On Nikon D4 & D800: What do the Professionals Think? article (391 comments in total)
In reply to:

Taikonaut: According to Nikon Rumour poll survey most Nikon owners prefer the D800 to have smaller 16mp like the D4 that doesnt compromise ISO and fps rather than 36mp with lower ISO and slower fps.

D700 is still today a good choice, I think.
I have one and the only lack is: frequent accidental displacement of the focus mode selector.

Well done, DPReview!
Interesting points of view!
Interesting Andy Sheppard' interview: D700, Jpeg and.. no pp, I hope.

In reply to:

tlinn: Excuse me if this is an obvious question but does a 4/3 sensor really lose two stops worth of DOF compared to a so-called full frame sensor? So it would take an f/2 lens on a 4/3 sensor to achieve roughly the same look as a full frame f/4? I knew there would be a reduction in low light IQ due to smaller pixel size but I never thought about the effect on DOF when migrating to a smaller camera.

On a 10" large print Circle of Confusion value is 0,2mm
(CoC is the larger blur spot that you still perceive as a point).

With a FF (36x24mm sensor) you must enlarge the image 7x to have a 10" large print;
on the sensor CoC=0,2/7=0,028mm.

With a 4/3 (17,3x13mm sensor) you must enlarge the image 14x to have a 10" large print;
on the sensor CoC=0,2/14=0,014mm.

Then a FF has a DoF greater than a 4/3 camera.

Allright, Olympus... better come up with a nickname...

Or: "Olim-5".

PicOne: So.. Nikon's answer to the G12.. and basic conclusion is that it competes very well.. yet Canon got a Gold Award? from the conclusion..

"On the plus side, the P7100 is a more versatile video camera than the Canon PowerShot G12, which lacks either AF or optical zoom during video capture.
In other respects the P7100 stacks up very well against the G12. As far as their handling is concerned, the cameras offer similar but not identical experiences. We like the G12's fully articulated LCD screen and its dedicated ISO sensitivity control but the P7100's quick control dial is useful too, and we prefer the more DSLR-like design of its two command dials as well as the slightly longer reach of its optical zoom. Ultimately neither camera is unequivocally 'better' than the other overall, and crucially, their image quality is extremely similar (and very good)."

@Revenant: ok, the categories are different.
You should define exactly a few categories where put cameras inside. Scores would be referred to an exact category. You should up to date actual cameras scores at least yearly, inserting scores in a database where you could see all the scores (IQ, ...) of the actual cameras of the category.
So readers could choice the category and then could value actual cameras scores. Not an easy project!

I agree.
Lumix GH2 (79% sc. : Silver Award)
while Canon G12 (73% sc. : Gold Award) and
Sony A65 (78% sc. : Gold Award).
Why?

Sdaniella: Coolpix P series live view... like D800... D700... or any Coolpix... no thx.
all one can do is preview 'framing/focus'... with a neutral autogain view... which is unrelated to exposure settings.

if Nikon offers 'exposure simulation live preview', like D3/D3x/D3s... maybe D4... then, i'll consider it... but since they leave out the most advanced ExpSim or ES-LV features, then interest is zero.

in the meantime...
PowerShot G/SX/S/A series w/ M modes... ALL OFFER exposure simulation live preview... (a normal feature), in PowerShot G1 to G12, and G1X... as well as 1DsMkIII/5DMkII, 1DMkIII/IV, 1DX, 7D/60D, 600D/550D, etc, etc...

Sony's offer it in their prosumer digicams... too...

so, this leaves Nikon LV in the same company as Fujifilm and Kodak... maybe even Pentax too... and prosumer Olympus and Panasonic (the latter gets it 'part-time' on LX series, but that's it)

You can add live histogram graphs, live depth of field, live indication of overexposed areas of the image.
But, I think, in Still Life only.
Can you adjust exposure in bad lighting conditions, in the field, better than a TTL automatic exposure can do?

An enthusiast could tolerate a bigger and heavier camera and take a Nikon D3100.

GX1 can be your best camera if you needn't a viewfinder.
I'm waiting for similar improvement (hight ISO results) on the GH2.

In reply to:

chadley_chad: Stick a J1 sized sensor in and you'd sell millions - but as it is, its just another high priced, low quality P&S with a long and slow lens. Yeh, it could have a place in your collection, but you'd never take it out on its own (and cry at the results!)

26x Fuji X-S1 has a 2/3" CMOS sensor.

"The 75mm lens is a higher-end portrait lens than the existing 45mm F1.8 "

But the 45mm F1.8 is very good portrait lens with pleasant bokeh!
It's important the minimum allowable distance too for better general use.

In reply to:

h0tsauce: wow high iso samples of the D800 can be found here.

http://cmphotography.com/blog.cfm

I've seen: very very good samples.
But I don't know how a D700 could give worse results with same author, same lens (85/1.4G), same lights, same ISO and same pp.
Surely face recognition can help but I would see a direct comparison D700 vs D800 at same conditions.

In reply to:

Thudd: Typical, that with the D800E they *remove* something, and charge more.

(yes, I know it's not quite as simple as that, but still)

Nikon D800E has an infrared absorption filter and "two" low-pass filters to maintain the same focal plane.
A different project could be cheapier but, in my opinion, with problems in order to achieve the interchangeability with existing Nikon lens.

In reply to:

Yomama: To be honest, The short flange focal distance of the nex is what makes it so difficult for them to produce decent fixed primes that are not bigger/longer then it needs . It's pure physics, small body (with short FD)=bigger lenses (NEX), normal body (with normal FD)=normal lenses (Fuji & Samsung), and big body (with long FD)=small lenses (Pentax).

The market is longing for faster pancake lenses with high IQ..... Sony will have a hard time doing so. M43 seems to be hitting the sweet spot with the size of the body and collection of lenses. I also think Pentax K-01 will do a lot better than we think.

Please do the math of adding up the lenses length of Sony's 16mm (23mm), 24mm (66mm) & 50mm (62mm) and compare to Pentax's 21mm (25mm), 40mm (15mm), 70mm Ltd (26mm)........ Ouch Sony. Ouch

If you consider a complete camera's system with wide-angle and super-tele (for birdwatching) can you decide wich Flange Focal Distance versus Sensor's Diagonal is better in order to have a light and however good quality system?
On my advise Nikon 1 system can be, because it has a big sensor (versus 1/2.3" sensor or 2/3" sensor) with a 15.86 mm Diagonal and a big Flange Focal Distance (17 mm).
What do you think?

The flange focal distance of the Nikon 1 series is 17 mm.
The sensor is 13.2 x 8.8 mm.
Very good, im my opinion, for a compact lens system.
The flange focal distance of the 4/3 system is 38.67 better than micro 4/3 (19.25 mm).
