WIMorrison: Must be a slow news day as the report was published more than a year ago, actually almost 18 months ago.

Actually, the source article from Quartz (whoever they are) dated Aug 15, 2016 gives an current update of events. DPR's article acknowledges the original incident happened in 2014.

Valiant Thor: If it was a Canon camera, the plane would have crashed.

I probably would have gone with "If it had been..". The more important fault of the OP is the nonsensical troll.

vscd: And when do they push the shadows by +6EV? They really use a Canon?

Maybe they know how to expose a shot.

Rick Knepper: It is surreal when photographers claim they do not want more resolution.

When I use the term "resolution", I mean "resolving detail". The rest of you seem to think resolution means "printing big".

PanoMax: One day most lenses will be made from titanium. But expect them to be expensive, really expensive.

mezastel, imagine your typical DPR member who gripes about their $119 50mm lens being too expensive and then add $20 bucks worth of titanium to the cost. There'll be plenty of weeping and gnashing of teeth.

And of course, for a beautiful portrait, they turn to what camera and incredibly sharp lens?

Dr_Jon: BTW I'm assuming it's the same sensor as the Pentax 645Z, so you can compare DR right now...

Rishi, you say you didn't participate in this exchange:

Dr. jon: BTW I'm assuming it's the same sensor as the Pentax 645Z, so you can compare DR right now...

Rishi Sanyal Yup. I'm guessing it'll be similar if not identical. A small, small advantage over the Nikon D810 at base ISO.

We have a real-world ETTR'd Raw dynamic range shootout as well, which ostensibly agrees (naturally, one would hope) with Bill Claff's PDR results.

My point being that the characterization "small, small advantage over the D810" is disingenuous. On Bill Claff's chart, there is a 3/4 stop advantage. 3/4 of a stop should be more significant when tested on a "PDR" basis, otherwise, you wouldn't running your own version.

Dr jon, I thought it would be clear that I am assimilating two different conversations about similar things. On the Canon forum, you posted a link to Claff's PDR. Here, you & Rishi are discussing results from DPR's so-called "PDR" testing at least initially where Rishi claims as you did on the Canon forum "Yup. I'm guessing it'll be similar if not identical. A small, small advantage over the Nikon D810 at base ISO." I have no dog in the hunt at ISO 2500. So, my comments are directed at anyone who believes it is a small difference on a PDR chart. On Bill Claff's chart at base ISO, the 5DsR is two stops removed from the 645z. So, are you and Rishi claiming that two stops isn't a big deal?

So, I see now where Dr Jon got his response to my post about medium format in the Canon forum.

It is my understanding the Bill Claff's PDR charts show real world DR results vs. theoretical giving more weight to a 3/4 stop difference. The difference in the 5DsR and 645z according to the chart is two stops which Dr Jon characterize as "marginally better".

What's the point of having PDR testing or using someone else's testing to prove a point if all you are going to do is abuse the results?

Only $500 more than the Pentax 645z when it was first released. Pentax has relied on its legacy lenses to fill out their lens line-up (with a few new designs released) while the Hasselblad lenses presumably are all newly designed ( and hopefully sharp across the frame wide open). The sample picks above look pretty good but I'd like to see full size images.

Rick Knepper: I am looking forward to the day a Smartphone can produce the IQ of my 5DsR and 645z so I can get back to enjoying my experiences in the moment while recording them too. :)

Sorry BigOne, I didn't see this sentence appearing in the fifth paragraph of the article before posting, "The research mostly focuses on use of a simple camera for taking snapshots, both in real-life situations like a city bus tour, and simulated scenarios." Even so, I like for snapshots to have decent IQ.

chile7236: It's a camera. Not a fraggin' wifi router. If you're upset about the technicalities of the wifi protocol and how you have to MAKE it work, sorry but pressing a mfg with legal action is kind of dramatic. I don't feel for the "plaintiff"...Nothing about my camera inventory is about wifi ...it's about photography...or rather, my attempt at it. Lack of wifi/touchscreens/video/or other doodads do nothing to detract from that experience.

You obviously do not understand the issues.

On article D500 owner formally accuses Nikon of false advertising (475 comments in total)
In reply to:

Rick Knepper: Most advertising and marketing statements are misleading but consumers are protected because of the following although they cannot, in most cases, recoup their time wasted.

The Modern Rule: Caveat Venditor

Caveat emptor was the rule for most purchases and land sales prior to the Industrial Revolution, although sellers assume much more responsibility for the integrity of their goods in the present day. People consumed far fewer goods and usually from local sources prior to the 18th Century, resulting in very few consumer protection laws (mostly limited to weights and measures).

The Modern Rule: Caveat Venditor (continued)

Today, most sales in the U.S. fall under the principle of caveat venditor, which means "let the seller beware," by which goods are covered by an implied warranty of merchantability. Unless otherwise advertised (for example, "sold as is") or negotiated with the buyer, nearly all consumer products are guaranteed to work if used for their intended purpose.

For example, a consumer who purchases a coffee grinder that lacks the power to grind coffee beans may return the product for a full refund under an implied warranty of merchantability. But if the same buyer purchased a used coffee grinder at a thrift shop marked "sold as is," returning the product later may prove difficult. While caveat emptor is no longer the rule for consumer transactions, it's important to know when the exception applies.
