The biggest story in the camera world over the past six or seven years—aside from the impending extinction of point-and-shoots—has been the meteoric rise of mirrorless cameras. Micro Four Thirds in particular has really blossomed over the past several years, filling out with high-end, high-performing bodies like the Panasonic GH4 and Olympus OM-D E-M1.

But great cameras are nothing without great lenses to back them up. Micro Four Thirds is known for quality, compact optics, but the early wave of lenses definitely left room for improvement on the top end. With the Panasonic-developed, Leica-approved DG Nocticron 42.5mm f/1.2 (MSRP $1,599.99), that improvement has arrived in a big way. A supremely well-built lens with excellent sharpness and killer bokeh, it can rival the best portrait glass from leading full-frame systems.

Yes, it’s very expensive, but if you want the best portrait lens that Micro Four Thirds has to offer—heck, the best lens period—this is it.

Who's It For?

For Micro Four Thirds shooters, the Pana-Leica Nocticron 42.5mm f/1.2 is the premier choice for portrait photographers, and a great choice for street photographers as well. Its f/1.2 maximum aperture is the widest you can get in an autofocus M43 lens, making it ideal for low-light shooting and shallow depth of field applications.

In particular, that light-gathering ability is a real help on Micro Four Thirds cameras, where high-ISO image quality (though much better than it was a few years ago) still lags behind many APS-C and full-frame cameras.

On Micro Four Thirds cameras, this 42.5mm lens behaves like an 85mm lens would on a full-frame camera.

The main limiting factor here is, of course, price. At $1,600, the Nocticron is going to be an aspirational purchase for all except professional photographers and the most well-heeled enthusiasts. And the premium is especially glaring given the existence of far more affordable, high-performing alternatives like the Olympus 45mm f/1.8 ($400) and Pana-Leica 45mm f/2.8 Macro ($900).

Look and Feel

As soon as you pick up the Nocticron 42.5mm f/1.2, it becomes clear that you’re dealing with a whole new class of Micro Four Thirds lens. It's built to be (almost) on par with your typical Leica lens, with a tight, all-metal design that includes a generously sized focus ring and a dedicated aperture ring. Both rings offer reassuring action; the focus ring is exquisitely smooth, and the aperture ring clicks confidently into place.

The manual aperture ring feels great, but it's not mechanically linked; it simply tells the camera what to do in M and Av modes.

That control combo makes the Nocticron an excellent choice for hardcore enthusiasts who prefer an old-school, hands-on approach to photography. However, it's worth noting that the aperture ring presents a bit of a fragmentation problem, since it's only supported by Panasonic cameras; if you're shooting with the Nocticron on an OM-D, it's totally useless.

The Nocticron has manual switches to control both focusing mode and optical image stabilization.

The aperture ring isn't mechanically coupled to the actual iris, either, so it’s really just a fancy way of telling the camera which setting to use in the manual and aperture priority modes. When you’re in program or full auto the camera will usually ignore whatever the lens is set to and follow its own programming.

From a handling perspective, the only downside is that the Nocticron is quite large compared to most Micro Four Thirds primes, an issue exacerbated by the almost comically large lens hood. The hood helps reduce flare, but it also makes the lens considerably less discreet.

Image Quality

When the Nocticron arrived in our labs for testing, we were already very well-versed in its capabilities. Having shot with it several times over the past 18 months, we knew to expect sharp results, virtually nonexistent aberrations, and well-corrected distortion.

What we didn't expect was a lens that would destroy the rest of the Micro Four Thirds pack. In the lab, mounted on a GH4, the Nocticron achieved peak sharpness figures well above what we've seen from other lenses in the system. (The Olympus 75mm f/1.8 is the only rival that even comes close.) It's already very sharp in the center at f/1.2, and the resolution figures become truly exemplary from f/2.8 through f/5.6.

Creatively, we've simply fallen in love with this lens. It produces some of the best bokeh around, and certainly some of the most beautiful shots that we've ever gotten from a Micro Four Thirds lens. The innovative lens design even reduces the nasty "onion ring" effect that tends to plague other lenses with aspherical elements, rendering out-of-focus points of light exceptionally well.

All in all, this is easily our favorite Micro Four Thirds lens. If you're committed to the system and shoot lots of portraits, this is hands-down the lens that you should get, provided it's within your means.

Conclusion

If you own a high-end Micro Four Thirds camera, you're probably the kind of photographer that the Nocticron 42.5mm f/1.2 was created for. You know, an enthusiast who's not above spending some serious coin to get the most out of your gear. This is a lens that can most definitely achieve that objective.

In the words of Ferris Bueller, "It is so choice." It’s endless fun to shoot with, and the results are almost effortlessly sharp, contrasty, and beautifully rendered. Perhaps most importantly, the bokeh is wonderful, smooth, and consistent from f/1.2 onward.

The Panasonic Lumix G Leica DG Nocticron 42.5mm f/1.2 is a fairly big lens, but isn't overwhelming.

A word of caution, though: don’t fall in love unless you can part with some serious cash. This is, without question, my favorite Micro Four Thirds lens and it may quickly become yours, too. That’s a dangerous game to play, especially if you're not good at resisting four-figure impulse purchases. It goes on sale often, but even at $1,300 or $1,400 it’s a tall order.

Panasonic has clearly heard those concerns, and a new Nocticron is on the way, packing the same 42.5mm focal length but a more pedestrian f/1.7 aperture. It may not achieve quite the same staggering results as the f/1.2 version, but it’s set to arrive at a far more reasonable $400 MSRP.

But let's be real: The Nocticron 42.5mm f/1.2 is a halo product, a flare that Panasonic and its partner Leica have sent up to show the world what they can do. It's something to scribble on the “someday” list, or pick up if you get an unexpected windfall. And while it's incredibly good, we can't say that it quite justifies its astronomical price tag—especially given the bargains to be found elsewhere in the Micro Four Thirds family.

But whether you're seriously considering picking one up, or simply drooling over the possibility, this is a lens to keep your eye on. It won't wind up in everyone's bag, but it sets a new standard against which all Micro Four Thirds lenses should be compared.
