Canon 10x loupe and Canon 8x loupe 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.
