Night vision

This is a bit of a rushed post, as I am still recovering from a cold that I caught during my trip to Kos.
Having taken over 200 images on my Df, I have learned quite a lot about this camera.
One thing that I am comfortable to let it do is to use high ISOs that would previously been unusable on the D700.

For all shots, in-camera noise reduction was turned OFF.
I'm no expert in removal of noise in post-processing but this was handled for me by Topaz DeNoise 5.

The first shot was totally usable in colour but since the lighting was a very uninteresting sodium streetlamp, I decided it was better in B&W. Even at pixel-peeping levels the noise is very "organic" or film-like and pleasant.

The second photo of the cat was taken by the bottom steps of our hotel.
I'm not sure if I achieved critical focus but you might imagine how dark it was by looking at the size of the pupils of the cat's eyes. If that was a lens, it would be at f/1.0 :-)

Again, better in B&W as the red carpet was a bit distracting but fairly usable in colour?

Being Greece, cats are abound and seem to proliferate at night. Most of them scuttle around the bins or between cars but some prefer to do as humans do, hoping that they are out of sight.
Here again it was extremely dark and both the camera and I had trouble focusing.
I think the cat detected me but was a bit spooked by not knowing what I was up to!
Again I think the noise is OK, especially for web upload.

Backlit sycamore

This sycamore tree was indirectly backlit by powerful spotlights...still too dark so had to employ a high ISO and didn't want to use flash.
I wonder how a more recent sensor (Nikon DF or Sony A7R) would have handled it?

The 24-70mm I used here is now gone but I also wonder how my 85mm f/1.4 would have fared here. Like many photography enthusiasts, I started with fast zooms but I prefer even faster primes ;-)
