Default Just wondering about this saw this in minolta forum

Does the fuji s602z have a 32mb buffer? I was looking around in the minolta forum and there was a post about the difference between the d7hi vs the s602z and one of the difference was that the d7hi has 64 mb buffer vs 32mb.

Oh another thing, does anyone know of a good external flash that i can use with the s602?

As a side note, I'm using the lexar 256 24x compact flash card and it's too slow to capture 640 x 480 vga but it's fast enough to capture 320 x 240 with sound for the full lenght of the card.

Thanks,

That is incorrect.

The FujiFilm model s602 has a 96mb buffer.

The model 602 can burst mode 5 frames/sec at the 6mp High setting(17mb each files). After 5 frames burst, the camera will stall while the images write to the media card so that the buffer can be cleared and ready for the next shot.

if the buffer is that large why is it that the camera swap some files out to the disk when you're shooting if you're shooting at a lower resolution? I wish they would allow that.

But at 96 megs, the fuji fine pix has a larger buffer than the minolta d7hi. WOw.

Does the 5 frame/s burst only apply up to the 6Mp fine mode (ie ~2.2Mb)? In the High mode (ie tiff/18Mb), isn't this camera more limited that what was advertised (ie 20-40s wait)?

Yes the D7Hi does have a 64Mb buffer and it can buffer 5 RAW frames (@ ~10Mb/each), and unlike the s602, this camera does flush its buffer to the flash card while new shots are being recorded !

i think he is assuming the buffer size. the imager is effective 3.1MP which would produce a smaller RAW data file in the buffer the it will process and be interpolated up to the equivelent 6MP size image post buffer on its way to the card like a tiff would. this is fuji's thing.

by assuming a pre processing file size of 17MB x 5 frames= 85MB rounding up to 96MB(overhead)

a 7Hi at 9.7MB(lets call it 10) preprocessing 10 x 5 frames= 50MB
rounding up to 64MB (overhead). 64MB stated by Minolta

Our member jinx is using a Transcend 512Mb 30X CF card and says it's ok for continuous movie @ 640x480. Don't know if he customised the cluster size, or that's out of the box.

That was my question... is it possible? The other thing is the D7 can parse the data out to the memory card while it's taking new pictures, whereas the s602 only flushes the data once this buffer is full.

Can your s602 really do 5 frames @ the High setting (ie 18Mb)? Or the 5 frames only apply to the Fine mode or less... which is really not 96Mb, but more like 32Mb or even 16Mb (@2.2Mb file size)

fuji doesn't state the buffer size anywhere in their tech info for the camera.

The fuji does not interpolate a 3mp image. The fuji interpolates 3milllion sensors. The 6mp image is a result of the diagnol ccd arrangement, that must allow for extra pixels to be inserted into the pattern before any file can be produced. If using the camera in 3mp mode, the camra downsamples the 6mp files to 3mp before saving. The only time this is changes, is when the camera is used in 800 or 1600 iso modes, where it uses multiple photosites for each pixel in order to increase senstivity, thus only allowing a 1mp image file. If you use the camera in 3m mode, or even downsample the 6mp image in external software, about 14-15% of 'real' vertical and horizontal data is thrown away, as confirmed from target resolutoin tests. The data can not be reclaimed by interpolating.

The fuji allows 5frames burst in any image size or compression mode, including TIFF. In single shot mode, the fuji flushes every image to the media card(s) after each shot.
