But if you have non-standard size slides - or just want to make sure you get to the very edge of 35mm slides - this scanner is ideal. The only reason I don't give it 5 stars is because it is very slow in high resolution - I found 2400dpi was about right for slides. I'm not an expert but even I can tell it is far superior to the previous scanner, with much better rendering of detail and more natural looking colours. The other big bonus is the picture quality.

This way you can even ignore the instruction to scan all slides in landscape configuration. This enables me to set a mask (they call it a marquee) on each slide for the area I want. I switched off thumbnails as I read somewhere that this was advisable, and selected Professional mode on the Epson software. Anyway I played safe and bougght the Epson V500 instead and am very glad I did. I contacted Canon about their Canoscan 9000F and they said I would have to take the slides out of the mounts, though I'm not sure if they understood the question correctly. I earlier bought a dedicated slide scanner, which was quick but cropped my slides quite badly and the quality was not good - too contrasty and harsh colours. In my case in 2'x2' mounts, but larger than 35mm (I think the film size was 828 from memory, but anyway it was about 38mm wide). I am writing this review for anyone who, like me, needs to scan non-standard size slides. Excellent scanner, suitable for non-standard slides
