Okay, with regard to lenses you have a number of options.
There are micro 4/3 specific lenses from both Olympus and Panasonic, which are the standard lenses for that camera.
m4/3 Lenses
Note that two new micro 4/3 lenses have just been announced (today). Including those two that makes 8 lenses. I'm pretty happy, the system's growing quickly.
Announced today were a 20mm f/1.7 Pancake and a Leica branded 45mm f/2.8 Macro.
The 2010 Panasonic roadmap for m4/3 lenses includes:
* 100-300mm f/4-5.6
* 8mm f/3.5 fisheye
* 14mm f/2.8 pancake
No idea what Olympus has planned but I'm sure they'll be bringing out more lenses.
You can mount all the 4/3 lenses on the E-P1 with one of the two available adapters (Panasonic and Olympus both make one). All of these lenses will autofocus and work normally on the E-P1, even if some of them look a little odd given the lens size compared to the camera body. Generally speaking, they'll autofocus slower than the micro 4/3 lenses. This incidentally is one of the big differences between the Panasonic m4/3 cameras and the PEN. The Panasonics can only AF with a subset.
4/3 Lenses
There's a cute little lens/body simulator that lets you see what the combination looks like.
Matching Simulator
If you are prepared to manually focus there's a whole world of lenses available via adapters that all work beautifully. Just off the top of my head I know of people using Olympus OM (obviously), Olympus Pen F, Canon FD, Pentax M42, Leica M and R, Konica, Nikon F, Canon EOS, C-Mount and PL mount lenses successfully. With the E-P1 they all get IS as well of course since that's in camera.
My growing collection includes:
Canon FD 24mm f/2.8
Pentax Takumar 50mm f/1.4
Sun (M42) 135mm f/3.5
Voigtlander 40mm f/1.4 |
