Originally posted by wolfier I set the camera to AF-S, SEL (centre). Using the same Kingston class 6 SDHC, when I point it at the light, it shoots at >4 fps (didn't count precisely, but it should be 5), but when I point it at something dark, it falls to 3 fps or sometimes less.
Yes in low light, it's better to use Manual metering. I noticed a big difference in fps between AE modes and Manual exposure in low light.
The Kingston Class 6 SDHC is rather slow BTW. I received my Sandisk Extreme III 8Gb yesterday and I did make a quick test between the:
1) Sandisk Extreme III 4Gb 30Mb/s edition
2) Panasonic Gold class 6 4Gb
3) Sandisk Extreme III 8Gb 20Mb/s
4) Toshiba Class 4 4Gb
5) Kingston Class 6 8Gb
The first 3 gave roughly the same performance (a rough calculation put them at about 12-15Mb/s).
The last 2 had about the same performance too but were about two times slower. I had about the same kind of performane on the K20D. On the K-m it's less problematic because the buffer is very short and the files smaller.
