EX3 With NanoFlash Camera rig.


I have been asked to show how I mount my NanoFlash on my EX3 so below are a couple of pictures of the full rig with some details of some of the various items that I use.

1. This is my Petroff 4×4 matte box with bellows hood. I love the old fashioned style bellows lens shade as you can adjust it in and out very quickly to eliminate stray light. A french Flag can be added if desired, but I find in most cases that the bellows shade is fine. Stray light causes reflections both between filters and within the lens, this can reduce contrast in the image so a good lens hood is essential for getting the best pictures. The Matte Box has 2 rotating filter holders. I often use some very gentle blue or grey grads to help with bright skies.

2. The standard EX3 lens. This lens is a remarkably good lens. Keep it between F8 and F2.8 for best results. The sweet spot is F4. Never use the Iris at F16 or F11, your pictures will be soft due to diffraction limiting. This is not a lens fault but something that would happen with any lens and 1/2? sensors (it’s even worse with smaller sensors). The beauty of the standard EX lens is that it incorporates automatic chromatic aberration correction which means no nasty blue or purple fringes around areas of high contrast.

3. SxS Cards. Even though I was one of the first people to work out how to use low cost SD cards with the fabled Kennsington Adapter I still use SxS cards. The reason is simple: reliability. If you look around the forums you will find lots of people having issues with SD cards. For example a wedding videographer that lost a large part of a service he had shot. If he had used SxS then that just would not have happened. I am a professional and my reputation is vital. That reputation could easily be destroyed if I came back from a shoot with nothing but corrupt data because I had tried to cut corners.

4. Kata Camera Glove. Protects the camera from everyday knocks and bumps as well as unexpected rain or dust.

5. The Cheek Pad. I know many EX3 users don’t fit these. It looks flimsy, but in use it’s strong enough and it really helps to stop the cameras tendency to want to tilt to the left. It makes the camera much more stable and really is worth trying.

6. Convergent Design NanoFlash. This incredible little box allows me to record from the HDSDi output at upto 160Mb/s long Gop. At 100 Mb/s you can’t tell the compressed from the uncompressed. By shooting with this I can grade and color correct my footage, make dubs, go multi generation without seeing any drop in quality. It also means my footage is accepted for HD broadcast by the BBC and the majority of other HD broadcasters. The EX 35Mb footage is good, don’t get me wrong but the 100Mb is sweet. It uses inexpensive Compact Flash cards and by recording to both SxS and the Nano at the same time I can be sure that even if I were to get a card failure I have a backup.

7. IDX V-Lock batteries. One of these will run this rig for around 5 hours. I am also looking at getting some of the Swit EX batteries with the Power-Con/D-Tap out to run the EX and NanoFlash, but by putting the battery out behind the camera the overall balance of the rig is improved. In fact without this larger battery the matte box tends to make it very front heavy.

8. Quick release shoulder pad. This is a home brew affair that incorporates a shoulder pad the V-lock battery adapter and NanoFlash or Radio Mic mount. It can be removed without tools in seconds. Perhaps one day I will get some Zacuto rails or similar, but they are rather expensive and this setup works very well for me.

9. Sony ECM-680S. This is a nice Stereo/Mono switchable gun mic. It is great for capturing nice stereo ambience and effects sound. Flick the switch and it becomes a useful interview mic.

10. DM accessories EX3 reinforcement plate. This is a MUST HAVE item. It provides you with a much stronger tripod fixing with both 1/4? and 1/2? threads as well as a host of other threaded holes for various applications. It makes the camera feel so much more solid on a tripod. I really can’t recommend it enough. below this is a cheap, Indian made Matte Box rail kit. It works, but again I could really do with some Zacuto rails or similar.

11. Chamois leather viewfinder cover. Much nicer against your skin than hard rubber. Also absorbs sweat and moisture which helps prevent the viewfinder from fogging. Another option is a small sweat band.
