Give it insane specs and decent price and it will be hard to ignore for anybody that has MFT lenses. HFR 6K and 4K modes. Something crazy like 6K120p or internal NDs. If they add PDAF in there then for sure it will be a huge hit. MFT or S35 sensor whatever gets the job done and still has IBIS or IBIS alternative (gyrobased digital stabilization or something better). A Panasonic GH6 which is: a GH5S with IBIS + eND + 4K 120fps 10bit internal + raw output would be enough to set the world on fire. Quote Link to comment Share on other sites More sharing options...

The only major benefit I've seen is banding in LOG profiles in 1080p. On my Olympus, I never see it in 4k.Am I missing something?

So, can I have some perspective? If pushing an image 100% is doing something crazy like changing all reds to greens (with clean results), 50% is adding 2 LUTs, 25% is adding 1 LUT and some color correction, 10% is color correction only, and 0% is out-of-camera results. Where is 8 bit, 10 bit, and RAW? Quote Link to comment Share on other sites More sharing options...

Thanks for the revert. I am guessing it was an artificial (software) limitation, pehaps due to the Sony Sensor Purchase Agreement. Either PDAF or good video, not both. So PDAF.

Problem is that the "H" in "GH" is from "Hybrid", AFAIK. Albeit focused in video, the tradition it is that it would be a good stills camera too. That's why they derived it with the S. Maybe they keep the tradition and make the GH6 with the 41mp sensor with 8k30 or 8k60, and your GH5s above to clash with the A7SIII. It would be a good solution - the question is if Panasonic really wants to invest to develop two models. Quote Link to comment Share on other sites More sharing options...

If this is true, it's a sad state of affaires. Personally, I doubt they'd impose that sort of thing- a highly monopolistic move. And why would Sony say it's fine for Fuji, Nikon, and Canon? Would they actually be THAT scared of MFT? I think Panasonic has invested too much in their contrast system that they can't turn back. How much does it cost to the customer to put PDAF on a sensor anyway? 100 Euros? I'd pay it! What are they doing? Quote Link to comment Share on other sites More sharing options...

What are they doing? Well said. PDAF or Laser+ToF autofocus can't be that expensive. Unless Sony is afraid the PDAF is going to destroy their market dominance, so it can not be acquired, regardless.

I think they’ve invested so much in DfD because they have no other good alternative. DfD doesn’t require any technology licensing from Sony Semi Conductor for on chip phase photosites or any other hardware based thing. It’s purely image processing from ground up. I think with the S5 if you look at direct comparisons to the S1 and S1H they have actually done a remarkable job at reducing the pulsing side effect of a contrast based system. The tracking algorithms are much improved too. So I think it has been a evolution of a “we have no choice” to “with DfD we can make contrast based autofocus workable” to “with new object recognition and 3D object estimation and DfD we might have one of the best systems someday”. There is nothing stoping Panasonic from developing algorithms that mimic what the hardware based PDAF photosites are doing (that is using trigonometry to measure distance from subject) by building a depth map from image data and tracking objects in the space and reducing the need to do the contrast pulse to figure out what direction and how far to focus. I really don’t think Panasonic would ignore the hordes of their users asking for PDAF or something similar for years now. Quote Link to comment Share on other sites More sharing options...

I've heard about DFD tech forever...incremental upgrades..."now it's a viable option"... blah...blah...blah...except it isn't PDAF and doesn't work nearly as well FOR VIDEO. For photography, it's great! I'll tell you this: if the GH6 doesn't have PDAF, we'll really know about the intentions of Panasonic to let go of MFT or not. It's THE spec that EVERYONE is going to care about, regardless how good they make DFD or repackage it and call it something else. No one is listening anymore IMO. Just pay the piper and pass it on to the customer. Quote Link to comment Share on other sites More sharing options...

