Ruy Penalva: It seems that in drawing is better because this photo does not show anything resembling an atom core and electrons spinning around it.

Rosember: Perhaps a soccer ball!!! Such a thing is to resemble a ball, other thing is to be a ball. The electron layers are clearly separate from the core, otherwise they could merge and form an indistinct element. But we are talking of angstronic measures that are not visible by material means available. If we cannot say a position and velocity of a lepton at the same time (got it?) how we could see it immobile? The photo fail to show the measure of the ball took for grant as being a single atom. What was shown to the public lacks too much information. If the great Hadron Collider do not shown us an atom selfie how can this isolate research take a photo of it? Something to English man see and believe. If this were true he is a strong candidate to Nobel Prize.

It could be good to women know what their husbands are doing, and vice versa. Does he have inertial navigation? Only few countries have this technology.

Rosember: You decided to change all atom conception? He shot a tiny ball that seems big in the space of two millimeter of the trap and manage to register an image regarded as a single heavy weight atom. Are he right? What he shot is really a true atom image? I doubt. Seriously I doubt that an atom can be shown in a true photographic image. What smart pixels has his camera! Remember the dual behavior of the electron that in a single observation is wave or particle. Rosember Ignobil Prize! You are not Heisenberg.

It's shame! USA abuse of espionage around the world. Promotes state coups. Invade sovereign nations but are worried of an innocent cell phone! Chinese routers are already prohibited there. How they explain Russia could elect Trump that is not a real man but a Putin avatar teletransported to White House?

Barney Britton: Chiefly by a thing that has nothing to do with photography, and is poor explained and poor detailed. It is not possible, classically, to shot a sole atom. So I'm very surprised by that non-photo of an atom. Now I'm waiting for a Quark photo. Was you impressed?

Nokishita is a secure source. This will be a great addition to 14-24mm lineup.

This photo of yellow rose with an unfocused background seems to be mine.

May be it will be worth to glasses or to some laser weapons.

It is a bad and unintelligent choose, since better was to choose a79 that really was a breakthrough in mirrorless market, and use this battery!

I know a7RIII should be a great camera, but Times is only selling merchandising.

Ruy Penalva: You post this rumor with a lag of almost one week!

The rumors are the expected use in such cameras, not the patent. Canon has a lot of patents that never become reality. I read this news in Canon Rumor a week ago!

In reply to:

Ruy Penalva: Please! Clarify. How do you made a review with a camera that will be available for consumer only in November 30th? Is your camera a market finished version? All in all, you gave it a score above Nikon 850 even with its "star eaten" allegedly restriction. How do you compare it to Nikon 850? How many stops of shaking compensation has it at the telephoto (above 200mm) range? Is it fair to evaluate shaking at 50mm?

Dear friends above. You didn't understand me. No, I'm not a Nikon user. I'm a Canon user, and I have a Sony a9 ready to use. My question about shaking is that I consider to measure shaking at 50mm unfair. By the other hand, we know that only sensor stabilization is not enough when it comes to long focal length, except to in mgrum unique experience. So, is useless to measure stabilization at 50mm, because rarely we need stabilization at this focal range. Calm down! I only questioned some aspects of the review and the so called "star eaten black hole" effect at long exposure, above 4 seconds, in arii and a7riii. I know the wise men above do not agree with me!
