I have no experience with it. Attaching a wide conversion lens to a specified normal lens can make the lens wider. I want to know the effect on IQ: sharpness, distortion, vignetting, flare, focussing, etc. I also want to know if the wide conversion lens changes the aperture of the lens. Does any body have experince with a wide conversion lens?
A specific example that draws my attension is the new pana DMW-GWC1. According to the descrption, it can be attached to a pana 14mm f2.5 to make it an 11mm lens (not mentioning the aperture). If the IQ is not reduced much, then it sounds a good deal to have a detached 14/2.5 (low price) + a DMW-GWC1. Then you will get two (U)WA lenses: an equiv. 28mm/f5 + an equiv. 22mm/f5(?). What do you think?
Thanks,
Frank
