EOS Bodies / Re: Canon 7Dii vs Nikon D750 Dynamic Range Test
« on: November 01, 2014, 09:25:06 PM »
Thanks for the test, Michael. I'm glad you ran the test.

Given that you lifted the shadows, I think that can explain why they look brighter on the D750...there IS a lot more dynamic range to be had there. In my experience, lifting Canon shadows looks exactly like your Canon results, where as lifting A7r shadows look exactly like your D750 results.

I do think that showing the entire wedge, from the highlights to the shadows, both unprocessed as well as processed, and including the settings you used to process them, would help provide a more balanced review. It should head off the most predictable of human responses (which is quite prevalent on these forums) as well. ;P

Anyway, looking forward to seeing the full step wedge in both OOC and processed versions.

I see what you are saying here. Its black and white to me, but without showing what I am actually doing and how I am trying to get these 41 calibrated steps all in one shot, I can see how it would be confusing. Im out shooting now, Ill post something tonight to show how I am clipping off that first step in RAW, and then squeezing everything I can out of the shadows.

I know some people believe this is not useful or not a DR test, but I think the results are pretty obvious. If you have a better solution or idea, I would still love to hear it.

A Maven is an both an expert in a particular field, AND someone who is willing to share his knowledge about that field, I first learned about it from the book "Tipping Point" by Malcolm Gladwell, and it has stuck for me.

I consider myself a student of all things who is willing to learn as much as possible and then share. Whether someone considers me an expert depends on their personal perspective. I teach beginning photography, so from the students perspective in terms of learning photography, I better be an expert...right?

The 5Diii test is there as well, thats full frame to full frame.

Same strip, same exact settings on both cameras same everything. I have a hard time differentiating between stops 32/33 and higher on the Canons due to their noise. The D750 is much cleaner and easier to differentiate, more visible, distinct shades in deeper tones. Its clear to me. I try to frame up the strip edge to edge in both cameras. when I shoot it so yes the focal lengths are different. 

The strip is calibrated plus the strobe & tripod do not move, not sure how that would explain such different results between the two.

There was some exposure and shadow recovery on both, no noise reduction. Ill have to play with it more once the 7Dii files are supported by Camera RAW.

Canon DPP will only convert to tiff and JPEG files, unless I am mistaken.

Thank you for the feedback.

Sorry about not explaining more carefully, good feedback.

Yes, essentially I am looking for the total DR I can squeeze out of a RAW file but recovering in the shadows, so both files have +2.6 Exposure (the point where the first swatch overexposes) and shadow recovery all the way. Part of the problem is I cannot import the 7Dii into Camera RAW and have to use RAW Therapee which I am totally unfamiliar with.

I believe it is Apples to Oranges in some regards because it is full frame vs crop (and photo site size seems to effect noise performance), but the reason I wanted to test is because they both have the most current sensors and processors from respective companies.

Im basically trying to get as many 1/3 stops of range captured with one end (the highlights) being clipped out. There is some room for recovery there, so its limiting my ability to find total DR, but all things being equal, it allows me to get something a little more illustrative than just recovering some shadows in an image.

Thank you for the suggestion to get out and shoot. My Dad just dropped off his Tamron 150-600, Im going to take it down the to beach! Im listening to all your feedback, so thank you for that as well.


EOS Bodies / Canon 7Dii vs Nikon D750 Dynamic Range Test
« on: November 01, 2014, 08:05:26 AM »
I was happy to get my Canon 7Dii yesterday and being in the middle of reviewing the Nikon D750, I decided to put them both through a Dynamic Range test I have been working on.  I know it is an Apples to Oranges comparison, but I was curious none-the-less.

Im not a huge fan of, nor believed a certain testing website for various reasons, and have always read their scores with skepticism because their methodology is mostly proprietary and scoring system whacky. In fact, I have long wanted to come up with a DR test simply to confirm or deny their DR tests to some degree.

I am long time (12 years Canon owner and shooter vs 3.5 years of Nikon), so if anything I would naturally be more biased towards Canon, but in this test I think we are looking at a DR for the 7Dii very similar to that of the Canon 5Diii.

In the past, some of you have been very insightful with suggestions and tips to improve my tests, and therefore I invite your scrutiny and suggestions. Many others of you have ridiculed me, which also actually improved the quality of my tests, so I guess I invite that as well, as long as there is some creativity involved in the ridiculing.  :o

What do you guys think I can do to improve this beyond the obvious (cropping straight).

What would be a good way to figure out total DR and noise cut offs?

In any event enjoy!

Focusing system sounds pretty sweet.

