p.1 #1 · p.1 #1 · 5DsR vs 5D3 vs 5D2 ISO test

Hello all,

As an 'amateur' I like to do tests before buying a camera. Here is my unscientific 5DsR vs 5D3 vs 5D2 high ISO test. It may be interesting read for some.

All images: LR CC treatment NR and sharpening / masking as needed (not the same for each)
5DsR: downsampled to 5760 px, ISO25600 was shot at 12800 -1 stop, then corrected in LR +1
5D3, 5D2: no resizing

You be the judge on better noise and contrast. These are 100% crops so not what the client sees, just for comparison.

Looks very similar to me (ignoring some highlight difference in the upper left corner). Interesting test, but somehow not surprising test results for me since the sensors rely on very similar technology from the 5D MkII.

Downsizing has done the 5DSR no favours at all.

Thankfully it's probably not something you would usually do because if you did the benefits of the 50 meg sensor don't amount to much

Interesting results. I'd expect more of an advantage from the downrezzed 5Dsr.

Since you've already made the photos, mind doing the reverse and uprezzing the 5D2 and 5D3 so we can see what to expect when we're actually resolution limited?

Together we'd see more or less the full spectrum of advantage.

What were you trying to see, and what are your conclusions? What is the practical value of this? Sorry I don't quite see what the point is. It shows that when the resolution is standardized to the lowest resolution camera the images are pretty well the same with the 5ds being marginally more contrasty. Not sure why this is surprising(?)

Appreciate the work and time put in here.

For me, real world use is what matters.
Take an image that is 1, 2, 3 stops under exposed.
The ISO would be 3200 or 4000.
Use a human subject with areas of blacks/shadows.

How can this happen in real life.... shooting a reception at a wedding.... OCF are on manual.
The B&G do something really cool and you want to capture it.
The B&G are not on the dance floor but off on the side and at a distance where there is limited light.

the 5DmkIII and 5Ds/R are closer together and the 5DmkII falls apart pretty quickly.

Thanks for the comparison. Its pretty much what I'd expect. I shoot a lot of medium format and 50mp+ on those sensors have a different effect as not only is the file larger but the pixels are larger. I also shoot a 5DSr and a 1DX. I'm reminded of the differences between the formats every time I'm at my desk working. The other big difference is DR. Sony sensors seem to be the only one trying to get blood from a rock. Generally MF produces better dynamic range.

Rabbitmountain:

Thanks for the tests. At a glance, this visually corroborates a lot of what has been bandied about for months. Which is: with each iteration of the 5 series, Canon has made successive marginal improvements. Even at 25,600 the 5DS-R detail holds up better than the others. The 5DIII holds its own pretty well to 12,800; 5DII is definitely lagging. In "reach-limited" scenarios I would think the 5DS-R would fare even better. I still have both a 5DII and a 5DIII. They still serve me just fine.

True after the 5D MkII. But there was a good jump in improvement between 5D and 5D MkII with the new FF sensor at the time. That's why the 5D MkII is still seen as the most successful 5D camera product because Canon was leading in FF sensor technology at this time. Just that they implemented the old AF system of the 5D into the 5D MkII to avoid in-house completion with the 1Ds series which used the same sensor as in the 5D MkII.

In canon land nothing beats 1DX Hi ISO range, 6D is the second after 1DX and most FF low iso have the same noise level. This is why I keep shooting old canon bodies for my low iso application. http://www.photonstophotos.net/Charts/RN_ADU.htm

I agree with your point mostly .....
The 5DmkII change the landscape of photography due to the addition of video.
This caught Canon and the creative world completely by surprise.
Entire new vertical industries have been created or expanded because of this camera.

Studios would not even think about using a 5D body style for "B" roll and definitely not "A" roll.
Covering different event with DSLR video ... to the masses.

Hello everyone,

Thank you for having a look and sharing your thoughts. A quick response from me:
1. Upon reviewing my post I noticed that the screen shots were double the intended size, as a consequence of retina screen grab. This is not good as the images are pixelated so I fixed it by resizing to 50%. The images have now been swapped, see OP.

2. For my own work, I am mostly interested in detail and contrast performance, not noise. Therefore I used highest level of NR on the 5D2, mid level on the 5D3 and lowest on the 5DsR. The resulting comparison primarily shows more or less equal noise amounts but the 5DsR holds contrast and sharpness up to 25600 very well and that is why I think it's the winner.

3. Some ask why I did this test. Well I don't have the intention to keep several different 5D bodies for different purposes. I had picked up a new 5D3 but I found good use for the 50mp for about half of my shooting. This involves studio work and big prints and landscape. The other half is weddings and events. So this camera - to me - serves more than one purpose and I wanted to see if it could do both.

There are definitely some minor issues like buffer clearing (and lag time before reviewing after shooting multiple images) and post processing load on my computer but adding everything together I found it worth to make the switch.

If there are more like me who try to make up their mind between a 5D3 and 5DsR then at least for high ISO performance they can rest assured that there is no reason to prefer the 5D3 over the 5DsR.

I sold both my 5D3s when the 5DSR came out and used them both for weddings. I recently sold one of them and now carry a 1DX_II with a 24-70 or 35 F1.4 and a 5DSR with a Canon 70-200, Sigma 24-105 or a Tamron 85 1.8 VC

You cannot beat the rich files of the 5DSR, unless you go with a Sony A7Rii, but the combo works very well together - the 1DX_II captures the 60-70% - the 5DSR captures the 30%-40% and as many of the posed portraits as possible.

Since you are a 5DSR owner, I would highly recommend the Sigma 24-105 F4 OS as the best overall lens and the new Tamron 85, shot at F2-F2.8, as the best 5DSR portrait lens - both work very well, handheld, on the camera, at very reasonable shutter speeds.

Hi Paul, thanks for your input

I am still planning to get either a used 1dx or a new 1dx2 to go along with the 5DsR. I will take some time to get used to the 5DsR and see how the used prices develop and how people comment on the 1Dx2.
As for lenses, I own the 85L so the Tamron 85 is not for me. I also own the 24-105L which was always perfect on my 5Dclassic and still OK on my 5DsR for web size or small prints but not for large. I will keep your suggestion in mind. There is also the 24-70/4 but tbh I'm done spending for a while after 100-400ii, 1.4xiii, 16-35/4IS and 5DsR, all in the last 2 months...
