This is for all the pixelpeepers out there. You can now compare the Canon EOS R3 image quality in a studio scene setting.

DPReview added the Canon EOS R3 to their studio scene tool. You can now analyze the image quality of Canon’s first stacked CMOS sensor and compare it to other imaging sensors.

Our test scene is designed to simulate a variety of textures, colors and detail types you’ll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.

Click here to access the studio setting tool, and have fun.

You can download the Canon EOS R3 user manual from Canon. Or you might read it online. A technical brochure about the EOS R3 is available. You can watch the EOS R3 live-stream again here. All EOS R3 coverage is listed here. We put together some interesting videos about the EOS R3, listed here. Be sure to check Gordon Laing’s in-depth review of the EOS R3, part 1 and part 2.
