Best Zoom Lenses for Micro Four Thirds

October 21, 2021

Zoom lenses are ideal when you want to use a variety of focal lengths without the hassle of changing lenses. Here we look at some of the best zoom lenses available for the Micro Four Thirds mount, used by Panasonic and Olympus.

Don’t forget that you can use lenses from either brand on your Micro Four Thirds camera. So, if you’ve got an Olympus, you can use a Panasonic lens, and vice versa.

The crop factor associated with Four Thirds sensor is 2x. That makes it nice and easy when calculating the “equivalent” focal length, as you just double whatever it says. So, for example, a 12-35mm lens becomes a 24-70mm lens.

For this piece, we have separated the zoom lens options into standard, all-in-one (or superzoom), and telephoto zoom lenses.

Standard zooms and all-in-one lenses are great options as “everyday” or “walkaround” choices, giving you a good degree of flexibility for a range of different situations, such as landscape, travel and even portraiture. Telephoto zoom lenses on the other hand are more suited to specific types of photography, such as wildlife, sports or action – basically anything which requires you to get closer to the action.

Best standard zooms for Micro Four Thirds

Panasonic 12-35mm f/2.8 II LUMIX G Vario ASPH Power OIS Lens

Equivalent focal length: 24-70mm | Street Price: £879

Panasonic Lumix 12-35mm f2.8

This standard zoom lens is equivalent to the classic focal length of 24-70mm which is favoured by many full-frame shooters. It’s also got a nice wide constant f/2.8 aperture. It’s suited well to larger cameras such as the Panasonic GH5, and makes for an excellent walk around lens. At its widest, it’s ideal for landscapes and travel, while the tele end is great for portraiture and street work. You can use it in low light conditions, using the widest aperture of f/2.8. It’s also great for throwing the background out of focus for shallow depth of field effects. Support is available for the Power OIS (optical image stabilisation) as well as in-camera 5-axis Dual IS 2 when used with certain cameras such as the GH5 / GH5 II and G80.

Panasonic LEICA 12-60mm f/2.8-4.0 DG VARIO-ELMARIT POWER OIS Lens

Equivalent focal length: 24-120mm | Street Price: £879

Leica DG Vario-Elmarit 12-60mm f/2.8-4.0

Panasonic has a great working relationship with Leica, which it has teamed up with to create this standard zoom lens. Offering more reach than the 12-35mm lens, as a trade off, you have to settle for f/4.0 at the telephoto end of the lens. Again, due to its reasonably large size, it’s best used with larger cameras, or those that take the DSLR form, such as the GH5. This lens is also splash proof and dustproof, making it ideal for all kinds of outdoor work.

Olympus 12-40mm f/2.8 M.ZUIKO PRO Lens

Equivalent focal length: 24-80mm | Street Price: £799

OM-D E-M1 12-40

A classic walk around length for Olympus users, this lens gives a touch extra reach than the Panasonic 12-35mm equivalent, while offering the same f/2.8 constant aperture. A great choice for cameras such as the OM-D E-M1 Mark III, it’s a versatile option for lots of different subjects ranging from landscapes to portraits. It is also weatherproof which makes it ideal for outdoor work.

Olympus M.Zuiko Digital ED 12-200mm f/3.5-6.3

Olympus 12-200mm review

The Olympus M.Zuiko Digital ED 12-200mm f/3.5-6.3 all-in-one “super zoom” lens offers a somewhat incredible 24-400mm equivalent zoom range. The lens benefits from a weather-resistant construction, but due to the lack of optical image stabilisation, it’s not recommended for use on cameras that don’t feature in-body image stabilisation (IBIS), as it could be tricky to get sharp shots when using more of the telephoto zoom. It’s also not as sharp as other lenses, particularly at the telephoto end of the lens, however, this is often the case with super zoom lenses.

Panasonic 35-100mm f/2.8 II LUMIX G X VARIO POWER OIS Lens

A classic focal length enjoyed by traditional full-frame photographers, the equivalent focal length of this lens is 70-200mm. The maximum wide aperture of f/2.8 is constant, making it ideal for lots of subjects, including portraiture, as well as being great in low light.

For those who spend a lot of time outdoors, the splash, dust and freeze proof construction of the lens will surely be appreciated. Focusing is also near silent, and if the 300mm (equivalent) isn’t enough, you can purchase an extra 1.4x teleconverter to extend it to an equivalent of 420mm. If your budget doesn’t quite stretch to the high asking price of this lens, there’s also a 40-150mm f/4-5.6 offering available.

It’s also splash proof and dustproof, making it ideal for subjects such as wildlife and outdoor photography.
