What, can Panasonic NOT make a PDAF sensor? They can't make a BSI sensor, so guess not.

While you’re here, what exactly don’t you like, or wanted to see changed in regards to Panasonics AF? What were you not happy with?BINGO!
If someone is affiliated with, sponsored by, or is/was an employee of any company, their opinion on their products is suspect.Congratulation Panasonic! With this action we all learn that the worth of the infos of any ambassador is nothing anymore ...... if an ambassador does not say what the company want he will be fired - great job done Panasonic!

Just in case you (or anyone else) are interested in seeing the difference without having to download his files, here's a quick screen grab showing an (over)enlarged section from the centre of each test shot:Predictably you are seeing more detail from the 60mp sensor. If you were to compare a correctly shot 80mp hires image with the 300mm f4, you'd see order restored to the universe, and the prime lens showing more detail than the zoom.He's comparing them by pixel peeping both at 1:1 magnification, where the higher megapixel A7R4 Sony file is effectively more highly enlarged. I'm comparing them at the same viewing size, i.e. upscaling the Olympus file to match the Sony image.Hmm? Daniel found the Olympus prime is sharper than either, which makes sense. It'd be surprising if that weren't the case.
'without a doubt, the sharpest lens of the bunch was the Olympus 300mm F/4. Shooting it with the 1.4X teleconverter showed almost no degradation in image quality and was still very, very sharp edge to edge.'
Do that and there's clearly more detail in the centre of the image from the A7R4 + 200-600mm than there is from 20mp m4/3 + Olympus 300mm f/4.
It is pretty neat that with the Sony setup, you can get a larger, more detailed image with regular shooting than the Oly + 300mm f4, for a similar price. Hope to see these appearing out in the wild. Yet another valid option for the birders.

Obviously it's the Sony on the left and the Olympus on the right. To me that's quite a big difference, especially if the Olympus is technically a sharper lens.
That illustrates the benefit of more pixels when it comes to capturing detail. It would certainly be interesting to see if that advantage disappears/reverses when using a 24mp Sony, or indeed high-res mode on the Olympus.

And good for him. That kind of person makes the best kind of ambassador, because you can trust their opinion. I wish him well on whatever comes next.As a general point, it illustrates that we should be aware of the pressures on these 'ambassadors' when we analyse their opinions. Notice that he said they cancelled his contract. Too many here seem to think that 'ambassadors' are doing it out of the goodness of their hearts. This gentleman seems to have a backbone.because he criticized their focus implementation DfD (Depth from Defocus) especially the continuous focus for BIF and other fast moving subjects. He would like it to be changed to Phase Detection AF.

Because he is a bitter old man. And because he has no idea what brand ambassador really is.Wow. Why so much harsh words?Why is there so much interest in these brand prostitutes who sell their endorsements of this or that brand to the highest bidder?
The brand whore must say only good things about the brands gear. That is his assignment. He was just a tool in the hands of a pimp, to sell in this case Panasonic camera gear to unsuspecting camera buyers.
Not surprising he got the push when he stepped out of line.
It will be fun when we see him in bed with his latest punter, bad mouthing his old Panasonic gear.
I guess he is dashing off Emails to all and sundry asking if "they are looking for company"

You're right, his reference to sex workers is somewhat awry. From what we've established here, 'ambassadors' are more akin to pimps.Because he is a bitter old man.

I very much doubt that it will. There are all kinds of problem with TOF for photographic rangefinding. It's very, very unlikely to give better results than PDAF. It might in some specialist indoor movie situations, but for the bulk of photography it would be next to useless.Rumor is they are experimenting with TOF which gives results far better than PDAF.
Internet girlfriend reviews. Now there's a thing.I think cameras and lenses are very similar to motorcycles. You can read as many reviews as you like, watch as many videos as possible, take them for short test rides, but NOTHING compares to actually owning and living with them for a year or so. You could probably add girlfriends in there as well. Internet reviews etc are really only useful for winning e-peen measuring contests.Me too.I'm too busy taking pics to look at brand ambassador videos. The AF on my G9 works fine btw.Why is there so much interest in these brand prostitutes who sell their endorsements of this or that brand to the highest bidder?

I try to find some impartial opinions of gear I want to buy.
Isn't that how Facebook started?Internet girlfriend reviews. Now there's a thing.
Probably as close as quite a number of camera geeks will get to the real thing.Internet girlfriend reviews. Now there's a thing.
Which is why brand ambassadors and all that nonsense should be taken with a pinch of salt. I argue the PD/DfD case as I see fit. I can say what I like because I buy the stuff I review and have nothing to lose by saying what I think.because he criticized their focus implementation DfD (Depth from Defocus) especially the continuous focus for BIF and other fast moving subjects. He would like it to be changed to Phase Detection AF.

Sounds worth having a look. I assume it is more common to downsample 20+mp images than it is to upsample. Certainly wouldn't upsample an image to compare lenses.
