Kodak DCS 720x SLR Review
By Movable Type Admin
The DCS 720x accepts all Nikkor F mount lenses. Because the CCD imager is physically smaller than a 35mm film frame the focal length of the lens used must be multiplied by 1.6x (50mm lens = 80mm).
The camera is supplied with an infrared blocking filter which can be swapped out for
an optional high quality anti-aliasing filter (which also has IR blocking) if desired.
In my testing the camera frequently produced heavy moir� patterns when used without the
Nikon's multi-meter finder DP-30 is standard for the DCS 720x camera; it's a fixed eyelevel pentaprism, high-eyepoint type; 0.8X magnification with 50mm lens set at infinity; approx. 100% frame coverage. Interchangeable with Nikon AE action finder DA-30, 6X high-magnification finder DW-31 and waist-level finder DW-30 with limited functionality
The Nikon advanced EC-B-type focusing screen is interchangeable with 12 other optional
Inside the viewfinder is an LCD display that shows the metering system, focus indication,
exposure mode, shutter speed, aperture, electronic analog exposure display, exposure
compensation mark; exposure level indicators, flash ready light LED, aperture direct
readout, focus indicators and focus area indicators also shown
The heart of the DCS 720x's camera controls. Main power switch (if turned past the "on" position it illuminates the data LCD), shutter release, EV override, camera operating mode (Program, Aperture, Shutter, Manual) and focus mode buttons.
The monochrome data LCD displays the settings for these options. Shown here it is
displaying Vari-Program (P*) mode with dynamic focus tracking enabled. The shutter speed
is 1/125 second and the aperture is F7.1
Along the back edge is the Auto Exposure Lock (AE-L) / Auto Focus Lock (AF-L) and the AF-ON button. The Main Command dial is used in conjunction with other function buttons to change camera modes and options.
On the side of the prism is the diopter adjustment knob and the metering control switch.
Metering options are 3D Color Matrix, Center-weighted and Spot.
The flash hot shoe allows you to easily mount external speedlights like
the Nikon SB-28D shown here. You can also connect speedlights and studio strobes via
the PC sync connector on the front.
On the front, below the shutter button is the sub-command dial, this allows you
to adjust the f/stop values, shutter speeds and etc. depending on what mode of
operation the camera is in.
The drive mode dial allows selection of:
Because of the size and weight of the camera, there's a vertical shutter
release and secondary hand grip to make shooting in portrait orientation easier.
Power is supplied by a high-capacity 7.2v NiMH battery pack that fits into the same
compartment as the PCMCIA card slots.
The supplied dual battery rapid charger runs off of either
an AC supply or 12v cigarette lighter cord. One or two of the NiMH
battery packs can be charged or conditioned at the same time. Batteries will be
charged to 80% in one hour, a 100% charge requires another two hours.
On the side is an AC power input connector and an IEEE-1394 "FireWire" data port. The DCS 720x can be operated as a tethered camera (with extremely fast image acquisition speed) in a studio environment. On the back is a 10-pin connector that interfaces the camera to options like a cell phone
Inside of the battery/PCMCIA compartment is a serial port for connecting to a GPS unit or cell phone, settable for data in or data out and 1200 to 38,400 baud. There's also a Video Out port for connecting to a NTSC or PAL type video device.
