While I await delivery of my new camera, i was just thinking if there is any merit in going for CF over xD for memory cards. Ive ordered a 1GB xD card to get me started, but as the camera also accepts CF is it a better option? As for the connectivity, either CF or xD is fine for the transfer of images as I have media readers for both.

Since I'm using the Canon 300D, I have no choice but to use CF.
But I remember when I was buying a memory card for my PDA, he mentioned that generally CF is faster than other cards, but since it's bigger in size, it's not popular among manufacturer. I don't know how true is that.
I found a site http://www.memorex.com/downloads/whitepapers/WhitePaper_Reference_Guide_Flash_Mar06.pdf but I have no time for it now (working )

Thanks for that Link - Yup, Speed would be fairly important I think especially for RAW given their size (18mbs each apparently on the fuji) :S
The 300D looks like a superb camera. Canon always get good reviews dont they?
8 hrs ?????
Must have been using a pinhole "lens"........and a dang small one at that !

I routinely use multi-hour exposures on dark nights. 8 hours is very doable at ISo 100 at F22. Digital can't handle it with off-the-shelf cameras due to infrared bleed from the sensor amplifier. That and the battery crashes after holding the mirror up for an hour or so.
I built a rig to use a car battery, inverter and a Canon AC supply on a Canon 5D but I get infrared bleed after about 2 hours.
Hi Rikk, I'm not sure whether it the same issue, but we remove the infrared filter for astrophotography purpose - to obtain the natural colour.
What does infrared bleed mean?
Normally we don't do continuous long exposure unless it's on film. For digital astrophotography, we do short exposure (20-60 secs) and take multiple shots (10-30) and stack them.

The infrared bleed comes from the amplifier adjacent to the sensor. It is a red circular fog creeping in from one side.
I prefer to do my long-exposure stuff on film still. It is the only thing I still shoot on film though.
Hi RIkk, thanks for the info. Will read more on that.
