Looking for camera recommendations to meet the following spe

[samed]

Hello:,

Can someone advise on the digital camera to choose to satisfy the following requirements:

- able to do remote frame-by-frame capture (shooting from PC, download directly to PC):
- in a "raw" = uncompressed mode
- with resolution at least 1024x768
- fast transfer, so that the shots can be made with less than 1s interval, the faster the better
- manual focus, manual shutter speed, manual aperture, static color balance
- not involving mechanical movement within the camera
- with inexpensive but high quality macro lenses available, to take high quality pictures of 6mm x 4 mm areas in a full frame size?
- not expensive

Thank you!
