Pentax K-30 Liveview AF Video

I figure there is probably enough in my other thread. Just a quick example shot using my cellphone. Contrast-Detect AF seems snappy


Set to go with it is Here

Example shot, AF seems good

Wow! Very snappy
And PDAF? Is it really faster than a K-5?

I don't own a K-5 so I cannot draw comparisons, it is however faster than my K20D by a good rate

Here is another video showing the use of the AF button in video mode. It is better to watch it at a larger size (preferably on the YouTube page itself):

That doesn't necessarily mean anything. For all I know, you could be the prime minister of Italy.

I like it. Obviously not something to use in professional video, but it seems to work and do so fairly quickly. Just the thing for making sure the subject of your home video stays in focus. And of course it would be much less obtrusive when using a lens with a silent AF motor.

You can still hear the DC motor on the 18-135mm

I was experimenting with the CDAF tracking mode earlier. At the moment I'm not really sure how much point there is to it. But I'm not sure I understand the use case properly...

I like it too. It beats the heck out of the easily distracted autofocus and the manual (guesswork) focus. I shot tons of home videos between 1989 and 2003. I wish such an AF button had been available to me then (along with autofocus and manual focus).***

***1080p HD would have been great back then too

I'm just wildly guessing here, but Pheo may be referring to his own 18-135mm kit lens, not the lens in the video. Or do you already know this, and I'm simply being way too presumptuous? If so, I apologize in advance.

Nope bang on! Sorry should have been clearer

Do people want a video of the 18-135mm focusing noise?
