Brian Luce Posted March 8, 2015 Share Posted March 8, 2015 For video I use manual focus on my NX1. Today I was experimenting with auto focus (in vidoe mode). It seem it only focuses fully automatically. Questions:1) is there a semi auto focus mode? Meaning depress shutter button half way, the camera will auto focus, and lock the focus and not hunt regardless if the camera pans or moves.2) If #1 is possible, can you do it while camera is recording? or only standbye?

Jimmy Posted March 8, 2015 Share Posted March 8, 2015 I have not experimented with half shutter yet, but you can use the touch screen to choose your focus point, even when recording. In the menu, you can set how fast or slow or rack focuses too, nice touch. Quote Link to comment Share on other sites More sharing options...
ESGI Media Posted March 8, 2015 Share Posted March 8, 2015 You should be able to set it to SAF and it won't hunt once you've locked a focus point. Active AF that's with SAF but switches to CAF if it notices the focus subject moving. You can also lock it with AF On. Keep your finger on it and it'll lock.

Brian Luce Posted March 8, 2015 Author Share Posted March 8, 2015 OKay, that was easy enough, Looks like it's the AF ON button just above the MENU button that gives you semi auto focus with a lock so it won't keep hunting for focus. Quote Link to comment Share on other sites More sharing options...

I find it super hard though to actually implement such capabilities into my shooting style because I am so locked in to manual focus in video mode. I am essentially terrified of giving up any sovereignty to the software. That's how Skynet got started after all.

Jimmy Posted March 8, 2015 Share Posted March 8, 2015 haha, yea... I'm the same, but it's been fun testing this stuff out. Can certainly see some uses for it.I wonder if the Android app allows for focusing? Will have to add that to my test list. That would be great to have someone operating the cam on a gimbal or something and then using the app to pull focus. Quote Link to comment Share on other sites More sharing options...
Jimmy Posted March 8, 2015 Share Posted March 8, 2015 Just checked.. It kind of works, but seems a bit clunky. Quote Link to comment Share on other sites More sharing options...
Brian Luce Posted March 8, 2015 Author Share Posted March 8, 2015 Just checked.. It kind of works, but seems a bit clunky.I was wondering about a remote shooting app too. I was in an unusual shoot today where I really couldn't man my nx1 , manual focusing was dicey because I only had a few brief seconds to set the shot, and the semi auto focus would've been ideal but i couldn't quite figure it out. A remote app wouldve been perfect as well. sorry to hear it's not too good. Quote Link to comment Share on other sites More sharing options...
Jimmy Posted March 8, 2015 Share Posted March 8, 2015 It's not unusable.... For occasionally setting focus and then recording, it would work fine. Just not that great for rack focusing while filming.Bare in mind I only tried for a few minutes too... Quote Link to comment Share on other sites More sharing options...
M Carter Posted March 8, 2015 Share Posted March 8, 2015 Having single AF can really be a godsend. I use it with Nikons on cranes or even steadicams. Not for the whole clip, but just to set initial focus point.With the D7100 on an 8' Kessler crane, I took a $9 Amazon wired shutter remote, spliced 1/8 stereo male & female jacks, and got a 6' mini headphone extension cable. With that and an HDMI viewfinder, I can get the crane's height and angle set, set the focus point, and trigger the shot.Of course, if focus needs to shift during the move I have to operate from the front, usually with a monitor on a stand or a an assistant holding a VF up to my eye (this can work surprisingly well, especially in bright sun). Samsung has released an SDK for camera control, so we should be seeing some stuff appear eventually in that dept. Quote Link to comment Share on other sites More sharing options...
ESGI Media Posted March 8, 2015 Share Posted March 8, 2015 You know you having Track Focus right? Touch the object on the screen and it will just follow it. Quote Link to comment Share on other sites More sharing options...
M Carter Posted March 9, 2015 Share Posted March 9, 2015 You know you having Track Focus right? Touch the object on the screen and it will just follow it. I'd just looove to see a video test where that actually works for motion. Hey, maybe Samsung will surprise me, but I think you'll start really missing a focus puller with an FF when you try it...

Only published this vid though http://youtu.be/abIuvWgFkgcI haven't had a problem with tracking people, even in busy environments. I'll try and do a test with humans pronto. Just thinking I'd probably want to use my Hyperdeck 2 to capture the screen output for more proof. But yeah, manual focus is still my favourite lol Quote Link to comment Share on other sites More sharing options...
M Carter Posted March 9, 2015 Share Posted March 9, 2015 That would be interesting - you look at the specs for NX1 Af and it really is next-generation. AF that could track without jitters would be pretty amazing. Quote Link to comment Share on other sites More sharing options...

NX1user Posted May 19, 2015 Share Posted May 19, 2015 Samsung just released FW 1.3 with various focus improvements. Update and see what's what. Quote Link to comment Share on other sites More sharing options...
