On Otus Readings: the Zeiss 85 F1.4 Otus Comparison article (205 comments in total)

Thats funny, I thought canon would be the one to get the most out of this sensor, the d810 looks much better with the OTUS and the Canon just a hair better, this acctualy proves that the 85 from canon is sharper than the nikon one and the dilutes even more the diference between these 2 sensors.

RXIV worse image quality than RXIII?
OR now we are getting real RAWs?
The chromatic aberration and of the RXIV and a little diference in white balance is very perceptible.

Mike FL: Rishi Sanyal;

Regarding to your statement of "Actually, our results are entirely comparable between cameras despite us not reporting measured vs. manufacturer ISO because for any given ISO, we always give cameras the same exact exposure and amount of light.".

Really? Lets selecting RAW and ISO=200 in DPR's "studio test scene comparison tools":

- Nikon D4: F5.6, 1/100s

- Fuji X-A1: F5.6, 1/60s

Will you still say " for any given ISO, we always give cameras the same exact exposure and amount of light."?

YES?

Well you just proved what he said...
The fuji cheat on ISO numbers...

On Canon PowerShot G3 X: What you need to know article (561 comments in total)

600mm is kind of a niche.
I guess pana with 400 is a better compromise.
I still prefer the rx10 2 over the other 2 but the price have to go down.

chrispicasso: Just buy the sony a7R II.??

HowaboutRAW, take your time to explore this new sony camera and notice every new nuance of detail on the spec sheet, and we can discuss. And by the way the new shutter mecanism was totaly remade from the ground. As this guy said.

In reply to:

Marcelobtp: I guess Dpreview made a error stating that ISO 102.400 can be used in video mode. Please confirm that.

Thats why i guessed they were wrong, but they said that Sony said, so who am i to say that it doesn't.

In reply to:

Marcelobtp: This camera is acctualy capable of more than 8k video, Its just amazing! HOLY COW!

This camera is full sensor readout. 8k is about 33 MPX this has 42 so yes greater than 8k.

ZeneticX: Everything is perfect regarding this camera but there's 3 minor issues for me:

i) The RAW engine. Previous rumours are stating sony is working on a revised RAW engine for this camera, but there's nothing from the official press release. Only reviews can tell now. Not that a big issue for me compared to some out there, but it's good if they can solve the issue to bring in more professional crowd.

ii) Where's the II sign in the logo?

iii) DAT PRICE

as for lenses, Sony had promised an additional 8 FF E mount lenses by end of this year in a separate announcement weeks ago. Surprised that isn't covered by DPR.

cmon, they could have included usb 3 or 3.1. For a 42mpx and 4k video recorder this is a must.

In reply to:

vincent__l: Interesting engineering approach from Sony. Full frame sensors don't gain as much, for low light performance, from BSI compared to smaller sensors. However, the BSI sensor likely allowed Sony to use much wider (thus faster) metal routing for the pixel interconnect. This greatly improves the readout speed which is important for both video and liveview performance. The faster speed also allowed them to have silent shooting with such a large and high resolution sensor. I'm curious to see the impact on color accuracy due to the BSI approach as there may be some degradation. There may also be an impact to battery life and noise from the higher readout speed. I'm also curious as to what caused the additional weight vs the A7II.

the EVF is bigger: one cause.

prossi: Now can you imagine what the a7s II is going to be?
Night vision camera with upped rez, 4K and image stabilization. Can't wait.

Nope?
What he said is totaly reasonable, he didnt said nothing about resolution, 12 mpx is plenty for 4k.

4k for 5 min, at least sony extracted what was possible from the camera no hack need for it.

GREAT!
Almost all images are great in high level!

On Nikon D7200 Review preview (525 comments in total)
In reply to:

Marcelobtp: Would like to know, D7200 still have the same problem from d7000 and d7100 that i had to calibrate all of my lenses because all of them were having too much AF errors, and still have, very unreliable af points from the far left and far right?
Seriously, i don't know if the nikon AF was always like this and now with higher resolution we see how problematic it is (Not a problem on my d700 with any lens) Or they lowered too much the quality control of their cameras and lenses.

@sunkenbranch Thanks, thats is what i was expecting. My d700 have a hardtime to missfocus, in very rare cases it misses it, my D7100 misses too much in comparison. and my zooms when i correct for one end of the zoom, the other end never get perfect focus, on my 18-105 and on my 24-70 2.8.

I have some Lucky friends then, because no one of them had similar problemas with canon cameras, but with d7000 and d7100 almost all had. This is weird. And i all of my lenses were like 10 to 18 points descalibrated. Seems to much for two consecutive generations. How unlucky i and some friends are. Thanks for your response Rishi
