As for changing lenses... not sure exactly what you mean? I.e., because it's cold?
Ron, yes, I mean change lens in cold, even not in cold, I feel awkward changing lens How you guys clean your sensor? That is why I like the idea of have either a 50 or 35mm fixed on M for most of view with another small body with a zoom to secure the shots as needed. Thanks for post the environment shots of that art piece, there is no way I can fugue it out. it looks smaller than I thought. I agree your earlier set are more impressive.
Ron, thanks for sharing with us on the art installation and your shooting process.
I was about to ask the same question about switching lenses so often, not only in the cold. Also aren't you worried about having dust on the sensor since you seem to change lenses so often? Lenses uncapped both ends?
On another note, I received my 28Cron back from DAG last week. Took Don just over a week to collimate it back to spec and code my 90 Tele-E.
Joe, curious why you sent it to Don rather than Leica? I guess he's less expensive? And you did get very fast turnaround too.
Changing lenses: I guess not researching a lot on LUF or RFF and not working for years with film RFs, I didn't have an informed RF background when I jumped into the M9 system as a partial proxy for DSLRs, which morphed into a hybrid workflow that retained some of my SLR habits, including frequent lens changes. To me this is completely normal behaviour.
My right middle finger practically rests on the lens release button when holding the M9. It's become quite instinctual and easy to jab that button and twist the lens off, deposit the lens in its compartment in the satchel and pull out another one... No, I don't typically cap lenses while working as it really slows things down. This is also my habit with SLR lenses. Perhaps it's an aspect of my work background where sometimes speed is essential. When the weather is bad and if I have time and am dealing with more gear than usual, such as the recent 21mm lens review, then I will cap at least the rear. The way the internal pockets are designed in the CourierWare satchel I use (it's the mini, the smallest one they make), they're sewn to the inside side of the bag, but when something bulky such as a lens is in a pocket, the bottom of the pocket ends about an inch above the bottom of the bag. The lens is kind of suspended from the side of the bag and not resting on the bag bottom. I place the lens either front down because the hood will provide sufficient protection for the front element, or sideways. I try to avoid placing them bottom down, as pretty much all the wide angle lenses have rear elements that extend beyond the lens mount. The only catch to this system is the pockets are not padded, therefore I try to avoid running to prevent items bumping around inside the bag. But because the CourierWare guys allow a fair amount of customization when you place an order, I believe they might now be able to offer some thin pocket padding for an additional charge. BTW, CourierWare is the company that makes the Bare Bones Bag. I found this review quite helpful. Though it's for a much larger bag, much of the concept translates to the smaller bags and M series equipment.
As for dust... yes, it's a problem. The day after the snow photos I posted here, we went back again and I shot a bunch at f/16 (for the depth of field) and was quite surprised to see just how much dust was on the sensor! But even with 21mm lenses, if shooting at f/8 and wider, the dust often is not that noticeable. If it's an infinity landscape, then even f/5.6 is enough and dust will be even less noticeable. Or, just get a few Lux and Cron lenses and only shoot wide open.
So far for cleaning I've only tried dry methods, but have noticed whenever the camera went back to Leica (either NJ or Germany), that they'd do a wet cleaning (because there would always be a touch of swabbing residue). For dry cleaning I use a blower bulb along with a sensor pen. I recently also picked up one of those silicon stampers, but haven't yet tried it: http://www.amazon.com/gp/product/B0019K8YVM
