The Holga lens for DSLRs bayonets in place just like your usual one, and gives you the opportunity to experiment with unique Holga picture effects. Exactly the same 60/f8 lens as used on the iconic Holga film cameras. Plastic elements and unpredictable optical effects! There are versions for Canon, Nikon and most popular standard size DSRs plus Micro Four Thirds, Sony NEX and other mirrorless cameras.
