^ go shoot something interesting please

yes sir

i have to agree with razu

+1

But you said already calibrated 'correctly'? Or the range +20 to -20 is not sufficient for your calibration?

not sufficient, and this is sometimes a prob when the subject is far.

I guess that's not an issue with the center AF, but most likely the AF module is totally offset...

its really frustrating, first because i paid alot for this. 2nd is sometimes its in focus, sometimes its not. mostly far subjects dont really need the AF fine tune, but for subjects closer than 1 meter, it needs more than -20

and to make it worse, i thot it was the lens. so i mounted it on my D3 and everything is is super sharp focus

have u send urs in buddy?

Not yet, I don't stay in KL so gotta wait till the weekend before I can send it in need to travel all the way to KL for this. I know when focusing far away even my D700 has issues at times, but close up my D800 is still alright only the left hand AF consistently back focus as per the results I have shared, totally no issues with center or right.

I'm thinking your unit has major offset in terms of AF... you probably need something like "-30" perhaps? which is why your left AF is 'in focus' while both the rest is out of focus?

i dont really use my left or outer focusing points. but when this issue raises i did tried mine. yes probably -30.

btw have u tried Live View Autofocusing? with LV AF, its gonna be super sharp.

that's how i know my middle point is not good enuf. with no AF fine tune, with -20 AF fine tune, both seems to hav misfocus probs, its better with the -20, but with LV AF, its damn sharp. we're talking middle points btw

Yeap, LV focusing is my reference.



See my left focus is consistently out with 3 tries, but ok with LV. The rest LV and AF shows pretty similar results.

That terrible bad on left AF

seems like mine doesn't affected with the AF issue..
tested on 24-70@ 24mm F2.8, and 85mm @ 1.4
both oso doesn't show any different compared to live view.
i tested Left VF-AF VS Left LV-AF, center VF-AF VS center LV-AF, and Right VF-AF VS Right LV-AF.
i use timer + exposure delay 2 seconds, camera mounted on 190cxpro3. the picture is exactly 1 meter away from the front element of the lens, when 24mm picture is taken.

selected picture is LV AF, while candidate picture is VF AF for left most AF point


hopefully all newer batch has the problem settled..

Its only slight OOF, but due to the lens is 35mm f/1.4 it kinda amplified the severity. Oh well, hopefully Nikon Msia able to fix in a go and getting back before 22nd December.

currently still no chance to take picture during day time.....mostly take at night one

Closer focusing distance will be more obvious due to the more shallow DOF, you will be able to detect even slight error; but the slight error might not be noticeable by everyone, or perhaps it's more obvious when you're the user; Hence when going to the service centre, sometimes they might not be able to see the problem of very slight error.

But your case is really obvious, hope they can fix it properly and not leaving any slight error.

street price or the retail price from nikon?
can start to save money for this..hahaha
