Sigma E mount full frame lenses will kill Sony lenses either regarding quality or regarding prices or both.

Think the chief thing is the 130 million EF/EFs lenses in the market. Canon is pursuing to make a product compatible with that legacy. Make no sense to do differently.

Yes! I will ask Mr. Putin a portion of Novichok, made in England, to give to both.

No surprise at all since Canon repeatedly said in the past it would wait such market to grow steadily before enter in it. Now Canon will let the mirror fall and get in that profitable market.

On article CP+ 2018: First Look - Sony 400mm F2.8 G Master (462 comments in total)

Make no sense to have a small camera body and a very big lens. If it were to be so better stay with DSRL body. There is no magic when it comes to lens of long focal length. The hood was not shown but it should be big too.

Got sein danke!
This 105mm is a brick! It seems to have the same hood of the 150-600 Sports, that is boring to fit and to store.

You should evaluate a battery in the long term behavior and not in a short test of energy output. How long the cheap Ikea Ladda maintains its charge while stored? How many times it can be charged and discharged? Every-time appears a Mandrake wanting to change the gravity law.

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?
