Follow Focus and drift-- advice? https://personal-view.com/talks/discussion/6626/follow-focus-and-drift-advice Sun, 07 Apr 2013 11:35:44 +0000 Brian_Siano 6626@/talks/discussions Last night I shot a theater performance with my GH2. But the event was lit for theater, not video, so it was very dim. So I borrowed a fast Lumix 20mm prime lens. This also meant a shallow DOF, so this was a chance to try using the Fotga follow-focus rig.

I ran into a problem. I marked the furthest and nearest focus points on the Fotga's white wheel. That way, I could focus based on the distance on the wheel marks. However, I tried racking the focus back and forth a bit, to get a feel for the thing... and the settings drifted. I'd rack the focus to the mark for the back of the stage... and it wasn't in focus. Same thing for the nearest point. I'd recalibrate, but the points would drift again.

Now, there's a bit of play with the Fotga follow-focus-- and I was using a small 12mm lever that added a little more play-- but I'm wondering if there's some issue with the lens or camera settings that may have contributed.

(One thing I did learn: as you rack focus during shooting, the GH2 displays a line on the screen, i.e., mountains versus flowers. I wound up making an estimate of focus based on the indicator on that point. Seems to me that I could apply cellophane tape to the screen, mark the points on that, and use the screen's focus indicator as my follow-focus marker.)

Can the GH3 replace a Traditional Video camera for Amateur work? https://personal-view.com/talks/discussion/6331/can-the-gh3-replace-a-traditional-video-camera-for-amateur-work Tue, 05 Mar 2013 11:16:18 +0000 mpgxsvcd 6331@/talks/discussions I have been shooting indoor climbing competitions for years with Micro Four Thirds cameras(GF1, GH2, and now the GH3). I don’t shoot professionally. I simply record the event and share the videos with anyone who wants to see them.

I thought the videos were good in the past. However, the lack of image stabilization, accurate Continuous Auto Focus, and a good wide aperture zoom lens were always mentioned as limitations with my videos.

Finally with the GH3 I think we are over that hurdle. The video below was shot entirely hand held(No tripod or monopod at all) by 1 person in continuous Auto Focus mode with the 35-100mm F2.8 lens. I also only used one battery and still had some juice left after more than 4 hours of filming.

I would say that the focus was spot on for pretty much every clip. Even the focus pull at the beginning from the guy’s Ipad to his son climbing worked perfectly. That was a one take shot. If I didn’t get it right I couldn’t ask the guy and the climber to go back and do it again.

I simply slid my finger from the Ipad to the climber on the camera’s LCD screen. I think it gave the video a very nice effect.

I had other lenses with me like the 25mm F1.4 and the 14mm F2.5. However, I never felt like I needed them. At F2.8 I was almost never above ISO 3200 even with the darker lighting they used for this round.

I think the IS was terrific in the 35-100mm lens as well. Yes I would rather have had the OMD’s 5 axis stabilization. However, I think this is the next best thing. Try holding a camera up for 4 hours straight with a 200mm 35mm equivalent focal length and see how shaky it is without good IS. I also like to take images while I record video and instantly upload them to the web so that spectators can follow along with the action with real-time pictures. With the GH3 I put it in the real time wireless upload mode and shot at 1080p @ 60 FPS in the stills mode. That way I could take stills during video and instantly upload them.

The only issue I had with that is that every time you press the shutter button to take a still it will initiate a focus adjustment. That actually made the focus go off more times than not. After noticing this I just decided to save images directly from the videos in playback mode(Press pause during video playback and then save an image). The camera will upload those images in real time as well.

I have tested the quality of images recorded during video recording and images saved during playback and they are indistinguishable in my opinion.

I also mount my GoPro 3 Black on top of the GH3 and shoot simultaneous wide angle 720p @ 120 FPS video. However, I scrapped all of the GoPro footage because it simply was not up to the caliber of the GH3 video. It is great for super slow motion but the 120 FPS mode indoors produces so much noise that it would not mesh well with the excellent video from the GH3.

I also was impressed with how well the youtube encoding turned out. I normally post to Vimeo as well because it is better for compression. However, in this case I thought the 1080p youtube encode looked great.

I didn’t alter the video at all. I did not do any color grading or post processing on it. I shot in scenery mode with -2 Contrast, +2 sharpness, Zero Color, and -5 Noise Reduction and simply pieced the videos together with a cheap($50) program called AVS Video Editor.

It was really nice to be able to produce the video with the footage as it was shot in camera and still get what I thought was a decent result.

