I haven’t noticed this issue on my D600, which is a great camera, and I prefer it to the D800 I’m going to sell.
The D800 has a left focus issue, which Nikon seems to be in denial about, where if the center focus sensors focus properly, when using the viewfinder, the left focus sensors when used will be out of focus.
The D800 is a great camera, and it doesn’t affect the landscape type photography I mainly do, but there are a great many photogs not happy with their $3000 paperweights.
I prefer the D600 for its smaller size and lighter weight, and the fact that it uses the ML-L3 wireless remote, about the size of a matchbook and selling for less than $15. Extremely convenient compared to the clunky and expensive rig you need to do the same thing with Nikon’s pricier cameras.
Anyway, Swampie, thanks for the heads up. I’ll keep an eye out for dust in my pics.
Later.
I've got an illuminated sensor loupe, I can really do a thorough inspection of the sensor. It was a good investment.
