Laurie, What does it mean that: The D200 and D2X produce a 35mm equivalent first generation capture The film sensor of the D200 is substantially smaller than a 35mm film image, so I guess that is not what it means. So what is the basis for saying this? This whole thing about judging

The DSLR digital camera's mentioned are all the higher end models of their respective manufacturers as well as among the more current models in the pipeline. Their being selected probably has as much to do with the degree of noise and distortion of their sensors as the number of megapixels that

Hi People, I can verify that the front of the 50 1.4 does not rotate. Very nice optics for the money, however don't count on or even bother using it at F1.4, it's a mess. Stopping down to 1.8 improves things out of sight. Mark. -Original Message- From: [EMAIL PROTECTED]

I just noticed your postings, else I'd have weighed in earlier. Your problem may well just be that you have a SCSI adapter that isn't supported by Vista — not all that many are, apparently, and if Vista can't run the card then obviously it won't run anything that's attached to it either. I'd

There are, at least, three different SCSI types with each having its own connector. There is SCSI I, which I believe yours is, SCSI II, and SCSI III. At one point you use to be able to get adapters that would go from SCSI I types of connectors to SCSI II types of connectors; but I am not sure if
