Thank you for your kind comments, all of you:
@Mikebarger: I´d also like to get my mits on a 19mm for just one day. I´ve only ever seen
one on ebay, and it alone could fund the rest of a comprehensive Kowa system, and a probably a user Hassy backup system too
Its as prohibitively expensive as it is rare.
@Sim2: The Caffenol-C-H recipe I´m using has a weak compensation effect, drawing out shadow detail while holding back the highlights. Will result in less overall contrast, but makes for easy scanning and digital post-processing. Micro contrast and grain is very well controlled. I prefer it to the TMAX developer I´ve been using up until now.
@Ahtirill: Haven´t actually weighed it and the lenses. And haven´t a Hassy or the likes to compare with. But its not light. The body with film back weighs slightly more than my D2x (I´d guess 3 pounds or so) and well over 4 pounds I´d estimate with 85mm attached. With the 160, another 10Oz or so. I´ve used it handheld, and ergonomically its quite nice to hold. I do however use it mostly on a tripod, and sometimes a monopod. Size wise I´ve been led to believe its bigger than a Hassy, a bit shorter, but quite a bit taller. This is probably down to the film back which is L shaped and tall, but not at all deep. Build wise it would seem that the most effort into the body, whereas the back is not quite as well finished. Especially the cover is a bit flimsy. What is nice though is the automatic black slide. It folds up at the same time as the mirror locks up. The SIX MM version has a MLU button, whereas the SIX and the Super 66 do not. On these you can use the self timer to perform MLU, as it locks the mirror up prior to counting down for exposure. I can´t say I´ve noticed much shake from the mirror, but then again I use a tripod for the most part.
@Phaedrus: The Caffenol process may give a slight tone in itself, but more likely with stand development, than with agitated. Mine show no tinting as such. Toning is done on the digital TIFF file in post processing (Apple Aperture). I add a very subtle tone, a light golden toning. I prefer this to straight black and white which for web purposes often comes out slightly blueish.
