    Re: epson 750 pro

    My assumption is that the lens may have two fixed points of focus, activated by the switch from reflected to transparency mode. But, I don't know that as a fact, and haven't actually tried to verify my theory.

    If you're scanning negatives of odd sizes, I think you'd either have to make your own holders or use the wet-mount tray. Note, however, the tray is not big enough for an 8x10, so I plan to make my own substitute.

    Hi Again,

    I hadn't found (or missed) the photo-I review mentioned in an earlier post.

    Here's the link:

    http://www.photo-i.co.uk/Reviews/int...700/page_1.htm

    It cleared up most of my gray matter.

    Still want to read more feedback on the 750.

    Thank you.

    Randy

    You mention that Epson includes mechanical step wedges to raise the film holders to optimize the scan. Are they included with the 700/750? Or has this problem been eliminated?

    Do you have to wedge prints to achieve the same optimized quality? I hope not. If so, we need to move on to another scanner with a greater depth of field.
    The way it seems to work with epson is that the focal point is a bit higher than the glass, and the scanners have plenty of depth of field for getting great scans from flat art placed on the bed.

    However, for the higher standards most people have for scanned film, it's usually worthwhile to raise the film to the precise focal point.

    Film scanned at the plane of the glass will look good ... it won't immediately look out of focus. but in side by side comparisons with a scan done at the actual focal plane, you'll see a quality difference.
