Features of the HOLGA 40th Anniversary "HOLGA120GCFN Photography Comparison Set" 1) Standard glass lens and 1 plastic lens included. The fun of HOLGA is the sharpness of the center of the image and the perimeter of the image. Glass lenses can express this feature even stronger than plastic lenses. The stopper on the lens block is loosen, so you can change the lens while shooting. You can compare the same subject with glass lens and plastic lens. 2) Close-up up to 60cm By loosening the lens block stopper, you can pull the lens block further before the minimum shooting distance of 90cm. However, please be aware that if you try to take a more close-up image than 23.6 inches (60 cm), the lens block will fall off from the body. The helicoid is divided into 3 sections, so please wear the distance icon in place. Please adjust the lens infinitely to prevent shedding.
