In Topic: Zeiss Touit 2.8/50M for Sony E-Mount

Thanks again Bill.  I was getting close to upgrading to the a6000, but I think I'll wait for its replacement - maybe Sony will respond to the Oly challenge and give it better features.  Did you mean Zeiss 50?  If so, I totally agree re speed - it's the hunting that gets me, but apparently with the a6000 there is an option to switch off the pre-AF, which might fix it.

Thanks Bill. 

 

That's interesting about the close proximity of the buttons making them difficult to use.  Given the compact size of the Sony ILCEs, it's always going to be a challenge for the housing designers to keep the buttons apart - best example is the cruciform group to operate the main control wheel - they must be pretty awkward in drysuit gloves too.  On the NEX6 housing, the AEL button is also next to the video control, and using the 3-click trick to switch from AF to MF and back on the NEX6, I've never hit the video by mistake: from the pictures of the a6000 housing, the position looks very similar, so I wouldn't anticipate an issue. 

 

But then, I'm a confirmed warm-water diver ... and you're an Olympus user. :laugh: :pardon:

Here is the explanation from Zeiss:

 

Out of factory, the Sony NEX cameras come with its AF enabled all the time, as long as the camera is switched on and before it switches down to power save mode. So the AF of NEX cameras is always active, independent of the lens that is mounted (AF E-mount lenses only). Because the AF motors in some other E-mount lenses (e.g. Sonnar T* E 1,8/24 ZA) are more quiet, this is a little bit less noticeable, whereas the more robust and therefore louder AF motor of Touit lenses underlines this standard behaviour of NEX cameras.
Touit lenses exactly behave identically with all other typical AF lenses with E-mount in this point.
In practical use and to save battery power, we recommend to disable the AF in the menu of the NEX-7 and to press the separate AF/MF button on the camera´s rear side to focus directly before shooting.
Unfortunately, other Sony NEX models are not equipped with a separate AF/MF button to active AF while the camera is set to MF. With those cameras, we recommend to set the “power saving start time” to a small value.
 

The NEX6 can't be set to back focus.  However, it seems that the a6000 can: http://www.dpreview.com/forums/post/53675229

Thanks Alex.  Good to know it's not just my lens, then.

Thanks for your help, buddy.  Sadly back focus is not a feature at all on the NEX6, which is why I have to do the 3-click faff to switch to manual and back.  I wish Sony had thought that one through better!   You're right that the lens' behaviour is odd ... maybe I ought to check with the retailer whether it's actually a fault.

 

Thanks for the compliments on the pics.  The hammerheads were an amazing dive - they were down at 45m+ so I had to stay above them given I was on EANx, but they just hung around for ages with no shyness at all, maybe around 20 of them big and small.  W/A is the 10-18 which is a fab lens, even though it's rectilinear.  Full list of kit is on my Flickr profile.
