Over the many years I have been a photographer, some of my most memorable shots have been with the original Holga 120N. It's not hard to see why -- for such an inexpensive camera one can have a lot of fun shooting and figuring out what the camera can do. It is still a bargain compared to the Lomo Diana F+, and the results are still as unique as ever. However, many folks have left film cameras and want to recreate the Holga "look" on a digital camera. China has responded by producing Holga lenses for Nikon, Canon, and Pentax mount cameras. I have used the 60mm Holga lens in my Nikon D90 and in my Nikon film SLRs, and wasn't too enamored with it as the viewfinder image was very dim. The aperture was listed as f/8, but I think it was even smaller than that, negating some of the very characteristics that make the plastic lenses so fun to use. I am always on the lookout for fun lenses to use with my Olympus Pen E-PL1, and I saw that Holga was selling a version of the lens for the Micro 4/3 mount. The 25mm focal length was a perfect "normal" lens aspect for the M4/3 mount, too. So, I ordered a lens from Holga Direct and it arrived about a week later. For less than $20, too, direct from Hong Kong. Yes, the lens is ALL plastic, but that's the "Holga way."
Here are a few samples. The lens does best in contrasty situations - i.e., full sun. Set your ISO to 400, and you will be good in full sun to partly cloudy conditionS. I use the 1:1 setting for square format Holga-like results, and have been quite happy with it.
