Thanks a lot for your feedback guys as well as the example picture. I know I just got the SLR and just focus on it but it's a bad (or maybe good?) side of my personality that when I get into something new I want to know EVERYTHING. And it sometimes slows me down.
I was also wondering why do they sell those lomo cams for like 300 dollars when you can use that money to get an entry level dSLR or a Nikon F or something like that. Especially since you can find other lomo cameras on eBay for 10 dollars, even though I doubt that they work or something.
Also what is a Pinhole camera ? Is the Vivitar shown above a Pinhole camera ? If I understood correctly there are Pinhole lenses for Nikons like mine ?
