Thanks, FL. However I mean the kind of hand grips which give extra wrist security, not a battery grip.

I had a feeling I was getting the contrast/phase detect AF systems mixed up! Oops, thanks for the heads up.

I have recorded some (VERY) low light video. This is single street light stuff, and tres difficult. Also I'm not familiar with DSLR Video yet. Still, here is is:

High ISO Stuff, taken on a Gorilla pod attached to our balcony(!)



















I'm not noticing any problems with autofocus here - neither CDAF nor PDAF - Unless I point it somewhere so dark I struggle to manually focus (i.e. we have to be realistic)

Also WRT tungsten, the only tungsten bulbs I have are Halogen - and I'm not having issues here at all. I'll keep monitoring this and looking for scenarios.

The embedded flickr pix aren't being served up to me, for some reason. They are there on your flickr, but I just see the flickr 'This image or video is currently unavailable' image here.

Thanks for posting those Pheo! Those low light photos look pretty good to me. Definitely enough for my uses, and thanks for your real-world feedback, people like me are hanging on every word

No problem, I pick things up quickly but I'm not normally one of the first!

I'm not sure why Flickr is not happy - Its doing it to me also! Standard settings were used.

Is it possible that ithey cannot appear here on PF because you don't allow downloading of your images on Flickr? If they are embedded here on PF they will be downloadable here. I suspect that Flickr prevents it for that reason.

Seems to be working for me sporadically.

Anyway:

The resolution is pretty awesome - both the cam and the Sigma 8-16mm!

Pheo, could you please try continuous autofocusing test similar to what CameraLabs did with D7000 here:
Nikon D7000 review part 2: Continuous Shooting and AF on Vimeo (time 10:20 of the video)

and LV continuous AF as seen here:
Nikon D7000 review part 3: Sensor and image processing on Vimeo (time 6:40 of the video)

I didn't even know it could do that...

I shall try this evening - I'm presuming this is what AF.A mode is for!

IF anyone knows more about how this works on Pentax Cameras (when I bought my last one, nothing like this existed!), or the appropriate point of the K30 manual that'd be useful so I can avoid human error.

I'll have to see if my iphone 4s can record into the viewfinder!

Thanks for that summary. Just FYI, the 18-135 has a DC motor and is not an SDM. The difference is that the 18-135s do not have a reputation for just plain breaking for no apparent reason, the SDM lenses on the other hand.......

OK, so I cannot get scenario 1 to work (PDAF Continuous) - However My K10D didn't have this so this might be user error. Obviously AF-C continues to work in the regular way, but I've not figured out the tracking yet.

On LV CDAF this seems to work OK, again I've got no basis of reference, and I'm not sure what the usual limitations are with this type of thing on any camera system.
