Canon 5DS DXO Score In, Nikon D750 Service Advisory In Today’s Daily Roundup

By Anthony Thurston on July 9th 2015

Welcome to our roundup series where we will hit on several gear news and rumor topics each day. This gives you a chance to get caught up on all of the day’s news and rumors in one place. Make sure to check back daily for the latest gear news, rumors and announcements.

Canon 5DS & 5DS R Tested at DXO, Lags Behind Sony Sensors


IF there is one thing that we have been waiting to see, it was the DXO testing of the Canon 5DS and 5DS R sensors. Canon said not to expect much better pixel level performance than a 7D Mark II, but we wanted to see what a third party had to say.

Well, after a long wait, DXO has finally released those test results and 5DS and 5DS R are some of the best Canon sensors yet, but they still lag far behind even Sony’s 36MP sensor found in the D800 and A7R. Not a totally surprising result, but one that will have many rethinking the 5DS/R for a Sony a7R II.

You can get the full testing information over on DXO’s website. What are your thoughts on these test results? Make sure to comment below and let us know what you think.

Nikon D750 Service Advisory


Nikon has sent out – ANOTHER – D750 service advisory, this time regarding an apparent shutter issue that can lead to ‘shading’ of your images. Not good at all.

It has come to our attention that the shutter in some Nikon D750 digital SLR cameras manufactured in October and November of 2014 does not function normally, sometimes resulting in shading of a portion of images. We have decided to take the following measures regarding this issue. We sincerely apologize for any inconvenience this issue may have caused.

If you think you may have this issue, or you just want to check, you can head on over to Nikon’s website and enter your D750’s serial number. If your camera has this issue, or could have this issue, the serial number tool will let you know and give you instructions on how to proceed.

I hate to say it, but these sort of problems seem to be happening more and more from Nikon these days. They will certainly have trouble keeping that #2 spot in the industry if these QC issues keep coming up.

What are your thoughts on this issue from Nikon? Do you agree that there seem to have been a lot of Nikon issues of late, indicating a negative trend?

    I hope when Nikon releases the next camera model they wont repeat the same mistakes .

    Sonikon fan boys shout we have better DR, canon fan boys shout it’s a specific tool for a job and at least we have better lenses. Ultimately most people will view pictures on HD / 4k screens on phones, tablets and monitors which will resolve about 8mp and don’t buy prints anywhere but ikea who have probably bought them from a stock site from a photographer who took it 10 years ago on their brilliant new 10mp semi pro camera and they will not notice half the stuff photographers go on about. Looks like a nice piece of kit good on canon for pushing the boundaries of resolution, good on sony for delivering and excellent mirror less, good on nikon realising that they can take a sony sensor and make their cameras better.

    Thank goodness my D750’s are not effected by this service advisory. I have a solid week of studio catalog work ahead.

    DXO is on the case! [Cue the local TV investigative reporter music!]

    No surprises in their results. This is what Canon implied we’d see — very small improvements. This was only supposed to be a game changer in *detail*, and if you follow DXO, you know that resolution does not play into their sensor scores.

    I appreciate DXO for collecting and reporting data, but *rendering insights on that data* is not their long suit. If I have this right, Canon has finally delivered an FF sensor good enough to compete with Nikon APS-C. (Glad we got that one sorted out. Phew.)

    Also according to these guys, not a single L lens is in the top 300 lenses they’ve tested, a 5D3 is a ‘semi-pro’ rig while a D810 is a ‘professional’ rig, and the same damn lens gets a different ranking depending on how many pixels are looking at it. (The stellar 70-200 f/2.8L IS II is ranked 1,064th of all their tested lenses, BTW.)

    Using some of their logic, just wait until they start testing lenses on the 5DS. All of sudden, wretchedly scoring lenses on lower MP bodies will surpass the performance of F mount Zeiss Otus lenses. :-P

      Their testing methods definitely favor the Nikon/Sony sensors, that is for sure.

      I just don’t see how someone would justify paying 3x more than a D7200. The dynamic range still lacks. Yeah, yeah, yeah…I know what’s going to be said “but it’s a studio camera”. Sigh.

      Regarding another D750 service advisory… ugh… I don’t even understand why they put a 1/4000s shutter in that camera anyway.

      Anthony, I actually don’t have too great a problem with their methods or their individual metrics — I just can’t stand how they roll up the aggregate value of a sensor into a single number, or how a lens’ performance is so crushingly linked to the camera you bolt it to.

      They would drop from photography public enemy #2 (only bested by those a-holes who hold their cell phone up for entire rock concerts) to a much lower concern of mine if they just reported test data and walked away.

      But a lens IS related to the camera it’s bolted to.. it has everything to do with it. Every sensor will will produce a different images from the same lens. Glass that looks great on a 10mp sensor might look like fuzzy crap on a 50mp sensor, it may not be built to resolve the image at high enough detail (particularly at larger apertures). I wouldn’t be surprised at all if many Canon “L” lenses lack the resolving power for 50mp, they weren’t exactly designed for such a thing.

      Stephen, don’t misunderstand me, measuring the lens + body combination’s performance is a great thing and I welcome that data. But DXO brews up some epically shady Kool Aid by stating how that *combo* performed *as the ranking for that lens by itself*. That is terribly, woefully misleading. The best L lenses made are ranked worse than 1000th in DXO’s database because Canon didn’t have a 36 MP sensor until now. C’mon.

      (Now that there is a 50 MP body, if DXO is consistent with their methods, CAnon’s best lenses that only rated a ‘fair’ (20-25 score before) will shoot to the top 10% of DXO’s ratings now. The *same damn lenses* will go from ordinary to extraordinary in their ratings just because there are now more pixels sitting behind the rear element. How nuts is that?!)

      As for what glass is up to snuff, there are two answers. At a high level, virtually all lenses will render higher imatest scores with more pixels. What remains to be seen is *how much* those scores improve and *where in the frame* they improve.

      Digging a little deeper into this, Roger’s recent 5DS vs. 5DSr vs. 5D3 testing ( showed that 3 great lenses and one ancient beat up lens got a nice 20-30% improvement in the center of the frame, but only the great lenses got anywhere near that in the corners. My guess is that:

      1) Ancient 25+ year old lenses (with some exceptions) will need to upgraded. They’ll get a small bump but you’ll wonder why you ponied up for all those pixels.

      2) ‘Solid but not best’ lenses will see a nice bump in the center and some corner improvement. You got what you paid for here.

      3) Great recent lenses (Zeiss Otus, Sigma Art, the Canon 24-70 and 70-200 f/2.8 lenses should crush things in testing.

      So I don’t think it will be a black or white ‘good enough or not good enough’ distinction. In my collection of 8 lenses, only one would warrant an near-term upgrade, the venerable EF 50 f/1.4 referenced in Roger’s article.
