OLYMPUS M.Zuiko Digital ED 12-100MM f/4 IS Pro Lens
The Olympus 12-100mm F4 IS Pro is a rugged, professional-level zoom lens with a focal length range that can cover almost any everyday situation. It also focuses impressively close, only adding to its versatility.
Handling and design
The M.Zuiko 12-100mm F4 joins Olympus’ Pro lineup of prime and zoom lenses, offering top-notch build quality, with claims of dust-proof, splash-proof and freeze-proof construction. It has a manual focus clutch mechanism, giving the feel and very nearly the response of a mechanical focus ring, even though it’s technically a focus-by-wire system. The large, metal-ribbed zoom ring has just the right amount of resistance to it.
There’s no denying it, hold this lens in your hand and it just oozes quality. Nearly everything is metal, though even the plastic IS switch on the side of the lens doesn’t so much ‘snap’ into place as ‘thunk’.
What you get in exchange for this feeling of solidity, though, is some heft. At 561g (1.24 lb), it’s very nearly the weight of an Olympus E-M1 Mark III, and significantly weightier than the E-M5 Mark III and E-M10 Mark IV. That said, the larger grips of the E-M1 Mark III and E-M1X mean it actually balances quite well on those bodies.
Autofocus and stabilization
The Olympus 12-100mm F4 racks through the entirety of its focus range really quickly. It’s perhaps not quite as quick as some Panasonic lenses designed to take advantage of those cameras’ Depth-from-Defocus technology, but it’s more than fast enough for any wildlife I encountered, both inside and outside the Australia zoo.
The rapid AF speeds also make it easy to use the lens when you’re near minimum focus distance, allowing for easy capture of close-ups without necessarily needing to resort to manual focus.
