The thing that could shake up their DFD is if they got a processor speed that pushed it to a level of focus tracking that rivaled Phase detection. I've thought about this for several years now. Processor speeds have risen for all manufacturers. And after all, Panasonic is an electronic giant. Not out of the question. The thing I really did like about the S1 I tried out, with their 24-105 f4 lens, was the sharpness was pretty unbeatable. The noise was very very low and oh those colors. I was impressed with color rendition and still am. Panasonic has a decent color science to be sure. If they came up with an advanced G10 to follow the G9 offering upper scale professional stills functionality I have to admit my B&H account would be very tempted. Hard to imagine it trumping the OM-1....Show more →
The only real "problem" with DFD is that there is a visible AF "wobble" when you're trying to record the EVF display for your YouTube channel. Certain reviewers (their site has the same initials as "dog poo review") harped on and on about this, without ever seeming to mention that it never affected the actual photography.

ROFLMAO good one molson. Gee I would never be able to guess who dog poo review is. They certainly are those level of reviews, and yet the followers there (most of whom are tinkerers or about as far from educated photographers as you can get) argue with me all the time. They love to bring up some absurd technical reasons why this or that. Love to argue all day long about artifacts and junk. But yeah the so called "wobble". I saw very little of it as I'm not a video person. And when you're tracking a moving subject while the subject didn't always seem to be perfectly in focus the whole time, strangely enough the resulting image was in focus and sharp. Hmm maybe Panny needs to up the speed of their EVF or something as well. I'm not going to count Panny out of the game for stills yet. But at this time they do certainly seem to be more in love with keeping the video folks happy.

I'd read that post of yours carefully. You sound like the very people you are disparaging.

The wobble is a real thing, but only because video is recording the actual focussing method (of course). We have a 4-camera all-Panasonic live-to-disk studio for our video recordings, and the wobble has not been a problem for us, at all. And the user would not even notice this movement when shooting stills, I believe.
Faster processors will improve the DFD approach, I'm sure. I have held off from getting a G9, only because we have our house listed, and these are uncertain times. If it's the last Panasonic stills-oriented camera, that will be a pity (I think its shape and ergonomics are more attractive than the G5-G6 series cameras).

The DFD wobble always catches hell from reviewers but they never seem to realize that it doesn't affect the photos. The G9 and later Lumix cameras all DFD calculate 240 time every second, that is more than most PDAF systems do. That doesn't mean the DFD system is superior to PDAF as it faces other challenges but I for one have been very happy with it in most situations. The only time I have trouble with it is in VERY low light where PDAF is much better.

I'm using my G9 for video all the time, and the "wobble" is, at least in my experience, a non-issue.

What is their rate of sampling?
The best sports/action camera on the planet (Sony A1) samples at "only" 120 times per second. Most other high-performance cameras are 60 times per second or less.

Molson had a good reply for the Sony A1, I believe Sony stated 60 frames per second for the A9 when it was released. I would "guess" (Can't find any info) the Z9 is also at 120 frames per second.
Now, don't get me wrong, I'm not saying it's all about sampling rate or that Panasonics DFD can challenge PDAF for birds in flight for example.
But I do still believe in the system. DFD in particular has a lot of things going for it thanks to the information between the camera and lens where the camera knows if somethings is in focus by knowing what each lens' out of focus areas look like. Sampling it all at 240fps right now is very fast. With more processing power in the future maybe they can double it again within a few years. All new types of technology is usually worse of than the old technology in the beginning.
And like I said, I have tried and or used for longer times, a number of different cameras. The G9 and my S1R have been the fastest in S-AF out of all of them, even with Olympus lenses on the G9 it easily beat the E-M1 Mk II in those days. I haven't used the OM1 so I haven't got a clue how that compares.

I use the G9 and S5 for video and while you can adjust certain settings for specific situations and still achieve good results, I must admit that it does become an issue. I've had moments where subjects are completely still and seated and the camera decides to pulse during an interview. I still do get what I need typically but there are just times where it's frustrating and when you start to use other systems like Sony you begin to appreciate how easy it is. You don't need to fiddle with speed and sensitivity, it just works.

To be fair, the G9 is getting close to 5 years old, and this issue is something Sony has only solved in their most recent cameras (and the problem was exacerbated with many of the Sony lenses due to their significant focus breathing).

Do we know what the sample rate is for the OM1?
Unfortunately no, been trying to find info about it but no luck.
Also, the OM1 is, if I am not mistaking, alone with their type of quad cross PDAF sensor types all over the sensor, how much this improves AF over other brands I have no idea as software also has a lot to do with things.
If I were to guess on AF sampling rate it would be 60 fps simply because Olympus (now OM) seem to have a history of always being a little "behind" in actual technology but far in front of new ways to think and how to utilize that technology (older CPU's, older EVF's and displays etc).

Hi Rasmus. Good to see you posting again. The readout speed guess that I have seen is 125 per sec. The OM-1 can shoot at 120 fps without AF, so we know that it is at least 120 per sec. This is still slower than a 50 MP A1 but twice as fast as the EM1III. But, if you are not shooting really fast action the G9 is - even though it is getting long in the tooth - a great camera with many features. Since I have an A1, m43 is a travel/street camera for me. I don't care so much about the readout speed.
