Anyone using this combination & managed to get the lens to actually focus on the point you want it to? I've just run another series of fine focus tests on both my D800s & Nikkor primes - all of which are within a +/-3 to 4 range to fine tune them. Except, the 135DC - & I've been through 3 of them now, all brand new. Each & everyone of them is at +20 on both bodies and still front focussing beyond an acceptable level. Nikon UK are aware but I'm not holding my breath for a sensible response or indeed any admission the lens won't work on a modern camera. I was told by the retailer the lens isn't satisfactory on a chip over 24Mp. A lens either focusses or it doesn't, regardless of chip size. Testing set up:- LensAlignPro -tripod mounted. Camera tripod mounted, base ISO @ 320th. Fired via cable release & mirror up to eliminate any potential vibration problems. Light by strobes.
