Photo Forum / Digital Photography / ZLR Cameras / November 2005fz30 versus fuju finepix s9000

Not as much telephoto zoom. Wider wide-angle zoom. On the flip side, it's a higher-ISO sensor, so the lack of image stabilization can be countered by cranking up the ISO and going to a shorter shutter. It's a pity, though, that no-one has offered a camera with a decent high-ISO sensor AND stabilization. -dms > On Tue, 22 Nov 2005 07:28:52 GMT, David J Taylor > <david-taylor@blueyonder.co.not-this-bit.nor-this-part.uk.invalid> [quoted text clipped - 13 lines] > > -dms I find that I get about a factor of ten gain in shutter speed by image stabilisation - about three stops. The S9000's sensitive area is only 25% greater than the FZ30, so it's not going to be ten times as sensitive. Considering that at the long end of the zoom, the Panasonic is f/3.7 versus the f/4.9 of the Fuji, most of the advantage of the larger sensor will be lost because of the smaller aperture. For significant sensitivity gains, you really need the larger sensor used in a DSLR, and all that implies. Yes, I would also like to see a bigger sensor (perhaps the 2/3 inch size used in the Nikon 5700/8700/8800 Coolpix range) coupled with the f/2.8 aperture of the image stabilised Leica zoom of the Panasonic FZ20. However, I suspect the resulting combination would be much bulkier and heavier than the (for me) almost ideal 5MP Panasonic FZ5.

My recollection is that Fuji claims about 2 stops worth of improvement in their sensor noise/sensitivity performance; it's not just increased collecting area, but a lower-noise sensor technology. The F10 certainly is useful at ISO ranges well above what most other cameras in that class can do. I didn't realize that the S9000 had such a slow lens at the far end of the zoom; that gives back not quite one stop of performance. So I guess the FZ30 comes out ahead in terms of reducing camera shake. On the other hand, stabilization does nothing to reduce blur from subject motion; for that, you need fast shutter speeds, which means either very bright lenses or high ISOs (or both). > Yes, I would also like to see a bigger sensor (perhaps the 2/3 inch size > used in the Nikon 5700/8700/8800 Coolpix range) coupled with the f/2.8 > aperture of the image stabilised Leica zoom of the Panasonic FZ20. > However, I suspect the resulting combination would be much bulkier and > heavier than the (for me) almost ideal 5MP Panasonic FZ5. f/2.8 constant gets pretty big as the sensor size increases. You'll note that Panasonic had to abandon that for the FZ30, and that was only a slight increase in sensor size compared to the FZ20. -dms Does anyone expect an FZ7 in the same form factor and weight as the FZ5 prior to the next photokina? > > [quoted text clipped - 41 lines] > > I don't really think the sensor is any better for noise. If you compare RAW images from both cameras, the noise is very similar up to ISO 400 and the noise above that ISO on the Fuji is so bad to be unusable. The main difference is that Fuji does more aggressive noise reduction in the camera processing, which does reduce noise but also reduces resolution. With the FZ30, you get less aggressive noise reduction which is all you need most of the time and it is your option to do additional noise reduction with extra software if you so choose. To me the noise issue is talked to death on other forums and is really a non-issue on this camera. The bad rap it gets is mostly from reviews which compare the camera to DSLR's costing thousands more (with additional lenses).
