I do not think that the 6d with very good optics can drop files so poor.Jpg file you took with the added noise?
mikeoregon: Thanks, Carsten, hope you will keep looking and letting us know what you find. I hike and shoot in the mountains here in Oregon with a day pack carrying camera gear, food, a rain jacket, headlamp, etc. and I still haven't found a lightweight pack that can carry it all, plus a tripod.
I bought this backpack because it is the lightest of all and contains a 600 f4 with a camera body mounted, or a 800 5.6 with no body. Lightness is the size is important in European and international air travel. The dimensions are those required by the airlines, although some company, not just low cost, always finds a way to create difficulties when there are many passengers in flight. The cost is very high, but for me it was the only solution. It has no space for the computer. In my case, after a few days of safari in Tanzania, the zips have had major problems to flow, certainly for the dust that came in the car during transfers. I had to endure this for the rest of the trip, because it is not clean enough. Once back home I washed, but it was not enough. I had to put the wax and now flowing well.
Sorry for the translation with google translator
