Now that I have a Panasonic GH2, you might want to know which lenses I have bought.
Here is a run down of the spending so far.
Panasonic Lumix G 14mm F2.5 ASPH – Excellent wide angle and very tiny for low light. Smallest lens for m4/3rds. Small enough to coat pocket my GH2.
Panasonic Lumix G Vario 14-140mm F4-5.8 Mega O.I.S. – Great range for daylight shooting with O.I.S. (image stabilization)
Panasonic Lumix Leica DG Summilux 25mm F1.4 ASPH – Spectacular, now lives on the camera.
Panasonic Lumix G Vario 100-300mm F4-5.6 Mega O.I.S. – Needed for birding and telephoto work.
This makes a small lightweight package for my camera bag. Considerably lighter than my old Canon system.
What is not missing is a replacement for my Canon EFS 10-22mm F3.5-4.5. I have just purchased the Panasonic Lumix Vario 7-14mm. It is spectacular and is the best zoom lens for video right now because it does not breath and has a constant aperture. We need a large constant aperture medium zoom with O.I.S. Rumor has it that Panasonic is listening. Well their AG-AF100 needs it too.
Olympus M. Zuiko Digital ED 45mm f/1.8 Lens for Micro Four Thirds Cameras – Extremely small and light weight short telephoto.
I already had some OM glass so I bought a OM to m4/3 mount. This way I can use some of my old glass.
OM 50mm 1.8 – Nice short telephoto in low light but some CA (Chromatic Aberration).
EF Rokinon 85mm 1.4 Fast medium telephoto with EF mount for adapter. (Focus direction is the same as Pany's)
OM 135mm 2.8 – Great for low light at long distance.
OM Vivitar (Kiron) 55mm 2.8 Macro – Very sharp and close
OM Tamron SP 500mm F8 Mirror – I have had this lens for a long time and it gets me closer than any other but needs tons of light or high ISO.
The manual lenses work great with the GH2.
