Isn'it it possible that a large rear element force rays perpendicular to the
sensor? This will allow a better image on the sensor and if such an element
is part of the lens design, it won't affect lens performance.
BTW, Sylwek, I cannot access fotopolis.pl. I tried several times every time
you post such links, with no success.
Am I the only one?

I didn't say it didn't work, I don't understand
WHY closer is better because that increases
the incidence angle deviation from perpendicular,
which is bad, severely on the edges/corners
of the sensor.
I can understand why the lens itself is better,
it just seems that the lens/sensor interface
is much worse when the rear element is so severely
close to the sensor. Maybe this sensor is specially
designed for this lens and isnt "flat"?

Isnt is a contradiction that the lens is CLOSER
to the sensor and its an improvement because that
means the light it hitting the corners of the sensor
at a GREATER angle away from perpendicular which
is BAD (perpendicular being ideal)?
Actually samples on www.fotopolis.pl has shown, that R1 performs much
better
than "digital optimised" E-300 ;-)
