Nice pictures. I like the two windows best. there is the juxtaposition of a closed secretive window and the one that is open with brightly coloured flowers in the window box and a bird feeder telling us quite a lot about the occupants. In the words of the old cliche every picture tells a story.
For me too the windows shot is a clear winner although it is like comparing apples and pears in this case. Archie said the appropriate wise words. I can only add #1 also exhibits a geometrical quality and a perfect composition.
Both are great shots, but the first one is the stand-out for me. Excellent composition and colour - looks like a great arty pic for the wall. Well done .
The M mount does not automatically record the F number/lens name/focal length, because there way how to do this automatically. Don't forget that there is no electronic connection between the module and lens! So if one wants the F number in EXIF, it must be set manually before taking the photo (or later via an EXIF editing tool). Unfortunately, the actual way Ricoh uses for entering the F number/focal length is very complicated, so most people simply don't care about setting these details.
It is interesting that the Exif on Leica M8 and M9 do show an approximation of the F stop. Maybe something that Ricoh could think about in a firmware update.
Unfortunately the last firmware v 1.50 also introduced a bug where the focal length is no longer recorded in the EXIF, even if it is correctly set up in the My profiles. A discussion is here viewtopic.php?f=63&t=8198. Only solution is to go back to 1.4
