Looking for some advice on a new (or used) lens for my camera. I'm planning on spending my spring break dog-sledding and viewing some northern lights in the Northwest Territories, so I wanted to get a lens for my camera to take advantage of the events. I have a fish eye lens, but it's kind of a cheapo- ebay lens, or its not suited for my camera, I don't know. Some larger scale landscape photos have turned out ok with it.
Camera: Olympus E-420
Current lens: -Zuiko 14-42mm
-Zenitar M2,8/16 Fisheye (made in Russia)
I don't know all that much about this camera or the 4/3 system, but I figure I need a lens adapter to fit the popular lenses to it. The current lenses I have fit the camera with no adapter.
Any suggestions are welcome, I was thinking a wide-angle lense might be appropriate. Not looking to spend much more than 200-250, so used seems like a good option.
