New E mount Zeiss 16-70 f4 zoom


I have the error once after that no more so far
 

After 1 week plus having this lens and did some focusing test (which it performed very well, no front and back focus problem, very sharp indeed), I have some trouble while capturing indoor. When i zoom in at 70mm the aperture switch to F-- for 2-3 seconds to adjust to the environment and back to F4 (this happen in indoors and sometimes outdoors). And it's quite fussy in focusing when i'm capturing a sudden interesting moment, it will zoom in and out and it doesn't focus. I need to turn it off and on again, then it will work as per normal. Feel that my little 16-50 still perform a lot better as a walk about lens.

Is this normal?? Should i go back to the shop to have a replacement?

I just update the firmware to Ver 1.02 last night. Still had the same problem. Will try capture more picture to see how's the performance today...

You are using nex 6 or 7 ?
 

Would it be the body and lens contacts issue, try clean it up
Got this problem when I use this lens 1st few days I bought, after clean the contact so far ok

The lens can't expose front or back focusing anyway, your camera works with CDAF. :)

I have the same problem, F-- when zooming in/out, using NEX 5 with 55-210 lens. Sometimes with other lens too, but only like 5% of the time, with 55-210 it happened almost everytime.
After some google-research, looks like the only way to fix is to bring to Sony ... they will replace part of the mount on the camera.
If your camera is still in-warranty, you're lucky.
Mine is out of warranty, so I can only suck thumb :p

I believe the part to replaced is called MB Contact Unit(755).
See part number 264 below (link: http://www.searspartsdirect.com/par...arts/Model-NEX3KS/0996/0500140/50037220/00006).

The original part number was A1773802A, but subsequently has been replaced with A1876371B, maybe because the original component was found to be defective (just a guess).

The price seems to be around US$20-30.
