After 350D with EF 10-22 and 5D EF 17-40 L OM-D is now 9-18 with the third ultra-wide combi that I use. Clear, haptic something completely different than the 17-40, for small, light and with good image quality. As I said here umpteen times, this lens is the logical purchase for those where the DSLR is too heavy for holidays and always. Light intensity I in such focal lengths actually never missed, especially since the DSLR UWW lenses with high light intensity for optimum focus must be dimmed while the 9-18 at open aperture 4 already rather has its full sharpness, except for 18mm, where a stage dimming of 5 , 6 to 8 something brings.
The 7-14 I do not know, but would I have been too expensive.
The absence of the sun visor is of course annoying, but the 13 - Parts at Amazon outstanding meet their purpose ;-)
