Canon EOS 70D review gains test scene samples

We’re working towards completing our review of the Canon EOS 70D and have been shooting our test scene with a production camera. We’ve published the test shots, including downloadable Raw files of both the daylight and low light scene. The EOS 70D review will also be one of the few chances to see our outgoing test scene and our new, more challenging, more informative scene alongside one another. Click through to see how it performs.

Now we have a production-standard EOS 70D we’ll be forging ahead to get the review completed as soon as we can. In the meantime, here’s a chance to see in close detail and in challenging lighting, how Canon’s Dual AF Pixel sensor behaves.

The comparison choices are too limited. The 6D should be in the list.


would rather prefer it’s done slowly carefully first,
than a great volume of work done in the wrong way.


yet another good (but bulky) DSLR from Canon.
Taking ocasion I am trying to attract your attention to the Oly E-M1 latest machine and want you to see that the high ISO OF LATEST M4/3 SENSOR IS RIGHT ON PAIR WITH THE BEST DSLR LIKE THIS ONE.


lol, this bulky DSLR from Canon will sell 10-15x more than the Oly EM1 … has Oly ever made a profit from m43?? no.

All the more reason to bring attention to it.


It remains to be seen if Oly still plays with its ISO ratings to deliver this result.

If the exposure value (ie the amount of light reaching the sensor) has to be twice as much as other cameras for a given ISO, then it’s not really a performance but more likely that you should compare ISO 6400 from Oly to ISO 3200 of other manufacturers.


These comparisons does not seem fair as the exposure differs between cameras. For example look at this option:

Canon 5D Mark III and Olympus E-M1
ISO 25600

The exposure parameters are:
Canon – 1/60, f7.1
Olympus – 1/50, f5.6

In the comparison EM-1 has similar noise to 5D under all sizes(full/print/web). The amount of light received by the camera sensors must have been different between the cameras to get this result.

yeah i noticed that dpreview is not very good at making things equal for all tested cameras a long time ago.

i wonder why they don´t test all canons at f16 or f22 and nikons at f8.


Or ISO 25600 is not equal for some camera makers

hippo84 – Olympus is not very honest in marking ISO. For example, ISO12800 set on EPM1 is only ISO7693. That’s why we see the difference in camera settings.

Greg VdB

Le-alain and hippo84 are right of course. Also, different lenses have different optimal settings, and since these are camera reviews I’m sure the apertures selected are those giving the optimal results to not make the outcome depending on the lens instead.

PS: Henry, I hope you do realize that f16-22 gives significantly worse sharpness figures than f8 due to diffraction? Not everything is down to a conspiracy, and dpreview reviewers generally know very well what they are doing…


Do not confuse the DXOmark ISO measurements with indicated camera ISO’s. The latter is what directly affects comparisons seen here, the DXO ISO’s do not necessarily reflect metering or even “cheating”. It’s only a way to normalize output for RAW comparison purposes.

The top of the “noise” page from the final review, will usually tell you how camera ISO’s compare to one given ISO standard ( ISO 12232:2006).

Henry M. Hertz

greg…. that´s exactly why i suggested it.
