I took a roll of film on my flies the other and not one of them turned out. All blurry. What's a good camera to use when taking those close ups with spending a lot of money? and I mean cheapest one you can find :dunno
SLR film cameras usually come with a 'normal' 50mm lens which commonly doesn't focus any closer than about 1 meter. Point and shoot autofocus film cameras are about the same but often produce worse pictures due to the difficulty in getting the focus area properly set.
With an interchangeable lens film SLR you'll need to buy a special 'macro' lens that'll let you focus down to just inches from the lens.
Some digitals have a macro setting that achieves the same thing. My Canon S30's macro feature is a pain in the ass to use but I heard good things and seen some teriffic images from some of the new Nikon Cool Pix models.
Bottom line is that to get good close-up pictures of flies, you're probably gonna have to spend some dough.
What kind of camera are you using? If it's a regular ol' point and shoot, you might be out of luck.
If you have an SLR, you have several options.
Probably the cheapest would be a set of diopter lenses. They usually come in a set of 3 and screw onto the front of your normal lens where filters go.
Another option would be an extension tube. This is a hollow spacer that goes between the lens and the camera body. But, it needs a male and female camera mount on each side. This effectively turns your regular lens into a macro lens.
The third, and best but most expensive, is to get a dedicated macro lens. This is a lens whose main pupose is close-up photography. If you're doing a lot of this kind of work, it might be a good investment.
For a the best close ups you have to use a
bellows with an SLR, or another professional
grade camera - wish I had a bellows, it's
amazing what you can do with them. A good macro
lens is the next choice.
