Given that I'm very much amateur, if they can reach near enough to the same optical performance I'll forgive a bit of AF inconsistency for a few thousand dollars.
Unless the object is flat, say a coin or a medallion, and the background is empty, say a flat colored background, the photos will not be the same.
It's just like portrait photography, with the nose looking too big relative to the ears when shooting from a short distance - perspective works for the front & back parts of the subject same as it works for the subject itself being in the foreground and other stuff being farther away in the background.
Therefore, if you shoot a diamond ring with the diamond facing the camera and the band away from it, the shorter the focal length the larger the diamond will look compared to the band.
