That's just how it is- what you're describing is normal. You have to press the AF button, and this only yields a slow type of AF while recording.

Things improved slightly on the K-70 thanks to on sensor PDAF, which allows for continuous video AF.

Pentax.


Pentax have devoted little effort to the video function, so even customers buying new products are still being given essentially the same video functionality as 2012 models.

If you prioritize video, including auto focus during videos, then Canon is your brand. If you want the best stills camera for a given amount of money, Pentax rules.

If you bought a small Honda Civic and was annoyed it couldn't fit a full sheet of plywood inside, it's the same sort of issue. If you need to haul things, get a truck. If you need to get just you around the city, the Honda is better. They're both vehicles, both can carry things, both can carry people, but different design priorities.

No I think that's too extreme.

This is more like if you thought your car would have aircon (which all other cars now do) and when you took it in to be looked at, were told by Pentax that they still only offer manual wind down windows.
You'd find that pretty weird.

Nowhere on the box does it say Pentax doesn't do video very well, and this thread is a classic example of this. Someone gets a Pentax and thinks it's broken because it can't autofocus in video mode, which nearly every other camera can do as standard nowadays.

Autofocus whilst recording video has ruined quite a lot of shots for me working with a dedicated Sony video camera. Be careful what you wish for...

I would certainly agree with your comment about Pentax still quality vs that of Canon. As for video, most people that shoot fairly serious video nowadays would recommend SONY or Panasonic over Canon for video. Canon is way behind the curve in terms of the IQ of both 1080 and 4K at somewhat affordable price points.

As FRIES noted, autofocus video can get you in trouble at inopportune times, regardless of brand.

Agree.

Itís worth mentioning you could always turn this function off, if you didnít want it. You wouldnít be forced to use it, but you should at least have the option in 2018.

I suppose so, but the Pentax has so many features the Canon and Nikon DSLRs don't have at a reasonable price point; their budget models don't have real pentaprisms, WR, in body SR, focus confirmation with MF lenses, compatibility with old screwdrive lenses, moire reduction, a solid build, TAv mode, and on and on.

I'd also say nowhere on the Rebel 6Ti box does it say that the camera has a seriously poor excuse for a viewfinder and the dumbest menu system ever conceived.

Iím not denying those real Pentax strengths, but Iím also not blind to the embarrassingly bad weaknesses either. Pentax hasnít touched its video offering in 6 years now, and itís hurting the brand.

Some quite entry level Canons have their vastly superior dual pixel AF system and decent video capabilities, including AF during video capture.

No sorry. The K-70 model Pentax camera does have AF during video mode, but all the others donít have it. Buying a lens unfortunately wonít change this, the body simply canít do it with any lens.

As you say, planning your shots around this will help. There is AF before you start shooting, so aim to keep your subject the same distance away from the camera when you are recording.

There is also Manual Focus, but the focussing aids of digital zoom and focus peaking also stop when recording starts.

Good luck

No worries at all. There is lots to get your head around, and this forum is a great place to learn more about your Pentax equipment.

Basically most Pentax cameras cannot autofocus whilst recording video, so you have to prepare for this by focussing before you start recording. If you keep your subject at the same distance from the camera, it should stay in focus.

Or select an aperture like f11 that will keep more of the scene in focus, so the specific focus point is less critical.

Good luck

Pentax K-S 2 has almost the same price as Canon 800D, but the 800D has some advantages that is hard to overlook when you try and sell it to beginers and one of the most important one is their marketing. Canon with their entry level cameras is targeting:

1. parents of small children. Canon is advertising their entry level cameras as very good in capturing action. And if you look at the Af from the 800D, on paper is looking more advanced than the one from K1. It shoots 6fps and uses 45 cross-type AF points (45 f/5.6 cross-type AF points, 27 f/8 points (9 cross-type), centre point is f/2.8 and f/5.6 dual cross-type).

2. beginers vloggers. Again, 800D has tilting LCD with touchscreen and the impressive dual pixel af

Pentax K-S2 may be a better camera overall than 800D due to the features that you mentioned, but these days people (young generation especially) are no longer interested in focus confirmation with manual lenses, compatibility with old screwdrive lenses or TAv mode. At least not when comes to entry level cameras.

As I said on more occasions, to me Pentax is looking like a company that is targeting more and more the landscape photographers with their current cameras, which it may not be a bad idea considering the fact that they are not going to invest the necesary money to compete with Canon, Nikon, Sony on other levels. But, if Pentax will have difficulties in the future when comes to market share, one main reason is their lack of marketing and sales strategy.

Just a observation... This topic is in the troubleshooting and beginner help part of the forum. Athough I respect anyones wish to express their opinion about Pentax as a camerabrand I suggest there are more suitable parts of the forum for that and concentrate on helping fellow members in this part of Pentaxforums.
