From memory there isn't much difference and the 45-75 is light but does not feel cheap. The 14-42 does not stick out so much as the 20mm when turned off but it does protrude when turned on. THE most important thing is IQ and i think these lenses deliver!Thanks Andy! How does the size of the 45-175 stack up against the Oly 40-150?
The little 14-42 may be a good fit for the Pens too! If mounted on a Lite or Mini, would the lens protrude beyond the lens mount like the 20mm does on the Lite and Mini? Thanks for the info!
