Blip hunting left late... again.

Uneventful day. D600 sensor cleaned. Discovered it was fairly dirty earlier on in the week, whilst editing photos - spots in the sky of photos taken a fortnight ago today. Wasn't looking forward to tackling it, but was much relieved to find it was just dust, rather than the infamous oily stuff from the well known D600 shutter issues. Some was a tad stubborn, but eventually shifted. Few teeny specs at one side, that are visible at (the never used) f/32. Seems spotless at the sometimes used f/16. As the camera's mostly just had one (well sealed) lens on it, I suspect the dust came from when the camera was refurbished by/for Nikon. Allegedly the shutter was replaced during that work, and that's also likely when the annoying scratch occured to the viewfinder focusing screen. Can't complain, as like the majority of my camera purchases,  it was a bargain, and one of a large batch that the Wex photography shop/website had for sale a while ago.
