Other differences between the FZ30 and FZ50 include the addition of SDHC card support, a TTL Flash hot-shoe, 16:9 shooting mode, and the so-called Venus Engine III image processor, but the elimination of TIFF file support and several thousand pixels from the 2.0-inch LCD.
The HVL-F20M is a space-saving, easy to carry new flash for Multi Interface Shoe mounted cameras, that's ideal for brightening up portraits, interiors and dimly-lit scenes.
Other advantages include a lighter magnesium alloy body, an NX power pin-enabled hot shoe for adding an external mic or flash, and a new micro-USB trigger cable.
