I am wanting to buy the Rokinon fisheye lens, I have searched thru the menus and can't figure out how to set the camera to shoot without a lens... how is this done?
You don't need to. There is a setting in the IS menu that lets you set the focal length of the lens for IS purposes. Not sure how useful that is for a fisheye thought. You can also use program or aperture priority to take pictures. If your camera isn't letting you take pictures, either camera and/or lens is malfunctioning.
I have yet to purchase the fisheye, I just wanted to make sure it will work with the E-PL1 before I buy it... thank you....
Other than that, use the A S or M modes, but yep that's it. Twist it on, set aperture, focus, and shoot.
