How can I create consistent sample photos to compare cameras or lenses?

I want to compare different cameras or lenses by shooting my own sample images. What setup and shooting conditions should I use so the results are as consistent and informative as possible?
I’m thinking about using:
- stable, controlled lighting
- manual exposure with fixed ISO
- matching framing/field of view as closely as possible
- a scene with fine detail, color, and contrast
- a tripod
I’d also like to make common lens flaws easier to see, such as distortion and chromatic aberration. What kinds of test scenes or targets work best?

When I do such photos I alway use:
- a tripod to make sure the photo shows the same especially in the corners
- M-Mode with fix ISO-Settings to make sure exposure is same (be careful with fluctuating available light)
Often but not alway I use flash and "kill" the available light to avoid light fluctuations.
To analyses distortions I often use checkered paper or other objects with straight lines.
Scene with good amount of details, colors and contrasts

For useful comparisons, consistency matters most.
Use a tripod so framing stays as close as possible, including the corners of the frame. Shoot in manual mode with a fixed ISO so exposure does not change between shots. Be careful of changing ambient light; if possible, use controlled lighting. Flash can help because it can overwhelm ambient light and reduce fluctuations.
Choose scenes with plenty of fine detail, contrast, and color, since these make differences easier to spot. Matching field of view as closely as possible is also important when comparing different lenses or cameras.
To reveal lens flaws, use subjects designed for that purpose:
- straight lines or checkered/grid paper to show distortion
- detailed test targets or “test constructions” to judge sharpness, contrast, and corner performance
In general, keep everything except the camera or lens the same: camera position, lighting, exposure settings, and subject. The more variables you remove, the more meaningful your sample photos will be.
