Canon 10x loupe and Canon 8x
is very good!
Good for general 35mm photographic work and provides
additional magnification. The combination of good performance and 10x
magnification in the Canon 8x Loupe SPP-31
and 10x Loupe 0039W357
makes it especially useful for
checking the central area of full-size 35mm frames. Loupe 10x is another
magnifier for critical examination of a zyan diameter area of a slide or
negative. The 8x Loupe
allows the photographer to see the full width of a 35mm
negative or slide, even if the latter is mounted, with a crisp and clear image
without any distortion. The Canon 10x loupe
allows you to see an enlarged
portion of the said 35mm negative or slide, almost like twice the size that you
would be getting.
