professional level digital video cameras
- historically, industry standard cinema film is based upon Super 35 (S35) format which is 24.9 x 14mm in 16:9 aspect ratio giving a diagonal of 28.5mm, while the industry standard lens mount is the PL mount
- full frame 35mm such as in some dSLRs is NOT normal for movies
- APS-C dSLRs such as a Canon 7D uses 22.3mm x 12.5mm crop of the sensor for 16:9 HD video giving a diagonal of 26.8mm
- Panasonic's Micro Four Thirds size sensor is a little smaller than S35 at 18mm x 13.5 when used in 4:3 still mode, but uses a slightly larger 16:9 aspect sensor in their GH cameras. The AF 100 pro video camera uses 17.8mm x 10mm in HD video mode giving a diagonal of 20.1mm.
- the 1/2“ Sony EX1/EX3 camcorder uses a much smaller sensor of 7mm x 3.9mm giving a diagonal of 8mm.
- when shooting video, a large sensor offers options of shallow depth of field but a full frame sensor may be too large for many video requirements as the depth of field may be too shallow - one does not always want shallow depth of field in video!
- S35 sensor size is generally accepted as the best compromise and makes it easy for those used to shooting in S35 film to migrate to digital using same lens thinking processes.
- as solid state memory has increased in capacity and data transfer rates, digital video cameras have migrated to solid state memory over the past 10 years replacing earlier digital tape such as Hi-8 (late 1990's) or DVD disc recording (early 2000's).
- if you cannot afford the pro cameras or you want a smaller kit, many of the digital SLR cameras and mirrorless camera systems will provide excellent results (albeit, usually limited to 29min max. or 4Gb max. recording) such as:
- Panasonic GH4 4K video stills camera - the best video features in a mirrorless camera or dSLR in 2014 with 4K HD video
- Olympus OM-D E-M1 - the best camera for hand held video without a rig in 2014 thanks to it's amazing image stabiliser
- Panasonic GH-3 - the best video features in a mirrorless camera in 2013
- Panasonic GH-2 camera - the hacked camera is one of the best HD video cameras in March 2012
- Nikon D800 dSLR - nice 1080p HD video with uncompressed HDMI live video out but still has moire issues and issues with horizontal lines
- Sony NEX 7 - resolution and codec not as good as the GH-2
- Canon 5D Mark III dSLR - poor 1080p resolution equates to 720p
- Canon5DII - full frame but moire issues and resolution not as good as the hacked GH-2
- Panasonic GH-1 camera - particularly if using hacked firmware
- other Canon, Nikon cropped sensor dSLRs - not as good as the above
- Nikon D4 sports dSLR - poor 1080p resolution equates to 720p - need to use 2.7x crop mode to get decent HD video

- compact pocket version of the Cinema Camera with a few changes including electronic control of MFT lenses at last.

BlackMagic Design Cinema Camera
- announced April 2012
- 2.5K RAW Cinema camera, 2.3x crop sensor with Canon EF mount or Micro Four Thirds mount for only $3000!!
- the smaller mount is far more versatile in lens selection than the EF mount!
- at last brings high quality RAW mode to an affordable camera BUT a camera with MANY compromises and issues, plus RAW movie processing will be very costly and time consuming!
- manual focus and manual aperture only (there is aperture control on the EF version but aperture is not displayed).
- has shutter angle and not shutter speed which can be problematic in certain lighting conditions as it limits your options to avoid flourecent flickering
- shooting RAW 2.5K onto a 240Gb SSD will give you about 35min shoot length (in the 10bit ProRes HQ mode you will get about 2hrs)
- the fixed internal battery appears to last about 1.5hrs but you can supply external power
- initial firmware only gives 100%, 75%, 50%, 25%, 10% battery then it just stops working, so using an external battery solution is a must.
- to add an external EVF or screen you need to use the HDSDI port as there is no HDMI out
- mic sockets are 1/4“ plugs not XSL and there is no Phantom power
- rolling shutter artefacts can be problematic
- zebra exposure controls but no inbuilt ND filter
- manual focus peaking does not seem to work well on initial firmware, nor does the camera tell you how much recording space is left on the SSD
- no visual audio meters must rely on headphones
- LCD touch screen is very reflective and hard to use in sunlight, plus it does not tilt.
- cannot format the SSD within the camera nor can one delete clips from the SSD within the camera!
- no 50/60p only 23.97/24/25/29.97/30p
- you will need a very powerful iMac to run the software well to edit RAW movies and lots of disk storage ⇒ shooting RAW becomes very expensive and time consuming
- for $2995 for body only you get 13 stops dynamic range 2.5K sensor, 12-bit RAW, ProRes and DNxHD Formats, 23.98, 24, 25, 29.97, 30p Frame Rates, LCD Touchscreen with Metadata Entry, SDI Video Output and Thunderbolt Port, recording to removable SSD Drives, full version of DaVinci Resolve, its premier color correcting software for Mac and Windows - now that is amazing video quality and specs which will suit the pro videographers out there.
- announced Nov 2012 as an upgraded version of the AG-AF100A
- new features include 10-bit HD output via SDI port, 18Mps data rate, Full 1080/60p recording, new focus assist and 16bit LPCM audio.
