Apart from the 3D attachment, however, the SDT750 has almost the same features as the HDC-TM700, except for one thing: no integrated storage. So instead of on-board flash memory, the SDT750 relies on removable SDHC cards. This is particularly surprising considering the price of this camcorder.
In 3D mode, the top quality mode is HA, which is 1080i Full HD running at 17Mbits/sec and 25 frames/sec. So a 16GB card will store around two hours of footage. In 2D mode, the 1080/50p format is also available, which records 1080p Full HD at 24Mbits/sec and 50 frames/sec, so only 80 minutes would fit on a 16GB card. The SDT750's SD card slot also supports SDXC, so 48GB or 64GB removable media can be used.
However, onboard memory is the only omission. Other than this, the SDT750 has the same comprehensive range of enthusiast features as the TM700, with the lens ring topping the list. In automatic mode, this simply offers another control for the zoom. But enable manual mode, press the camera function button on the side, and the ring switches to operating focus. Press the function button again, and you can cycle through white balance, shutter, and iris, then use the lens ring to adjust each setting. It’s the most user-friendly manual control system available on any consumer camcorder currently on the market.
In automatic mode, you still have some control on tap via AFAE, where a single press of the touchscreen LCD indicates a reference point for focus and exposure. So, when shooting 2D video, the SDT750 has every function an enthusiast might want.
The SDT750 has the full complement of semi-pro physical features, too. There are minijacks on the side for hooking up an external microphone and headphones. Without this, audio is recorded in 5.1 surround using the cross-shaped array on the top, which also enables quite effective zoom microphone and peripheral noise cancellation abilities. There's no accessory shoe built into the camcorder body itself, but as with other recent high-end Panasonics, a flap on the side hides a slot for attaching a bracket housing a standard shoe. So regular third-party peripheral devices can be added.
