This was taken with the D600 and 105mm AF-S 1:2.8G ED VR from the same position, about 12m away

I am somewhat confused by this lens. Focused at infinity, it is very difficult to get a truly sharp image. I must however concentrate more on positioning the single focus point and keeping it on target while I squeeze the trigger. Nevertheless, there seemed to be colour fringes around the flowers under the bird feeder taken with the D600 - chromatic aberration?
On the other hand I am almost pleased with the dragonfly shot.
The pigeons taken by the Powershot are in colour, while the D600's have been edited to monochrome. Our resident lovebirds are at it every evening
I find it difficult to believe that the camera might be faulty - it has a repair to the beak over the lens where it has connected with something hard. The flash unit has probably been replaced, and the viewfinder lens is not fully central in the moulding -only fractionally.
There is dust in the lens next to the mount - is this indicative of wear? all those moving parts :(

I am a little confused myself.
According to the exif for each of those images, there are significant setting variations between the images.
For ALL the D600 images the exposure compensation is -0.7……why?
The Canon shots have exposure compensations of 0 for the feeder image and -1.1 for the pigeon image….again why?
The full numbers comparison……
The D600 feeder image settings are :
1/320th @ f16 and iso 2000 exp comp -0.7
The Canon feeder image settings are :
1/25th @ f8 and iso 100 exp comp 0
The D600 pigeon image settings are :
1/1000th @ f8 and iso 640 exp comp -0.7
The Canon pigeon image settings are :
1/500th @ f5.9 and iso 100 exp comp -1.1
I don’t understand why these settings vary so much, if you want a fair comparison? I haven’t worked out a basic “stops variation” but the number of stops differences between these images looking at these figures would seem to me to be significant.
Leaving aside the lens performance, if the camera sensors are working with widely different settings, that alone could account for drop off in IQ. It could certainly muddy the water.
