Default Best memory card for Minolta 7hi or 7i

Haven't decided which camera yet but do know that the 16M CF card aint gonna cut it. Looking for best compromise of speed, cost, and reliability. What should I buy?
- IBM 1G Microdrive
- 1G CF card (brand?)
- Multiple 512 or smaller CF cards (safety)

Thanks!

Do you plan on using raw output from the camera?

If not then almost any flash card will do, since you'll be hard pressed to tell any speed difference in jpegs, and is also the most reliable. 1G card could be had now for the same price as the microdrive, and you'll also save on the battery. http://www.stevesforums.com/phpBB2/viewtopic.php?t=7082

If you use the movie mode or shoot with raw(or tiff), where the file sizes are larger, the camera internal buffer will quickly fill up and then you'll have to wait between movie clips or shots with slower cards. The microdrive is usually quicker (but not always since the camera gut is the limiting factor). As a reference all D7s takes approximately 11s to write to the microdrive for a raw picture, and can take longer and even double with slower flash cards. In a D7hi you don't have to wait since the camera will accumulate the raw shots up to 5 frames... and you can still shoot @ 3 frame/s in raw until the camera needs to empty this buffer!

Ok, so if I buy the 7Hi with the buffer, the Microdrive loses it's advantage? Let's say I got that right and go with the cheaper and less battery-hungry CF. Do you recommend one 1Gb card or 2 512Mb (for safety).

Not really... after the buffer fills up (ie after 5 frames), the slower cards will still be slower between writes; However, no one ever shoot that fast continuously. Instead of locking up the D7hi is still operable while the camera is writing to memory. (but it's not 5x11s, since the camera already started writing to memory before the 5th shot is completed)

I have used the microdrives for quite sometime, so I might be biais, but I prefer larger flash cards over smaller ones. First I don't have to worry about running out of film, or missing a shot while swapping out cards. Secondly folks leave their cards in the washing machine all the time, you can't do that if it stays in the camera... I only carry an extra set of battery and prefer to travel light! :lol: :lol: :lol:

Don't have one of these nice cams. If it's not on the card, you can work it out from the cam by seeing how many shots are available when it's empty, at a particular resolution setting (check the handbook, there's usually a table giving shots versus card size) the card sizes are scaleable proportionately to the number of pics.

You get (25,49,99,208) on the camera film counter based (64,128,256,512) cards when first inserted in the D7, and this is just the camera estimate. Based on the actual picture and fine jpegs compression your mileage may vary and usually exceed thoses limits: For example with a 1G microdrive, the camera estimate was 414, but I can store up 600 frames and sometime even more... 8) 8) 8)
