Re: Patent: 50-300mm f/4.5-5.6 DO for EF-S & EF-M
My bad
My time as a reviewer has taught me that there are a LOT of unsubstantiated opinions that float around camera communities but are repeated as fact. I understand, though, as few photographers get a chance to actually use a lot of the gear and are forced to rely on the "experiences" of others.
I get to handle most of the new gear that comes out and I still get things wrong sometimes.

Well, if you're going to base your opinion on actual experience instead of personal bias, go right ahead.

Where in the world of focusing without a mirror has Canon delivered? "The technology has not delivered" is far from equivalent to "The technology cannot deliver".
When they want to play in the pack of performance leaders in Mirrorless, the technology certainly will allow it. The idea that a company with 4 bodies released compared to 17-23 bodies for most of the competition is trailing because the technology can't deliver on the goods isn't based in reality.
A decade of watching Canon one-up Nikon in just a couple of performance specifications while happily trailing in others should tell you where they plan to be. That was in a market where their releases mirrored the frequency of the competition. Now we're talking about a market where the release cycle is between 20-25% of the frequency of other players.

Hi Dustin, video may be. But I don't care at all for video, i have never and will never capture a minute of moving images. Not my ballgame. All I am interested in is AF performance for stills photography. And from all tests I see, Sony A6000 and A6300 and A7 II series are ahead in AF performance - both one-shot and tracking moving subjects - compared to the latest and presumably greatest Canon DP-AF implementation (80D in liveView mode).
Yes, I do believe that DP-AF *theoretically* is a very promising concept. In Canon cameras however, it has not delivered anywhere close to this potential. Whether Canon is not able or not willing - can be debated (me thinks not able). But who cares? All I do care about is: "does Canon have it, yes or no? If no, then i don't buy from Canon". As simple as that. Have not bought much from Canon over the last 3 years. Their problem. Not mine.

EOS M and full set of EF-M lenses. It's my city travel kit. And my mountaineering kit. And my skiing kit. And my family events (in daylight) kit. EOS M + 22/2.0 is my coat pocket always on camera. Did not upgrade to M2 / M3 because they are no worthwhile products to me. Always hoping for a "killer M4". beacuse I like the UI and i like those compact, cheap and optically decent EF-M lenses.
5D III i and L lenses .. only for planned shootings. Dont drag it along with me any longer. Too big, too heavy, too conspicuos. Too many places where mirrorslpappers are forbidden.

What was the last item you bought and what do you shoot with? What do you use it for?
Just curiosity as to why you're interested in the M platform. I have my reasons, which for me it makes sense to continue with the M3 + EF-M lineup and wait for the M4, begs the question does it make sense for you?
I'd argue Canon makes a solid product, but, it's not for everyone.

I saw a similar claim on Youtube, but nothing to substantiate it.
Do you have other links?
On the other hand, I have read horror stories of poor in-factory QA of Sony/Zeiss lenses. I am not willing to go through this kind of pain.

Re: Patent: 50-300mm f/4.5-5.6 DO for EF-S & EF-M
sorry, got no links to Canon DP-AF (80D) vs Hybrid CD-PD AF (Sony) on hand. need to dig 'em out.
re. Sony lenses: it's the sole reason I have not switched to A7 II series or to A6000/63000.
Latest horror story - use of GLUE to hold essential parts of Sony lenses together until it fails - to be seen here: (FACT, not fiction): https://www.lensrentals.com/blog/2016/04/a-look-at-electromagnetic-focusing/
including rather expensive lenses like FE 24-70/4 and FE 55/1.8 .. Zeiss-badge does not help here ... ouch! :

Re: Patent: 50-300mm f/4.5-5.6 DO for EF-S & EF-M
I found something here: https://www.youtube.com/watch?v=VoNRXWFTFa4
From the 13:03 mark, a comparison between 80D live-view AF and 6300 AF was made. According to the reviewer, both cameras were EQUALLY impressive in terms of functionality, but given the ease of use of the 80D touchscreen, the advantage goes to the 80D. Of course, if single eye AF is desired, then only the A6300 has that capability.

thanks!
Sony is handicapped mainly due to lack of touchscreen. Totally irrational crippling of their product.
Other than it shows, that Canon DP-AF does not deliver anywhere near to its "full hype potential" ... so far, Canon could not utilize the theoretical advantage to deliver products with better or massively better LiveView AF performance compared to other brands with "regular" hybrid CD + on-sensor-PD AF system.

Oh, I see. First, 'everything you read' said Sony was better than DPAF, and you were going to 'dig out the links' to support that claim. Now, when someone else provides evidence to refute your claim, you agree with it, but Canon still fails in your mind because of 'hyped potential'. What it shows is your own bias. If Canon built a MILC custom-made just PERFECT for YOUR EVERY NEED, you still would find reasons to criticize it. Keep on slapping your mirror. :

Re: Patent: 50-300mm f/4.5-5.6 DO for EF-S & EF-M
... then i would buy it. And it would not take much. Basically 5D IV capabilities (sans video stuff) with good EVF and 500+ battery charge ... in size, shape and weight like a Sony A7. Plus a native, fully functional Canon EF-X/EF adapter instead of some metabone-or-whatever-third-party-stuff.
Re. DP-AF performance: nothing is refuted. According to that single linked video "evidence", AF performance of the latest Canon DP-AF implementation (80D) seems to be close to but not 100% of Sony A6300 (with regular hybrid AF). Canon just gets a nice mentioning, due to touchscreen. And yes, Sony was stupid to not put one in their cameras. But definitely nothing to sing the praises of "ever so innovative" Canon DP-AF.
PS: in a Canon mirrorslpaper DP-AF is largely wasted anyways, as it it only useful in LiveView and mainly for video.
