Holga's are made from all plastic, including the lens. As such no two Holga's are the same, no two give you the same results.The camera has a 60mm f8/f11 plastic meniscus lens and results are unpredictable. Some cameras give you crystal clear results but others often have distorted results. The cameras use zone focus and have a non ttl viewfinder so you never know if you are in focus or not. Because of all that it is not uncommon for fans to multiple copies, because each camera will give a different result.
The 120n takes 120 medium format film. The camera is supposed to come with two inserts(called masks), one that gives you a 6x6 negative and one that gives a 6x4.5. The 6x6 gives you 12 exposures and the 6x4.5 would give you 16 exposures. The camera I bought only had the 6x6 mask, I can get myself the 6x4.5 mask through B&H camera store's website.
I shot a roll of Ilford Delta 100 black and white film through the camera. The results were interesting. Some of the photos are pretty clear while others were blurry. Each shot had a bit of vignetting around the edges of the shot, like a frame. It gives the shots a unique look.
I am looking forward to shooting more rolls through this camera, different types of film and maybe even some colour film. It is one of those cameras that the anticipation of what the shots will look like, that make the camera so fun to shoot with. It is so basic, set the zone focal length and shoot. There is no aperture or shutter speed to set, no exposure compensation to worry about. Just get out and shoot and see what you get. It is not a camera that I would use often, or use for projects. But if I am looking for a fun camera to just get out and shoot some cool shots, maybe something a little artistic than this may be the camera I grab.
