Why do you use two different cameras? Just curious. I just bought the nikon P6000 so interested in pros and cons. The bag looks interesting.
Other bags are often too short for a 80mm scope, and the bigger ones are long enough, but heavy and very big in all dimensions (and often also with space for a notebook, which I don't need).
Regarding the two cams: the P6000 is a nice cam, the AF is really good. I was able to improve my digiscoping capabilities with that cam and got some really nice shots. But on the other hand its slow, so I missed some. I use it with a IR remote, because I'm unable to press the shutter without creating vibrations. But with this IR I cannot prefocus. So after pressing the button on the remote, the AF will do its work - needs time and after that the picture is captured. In meantime the bird was away or somewhere else, especially the small and hectic birds like tits. With IR a series of pics is also not possible, so I suggest to go with a mechanical remote shutter.
Before I used a Canon A590 with CHDK installed. Much faster, but not working AF an scope; display more worse. In meantime I thought also about the S90 because of better display and less MegaPixels, but dropped that idea because of slow rate of pictures (speed is comparable to the P6000). The 14MP of the P6000 is a little bit too much.
The G1 is much faster, has a good EVF (good in bright sun) and a better rotatable display with high resolution; a cable remote with prefocus and series is available. With the 20mm pancake I'm satisfied for close distances (with the swaro zoom I have 1000 to 2000mm). For longer ranges I prefer the P6000, until a good lens is discovered.
When I bought my P6000 I checked also the G1, but the price was much higher and there was no usable lens available. The kit zoom was just to long for my adapter and some vignetting was there. The m4/3 pancake was new this autumn.
The body of the G1 is really great with all the best things merged in one light device. I hope in the future there are more good lenses choices.
It is always nice to have a backup for any electronic device, so I will keep my P6000. It can also do video.
