Why? The pros outweighs the cons. A few months ago, I was asked to create a video for a client. This video was to be sent to different countries introducing my country to potential investors. Seems like nothing new? Well, the odd thing was that I am/was a wedding photography by profession. Seems like the powers that are decided it was time for me to move on to the next stage of development. Our economic development board had asked my colleague, a professional event/commercial photog, author of Shimworld, Jan Shim, on who they could ask to do a video that would be different to all the other videos they had seen.

Weeks later, I had been appointed to provide that video. So how does a photographer start doing cinematography? Well, fortunately, for me, I was already pretty much involved in working with Final Cut Pro for the video motion slideshows I was creating for my clients as part of my package. Add to that, I had recently acquired a 2nd hand XL2 as a new toy to play with.

To make things interesting, my proposal to the client was to deliver the content in HDV because I hated the look of SD on HD LCDs and I wanted to deliver something that had a longer shelf life. So a few of us got together and within a space of 3 weeks and two Sony FX-7e later, we delivered a makeshift video for an international meeting called the Brunei Forum held in Singapore. 4 weeks later, my team and I (well.. mostly I) are working on a few new projects and shooting more footage.

Here, the workings and decisive factors for the EX1 came up. We were to fly on a helicopter to gather footage for the Heart of Borneo project, part of a conservation effort to protect and promote the equatorial rainforests here. Having the recent experience with HDV, I knew the codec would not be enough to handle moving footage we were going to get so I decided we had to invest in a progressive HD camera. These were our options:

  1. Canon XL-H1 (i was a Canon still camera user with heavy investment in Canon professional equipment)
  2. Panasonic HVX200 3) Sony PMW-EX1 All three were priced at about the same with the Canon having the least running costs (archival) whilst the solid state cameras were expensive to buy (P2 cards SxS cards , HDD/BLD archives)..

I spent a lot of time looking at various footages, reviews and trawling various forums. Each camera had its own ups and downs.

  1. XL-H1: ve - wide to long tele, MiniDV, Step selectable color temperature, shoulder-mount, low light performance -ve - HDV, not using real progressive chips, 1440x1080
  2. HVX200: ve - film look, Solid state, DVCpro, overcrank/undercrank -ve - 960x576 upscaled, expensive media
  3. PMW-EX1: ve: Solid state, Fujinon lens, f1.9 throughout, XDCAM EX, 1920x1080 native, overcrank/undercrank -ve: unbalanced (hard to hand hold), expensive media

Finally, I decided to go with the EX1. Why? 1920x1080p would be useful especially with Smoothcam and 720p crops. Then the Fujinon lens with the consistent f-stop throughout its focal range (like my L lenses). All I was wishing for next was only to have a selectable color temp from the Canon.

A few days later, after the shooting from the Heli, my choices were spot on. The considerable consistent vibrations from the Heli were smoothed out at 720p crops, the frames were sharp and crisp and the colors recorded (although 4-2-0) were brilliant (customised profiles).

The camera was a bitch to hold for three hours though. I had ordered the el-cheapo should brace recommended by Phillip Bloom but is still in transit. So, to help save my wrists, I attached a monopod with a folding manfrotto QR head on the camera and balanced the left lopesiding by positioning the monopod leg to the right. It actually worked :)

To date, I've still not done much with the Letus Extreme on this cam yet though I already have the achromat and everything else ready. I'll be going off to film deep in the rainforest next week and this is where I believe the LEX and EX1 partnership will shine. The problem is.. as the name says.. rainforest.. lots of rain and moisture. Luckily, I ordered in a rainjacket (camera) and I have existing waterproof bags from the still photography. Wish me luck. Will put up some new ground footage when I return.

David,

Interesting story! I'm a Canon guys myself. I have a Canon 40D and a Canon XH-A1 (Prosumer HD Camera).

By the way, I'm assuming you're using your Canon lenses with your Letus Extreme? Did you know that you can stop down those EF lenses (if you need to)?

By the way, I don't think the f/1.9 of a video camera translates to an f/1.9 in 35mm terms. The f/stop is consistent (which, as you've noted is like the "L" lenses) which is good.

