It's a private video. I can't watch it.

It wouldn't be hard to find out! Just leave your lens cap on and record a bunch of 5-second clips starting at the ISO 12800, then enhance the noise in post.

[quote name='andy lee' timestamp='1352386633' post='21311'] very interesting to see this ! thanks for doing this... what picture profile are you set on? [/quote] I should have mentioned. I am in 'Smooth'.

[quote name='pietz' timestamp='1352386028' post='21308'] please QuickHitRecord check that myth of having to step down to get lower noise. [/quote] I already have: [quote name='QuickHitRecord'][color=#282828][font=helvetica, arial, sans-serif]I did a full-range ISO test of my GH2 with the Flowmotion 2.02 settings, starting at 12800 and working my way down to 160. I did this after reading a little more about the GH2 ISO bug. Initially, I had read that if you wanted to use ISOs 320, 640 or 1250, you had to switch the camera on and first go to [/font][/color][i]any[/i][color=#282828][font=helvetica, arial, sans-serif] higher ISO, and then back to one of these three to minimize noise. Then I did some more reading on Personal-View and apparently what you want to do is go to the next ISO increment up, and then back down to the desired setting (so if you want ISO 320, go to ISO 400, then back to 320; if you want 640, go to 800, then back to 640). This seemed to result in a MUCH cleaner image than my initial tests with the first image. The footage is pretty usable up to ISO 1250, at least with the Flowmotion hack.[/font][/color][/quote] It's in the resulting images above as well. I started at the highest ISO and worked my way down to the lowest, accommodating the ISO bug.

Nice footage. This is such an underrated lens.
-
A monitor with peaking will help you nail that sharp focus a lot better than the GH2's viewfinder or LED screen will. If you're concerned about having a problem lens, I'd suggest composing an image with multiple subjects at varying distances, putting the lens in T1.6, and then capturing a rack focus from one extreme to the other. You'll know right away when you watch it.

Haven't heard of that one either, Axel. I will give it a try. Anything for a clean image. In the meantime, this was bothering me so I did a test which I am going to put in a more appropriate thread: [url="http://www.eoshd.com/comments/topic/1299-gh2-iso-tests-rethinking-the-iso-bug-iso-320-cleaner-than-iso-160/page__hl__iso+test"]http://www.eoshd.com...e__hl__iso test[/url]

I haven't seen a side by side test like this so I decided to create one. The video is uploading on Vimeo but I suspect that the compression will make it difficult to gauge, so here are some screen grabs. Please click to view full screen: [center][img]http://www.eoshd.com/comments/uploads/gallery/album_14/gallery_18451_14_61391.jpg[/img][/center] [center]*I should also add that each stripe was sampled from the center of the image.[/center] [center][img]http://www.eoshd.com/comments/uploads/gallery/album_14/gallery_18451_14_298073.jpg[/img][/center] [center][img]http://www.eoshd.com/comments/uploads/gallery/album_14/gallery_18451_14_670092.jpg[/img][/center] My previous tests concluded that ISO 320 was the sweet spot. However, when I did the same test this time, ISO 320 gave me a lot of macro blocking. Bizarre! I don't believe that I changed anything between last time's test and this one. To me, these images suggest that you'd be best off parking it in ISO 640 and leaving it there. It's also interesting that different ISOs seem to have different color casts.

[quote name='kirk' timestamp='1352323640' post='21256'] I thought the safe ISO thing (if you don't want to step down to your top row ISo setting) is to avoid the top row alltogether??? I shoot mid row now and have had much cleaner results. And if I need 160 I step down to it... And Re 4: Avoid underexposing, especially in high contrast low light scenes... help a lot. [/quote] Wait, what? I have not heard this before. I was certain that I read that the increments of 160 were the way to go, like the Canons. I think that I also found a test online that verified that (of course, I cannot find it now), which is why I never the other rows a second thought. Do you have any examples?

[quote name='JimJeffBeam' timestamp='1352321594' post='21251'] Some of the gear rings say 45mm-100mm lens, but then others don't say anything. Will this one work with my gh2 20mm or my hyper prime 12mm? any suggestions what to get for a wider lens? or maybe a gear ring that can do all sizes? [url="http://www.amazon.com/Adjustable-Flexible-Follow-Focus-Lever/dp/B00A2LYWMO/ref=sr_1_7?ie=UTF8&qid=1352321555&sr=8-7&keywords=adjustable+flexible+gear+ring"]http://www.amazon.co...xible gear ring[/url] [/quote] Looks like that one is adjustable to fit most lenses. See the part of the strap that sticks out? That's excess gear tread. If you want to err on the side of caution, I recommend that you ask the seller how long the gear tread is and then the math. But I doubt that you'll be shooting with any lens with a diameter of more than 72mm.

