AP Slide Viewer brand_Toyo A basic manual focus teleconverterThis is an excellent illuminated single slide viewer for 35mm slides. Just push a slide into the slot and the viewer's light will turn on; release the slide, and the light turns off. That's about it! It is not the cheapest viewer out there by far, but it's the best one we've found. Uses two AA batteries (not included). Made in Spain.
