[Michael Shive] ” know that the EX-3 can handle interchangeable lenses but which ones will fit? Can anyone provide good recommendations on what lenses to buy (macro, standard, telephoto) “
Since the stock lens for the EX3 is a Fuji you can go to the Fujinon web site and have a look at what else is available to screw on to the camera without the need for a 35mm adapter:

[Michael Shive] “Also, I’ve watched Phillip Bloom’s reviews of the EX-3 and Letus Extreme 35mm adapter and am wondering what the advantage of the Letus Extreme is if you can have interchangeable lenses already. Is it just to open the camera up to a wider variety of lenses that will fit? “
Not really. To drastically over-simplify the principle of how 35mm adpaters work, the objective is to reproduce the look of 35mm film. Products like the Letus Extreme have a large mirror inside it that the picture from the lens is focused on. The larger the picture the shallower the depth of field for a given focal length. In essence, the mirror becomes the camera’s imager. With this setup you can have the camera’s zoom set to full wide and still have a very shallow DOF. This is impossible to achieve with the camera alone, even with a good HD lens. The camera then simply records the image on the mirror. It all has to do with imager size and keeping the iris open far as possible.
[Michael Shive] “price is not a big concern. “
It will be. You can spend over a hundred grand for a set of Cooke Primes.
The resident prime lens guru here at the COW is Todd Terry. He’s unique in that he not only knows a great deal about prime lenses but he’s also willing to talk at length about the subject. If you can wait until the next Creative COW Magazine is published before you purchase anything expensive Todd will have an article in there about primes: what they are and how to use them, which ones to buy for various shooting needs etc. Definitely a read worth waiting for.
