The Olympus M.Zuiko 12-45mm f/4 Pro is light as an apple and can take macro shots – but is f/4 really "pro"?

Digital Camera World Verdict

The Olympus M.Zuiko 12-45mm f/4 Pro is an interesting proposition. It's a smaller and more affordable version of the 12-40mm f/2.8 Pro, sacrificing speed and functionality in favor of compactness and macro capability. If you shoot in good light or with flash, and especially if you enjoy macro photography, this is a fantastic all-purpose optic. However, since it's only moderately larger and more expensive, we can't think of many situations where we wouldn't opt for the faster 12-40mm lens instead.

The Olympus M.Zuiko 12-45mm f/4 Pro holds an impressive distinction: it is the world’s smallest and most lightweight fixed aperture standard zoom lens (in equivalent 35mm terms, this is a 24-90mm lens). 

To put that into perspective, its 254g weight is about the same as a large apple – and its compact 70mm length (and 63.4mm diameter) is actually smaller. So Olympus has achieved an incredible feat of a truly pocketable constant aperture standard zoom – and one that is even capable of macro photography.
