The SF-210 from Nikon is an automatic slide feeder that lets you scan batches of up to 50 slides. The SF-210 accepts slide-mounted 35mm film up to 1.5 millimeters in thickness and is designed to work with Nikon Super Coolscan 5000 series scanners. Converting slide film has never been easier. Simply place your slide-mounted film into the slide feeder and insert into your Nikon Super Coolscan 5000. The SF-210 also comes backed with a one-year limited warranty.
