The camera also includes an "extended optical zoom" system providing greater optical zoom ability when shooting at lower resolutions, giving up.3 zoom at 3MP.
The zoom and focus mechanism is internal: the lens does not physically extend beyond the camera housing when focusing and zooming.
Zooming while recording movies is supported since the zoom is manual.
High-speed SD cards up to 2 GB and sdhc cards up to 32GB are supported.
Several different auto-focus modes are available.RAW files are recorded in around three seconds with fast SD cards, which is one of the best results among non- digital single-lens reflex cameras ; however, there is no RAW buffer as on many digital SLR's.The main differences are: Higher resolution.1-megapixel CCD, venus Engine III processor (with its characteristic unusual noise reduction algorithm).0-inch flip-out 207k high resolution LCD (FZ30 has 235k).Unlike its predecessors, the FZ50 does not support tiff format.
Apertures from f/2.8 to f/11 are supported, though the largest apertures are not available at high zoom levels (f/3.7 at full zoom).
Startup is under one second, as the lens does not need to be extended.
Essentially, this just crops the center out of the image in-camera, but can be useful for metering and framing purposes.
