In reply to:

peevee1: The samples at 24mm f/4 don't really allow to evaluate focus precision - DoF is too deep.

@Joseph Black Thanks!

We need to see Af performance with very shallow depth of field, and long teles. For now image quality seems to be on par with the others.

Marcelobtp: This will not sell that well because too much people already both the sony rx100 series. But man, this is something!
pocketable?

I said "that well" will seel good, but not as good as it could be if it was launched with rx100 mk3
i don't think people will be selling the rx100 just for that camera, there are size and weight advantages for the rx100 and its a very, lets say above the over the price camera. And, its very very good for its purpose, i will wait a little to see what happens next but this lumix really caught my attention, and i never had a panasonic, this probably will be my first one. =)

tom1234567: Lost for words it looks a great camera to me has all the bells and whistles
a lot better than anything C & N have ever brought out
of course the fan boys will disagree

Specs wise all the bells and whistles, lets see how it will perform, and how much time the battery will take.
For an aps-c mirrorless this camera seems too big.

This 7DII should have been launched last year as people say, but what the problem?
Its a sport, wildlife photographers camera, the lack of 4k video is not that bad...
This is the best you can get in crop sensors today. Very good camera!

Oh yeah, thanks Samuel, I forgot about WRGB, but if DPR showed it i would not get confused.

"Sony, i want a 0.75 10-300 with no optical distortion please..."
Seriously people don't really know what means an f/4 in FF terms with OSS...
For a UWA zoom its very very atractive lens. For people who bought A7 series i think was looking for a trade in size to no compromise quality.
The triade is complete for most professionals 16-200 f/4 oss.

To not say that is perfect, why not usb 3.0?
And why not all the other brands put usb 3.0?
This should be standard by 2014 to 2015 announcements...

Hoho, Canon is uping in the right direction.

Its getting funny to read comments, more than the announcement.

Bamboojled: 5DIII and 6D R.I.P

7D mark II 20mpx, 65cross AF and many more features, D750 was not a killer.
But the -3EV focusing is something to take note.

In reply to:

JDThomas: This is pretty much what the D610 should have been in the first place. It's got a lot of great specs and will be a great camera for a lot of people.

However, this is not a D700 replacement. I think Nikon is trying to bury the D600 stigma by using a name that people equate with one of the best cameras Nikon ever produced.

It's relatively cheap at only $2300, but I would have paid $3000 for these guts in a D810 body.

@JDThomas Thanks.
D700 for real was marketing mistake from nikon and they probably decided to not commit the same mistake anymore, because it made D3 a lost cause. Anyway, at least they had the card up its sleeve, that was the D3S, wich was at least a revolution in terms of hi-iso.
I think that nikon missed the chance here. But it would be the same, canibalizing d810 sales. I think that even with this D750, d810 will be kind of canibilized too.

I will read it, thanks, but in advance i know that micro-lens tech will not be equal to smaller photodiodes, and will introduce some kind of distortion in the process.

The process will be similar, but is just about physics. Maybe i`m thinking that the photodiodes are rounded, and thats why they would have more space between them, so they could catch more light thats are not at 90 degrees em relation to the sensor. But supposing i`m wrong about it as you have more resolution with a smaller size you get more fine detail, and finer details are the cause of moire, because a bigger diode can`t distinguish that as good as a smaller one.

I will see the test but the reason for the mooire is that the photodiodes are bigger and has much more space between them compared to the gh4 that has 16 mpx and uses only about twelve in the center i assume, so you can`t see the same amount of moire, and thats the same reason why nikon sold the d800e, when FF get at the same pixel size of the GH4 we probably will not see any moire anymore.

In reply to:

Marcelobtp: The only thing i want to know about the d810 is dynamic range at iso 64.
It is better then a7r iso 100?
This is really a true base iso 64 with all of its vantages?

Thanks LSE.
