will have joy with this device. Since the slide holder can not be fixed, each slide has to be re-aligned. Surprises can arise when the lens when triggered even refocus while twisted the front lens. Then the slide is also duplicated wrong. Together with my Canon 55-200mm (kit lens, filter size 52mm) were made to the image edges towards blurring. The Tamron 18-250mm (Filter size 62 mm) has been joined by significant vignetting. My expectations did not meet the unit.