There were plenty of other professional film crews there with much more sophisticated equipment. The little 11 year old girl in the last clip is probably the 2nd best female climber in the country(At 12 years old) and she has a film crew that follows her around everywhere she goes. I wonder how much better their footage looks?

So what do you think? Is the GH3 finally the camera that would make you put down the traditional video camera if you shoot both stills and video?

GH2, 20mm Pancake and follow focus? https://personal-view.com/talks/discussion/5664/gh2-20mm-pancake-and-follow-focus Fri, 04 Jan 2013 14:42:56 +0000 rod 5664@/talks/discussions Hello, I use a GH2 and a Edelkrone Pocket Rig. My problem: I need a follow focus I can use with my Pana 20mm, 1,7. Problem: The focus ring of the pancake optic is very close to the camera body. With "normal" solutions the lens gear is blocked by the camara body. Any ideas?

The follow focus should also work with the Pana 7-14 and 14-42, Nikkor: 24 2,8; 35 2.0; 85 2.0; 180 2,8. I guess, with all these lenses there will be no problem - hopefully.

Continous Auto Focus based on contrast - why don't they just... https://personal-view.com/talks/discussion/4974/continous-auto-focus-based-on-contrast-why-dont-they-just... Tue, 23 Oct 2012 18:39:25 +0000 karl 4974@/talks/discussions I guess we all agree that in controlled environments, manual focus will always be favourable for shooting videos.

But whenever the environment is not under control, a well-working continous auto focus can be really, really helpful.

Yet all the recent implementations of continous auto focus in cameras using contrast based focusing suck - they just don't work good enough to be useful. They are either to slow or do too much visible "focus hunting".

I understand that any focusing based on contrast only will require some sort of "hunting", because the direction in which to adjust the focus plane cannot be predicted based on contrast only.

But continous focusing is relevant mostly for video (not for still images), and the resolution of the sensors is usually much much higher than the resolution of the recorded video. So it seems like a very obvious idea to adjust the focus plane only by the smallest possible amount (according to the step motor of the lens), one step back, two steps forward, one step back, and if properly sized, these steps are small enough that the change of the focus plane is not perceivable in the (relatively low) resolution of the recorded video, while it is still big enough to yield a significantly different average contrast in the (relatively high) resolution of the sensor.

I am pretty convinced that my old Sanyo hybrid camera did precisely that: With just one sensor chip and no phase detection, it could only base focusing on contrast. While shooting video, you could hear a very faint noise that was indicating the lens was focusing back and forth just a little - not as much as to be visible in its 720p output file.

Now I wonder: Why don't they just implement this simple method in current cameras? Why do they follow this primitive approach of "accepting some variation in contrast without moving the focus plane at all, then suddenly hunt focus from scratch"?

Anamorphics For Sale - Sunday Only - Cheap! https://personal-view.com/talks/discussion/3963/anamorphics-for-sale-sunday-only-cheap Wed, 18 Jul 2012 19:11:13 +0000 BobbyMcDonald 3963@/talks/discussions I could really use some quick cash for an upcoming trip, so these two adapters are heavily discounted, only $199 each.

1) Sankor Compact Anamorphic - A 2x lens, focus scale marked 5' to Infinity with about 270 degree rotation. Glass is pristine, body is in great shape minus a scratch in the paint, mechanics seem in good order, though there is a small bump when you first start rotating the focus ring, like a hiccup... pretty small, but still there, could just be a loose screw or something. Will likely need a clamp to mount, unless you feel like drilling holes through the overhang of the lens barrel. Asking $199 + shipping.

2) Delft (Delrama) Vistascope - A 1.5X focus through comprised of a pair of mirrored prisms. They were tarnished, so I just had them sent off and re-silvered, should now be a factory fresh image. This is the rarer and easier to work with 16mm version (Marked "16mm f=600cm"). Body is in decent shape for a lens of it's age, there's definitely some paint wear and scratches. Glass is clean and clear. Comes with a series VI to 49mm step up ring as well as a 49-52mm step up ring. Only one caveat, at the moment I can't find the four screws to reassemble the body. Shouldn't be hard taking it to any hardware or camera repair shop to find the match, but I probably won't get to it for awhile, so I'm dropping the price $50 to compensate. Asking $199 + shipping.

The price here in Europe (including customs and taxes) is about 2000€ for this set. You can google it and convince yourself.

The reason for the sell is a malfunction of the front handles. They are not very stable, meaning you can´t tighten the screws as much as necessary. But this shouldn´t be a big problem, as you can replace them with other handles from the same or a different manufacturer. The rest of the Rig works fine and is absolutely sturdy!

