Featuring a stylish; easy-to-handle design; the AG-AC90 AVCCAM HD handheld camcorder captures native 1920 x 1080 resolution images and records in 1080/60p; 60i; 30p and 24p; as well as in standard definition (480/60i) in 60Hz.
The AC90 debuts a premium professional AVCCAM HD recording mode; the PS mode (28 Mbps; 60p only); and also records video in the PH mode (average 21 Mbps/Max 24Mbps); the HA mode (approx.17 Mbps); and the extended recording HE mode (approx. 6 Mbps) as well as SD (at 9 Mbps.) Shooters will find invaluable its wide 29.8mm to 357.6 mm (35mm equivalent)12X optical zoom lens with three independent adjustable rings for zoom; focus and iris for a wide viewing angle; and Panasonicâ€™s exclusive Nano Surface Lens Coating that reduces ghosting and flares.
The AC90 includes; a five-axis image stabilizer that dramatically improves stabilization for hand-held shooting; a 4K2K pixel shifting technology for a sharper image; and an Intelligent Zoom Auto that provides seamless digital zooming up to 25X magnification while minimizing decreases in resolution. The standard zoom length is 12X.
With two SD slots for continuous recording; the AC90 can record up to 12 hours on two 64GB SDB cards in PS mode;. (There will be a skip in the video as it changes to the second card) The two slots can also be utilized for simultaneous back-up recording. Additionally the camera can be set up to record video on one card and the Stills on the second card.
Though not an interchangeable lens camera, the lens it comes with is quite capable. The fast lens (f1.5 fully open) allows loads of light to hit the sensor, always a good thing - particularly in low light situations. Optical zoom is a respectable 12x and controlling it the middle of the three rings on the lens barrel or one of the two zoom rocker switches - one at the top of the handle and the other atop the hand grip on the right side - each near its own thumb-accessible record button. The rocker switches are right-now responsive, while the zoom ring is much smoother, allowing you to ease in and out and vary the speed of your zoom.
The focus ring allows you to achieve manual focus while Push AF (assigned to a User button) lets you switch temporarily to auto for a quick assist from the camera. Two buttons on the control panel affect your focusing options: Focus A/M switches between auto and manual focus, while Focus Assist outlines the areas in focus with red (the only color choice). Older eyes will find this a very welcome feature.
There are no neutral density or video gain switches or dials on this camera. These tasks are instead integrated into the iris ring. At one end of the exposure spectrum, the iris is fully closed. It begins to open at f11 and continues to open wider until it reaches f1.5 - fully open. At settings wider than f2.8 neutral density filtering is automatically applied in increasing degrees. Continue to rotate the iris ring beyond fully open and gain is applied in 1dB increments up to a maximum of 30dB. The tradeoff here is that as gain is added, noise increases. The AC90 however has some of the cleanest gain we have seen, with increases to 20dB being relatively noise free and very usable. Exposure assist features include a Zebra button on the control panel with two zebra settings and a marker function.
The placement of the LCD represents an interesting design change to this otherwise familiar format. Most LCD panels fold up flat against the side of the camcorder, covering frequently used buttons. The AC90’s LCD panel slides out from a crosspiece at the front of the handle then rotates vertically up to 270 degrees for high and low angle, or self, shooting. The high-res panel is sharp, crisp and touch sensitive. The touchscreen controls menu and playback options, all of which are nicely responsive and easy to navigate. The retractable nature of the LCD provides a high level of protection to the screen when safely tucked away, but care should be used when the screen is out and while putting it away, so that it isn’t struck or forced at an angle.
Attention to Audio
Of course, a huge part of the success of any video production is the quality of its audio and the AC90 includes numerous options to enable you to achieve that goal. Its built-in mic is capable of 5.1 surround sound or two-channel stereo capture with both focus and zoom functions.
Although this audio is certainly usable, we know it is better to get the microphone closer to your subject than the camera as often as possible. To this end, the AC90 includes two XLR inputs on the right side of the crosspiece at the front of the handle. Opposite the inputs, at the other side of the crosspiece, is a hinged plastic cover, housing line/mic and phantom power switches. A second cover at the rear of the control panel protects the input source selection switches and gain control dials. These dials can be accessed through holes in the cover, without having to open it first, for gain adjustments on the fly.
Three 1/4.7 type MOS, 1080p image sensors (one for each primary color - RGB) combined with highly sensitive backside illumination (BSI) and dense pixel shifting technology delivers extremely sharp pictures without aliasing, excellent color reproduction and a broad dynamic range. Shadows and highlights are right where we like to see them. The AVCHD format records at a color sample ratio of 4:2:0[MH2] - nice for high quality chromakey work.
The Intelligent Auto Mode and Hybrid Optical Image Stabilizer (OIS) will likely appeal to run-n-gunners in particular. The auto mode automatically detects shooting conditions and adjusts every parameter accordingly. Of course, we like our manual controls, but for those times when it’s shoot it or lose it, Intelligent Auto Mode does an excellent job. Hybrid OIS combines the best of both optical and electronic approaches to image stabilization, analyzing motion along five axes for excellent results - some of the best we’ve seen in fact.
In addition to awesome video images, the AC90 also takes very nice 3MP still photos, recording everything to SD cards. With dual memory card slots, your recording time can be extended by automatically switching to the second memory card when the first becomes full. Backup recording records the same material to both cards simultaneously for safety. And, if at any time one card fails, recording continues on the second card so you don’t lose the shot.
With excellent image results, reasonable pricing, all these features and too many more to mention, the Panasonic AG-AC90 has a lot to offer enthusiasts and prosumers alike.
