Df and AF back focus in incandescent light
Apr 11, 2014

Not a why doesn't the Df have the CAM3500 thread!

I have noticed an issue where some of my lenses AF differently in incandescent light compared to daylight. My 1.4G primes are affected, with the 35 being the most problematic.

AF fine tune values between daylight and incandescent light differ by 10 AF fine tune points. This is enough that if the 35 is set for daylight, it is back focused in warm light when shooting at wide apertures.

My other Nikon bodies use the CAM3500 and are not affected by lighting to be significant enough to make an impact.

Is warm light affecting AF an issue which impacts other CAM4800 cameras - i.e. D600/610, or other people's Dfs for that matter,? Or is it just my Df?

I recall reading some time ago about some D7000s having this issue - was it ever fixed?
