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. The display has a grid which can be switched on as well as focus and metering graphics. The liquid crystals actually cover the whole viewfinder. I'm not talking about the display along the bottom of the viewfinder although I expect its all part of the same LCD panel. -Mike |

It was hard to grasp without seeing one but now I understand exactly what you mean - you're looking through an overlaid LCD which can of course effect the image brightness. -- Regards John Bean |

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. Good point, though the SD card readers built into laptops are slower than a Cardbus 32 bit reader that you put into the Cardbus slot of the notebook. 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. One issue with SD is the problem with the in-camera card readers. We've seen SD cameras that cannot write to any SD card because the camera 'thinks' that the card has been write-protected. It's a funky mechanism that reads the position of the little tab for write-protection. CF has no mechanical write-protection. |

One that works on commission and the commission is higher on the SD... :-) Well ... he was apparently pushing the CF, not the SD, so reverse that. Or -- the commission is higher on the camera which uses CF instead of SD? (E.g Nikon D70s vs Nikon D50 for two otherwise quite similar cameras.)

Thanks Mike--a salesman was trying to sell me a story that the CF memory gave better quality photos. 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. :-) I wonder why Nikon chose a different media for the D50 than they use in all their other dslrs? |

I'm glad I didn't avoid buying a Nikon D50 on [ ... ] I wonder why Nikon chose a different media for the D50 than they use in all their other dslrs? At a guess -- two reasons: 1) The D50 body is smaller, so the SD drive takes up less of the camera's internal volume, perhaps resulting in pretty much the same amount of crowding. (You can't shrink the mirror/shutter assembly without shrinking the sensor, which they did not do.) 2) As the D50 is intended to be an entry-level DSLR, it might be that they expected more of their new customers to already have SD cards from previous digital P&S cameras. My personal preference is for the CF size for several reasons which have been documented earlier in this thread (or another on the same subject.)
