Sdaniella: as usual, dpr overexposes 6D MarkII @ ISO 100 by 1 stop ... @ 1/5s
for the given quite bright lighting scene
and
should have been 1/10s

and more in line with the ISO 6400 @ 1/640s shot

no one shoots to just an ISO setting ignoring lighting or intentions of retaining highlights to avoid clipping them

mis-applying incorrect exposure habits in ISO-Invariant cameras (actually has 1 to 2, possibly 3 actual real ISOs, who know?! no one ...) to cameras with Actual-ISOs like the 6D/6DMkII as dpr (and many others) does is misleading

post-processing has become the new "digital unblacking RAW" ritual of those stuck with ISO-invariant cameras, where pre-rigged U-shaped histograms (peaks absent in the middle) are fixed to more natural correct exposure histogram (distribution)

jared-froknow shared a9 px at a sports stadium sunny bluesky day, he had it shown as an unreal black+blown high contrasty scene with a bizarre U-histogram, so i unblacked/unblown the RAW to uncover the actual flat scene

in fact let's start with a definition of 'real ISO' and 'Actual-ISO' as i've not come across these terms in this context before.

out of interest, how are you defining these one two or three 'real ISOs'?

Scorehound_ca: I recall not too long ago the Sony a9 had one of its tests redone because of an error by DPR staff. Again, we have all these comments based on one person's use and not real world shooting in real situations.

I think it would be best to wait until real world reviews come out from photographers using retail shipped cameras.

out of interest, how will any of that change the measurable characteristics of the sensor?

I would like to assure you that both our lab and the beach you see in the sample shot are in the 'real world'. Also, we are totally transparent when it comes to correcting errors, and in 14 years have only ever had to retract a couple of test results. In this case we're 100% confident as this test doesn't require micron-level focus accuracy and everything else is fully controlled.

PedroReina: Mac-unfriendly? Simon: may be we should blame Apple when it is not up with the industry standards. I had no trouble with the Mavica.

neither did I, nor did I say I did. Serial transfer cameras on the other hand....

WastingTime: This is the first digital camera that I remember.

@DarnGoodPhotos - almost! there was a short-lived mini Zip disk format (the Clik! drive) that was used in a single camera, the Agfa ePhoto CL30 Clik

MrBrightSide: "...proves Sony can still teach the traditional camera manufacturers"
Funny that Sony still isn't considered a "traditional" camera maker even though it has long been a dominant player in cinema and broadcast cameras as well as consumer video and still cameras.

To be fair I was quoting something I wrote in 1998

AbrasiveReducer: I gotta say, I'm amazed that Sony and Amazon's lawyers okayed a video that involves igniting magnesium, in the L.A. sewer system, no less.

In reply to:

dprived prev: the review was made in 2008, only three comments (including this one) made?
and the other two comments are relatively new too: one made only a month ago, the other one 7 years after the review's original date! how come?

because we didn't have comments back then!

In reply to:

Geekapoo: DPR should spend more time with camera reviews versus iterative hype. Yes, the A9 does appear revolutionary for mirrorless..but DPR seems more focused on "click bait" than a well rounded site giving thorough reviews for cameras and lenses. Methinks it's more about hyping cameras that have the greatest potential to sell (hopefully by clicking to Amazon via DPR)

@Geekapoo If we were really trying to 'hype cameras that have the *greatest potential to sell* (hopefully by clicking to Amazon via DPR)' would we really choose to concentrate on a body that costs over $4500 and can't even be bought yet?

Yxa: Is it SONY PR day to day DPR?

yeah because manufacturers are always paying us to promote decade-old products

Irakly Shanidze: It is just too bad that nobody explained to the author that focusing with a rangefinder is faster and more reliable than AF when done right. All you have to do is to set the lens to infinity after each shot. That way, there is only one direction the focusing ring can go.

When it comes to guessing and zone focusing, the simplest and most reliable technique is positioning a standing person between horizontal frame lines and focusing on it. After that, any person of approximately the same height will be at approximately the same distance. No need to recompose.

@Irakly, as the owner of probably 30 manual focus cameras both rangefinder and SLR, i understand better than you think. But my point was simply about an autofocus SLR being faster than a rangefinder...

runbei99: Ah, the DPR staffers broke in with newfangled crap!

I started with a Kodak Instamatic in 1963 - I remember a Vopo (Volkspolizei - People's Police) border guard in East Berlin who was interested in the camera and asked me about it. His partner, who resembled Brunnhilde - she was built like a truck - sneered at the camera and exclaimed, "Japanischer Kitz!" (Japanese trash).

In 1966 I borrowed my Dad's late-1930s-vintage Zeiss Ikon folding camera, as my first "serious" venture into photography. Now use a Canon 6D (not sorry).

i assumed so too :)

none of us was alive in 1963... or 1966 for that matter :)

no one doubts a rangefinder will produce accurate focus, but do you really agree that focusing with a rangefinder is faster than AF?