3. Not that I am aware of. 4. The way that the GH2 handles different ISOs is a bit tricky. Stick to the top row and you'll get a cleaner image. Also, take a look at this thread: http://www.eoshd.com/comments/topic/1299-gh2-iso-tests-rethinking-the-iso-bug-iso-320-cleaner-than-iso-160/

New MFT camcorder from Panasonic, rebuilt from scratch!
QuickHitRecord replied to Axel's topic in Cameras
[quote name='KarimNassar' timestamp='1352301502' post='21235'] According to a couple french websites (thanks to digitalmaster for the links) this camera costs tax [b]not[/b] included..... ... ... ... 5'295 usd LOL this must be a bad joke. The french blogs must have messed up now way it is that expensive. sources posted by digital master: [url="http://www.magazinevideo.com/news-628.htm"]http://www.magazinev...om/news-628.htm[/url] [url="http://www.focus-numerique.com/panasonic-ag-af101a-passe-hdtv-1080-50p-news-3734.html"]http://www.focus-num...-news-3734.html[/url] [/quote] I am so confused by this "offering". How has Panasonic been conducting their market research lately? Why don't they read the forums? -
A follow focus is designed to make the focus pull even smoother and more precise by adding more gears between your hand and the focus ring on the lens. Most follow focuses come with markable discs so that you (or your dedicated 1st AC/focus puller) can design and execute very precise focus pulls.
-
Actually, for your purposes, I agree with Andy as well. If you really get into video work, then you should look into a follow focus. But for now, this solution will work for you. The strap wraps around your lens gear ring and you focus by manipulating the handle. Because the tip of the handle is further away from the lens, you have to turn it more to achieve the same focus pull but this will also stabilize your focus pulls. It also takes the focusing action out of your fingertips, which can only move the focus ring so far, and puts it into your wrists and arms like this: [center]http://youtu.be/OAo-ZF-nXF4[/center]
-
Definitely look into it. I use an Edelkrone FocusOne Pro and zip tie gears from Half Inch Rails. You'll also need a 15mm rod system to mount the follow focus, but they can be had for cheap from eBay.
-
Get a follow focus and a monitor with a good peaking feature like the SmallHD DP4 or DP6. The focus assist feature will help you nail focus every time.

I am intrigued by this. The shot with the titles over it is gorgeous. I used to have an LA-7200. I struggled with diopters. This was the best solution that I found: http://www.eoshd.com/comments/topic/1212-panasonic-ag-la7200-diopter-mounting-solution/

Rich and I both had this idea, but if he's able to get the FS700 rigged up, it will look a lot cooler in slo-mo. For now, here is this: [center][media]http://vimeo.com/52820545[/media][/center] I would not recommend doing this will full, well-shaken cans like I did (to be fair, I did not shake them, but I did not think that the road would be so bumpy). I am still trying to clean the syrup out of my achromat. Still accepting submissions if you have one.

Convert footage to ProRes automatically with folder actions! (OSX) FIXED!
QuickHitRecord replied to galenb's topic in Cameras
That would be awesome. 2x is the most common, followed by 1.5x. I can only speak for myself, but I am running an older iMac so I typically edit squeezed files. -
Convert footage to ProRes automatically with folder actions! (OSX) FIXED!
QuickHitRecord replied to galenb's topic in Cameras
Without getting too much into it with the anamorphic forum but a click away, it depends on the stretch factor of the anamorphic lens. There's 1.33x, 1.5x, 1.75x, and 2x. Multiply that by 1920 for stretch and divide 1920 by the number for squeeze. If you are interested in anamorphic shooting, I recommend picking up Andrew's book. It's a good place to start. -
Apefos has asked me to clarify that the lens is solely based on his own design and he has been the only one to work on it -- all that he has received from others is encouragement. it is quite an accomplishment. Here is another clip: [center][media]http://vimeo.com/52730117[/media][/center]

QuickHitRecord replied to galenb's topic in Cameras
@galenb It can be either. STRETCHING the footage gives you a near 2K image, while SQUEEZING the footage is a lot more edit-friendly. @Axel I use Compressor for my anamorphic workflow. I was just curious to see if two steps could be reduced to one. -

QuickHitRecord replied to galenb's topic in Cameras
Galen, this is great. Thank you for sharing this. Is there a way to modify this to stretch/squeeze anamorphic footage automatically as well? -
In the thread, Alan is given credit as a collaborator. Pretty cool.

I have been following the development of a new anamorphic lens created by Personal-View user Apefos, and today we finally have the first footage: [media]http://vimeo.com/52515544[/media] It is remarkable to me what a lone person can overcome and accomplish with a little conviction and a lot of patience. For more information, see the thread at Personal-View.
