Frank_BR: It looks like DPR is making a mountain out of a molehill. The ultra-professional Nikon D5 which costs $ 6500 has dynamic range more or less equal to the Canon 6D Mark II for ISO below 1600. Check out here:

How about this DPR headline:

"$6500 Nikon's flagship D5 dynamic range falls behind modern APS-C cameras"

Isn't it very objective, too?

It's like a 100m sprint race. One of the competitors (Sony) has already reached 50m, but a latecomer (Nikon) has not even started. Go Bolt Nikon, go! You can still win the race!

Is it raw or JPEG?

In the eagerness to innovate, Canon just missed the point. The correct name for this "revolutionary" new model should be EOS 6D Mark I.I, not EOS 6D Mark II.

The best UWA lens (this 12-24mm); the best sports camera (A9), and "world-first all-rounder camera capable of both high resolution and 12 fps burst shooting with AF" (A99 II). Hat-trick by Sony.

A9 is the seventh full-frame mirrorless Sony camera since the announcement of the Sony A7 in October 2013. Sony's progress since then has been spectacular. Compared with the achievements of Sony, the innovations brought by Canon in this period are almost insignificant.

Why would Sony have a hard time launching fast super-telephoto lenses to complete their line of professional lenses for the A7 / A9 cameras? Designing high performance 300, 400, 600 mm lenses is a capability that more than a dozen lens manufacturers have held for decades. The difficulty today is to design a camera with the characteristics of the A9. Designing a 300 or 400 mm F2.8 lens that can focus quickly, any Sigma or Tamron can do. So, do not be surprised if Sony launches one of these lenses long before many people imagine it.

Frank_BR: If production of DSLR cameras sinks, it means that Canon will not be a viable third-party lens supplier for Sony, unlike Zeiss, another failed camera manufacturer in the past, but that manufactures lenses for Sony today.

Canon will likely always be number 1 in the shrinking market of DSLR cameras. Just like Leica is still the number 1 in sales of rangefinder cameras.

What is the point of this "experiment"? It's a technical Tour de Force so pointless as using a cannon to kill a mosquito.

Rick Knepper: So, according to the title of the article, the theme is "undercooked". I wanted to find out what "undercooked" means but the article never uses the term again. I searched both the article and review and nada.

I think they meant that at the time the PowerShot SX1 IS was launched, CMOS sensor technology was not mature, or "cooked".

The idea seems promising. Nature has been using curved sensors in the eyes for millions of years.

Frank_BR: An important point that the article does not address is how the legion of photographers who firmly believe that OVF is superior to EVF will accept the DSLR-mirrorless transition. They will certainly feel betrayed and will have a hard time adapting to the mirrorless concept. Take the case of Leica, who has never been able to make a successful transition from rangefinder to SLR. Leica lost the professional market and became a niche manufacturer. Canon and Nikon may be going the same way.

"BTW, don't talk to Canon about "betrayal"."

Who betrays once, betrays twice.

On article Nikon reshuffles management structure (248 comments in total)

Nikon is needing to reshuffle its management structure because after the mirrorless technology has matured, many consumers have reshuffled their preferences.

Any questions now that mirrorless is the way to more compact and lightweight wide angle lenses? Half the weight of Sigma 12-24mm F4 DG HSM Art or Canon EF 11-24mm F4L USM. Checkmate.

"... the A7 has a lot or hype" LOL

Not just for WA primes, mister. For any WA, primes or zooms, a shorter register is better.

FE mistake? The A7 is a huge success for Sony! Are we living on the same planet?

Why has Hasselblad designed a new mount for the X1D, which is a mirrorless MF camera? Why did not Hasselblad use the H mount on the X1D camera?

What does the register have to do with grip depth or ergonomics? Nothing! The advantages of short register is for the design of lenses, especially wide-angle lenses.

Canon would be a stupid company if adopted the EF mount for its future FF mirrorless cameras.

Not so easy. Using the EF mount in a mirrorless camera would be a bad idea. Take the Sony case. Why did not Sony use the A mount in the A7 cameras? It would be so "easy" ... In reality, the A mount has a too long register for a mirrorless camera. To make viable the A7, Sony had to build a new line of lenses, which is still in progress, by the way.

The extensive line of EF lenses that today is an asset will be a burden to Canon tomorrow. When Canon launches a serious mirrorless camera, the entire EF line will become obsolete overnight, just as it did with the F-lenses. Canon's future is uncertain, you can be sure of that.

"Mirrorless will be the norm once Canon and Nikon decide it is. it won't be decided by Fuji, Sony, Olympus or Panasonic."

Hmm... Canon's and Nikon's soft landing is not so simple. Mirrorless cameras rely heavily on electronics, an area where Sony is light years ahead. Also, what will Canon and Nikon do with the extensive line of lenses they have built over time for their DSLR cameras? They will have to build a new line of lenses right from the scratch, something Sony has been doing for some time now. When Canon and Nikon jump into the mirrorless wagon, Sony will be well ahead.
