The Olympus Ni-MH batteries will provide approximately 200 shots with typical usage (half of the images shot with flash/half without flash and minimal use of the LCD monitor).

Yes, the FL-20 Flash (stock #200858) and the FL-36 Flash (stock #260113) are both available accessory flashes that cover a wide variety of lighting needs. The FL-50 (stock #260101) is designed for advanced to professional photograhphers who need the greatest light output.

X total seamless zoom (10x optical/4x digital) on C-750 Ultra Zoom versus 30X total seamless zoom on C-740 Ultra Zoom (10x optical/3x digital) Megapixel CCD (effective) on C-750 Ultra Zoom versus 3.18 Megapixel CCD (effective) on the C-740 Ultra Zoom

The C-750 Ultra Zoom does have the remote feature capability. The remote control (RM-1) is an optional accessory available at dealers or on the Olympus Emporium. The FL-20, FL-36, FL-40 or FL-50 dedicated external flash can be attached directly to the hot shoe on the camera. To use the FL-20, FL-36, FL-40 or FL-50 flash off-camera, you will need a bracket and appropriate flash cable.

The CD-ROM provides a full Reference Manual in PDF format on the CD-ROM. Adobe Acrobat that is provided on the CD-ROM is necessary to view the PDF manual. The printed manual that is included with the camera is a "Basic Manual".

For off camera flash with the C-750 Ultra Zoom, you will need the appropriate flash cable with your aftermarket flash and bracket. Please use the following information as a reference: FL-CB05 Shoe Mount TTL Flash Cable (item #200707) - this cable mounts to the Hot Shoe on the C-750 Ultra Zoom; and the opposite end attaches to the aftermarket flash bracket's flash shoe or to a standard tripod attachment thread (1/4x20).

Suggest to adjust the knob of the charger to make charging current at 6A (the maximum) and charge for 30 mins.

Ni-Cd rechargeable batteries are a mixture of Nickel and Cadmium. The cadmium represents +/- 15 of 20% of the battery weight. They are ideal for most types of domestic devices such as alarm-clocks, calculators, remote controls, torches... Ni-MH rechargeable batteries are a mixture of Nickel and Metal Hydride. They are 2 to 3 times more powerful than cadmium-based rechargeables and they have no memory effect.

Only for the C-770 Ultra Zoom. The FL-20 Flash (stock #200858) and the FL-36 Flash (stock #260113) are both available accessory flashes that cover a wide variety of lighting needs. The FL-50 (stock #260101) is designed for advanced to professional photograhphers who need the greatest light output.

No, you can use a newer Ni-MH charger to charge your old Ni-Cd batteries but you should not try to charge Ni-MH batteries with a Ni-Cd charger. Here's why: Ni-MH and Ni-Cd batteries are chemically very similar and when both are fully charged the battery voltage will start to drop. The Ni-MH voltage drop is much more subtle and more difficult to detect.

What is a battery? Battery, can be any device that stores energy for later use. The word battery is limited to an electrochemical device that converts chemical energy into electricity, by use of a galvanic cell. A galvanic cell is a fairly simple device consisting of two electrodes (an anode and a cathode) and an electrolyte solution. Batteries consist of one or more galvanic cells. A battery is an electrical storage device. Batteries do not make electricity, they store it.
