The manufacturer announces a scan area of 24.3 mm x 36.5 mm, which is the standard size of a 35mm negative. What a surprise to see that rélaité the area is slightly smaller although it can not scan 100% of the photo but rather 95%, we must then choose whether you want to lose 2 mm to the right or left, or 1mm each side ... I sent my purchase the same day. This is a defect extended to all units of this model. I highly recommend this product.
