ProfHankD: Hmm. Stacked BSI would be a HUGE fab jump for Canon to make on a FF sensor. There are methods for stacking using what's essentially a front side illuminated sensor... are we sure they're doing BSI on this?

As for the gaze tracking for AF point selection, that's really pretty easy tech... but it might be a bit harder to do with the more direct optical path typical of an EVF. There are also potential issues with people who wear glasses, etc.

Yeah, that happens.
I once searched an announcement for BS and came up with nothing...

Well, as a Prof you should read before commenting ;)

@ProfHankD
It´s in the Canon press-release, as seen here on DPR:

"At the heart of the EOS R3 camera’s performance will be an EOS camera first, a Canon-developed, full-frame stacked CMOS sensor with a back-illuminated design,"

@ProfHandD
As Canon says it is a BSI design I don´t understand why you think it might not be.

With some more deep fake you could have them read out their will.

Horrendous.

Very nice trio, just these kind of compact lenses ML needs.
Panasonic should be thrilled, these lenses make their L-mount offerings even more attractive.

On article Leica Q2 Monochrom sample gallery (104 comments in total)

I will say about subjects and composition,
but from the POV of exposure and contrast the OOC jpegs are really bad.
Looks like flrst attempt failure in the darkroom.

Why bother with photography when you can buy picture postcards with beautiful skies at any tourist location.

I´m sure they are good lenses, but they look a bit weird.
At the back, behind the control ring, they have other texture than the rest of the lens. Makes it look like they´re on TC,s.
Wonder why.

On article Panasonic Lumix DC-S5 review (942 comments in total)

L-mount looks more and more interesting.
The S5 looks like a very nice addition, and a real battery grip is key for us with big hands and long tele preference.
Taking Sigma into the equation there are about 20 top quality lenses covering 14 - 400 mm, including a macro lens. And more to come.

And for the primes lovers, Sigmas f/1,4 full range from 20 to 85 is hard to beat.

Nice.

FuhTeng: A terrific piece of glass for the people who need it or can use it. I'm thinking sports shooters.

I agree with rubank,
many pics are very "cold", but I doubt it´s the lens.
But again, there´s nothing spectacular in the IQ.

If these pictures hade been published without telling,
I would never have guessed on $10 000 lens.

In reply to:

andrewD2: The UX designer decided that ACR should work more like lightroom. A lot of ACR users hate Lightroom. We don't want the backwards crop tool. We like the tabbed interface that's easier on hand movements.
We didn't want thumbnail generation to take longer.
I've had a Photoshop licensed copy since PS6, many boxed CS updates, subscription service since it started.
Bridge 2020 is worse than Bridge 2018, the new Photoshop needed task manager to kill it but the ACR changes made me make the choice.

"We've processed your cancellation request. Your service will end on 16-June-2020 (PT)."

Agree, the new ACR UI is really annoying.
I went back to the 12.2 version, luckily I had a copy of that CameraRaw.8bi at another location.

Arca-Swiss compatibility out of box?
Of course not, this is a Nikon lens.

Not even at that price does this lens come with an Arca-Swiss compatible tripod foot.

When will they ever learn!

rubank: I would very much like to have a drone, and DJI make good ones.
But after looking at the permissions their Android apps demand, it is clear that DJI drones are not for me.

Sure, I could get another phone without any accounts, contacts, phone numbers, pictures or video, history and so on - but it´s not worth it.

I´m not about to feed the yellow monster.

Do you really believe your photage and flight paths end up on a chinese server, along with your contacts and accounts?
Well, you´re not alone . Of course they will :)

Longer, wider and heavier than Nikon´s DSLR lens. 82 mm filter vs 77 mm.
Focuses closer but offer same magnification, so more focus breathing.
Higher price.

I´m not tempted.

Super 8 with turrets? I only remember S8s with zooms.
On Double8 however, they were common (until zooms made them obsolete), and even on 16 mm cams.
How many of you remember those? :D

As a sidenote: on M43 such arrangement, with small MF lenses, could well be worth a try.

Elaka Farmor: When Fujifilm x100F was announced the equiv focal length was a obvious thing to point out. Here, not a word of the equiv focal length. Ohh, now I remember! No one cares of focal lengths. Sorry.

C:a 25 mm (FF equiv), f/2

It´s a sad state of affairs that the mfg:s go for proprietary mounts.
ML should have been the great opportunity for them to act as grown-ups and agree on an open, common mount and a common protocol.

Now they´ve blown it again, like angry children in a sand pit.
It is hard to understand that they cannot see how it would benefit them, and their customers, to have a common mount/protocol. Without customers they are nothing.
