The one area where this lens does fall short, however, is in control over depth of field, and this is a direct consequence of its miniaturization. For any given angle of view, the small size of the Four Thirds sensor requires a shorter focal length lens when compared to other DSLR formats, and at any given f-number, this results in a smaller aperture diameter, and consequently increased depth of field. Generally Olympus have compensated for this effect in their other lenses by offering larger maximum apertures, but with the 14-42mm they have chosen to use the same f-number range, in order to reduce size. This in turn reduces the lens’s flexibility when the user wishes to isolate the subject from the background using a large aperture, one of the key image controls of creative photography. So not surprisingly, there is a price to pay for the increased portability of this small lens.
That aside, this really is one of the best standard zooms currently available, and the ideal complement to Olympus’s compact DSLRs such as the E420, where the trade-off between portability and flexibility makes most sense.