Just pay the piper and pass it on to the customer. DfD in the GH6 won't tell us anything about Panasonic's plans for M43 because DfD is what they're moving forward with in both systems. The auto focus in S35 mode on the S5 looks quite promising/usable. I'm wondering if we'll get even better performance on a smaller sensor, since it requires even less processing? Fingers crossed.

Tim Sewell Posted September 19, 2020 Share Posted September 19, 2020 I think Canon and Fuji make their own sensors don’t they? And the DPAF on Canon cameras is all their own work (and still much better than Sony’s). maxmizer 1 Quote Link to comment Share on other sites More sharing options...

I can’t! The fact that every single camera they release people say its great but I want PDAF and Panasonic just ignores their feedback? They have lost tens of millions of dollars because their cameras AF can’t keep up. I don’t believe they are stupid or stubborn anymore. They are pretty responsive to their customers. So I’m more inclined to believe their is some kind of license restriction or something blocking them for paying the money to have PDAF on their sensors. And its not like it isn’t available on the MFT sensors. Olympus had it and they shared a sensor in the latest generation of cameras. 7 hours ago, Tim Sewell said: I think Canon and Fuji make their own sensors don’t they? And the DPAF on Canon cameras is all their own work (and still much better than Sony’s). Canon designs and manufactures their own sensors I believe. Fuji has some design but they use Sony Semi and their technology in their sensors so it’s not a all Fuji. The whole patented X-Trans layout etc... I honestly think Sony has caught up and is on par with Canon’s DPAF now. Sony definitely has an advantage in lowlight and high ISO focusing as well. If that matters to you. It doesn’t for me, as I don’t film in at midnight lol. Quote Link to comment Share on other sites More sharing options...

So I’m more included to believe that Panasonic is in the same boat as Leica and that they “don’t have PDAF available to them” so they built upon contrast based system. I’m not sure there are other ways to do focus except with lasers, or IR, or ultrasonic projection and apparently Panasonic doesn’t like those methods. It’s a mystery and would make a great “industry investigative story” documentary. hoodlum and maxmizer 2 Quote Link to comment Share on other sites More sharing options...

I'm going to say this is pure speculation and I don't think Panasonic deserves a "pass" on not including PDAF, other than (maybe) they didn't pay Sony for some sort of "right" to put phase detect points on the back of the sensor. And your theory wouldn't hold up if you consider Olympus who had PDAF in all modes. Sure, Olympus is a older player, but still. If there is truth to any to your theory, Sony sounds like a predatory monopoly. I wouldn't go to Sony Pictures to pitch your documentary idea.

The fact that we don’t know why is strange in itself, don’t you think? Olympus is an old player, perhaps they had their finger in the pie and hence had some grandfathered in PDAF use license...who knows. And just to be clear, I’m not giving Panasonic a pass on DfD. I want more reliable autofocus. PDAF would give it to them right now so I am advocating they do that to fix their AF woes and camera sales. Now, if Olympus or JIP could somehow get 10-bit in their camera with their pleasing color science and partner with Panasonic to get good codec and video processing and a proper LOG format then they would have something compelling. They have the lenses. They have PDAF. They have good SooC color. They have the weather sealing and body design. They don’t have good menus (complete shite imo). They have lots of ingredients. Someone just needs to back the pie. John Matthews 1 Quote Link to comment Share on other sites More sharing options...

This might be wishful thinking, but you're right. Not much needs to be done for Olympus to kick ass in MFT (sorry, watching too much Cobra Kai!). I will say, about their menus, the super control panel is the best thing since sliced bread. Decent slow-mo and internal, editable, 10-bit should be a top priority. Finally, they simply need to tweak their face detection to work at a greater distance from the subject. With all the rest being the same, it would be a winner! Again, ain't nobody goin to buy that GH6 with PDAF IMO. There are just too many other options at the same price-point. I'd rather run a two-camera setup with Blackmagic 4k and a Sigma quatro, or something there the likes. dellfonic 1 Quote Link to comment Share on other sites More sharing options...
