Olympus 150-400mm f/4.5 IS Pro Field Test


Initially unveiled alongside the E-M1X back at CP+ in 2019 as a development announcement, the M.Zuiko 150-400mm f/4.5 TC1.25x IS PRO lens is arguably Olympus' most ambitious new lens, offering a massive amount of telephoto reach yet sporting their characteristic portability and lightweight design as a central feature. Almost two years later, the Olympus 150-400mm f/4.5 lens is finally here, and it is one stellar piece of optical equipment.

Aimed squarely at professional and serious enthusiast nature and wildlife photographers, this new Zuiko Pro-series lens offers impressive telephoto versatility with a base 300-800mm-equivalent zoom range. However, the lens also comes equipped with a built-in 1.25x teleconverter, and at the flick of a switch you can reach out to a 1000mm-eq. focal length. But wait, there's more! The lens is also compatible with Olympus' standalone teleconverters, and when you add on the MC-20 2x TC, you have a 2000mm-equivalent supertelephoto lens that you can easily use hand-held (despite appearances) thanks to its unique lightweight construction and powerful image stabilization.


Olympus already wowed us and many others in the wildlife world with the 300mm f/4 IS Pro lens, but the new 150-400mm f/4.5 IS Pro lens takes things to an all-new level. Designed to compete against larger, heavier and more expensive super-telephoto zoom lenses, such as the Canon 200-400mm f/4L IS or the Nikon 180-400mm f/4E VR, the Olympus 150-400mm offers a surprisingly lightweight, portable and fully weather-sealed package as well as impressive image quality performance and AF speeds.


However, all this exciting technology, features and unique design doesn't come cheap. With an MSRP of US$7,499, the 150-400mm f/4.5 TC1.25x IS PRO is without a doubt a serious investment, and by far Olympus' most expensive lens offered in recent years. However, when you consider the full-frame competing lenses often range past the $10,000 mark, things become a bit more interesting.
