PMW-F3 Performing Extremely Well at -26c!

I’m up, 200 miles North of the Arctic Circle shooting the Northern Lights with a mixture of DSLR’s and one of my PMW-F3’s. The F3’s performance has really taken me by surprise as it’s possible to capture even a very faint Aurora just using the 8 frame slow shutter. Hopefully we’ll get a nice clear night and a decent Aurora and then I can turn off the slow shutter altogether. Either way, this is the first time I have been able to shoot the Aurora with out needing to resort to time-lapse.

The below clip is Timelapse as it does show the motion of the Aurora better. Shot with my F3 using the 8 frame SLS and 18db gain.

Norway and the Northern Lights.

I’m in the process of putting together my equipment for my annual trip up to Northern Norway to shoot the Northern Lights. This year it looks like it will be particularly cold with -28c to -32c forecast at the weekend. I was hoping to have a Canon C300 to take, but that has not materialised and although deliveries are supposed to start this month it looks like it might just be a few days too late. I wasn’t going to take an EX1 or my F3 as I wanted to concentrate on the C300 and Canon DSLR’s, but as the C300 isn’t ready I decided to check out the sensitivity of the F3 at extremes. By using S-Log plus +18db gain I can get 6400 ISO from the camera, but whats truly remarkable is how little noise there is even at this high gain. It’s sensitive enough to capture the Aurora at this level, if we get a very bright display, but for the more normal type of Aurora that we should get most nights it’s not quite sensitive enough. When I used the EX1 and EX3 to shoot the Aurora in the past I had to use +6db with a 32 or 64 frame slow shutter combined with 1 frame per second time-lapse. But the images start to get quite noisy like this and it’s not real time. Now the F3’s slow shutter only goes up to 8 frames but because the base sensitivity is higher, the F3 with +18db gain and 8 frame slow shutter is as sensitive as the EX1 at +6db with 64 frame slow shutter. The F3 is also dramatically quieter. In fact there appears to be no increase in noise using the slow shutter. So, no real need to use time-lapse so my footage will be real time (although with some 8 frame judder, which I can eliminate in post). I’m really excited about this!

As well as the F3 I’m taking a modified telescope tracking head for some time-lapse star tracking Aurora shots with a DSLR as well as a DSLR equipped with a WiFi card so I can set up a automated upload of photos to the web. You’ll be able to view those near live pictures on this page http://www.xdcam-user.com/northern-lights-live-2012/ along with video clips and expedition updates throughout the 12 days of the trip. So please come back and find out how I get on!

PMW-F3 Firmware Version 1.3 Available Now.

The latest version of the firmware for the PMW F3 is now available to download from the Sony Canada web site: http://support.sonybiz.ca/esupport/init.do

The key feature of this update is the ability to now output clean 4:2:2 S-Log from the “A” HDSDi port while outputting S-Log + LUT etc from the Sdi out. Of course you still need the S-Log option to be able to do this. There are also some extra 3D-Link features and support for the new Sony wide angle PL mount lens.

Alan Roberts C300 assessment available online.

Alan Roberts has carried out an assessment of the Canon C300. According to Alan (and I have no reason to disagree) the camera performs particularly well.  You can read the report here. Can’t wait to get hold of mine, but I am hearing rumours that shipping may be delayed a little.

UPDATE:

Reading through the report again and comparing it with his earlier F3 report there are some differences in the way some of the data is presented that I think are a little ambiguous and could lead to some incorrect assumptions. In particular the noise measurements where for the C300 Alan quotes -54db and the F3 -48.5 db, but then the C300 was measured at -6db while the F3 at 0db. Using Alan’s own plots the C300 at 0db is -45.5db. So as expected a tiny bit more noisy than the F3, not less noisy than the F3 as you might first assume from the way the report is written. I am also frustrated by the way in the C300 report the similar RGB zone plate alias results are is noted as a good thing while the similar RGB zone plate results for the F3 were noted as a bad thing.

XDCAM Picture Profiles and setups, also C300 coming soon.

I’ve added a new section in the xdcam-user.com forum for listing details of my various picture profiles. You will need to be a registered forum member to view or comment, but registration is free. I hope to add many profiles to this forum over the coming weeks for many of the XDCAM cameras as well as the new Canon C300 once I start to get that dialled in. I’ve started with my EX S-Log style gamma curve.

Reminder- 3D workshop at ProKit London on January 17th

Just a quick reminder that I am running a 3D workshop at ProKit on January the 17th. This is a one day introduction to 3D production that will cover the general principles of shooting 3D with side by side cameras and mirror rigs as well as a look at how to budget for 3D and make money out of 3D.

Full details here: http://www.prokit.co.uk/index.php?view=events

With countries like China launching state wide 3D channels, 3D is a market that continues to grow. With glasses free TV’s expected to be a reality in the next few years can you afford not to know more about 3D and how to produce in 3D?

Alister’s Product of the Year 2011.

Every year I pick one product that I believe has changed the way I work in some positive way, or improved the quality of the productions I produce. Last year my product of the year was the Matrox MXO2 I/O device which brought low cost HD I/O to laptops and work stations at a very low cost.

This year there have been so many products to choose from. We’ve had cameras, viewfinders, recorders all kinds of gear, but it’s the cameras this year that have grabbed all the attention with a whole fleet of new, very capable camcorders with super 35mm sensors available for most budgets.

The first to market was the Panasonic AF101, followed by the Sony F3 and then the FS100. The new Canon C300 was not available to purchase in 2011, so does not qualify for my award.

The Panasonic AF101 never really excited me. It uses a DSLR sensor which is not ideal for a video camera. But, as anyone that reads my blog knows, I am a huge fan of the Sony F3, so much so that I own 2 of them so I can shoot 3D with them. The Sony PMW-F3 is my all time favourite camcorder. I really enjoy using it, it produces a great image and the workflow is straight forward and fast. Now if I was going to give my meaningless award to the F3, it would not go to the standard F3, but to the F3 with the S-Log option. You see the F3 with S-Log is a different camera again. The S-Log option takes the relatively inexpensive F3 into a whole new league, producing images that rival the Arri Alexa and in my opinion surpassing many cameras costing two or three times as much.

But, I’m not this year giving my award to the F3 or in fact any other piece of kit that I own. Instead my award for Product of the Year 2011 goes to the F3’s little brother, the NEX-FS100. Why? Well I think the FS100 is another great camera, so very close to the F3 in terms of performance, but at a price that makes it possible for many more people to own a tool that is quite capable of shooting a technically very good movie.

I’m lucky enough to be able to afford the F3, but many can’t, the FS100 is extremely affordable and that combination of amazing picture quality and affordability is why it gets my end of year award.

Other close contenders were the Convergent Design Gemini 444 and Atomos Samurai external recorders, both very capable devices, but suited to different applications. The Zacuto EVF and Cineroid Metal EVF also both deserve a mention as my eye’s are not as young as they used to be so a good viewfinder is something I need more and more these days. I can no longer use the LCD without having to resort to spectacles and in the middle of a severe storm or hurricane, glasses are a real pain. I use the Cineroid Metal EVF.

On the software front Apples FCP-X gets my turkey of the year award. Perhaps in the future it will get the full feature set that a “Pro” editing application needs, until then I’m going to be using Avid. The new Media Composer 6 is really nice and a major step forward for Avid as it much more open than it used to be allowing you to use pretty much any I/O card that you want.

So that’s it for another year. I can see that the 2012 shortlist will almost certainly include another camera, the C300 from Canon and a  little birdie tells me that there is a very nice viewfinder coming around NAB time. I wonder what else is in store for 2012?