David Cheok    April 21, 2008 12:11 AM

Yeah.. mostly Ls and yeah i know i can stop down but i think its too much of a hassle to take it out, plug in to the body etc.. just makes my sensor dirtier faster. My mk2 doesnt have the sensor dust option of the 40d :( Besides, purpose of putting on the LEX is to shorten the DOF. I'd rather shoot with the Fujinon direct for maximum DOF images because I'd get a cleaner and sharper image than from the ground glass.

The f-stop is relative to the relative focal length. It doesnt matter if its 35mm or 16mm... its just a ratio of aperture diameter to focal length. It would translate to the same in 35mm if the focal length were the same.

I've an XL2 with the std and 3x lens as well.. which barely sees the light (forgive the pun) because I seriously hate the tape work flow and the silly servo driven lens. Canon doesnt seem to like listening to its customers. Even with the new H1s, nothing much has changed.. I'm pretty happy I decided to go with the EX-1 (and pretty relieved too).

Shiv Kumar    April 21, 2008 01:59 AM

Yes shallow DOF is the primary reason for using a Letus35, however, since most of my lenses are f/1.4 - f/1.8 there have been times where I needed more than 1-2 inches of critical focus :). I don't change the aperture constantly (for my kind of shooting) and kind of decide what I'll use and then (rarely) stop down if I want to one time.

I thought I saw a video where in the new H1s Canon has changed the way the rings feel. They are still servo, but very mechanical feeling.

Yes, I'm sure the EX-1 was a good choice given everything I've been learning from Phil's work. I can't imagine anything but tape for the moment but I love the idea of solid state and that each take is a separate file.

David Cheok    April 21, 2008 03:19 AM

For wider DOF, i normally either change lenses or move further away. Would be nice to be able to change though. That's one of the reasons why I'm beginning to accumulate the CZ lenses.

Yeah, the NAB video by FreshDV. The rep said they put in a sensitivity control somewhere but i doubt that would change the feel much and not just that but one of the reasons for full manual control is the stop at the end of the focusing range. I guess some old habits are hard to let go off.

Well, tape is a good archiving medium and it solves the problem of archiving i'm having now with the tapeless workflow. Bluray is still not cost efficient so hard drives seem the only way to go.

Shiv Kumar    April 21, 2008 01:02 PM

I believe it stops at the end, and through the menus you can change the direction as well. It's a mechanical shift of sorts where you shift the ring and it goes into manual mode or something (maybe I'm just dreaming this :)).

David Cheok    April 21, 2008 01:09 PM

Hehe.. think u'r mistaken the EX1's for that..

Shiv Kumar    April 25, 2008 12:39 AM

Bummer. You're probably right. I've been watching too many reviews.

Shiv Kumar, can I rent Sony EX1/Letus Extreme in Bombay?

Shiv Kumar, can I rent Sony EX1/Letus Extreme in Bombay? Or do you live elsewhere and don't have any info? Do Canon EF lenses fit on Letus EXtreme? How do you alter the aperture? On a still camera its done on the body. Appreciate advice/info.

Shiv Kumar    May 06, 2008 12:24 AM

Rafeeq,

Sorry, I live in the US and have been here for the last 10 years and so have no idea whatsoever about renting. But Bombay (Mumbai actually) is where it's happening so I'd actually be surprised if you couldn't rent such gear.

Regards EF lenses and Letus35, yes you can use EF lenses with the Letus35 (all models). In order to stop down the lens you'll need your DSLR with you. On your DSL there is a "Depth Of Field Preview" button right next to the lens mount (on the camera body). When you press this button the lens stops down to the apature setting you've set on the camera. So you press this button and while keeping it pressed dismount the lens. The lens stays at that setting. Pretty cool huh? I happened upon it accidently.

Great story, David.
I like your story and reading about your thought process. Do any of the videos that you have uploaded relate to this story?

David Cheok    May 08, 2008 11:02 PM

Hmm.. am uploading a web clip now. The first commercial project. The clips related to the other projects are the Flight Clip and the Temburong clip. I may not be allowed to upload the final clip consisting of all the footage of the past 6 months once its done though. Assigning exclusive rights to the used footage to the client.
