That said, individual models may be better. Here are some points to consider: 1) Does the card need to be compatible with other equipment. For example, some laptops and PDAs have SD slots making transfer neater since it is not necessary to hang a card reader off it. 2) Do you want to use the card in other cameras. Most dSLRs use CF. 3)Capacity. CF is available in larger sizes. That being said, most serious photographers (amateur and professional) would prefer to use 2 or 3 cards on a shoot as protection against loss or failure. 4) It is harder to damage the connections on a SD card slot. It is possible to insert a CF card sideways and bend the pins in the reader or camera. My local photolab has about half their CF readers on their kiosks out of commission at any one time due to customers damaging the pins. 5) Some people like the fact that CF is larger because they are harder to lose. -Mike |

I'm glad I didn't avoid buying a Nikon D50 on that basis. Looking forward to getting a 1gig high speed SD Sandisk in the near future. :-) A salesman to be avoided! I have a SanDisk Ultra II SD card (for my Panasonic FZ5, as it happens), but they are a well-known and reliable brand. The 60X/66X speed provides fast downloads to the computer. David Oh but the fun you could have with such a moron. ;-) |

I thought it was bad enough that the salesman I had explained to me that the D70s viewfinder was dark with no battery because it closes the aperture when the battery is removed. It was obvious by the DOF that that wasn't the case and it looked to me like it is the LCD in the viewfinder going dark when power is removed. Looking in the front of the lens confirmed that the apeture was still open. -Mike |

The graphic symbols in the viewfinder are generated by a monochrome LCD similar to the top panel display. -Mike |

Some LCDs darken when they are no longer powered. In the case of the D70S, the LCD has a small signal applied even when the camera is switched off. Removing the battery kills this signal. -Mike |

Yebbut... going back to why I queried what you said: I thought it was bad enough that the salesman I had explained to me that the D70s viewfinder was dark with no battery because it closes the aperture when the battery is removed. It was obvious by the DOF that that wasn't the case and it looked to me like it is the LCD in the viewfinder going dark when power is removed. I still don't see how the LCD displaying the exposure data etc. has any effect on the brightness of the viewfinder. From the context ("It was obvious by the DOF" etc) it seems you were talking about the image not the data display being dark. -- Regards John Bean |
