If i were to get this adaptor which wide angle zoom lens would be best that is no more expensive than the olympus 9-18mm micro four thirds lens, i use long lenses mostly but will need a wider zoom than the kit lens as well Compatibilities of DMC-GH2 | Compatibility | Digital Camera | Product Support | Support | Panasonic Global (http://panasonic.jp/support/global/cs/dsc/connect/gh2.html) shows the available lenses i can not find a panasonic fit sigma 10-20mm in the uk.

This adapter allows all four thirds to fit micro, but you are still very limited to find fast wide angle zooms - ie. F2.8. Most are F.4

You can get the Sigma 10-20 at B&H and this is a good lens.

Sigma 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Four 201107

Is that lens rated better than the olymous 9-18mm micro lens, thanks for the reply