Price: 640€

Arthurian Brocéliande - Tokina 11-16 Driftwood VY Canis Majoris https://personal-view.com/talks/discussion/4345/arthurian-broceliande-tokina-11-16-driftwood-vy-canis-majoris Thu, 23 Aug 2012 15:32:45 +0000 richardwouter 4345@/talks/discussions Some footage that I shot on holiday in France with my Panasonic GH2 and Tokina AT-X Pro 11-16 lens. Shot in the Paimpont forest (said to be the Arthurian Brocéliande) and near Mont Saint-Michel. A timelapse at the golden hour before darkness.

Just for fun to play with my new wide lens. No special grading.

Camera : Panasonic GH2 AVC-Intra (Driftwood VY Canis Majoris Day PM) Lens : Tokina AT-X 116 Pro DX AF 11-16mm f2.8 Gear : Sachtler FSB-4 75 CF, Gini Rig Follow Focus, Lilliput field monitor Tools: FCPX

Locations: Paimpont forest, sometimes said to be the Arthurian Brocéliande, is in the French commune of Paimpont, near the city of Rennes in Brittany. As Brocéliande it had a reputation in the Medieval imagination as a place of magic and mystery. It is the setting of a number of adventures in Arthurian legend, notably Chrétien de Troyes's Yvain, the Knight of the Lion, and locals[citation needed] claim the tree in which the Lady of the Lake supposedly imprisoned Merlin can still be seen today.

Mont Saint-Michel (Saint Michael's Mount) is a rocky tidal island and a commune in Normandy, France. It is located approximately one kilometre (just over half a mile) off the country's north-western coast, at the mouth of the Couesnon River near Avranches. The population of the island is 41, as of 2006. The Mont-Saint-Michel and its bay are part of the UNESCO list of World Heritage Sites.

Iscomorphot 16 mm HELP https://personal-view.com/talks/discussion/4304/iscomorphot-16-mm-help Mon, 20 Aug 2012 10:28:59 +0000 mlysbakken 4304@/talks/discussions Hi! I just received my new Iscomorphot 16 mm 2x, which I recently won in an auction on ebay. I haven't received my lens clamp yet, so I haven't gotten to thoroughly test it, but by simply aiming my taking lens through the anamorphic it becomes clear that its focus ring has no immediately recognisable effect. I believe common practice is to set the taking lens to infinity and rack focus with the anamorphic, but the only option I seem to have here is to rack focus with the taking lens and just leave the anamorphic be (which did seem to work allright in my initial test, but I can't be sure). Since I can't test this out thoroughly without a clamp, I'd be happy if someone could jump in with some insight! Is this common for this particular lens, or have I wasted my money here?

Thanks!

Tue, 29 May 2012 20:02:37 +0000 Roberto 3407@/talks/discussions Having embraced DSLRs after 40 years with a light meter, tape measure and hyper-focal charts, I'd like to try resisting the urge to go backwards and use viewfinder loupes, manual focus and all those things which - after all - really require a team to be done properly.

I see my GH2 with a pancake lens, shooting away while sitting discreetly on a sock-full of rice, or attached to my belt. I've starting to read the manual and find I'm missing out on a lot of what the GH2 can do, automatically, to free me up to work faster and better - not to make a silk purse out of a sow's ear, but to become a more modern videographer.

So, within reason, I'd like to hear from fellow users like me.

Repeatable Focus Moves with Focus By Wire lenses https://personal-view.com/talks/discussion/3344/repeatable-focus-moves-with-focus-by-wire-lenses Fri, 25 May 2012 16:22:35 +0000 bheath 3344@/talks/discussions Here is my little contribution to PV. These focus by wire lenses are maddening. So, I've been trying to finda way to manage repeatable focus moves. Here's where I'm at: Physically superimposed marks on the LCD or monitor. (Stick on) I first tried camera tape strips with pen marks. Not bad but ugly. Also grease pencil and so forth. What I came up with (and could be improved is this: (see photo) screen protectors for cameras and Iphones havee a little scale for cutting with precision, I just cut off the scale and stuck it over where the distance slider appears when you manually focus an auto lens. It's transluscent with marks and numbers. Then I used the focus chart and tape measure and memorized distance for each auto lens. (sort of) It could work for your focus puller, or piss her off. But i like it for hitting a couple of marks without spazzing out on the focus ring. It's something. With the 12-35 pana, it could be promising eh? Photo taken with camera phone looking into the varavon loupe diopter, mounted on gh2... Good Loupe! Thanks Vitaly Let's get 'er in focus dammit!