Boggles the mind how Canon is ignoring the 4K and video features that Panasonic is winning droves of new customers with.

+1 on the lens selection issue. Sony has my attention now, but the lack of internal 4K, cost, sports focusing and lens selection make it hard to beat that $1700 price point of the GH4, which can do internal 4K. That Shogun external recorder is another $2000, Id rather have 2 voightlanders for the GH4.

The 55 1.8 was by far the best lens i tested on Sony. Id even say that might be a better first lens than the 24-70 f4, which is ok, but the 1.8 was amazing. If Sony has a wider selection of fast glass they will be a force to be dealt with. I also tried the 12mm 2.8 Zoutt, was not impressed with it (the Panasonic 7-14 on MFT was actually wider @7mm (?!?)

Been shooting with both cameras side by side for 6 weeks now. The lack of native focusing lenses, no internal 4K and the sports focusing sums up my gripes about the A7s. I was able to get some nice voightlander glass for the GH4, wow...what a difference that makes.

Thought you guys might enjoy the final review, which summarizes how they compete against each other. Im still looking for a reliable way to test DR without needing expensive software. Any suggestions or recommendations are appreciated!

Those are some great reviews you shared- thank you!

The A7S is growing on me the more I shoot with it. Did lots of sports type tests and there are a few weird things Im seeing. Definitely not a sports shooting camera, but can be used for the occasional shot if you have nothing else.

I did check out it's low light focusing ability again. Far off the charts of anything Ive ever seen or can measure with a light meter. It almost appears as if it is boosting the signal into live view and focusing off of the boosted signal. Only when I went into a very dark room with all the lights turned off did it actually start to struggle.

It is tempting to bring the 6D into the tests as the next closest competitor, the A7S is so good at low light focusing I am shocked. It has me loving it one second and being disappointed the next. Took it out for sports shooting this am. 1.5fps on servo focusing?? Really? The A7S is not a camera for sports.

Ill have to redo the ISO noise chart of the A7s vs the 5Diii (a touch out of focus), but the A7S vs GH4 Noise Chart is now up. Huge advantage to the A7s.

We resized the GH4 down to 12MB. Also, from what Ive seen, the A7s has about a 1 stop advantage over the 5Diii in higher ISOs when resized, Again Ill have the 5Diii ISO chart up soon.

I have the A7s in hand, also have a GH4 and 5Diii. I've done some initial testing and should have more show later tomorrow (July 2nd).

I have mixed feelings, but in my limited time playing around with it here are some thoughts:

- Great ISO performance, but the higher ISOs are indeed pretty grainy.
- Incredible Low Light focusing sensitivity. More than anything I have ever tested, but only with native Sony lenses.
- Im already wishing Sony had many more lenses made for it with very wide apertures
- Paired with the Metabones Speedbooster and wide aperture glass, it could be a low light monster, especially for video.
- The Metabones Adapter, (not the speed booster) AF pretty much did not work, at all. I might have a bad copy. I hear it is slower, but is still supposed to work, but I had no such success with it.

I was very impressed with the DR and colors it could see beyond my own eyes, as grainy as it was:

There will probably be a sweet spot for low light portraits, but I would imagine it is around ISO 25,600.

Ill post the ISO charts later today.

That is one thing I have already noticed about the E Mount, is that there aren't a lot of really wide aperture lenses for it, seems most of them are f4 or f2.8, only a handful of comparatively expensive 1.8s.

I have actually 2 different EF adapters I am testing, one has Autofocus, I hear it is a little slow, but I will definitely test it, I have a bunch of wide aperture Canon glass Ill put on it.

Now if only that Shogun Recorder was available....

Thank you for the input everyone- I appreciate it. I have all over you suggestions on my list.

I think the astrophotography comparison is a great idea, especially with the high ISO performance of the A7s. Ill do the low light focusing too (its rated down to -4 EV which is supposedly better than the 6D), and the noise performance tests.

Ill post any preliminary stuff here for feedback as well.

Thanks again and keep the ideas coming if you have any more

Hey guys, Im planning a comparison video between the 5Diii, A7s and GH4. I have gotten a lot of good insight from you all in the past, but I am opening this up to suggestions you might want to see?

I looked at the GH4 and have one now, it is very impressive for video work. (Like amazingly). It ran into issues with sports focusing. 

What tests would you guys like to in a match-up between these three other than the typical ones I normally do:

- ISO Noise
- Sports Shooting
- Dynamic Range
- Portrait Comparison
- Video Moire
- Etc?

  I thank you in advance!

I have a pretty good training set on both the 600EX RT, as well as the ST-E3. (this comes with a download) This is the DVD only.
