Administrators Andrew Reid Posted August 31, 2016 Administrators Share Posted August 31, 2016 "Dramatic dynamic range improvement" "Back when we were briefed by Canon about its update to one of the most popular line of digital SLRs in existence, Canon told us that dynamic range was one of the top concerns of current 5D-series owners." "A major leap forward" https://***URL removed***/news/3229755227/canon-5d-mark-iv-brings-dramatic-dynamic-range-improvements-to-the-5d-line ... So let's take a look at the reality behind the hype... Oh hey it's their own test scene... +6EV shadow recovery on a shot exposed for the highlights Samsung NX1 has it for breakfast The A7R II turns up and has it with milk and tea And the D750... 2 years old... Mentioned NOWHERE in the DPReview article, is an order of magnitude less noisy at +6EV recovery All in all meaning the 5D Mark IV has less dynamic range than the Samsung NX1. I double checked... Yeah it does. And that my friends is why in a nutshell I stopped being a writer for DPReview.

OliKMIA Posted August 31, 2016 Share Posted August 31, 2016 The first picture of the article to illustrate the increased DR comes from their review of the D810 and there is not mention of this...

OliKMIA Posted August 31, 2016 Share Posted August 31, 2016 Yes.. I knew I saw that picture before, you know trying to shop for camera with real DR The first picture is from the current "Dramatic DR improvement article" while the second is from the review D810 conclusion https://***URL removed***/reviews/nikon-d810/18 Quote Link to comment Share on other sites More sharing options...
treb999 Posted August 31, 2016 Share Posted August 31, 2016 Looks like they used a plugin like topaz adjust to give it an HDR effect too. Quote Link to comment Share on other sites More sharing options...
Luke Mason Posted August 31, 2016 Share Posted August 31, 2016 The title clearly states that "Canon 5D Mark IV brings dramatic dynamic range improvements to the 5D line” They were comparing it mostly with 5D Mark III. Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted August 31, 2016 Author Administrators Share Posted August 31, 2016 In the studio test at least, the skin tones have gone to hell on the 5D Mark IV shot in the shadows too. Which is why - for example - exposing for a window behind your actress and then pulling her out of 6 stops of dark shadows is a really really bad idea Anyone interested in designing a REAL world DR test for EOSHD?

noone Posted August 31, 2016 Share Posted August 31, 2016 To be fair, they are only saying it is a massive improvement over other Canon's. At the end, they do say this- "How does the 5D Mark IV stack up against some of its other peers? Its performance is much better than any other offering from Canon, but it's still not quite as ISO-invariant as the Nikon D810 or D750 (refer back to widget above as you click links). You're unlikely to notice these differences from ISO 400 upward, but below ISO 400, the 5D Mark IV, while competitive, does fall slightly behind in performance". I m not an apologist for DPR and think it is not so much what they have said as what they have NOT said. OliKMIA and MountneerMan 2 Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted August 31, 2016 Author Administrators Share Posted August 31, 2016 It's not a "DRAMATIC" (their words) or MASSIVE (your word) improvement though! It's tiny! The 5D Mark III has 5 year old sensor tech, is it a dramatic surprise they have managed to squeeze out half a stop more dynamic range in 2016 with the mark 4!? And the 70D has a fundamental sensor architecture / image quality that you can trace all the way back to 2009 with the original 7D and T2i So DPR hyping the 80D and 5D Mark IV dynamic range improvement is just that...

Liszon Posted September 1, 2016 Share Posted September 1, 2016 Mix the Pentax K-1 into the comparison. Half the price of the Canon. It's even cleaner than the D810 at ISO100, 1/320, +6EV. Not to mention it leaves the 5D IV in the dust. Pentax is such an underdog, I wish it would be more well known. The K5 was a fantastic machine, I loved it.

Erm 5D Mk3 100 ISO pushed 6 stops 5D Mk4 100 ISO pushed 6 stops At 6400 ISO they look about the same except the MK4 is sharper than the MK3 and the D750. While it's not ISO invariant like the Nikons, it is a huge improvement over the Mk3, and that noise isn't hard to clean up in ACR. It's almost as resolute as the D810. D750 6400 ISO 5D Mk4 6400 ISO If you need to push any DSLR video 6 stops good luck with that. Quote Link to comment Share on other sites More sharing options...

squig Posted September 1, 2016 Share Posted September 1, 2016 Noise looks to be on par with the 1DxII up to 6400 ISO. I'll wait for the DXOmark figures, but I suspect a 1-1.5 stop DR improvement over the MK3, which would make it a great upgrade should Magic Lantern eventuate. It looks like it will be much better in low light than the Mk3. 5D Mk4 ISO 800 pushed 3 stops Quote Link to comment Share on other sites More sharing options...

Jimmy Posted September 1, 2016 Share Posted September 1, 2016 If it has gone from 11.9 stops to 13.5, that's a massive improvement over it's predecessor. This seems like good news, especially if ML get on it. Phil A and Geoff CB 2 Quote Link to comment Share on other sites More sharing options...

gelaxstudio Posted September 1, 2016 Share Posted September 1, 2016 http://www.irentals.cn/ An chinese webside tested the 5D4，and measured the DR of raw is 13.19 stop（1/60 ISO100） The competitors：Sony A7R2：14.28， pentax K1：14.27，Nikon D810：14.76(iso64) Quote Link to comment Share on other sites More sharing options...
zerocool22 Posted September 1, 2016 Share Posted September 1, 2016 Aah too bad, I was hoping on at least 2 stops DR increase. Iso noise seems to have improved though, which is a good thing as the 5D III was a bit behind the A7S in low light. I was kinda hoping this was the camera to get when Magic lantern hacked it. But now even with a hack, it is not that much better then the 5D III. I will probably need to invest into a RED raven or kinefinity terra camera. As the A7S ii is not cutting it for me(codec, 8bit, color). Quote Link to comment Share on other sites More sharing options...
