A photograph of the London Eye taken with the Panasonic LX3 and then with the Canon 5D Mark 2.
This isn’t a scientific test; the point of views are not the same and the camera settings were different as well. LX3 was also in 16:9 format when I took the shot (the 5D shoots in 3:2 format).
Relevent ExIF for both:
LX3: ISO 80 / 24mm / F5.6 / 1/25 seconds
5D Mark 2: ISO 400 / 24mm / F4.0 / 1/400 seconds
I had no plans to compare the results when I took the shots, therefore the 5D Mark 2 image was under-exposed and corrected in Lightroom; otherwise, I have used the same settings to convert both images from RAW.
Normally, I would correct the lens distortions in Photoshop but for this exercise, I have kept the distortions.
