Quote: As said I accept PD/CD on sensor AF is more accurate, I see little point in struggling to argue otherwise, but I think we should keep a sense of proportion. However my Pentax K01 proved that even CD AF can get it wrong because it had to be returned for not being able to focus to infinity, so it's not infallible per se.

 

 I was surprised that JoJu was complaining about AF accuracy with his D750 until he mentioned 12,800 ISO F1.4 and 1/40 sec. I'm not sure how dark that is, but it sounds pretty dim light to say the least!............... I'm not sure how the Fuji would cope in the same situation.

........... Could it focus comfortably in that light  thxbb12?

Anyway there are now some Christmas decorations up around the town so I have decided to take some night shots this evening probably with the AF24/35D and my 40€ nifty fifty on a tripod..........

 We will see!........... Normally I will post some shots later tonight........................... unfortunately posting is restricted to piddle-pot sized files here............. on Dpreview's site you can post far bigger files and many more images. 
 

Hi Dave, my comment was for Brightcolours, not you :-)

 

In a very very dark environment, CDAF will also struggle to focus accurately. At such high ISO values, sensor noise is extremely high, so it's very difficult from an image point of view to confidently assess where the maximum gradient is.

Quick answer: probably not.

 

Let us know how it goes with your setup though.

 

I'm done with this thread. Sorry for posting so much here and side tracking the original thread. It's not the first time it happens with BC. As goran h rightfully said "Don´t discuss with BC, he is right even when he is wrong and will always have the last word. ". I think I'll follow his advice :-)

 

Merry Christmas and Happy New Year to everyone at PZ!
