A first for me, somewhat and a challenge I stumbled into.
May not have picked the LX7 if I had found the initial tread before the challenge started but glad I did at the end. Ended up with a great variety (somewhat) of shooting settings and the camera is somewhat of a pocket rocket, even though old. The last week I have shot it with a viewfinder (LVF-2) in place and one of those self-opening lens caps and both of those accessories adds to the experience.
It also somewhat, for me at least, brings something more to the table. I had, back in 06-09, thoughts about getting something in the Canon G-series, add the screw in WAC and TC and call it the day, but got derailed by a colleague in 09 back into the (D)SLR world and ended up with a Pentax K7 which I seldom used. Having pondered this a bit, I would most likely have been very happy with the then freshly released GF1 and/or the LX5, and actually brought a camera on many situations, which now is lost in time. Uncertainty and "fear of the unkown" as to Panasonic as a camera producer, as well as bad experience with 110 film kept me off it (M43 sensor size is somewhat equal to 110 negative size).
In relation to this challenge, it has to do with participating with a system that for the 3/4 of the duration, was undertaken with a total investment of $58, which is something I find somewhat intriguing, for me at least. With the add-ons, the price tag is quite a lot higher, but I seriously do like a viewfinder.
