Big camera, little camera...

To take these pictures, the cameras were put in Program mode with ISO set to Auto, just to see how each one would meter the scene. All of them were wearing lenses that are the closest approximation I have to a 50mm f/1.8 full-frame lens, for that respective sensor size.

This picture was taken using a Pentax Q-S1 and the 01 8.5mm f/1.9 lens. Lens corrections were applied in Photoshop, but no lighting correction. With the 12mp 1/1.7" sensor, the less attention drawn to the noise in the shadows, the better. (The camera selected 1/60th @ f/1.9, ISO 1000 for the shot.)

This was the Nikon 1 J1 and the 1 Nikkor 18.5mm f/1.7 lens. The Nikon, with its slightly-larger-than-the-Pentax 10mp 1" sensor had the hardest time with the image. The camera went for 1/60th @ f/1.8, ISO 900. Trying to save the highlights using the auto function in photoshop left the shadows noisy. I could go in and tweak, I suppose.

Lastly, a Fujifilm X-E1 and Zeiss Touit 32mm f/1.8, which the camera shot at 1/55th @ f/1.8, ISO 800. The 16mp APS-C has plenty of dynamic range for the picture, but now we run into depth-of-field issues. The longer 32mm lens (still roughly a 50mm FF equivalent) has such a shallow DoF at this range with an f/1.8 aperture that the book spines are nicely in focus, but the cameras in front of them are starting to blur, and the boot toes and lens fronts are noticeably blurry.

Now my OCD self wants to repeat the scene with the EF 50mm f/1.8 on the 5D Mark II, but I'll have to wait for tonight.
