Cheap UWA Option for Micro Four Thirds Cameras
This is a solution for those who want to take wide angle photos and videos without spending a thousand dollars on an expensive Olympus or Panasonic lens. The lens is the Panasonic 12-32mm f3.5-5.6 with the Ricoh DW-6 wide angle converter attached. This gives you a focal length of 9.5mm (12mm x 0.79).
The image above shows the combination at 9.5mm (f9). The inset image is the 12-32mm at 12mm (f3.5). With the converter attached to the lens it is best to stop the aperture down a little, although f9 was probably too much- f5.6 or f8 would have been better. As you can see the field of view is significantly wider compared to the lens alone at 12mm.
This combo cost me under £140 new, including a 37mm to 43mm step-up ring. However, I probably got lucky with the wide angle adapter with it being sold for around £30 on eBay and marked as new. The Panasonic 12-32mm was new and separated from a kit on eBay. Step up rings are something like £2.49.
