I'd like a newer model for free/cheap, of course, but the original for me is far better!
Metal casing: my first Q has survived knocks and falls that I doubt any newer plastic (ooops, sorry, polycarbonate) model could withstand.
Also, scratches and dents looks so much better on a black metal body. My only complaint in that department would be that the metal underneath the black paint is white and not brass gold like the original Spotmatics and such. That's progress, I guess. So I've bought two more black Q bodies with the 01 lens as backups.
Portability: I almost never use the 01 lens, but instead various strange adapted concoctions. My favourites are body-cap conversions of cheap and cheerful CS-lenses. Normally I use 2,8mm, 8mm and 12mm (all with fixed f:1,2 aperture). With the 2,1mm/2,5mm/2,8mm adapted CS-lenses the Q goes down the back pocket of tight jeans with no problems at all, except when I want to sit down...
.
IQ: As you may have guessed, the IQ is of lower importance when I use these lenses. But I think the two examples from the 12mm and 2,1mm below shows that you can get almost acceptable results even from lenses in this 3-4 US$ price range.
f:1,2/12mm CS / JPG straight out of Q / downscaled to 1024x: f:1,2/2,1mm CS / PP in Q / downscaled to 1024x:
And if anybody is interested, I could sell off one (maybe two) unused, mint, 01 lenses!
Location of lenses: South Sweden.
