watch.

However, I think it's primarily because Sony got so much positive feedback about the A77 II design.

I'm not sure exactly how many of us Pros Sony reached out to for A99 II development, but when they asked me for feedback of what I wanted, I essentially asked for an A-mount flagship that performs as fast or faster than A77 II (up to 12 FPS & they delivered), asked Sony to build upon Hybrid AF-D tech they debuted on A99 (which they did greatly), and asked for cleanish/usable ISO 6400 (which they achieved as well). I actually asked for a new BSI 24 MP sensor, but said if they could get usable ISO 6400 & 12 FPS out of the 42 MP sensor I would be okay with that because it would provide greater cropping flexibility and please a wider variety of users.

I think they took our praise of A77 II literally, even squeezing the A99 II into the A77 II chassis. I'm actually cool with that as the A99 body felt larger with the grip attached than the 1DX and tough to fit into bags. IMHO the A77 II chassis is the perfect size. Not too big. Not too small.

Also, I was honestly shocked they achieved up to 12 FPS bursts out of the 42 MP sensor. I didn't really believe that would be possible when I was putting in my request.

I'm a little disappointed that Sony left off the double cross F2.8 center point used on the A99 PDAF sensor (perhaps this would interfere with the -4 EV sensitivity?), and I'm frustrated about the features they left out that should have been included: UHS-II support, USB 3.1 for faster tethering (which was also left off A9), and pixel shift shooting. If they can add pixel shift via firmware they should. I didn't even think of that when gave them feedback, but the problem is, we're going to be waiting till 2020 for a replacement, and that's a long way away!

However, I feel A99 II was a ballsy camera for Sony, as what they achieved here, high speed high res shooting, had never been done before previously. The new AF system is great, and the IQ with Sony Mark II glass in particular has been excellent across the board!

My first shoot with A99 II was a social media campaign for a major outdoor lifestyle brand and one of the images they selected was captured at ISO 25,600. Never in my life did I think I could capture an image at ISO 25,600 for a commercial shoot.

Overall, I'm very happy with A99 II!

Quite unfair. I'm not doing it "so" the cameras overheat. I'm testing because mine "do" overheat.
(I didn't start a thread with that test. I shared that test from months ago to back up my claim when questioned about it). Not setting out to slander the beloved a99II.


Testing is better than getting burned in the field again. Nothing quick about it. All the while a competitor camera shooting the entire thing in 4K actively running same temperature as a99II's. Then a99II's overheat after two minutes of 4K recording. Dozens of other tests comparing side by side to others. Nothing quick about it at all.
Always same results.

Tests are important. I need to know what I'm dealing with and discover how best to alleviate the issues, which I can now begin to predict. That's all I want, predictability. And thus I have a7RII and NX-1 for those longer running hotter days. I now know that a99II isn't the right choice for e.v.e.r.y.t.h.i.n.g I need a camera for.

Turn off 4K, turn off Remote Control, turn on Airplane mode, shoot in cooler dry climate when possible. But that still doesn't guarantee they won't give warning (as you confirmed ), or shutdown (as your friend confirmed). We're not the only ones.

I'm learning my friend. I've never had to deal with these considerations with a 9 series camera before. But I'm used to using EMount for things a991 couldn't do, like shoot 4K. So nothing has really changed for me except I get to use my AMount in higher resolution and shorter 4K clips. Other cameras provide where it can't. a99II provides where they can't.

I just did 6 minutes straight in XAVC S 4K at 24P 1/50 F1.4 ISO 100 Picture Profile 6. Not even a hint thermal issues.

I'm not going to say the issue is you as someone else already said on here, but I suspect it's a combination of things.

Comparing A99 II or A7R II to the Samsung is silly because smaller sensors generate less heat.

Also, let's not forget the A7R II had overheating issues until Sony issued a firmware fix. But here's something interesting -- if you read Sony's firmware note it says quote: "Improves 4K movie recording time when using the vertical grip (VG-C2EM) or when the APS-C/Super35mm mode is activated."

In your test, the grips were attached to both bodies.

Never in my life have I shot video out of an ILC with a grip attached because I usually have the camera mounted in a cage, on sticks or a gimbal. Having a grip attached it makes it harder to work with as a video camera IMHO.

I'm willing to bet your recording time will immediately improve by removing the grip. I don't know why the grip would impact it, but it clearly did on A7R II and both models are based the same sensor.

EDIT / UPDATE:
I just shot a full 30 minute clip with NO overheating WITH the grip attached, so the grip not the issue either. It's got to be something with your combination of settings and I posted back in your "Oveheating" thread where this belongs.

Yes, the a7RII had severe overheat issues fixed in FW. Many didn't believe it. Like the shutter shock issue, or the light leak issue, or the battery life issue. Many who didn't experience the problem insisted there must not be a problem.

The a7RII FW update reintroduced a previous problem fixed by previous update. Depending on brand, many of my aftermarket batteries started getting the "Unrecognized Battery" warning when using VG. So I don't use the grip on a7RII any longer for anything.

I've tried a99II with and without VG and found no difference. Revisit my report and clearly see pic 11 & 12 testing without grip. I've also done extensive testing with AC adapter (with and without battery) which makes things even worse for reason described previously.

I've tried a99II in both FF and Crop. The only repeatable finding I've found is that overheating can occur in both modes.

After all this testing, trying many of the suggested fixes from others, and myself, I continue to test, looking for repeatable patterns so I can bring something of value to Sony beyond simply complaining. I've been documenting everything for the past year.

Your six minute demonstration did nothing to reproduce the testing I've demonstrated. And if that's the level of effort people put into reproducing my problems, then it's no wonder my complaints are sometimes met with skepticism.

Turn on 10sec sleep, to ensure recording is more likely to begin from a cold camera.
Turn OFF Remote Control.
Turn OFF 4K until just before recording.
Turn ON Airplane mode.
Use freshly charged good genuine Sony battery.
And there is still no guarantee for full 30min session.

Things like steady shot, FF/Crop, PProfile, AF/MF, VGrip, etc, haven't made any differences that I can determine. Not saying they don't for others... But they don't for me.

If I sense that I'm being accused of demonstrating confirmation bias, then I will defend myself by beating a dead horse, every time. I will approach Sony when I have something demonstrably repeatable to present.

I think you missed my update.

I just did a full 4K 24P 30 minute clip on A99 II without any hiccups or overheating whatsoever, but I carried the conversation over to your original overheating thread where it belongs.

Yes I've answered there.
For me, that one test with the grip is not enough to claim:
"...so the grip not the issue either. It's got to be something with your combination of settings..."

A single test doesn't serve anything unless consistently repeatable. That's like saying the camera doesn't overheat because it didn't overheat.

Agreed, but there are so many variables ... both in camera settings and environment.
A900, A58, 5d, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .
