Hi.....my D90 shows r05 when I press the shutter halfway.....as I search r05 means the buffer have rooms for 5 more pix.....is this means I can only take 5 pix only in burst mode?

One thing I noticed since the r05 appear in my LCD.......the pix count didn't even drop......it always shows 1.0k.....its like I have room for 1k pix in my card regardless how many pix I have shot......

I shot using JPEG.....size of the card is 4GB.......can sumone help me explain why this happening.....do I need to send to SC to check it......thanks

thanks celciuz......that means I can take approx. 5 pix without memory card.....so there is nothing to worry about rite

but then why my pix count didn't even drop when i take pix.......it stay at 1.0k all the time......is this the limit D90 can shows in LCD......I mean the max D90 can shows in its LCD is 1.0k while in actual I can shot more than 1k.......and the number will only start to drop when the remaining size can occupy less than 1k pix??
