Ricoh GR vs Nikon A
How do you know that there is a difference in focus distance ? It is very strange since the two lenses have almost the same length (18.5 for the Nikon vs 18.3 for Ricoh). The Ricoh has 2 aspheric elements, which is not the case for the Nikon (0 aspherical elements), and since the distance between the sensor and the lens is very small, this is maybe the explanation.
DxO team write "In the extreme corners the Ricoh is brighter, approximately 1 EV at full aperture dropping to +2/3EV from f/4 through to f/16. In today’s digital world, however, vignetting isn’t as much as a problem as it was in the days of film."
Vignetting is not a problem because softwares can correct that ...
I am still curious about the way DxO lens score integrates the homogeneity of resolution across the whole frame.
Anyway, 2 top cameras, both permitting fantastic image capture. Nikon was commercialized before the Ricoh, and the Ricoh is less expensive (250 €) ...
