I do love the website! As for the colors, that's not a product of the camera but of the film. Get yourself highly-saturated film, and you'll get the same effect.

I do get what you mean about carrying around the SLR all the time. You might consider getting a cheap film camera you don't mind dragging everywhere -- I own 3 Pentax K-1000 bodies, a "standard" for decades... It's fully manual, and although earlier K1000s didn't come with a light meter, most have a little needle that indicates exposure.

Of course there are many versions as it was produced for decades. Most (if not all) are extremely rugged, though not really weatherproofed. However, you can buy a body with a 50mm lens for $50 or less if you shop for a month on ebay. at $50, I don't have any qualms about getting it a little damp! You also have the advantage of interchangable lenses -- decades of used lenses that are cheap used...

So yeah. My advice? Shop around for a used K-1000 with a 50mm lens. Add lenses or filters or flash to taste. You'll end up with a MUCH superior product that's easily as "disposable" as the lomos. Only downside is that it'll weigh a tiny bit more -- especially the all-metal versions (one of mine seems to have a plastic housing that cuts down the weight considerably). But with a 50mm lens, it's not really that cumbersome.

Then go to the Lomo site and do everything they do with YOUR camera!. Have fun, get the shots, and you'll end up with a decent backup system to boot!
