Tests
- Aperture Sweep
- ISO Sweep (normal contrast scene)
- ISO Sweep (high contrast scene)
- Long Exposure Test
- Over/Under Exposure Test

Cameras
- Phase One IQ3 100mp
- Phase One IQ3 80mp
- Phase One IQ3 60mp
- Phase One IQ3 50mp
- Credo 50mp
- Credo 40mp
- Sony A7 II
- Pentax 645Z
- Canon 5Ds R


[Italics indicate the tests that are not yet done, but should be in the next week]

Big thanks for this effort!

May I ask which type of light that was used for the still life (ie tungsten, flash, daylight etc)

Our own DT LED called the DT Photon (Reproduction LED Light).

CRI of 98, CQS of 98, quite flat spectrum, and very consistent output.

Continuous is much much easier to use on a test like this where you want to be able to bracket a dozen or more stops in some cases.

Hi Doug,

Wow, great, thanks a lot.

I believe you should include a D810 in this test since it has the cleanest low ISO, best DR of all the DSLRs. Another interesting alternative would be an a7rII.

I personally don't see the value of including an a7II.

Cheers,
Bernard

No Credo 60?

Second the A7rII

Hi,

It seems that a nice guy called "pradep" loans out his A7rII for the test.

Best regards
Erik

Yep, saw that. This is good news, but too bad there isn't anyone around with a D810 and an Otus.

I have checked carefully the IQ3 100mp samples in C1 Pro 9.02 at base ISO, and I am not sure to see better pixels compared to those I am used to. ;)

Cheers,
Bernard

Hi Doug,

What lenses are you going to shoot the Pentax with?
Hoping you'll put that new 90 Macro on.

This is going to be really interesting.

Cheers

I don't see where it says a A7R2 will be in the test.
What are the lenses to be used/paired?

Hi,

It doesn't say. We need to wait and see. Doug asked for the Sonnar 55/1.8.

Best regards
Erik

They're not going to test the 90mm macro, they're testing the 28-45mm and the 55mm.

They originally were not going to test the A7R2, only the A72, however I believe someone agreed to loan them an A7R2 for the test and they agreed.

I don't see where it says a A7R2 will be in the test.

Because not everyone has your technical proclivity to useful analyze the distribution of slope in a spectral chart of a lighting source :).

If you have a serious interest in the lighting please feel free to email me and I'll provide you all the spectral analysis one could ever hope for!

They're not going to test the 90mm macro, they're testing the 28-45mm and the 55mm.

55mm kit lens and 90 macro was included on this test.

The 28-45mm was rented for a different test I hope to be able to post next week comparing SLR wide angles on a more distance subject. Only one wide angle was used in this test and it was the 25mm Batis for the Sony included because the gentleman who was nice enough to loan us his A7R II asked the 25mm to be included.

Sony A7RII
IQ3 100 certainly has better CFA/IR cut than A7R2 = http://s26.postimg.org/jnfvtomlj/IQ3100vs_A7_R2.jpg

look @ blues for example no mudding reds inside
