The E-620 seems to have more noise in the images than the E-420 which is another reason I prefer the images from the E-420. I've used the Vario-Elmarit 14-150 f3.5-5.6 on the E-420 a lot and since the lens had ILIS it worked out great. That lens is sharp at all apertures at all focal lenths. It also still retails for some €1100. Quite an asking price but well worth it in my mind.
