Olympus M.Zuiko ED 45mm f1.2 PRO Review - Review 2022

Olympus wasn't first to release an ultra-wide aperture portrait lens for the Micro Four Thirds system. Panasonic brought the 42.5mm Nocticron f/i.2 to marketplace four years agone. Nosotros were wowed by the 42.5mm and gave it an Editors' Option award, in part because of how unique an offering information technology was. Now information technology has a competitor, in the form of the Olympus Yard.Zuiko ED 45mm f1.2 PRO ($1,199). The Olympus is less expensive, but as impressive from an optical standpoint, and built extremely well. That makes information technology our new Editors' Pick.

Design

Like the other lenses in Olympus' f1.ii PRO series—the 17mm f1.two and 25mm f1.2—the 45mm f1.2 ($1,149.00 at Amazon) is housed in a black metal butt. It'due south well-nigh the same size and weight equally its siblings, 3.3 by 2.8 inches (HW) and 14.five ounces. Information technology also uses the aforementioned filter size, 62mm, and so you can use i set of filters for the entire serial.

A reversible lens hood is included, as is a soft carrying pouch. The lens is sealed both internally and at the mountain to protect information technology from dust and wet. I shot with it in heavy snowfall, paired with the sealed Eastward-M1 Marking Two, and it held upward like a champ. I do recommend pairing the lens with a trunk with a large handgrip, like the E-M1, equally it's a bit heavy to use with smaller, slimmer bodies.

There'south a unmarried control button on the barrel, L-Fn, that can be set to perform different functions via your camera'due south menu. There's no integrated image stabilization, only both Olympus and Panasonic build that characteristic into Micro Four Thirds camera bodies.

Fans of transmission focus volition capeesh the focus clutch system. Pulling the knurled metal focus band toward y'all switches the lens to manual focus. Dissimilar most mirrorless camera lenses, which don't offer whatever sort of difficult stops or tactile feedback when focusing manually, the 45mm offers some amount of physical resistance when turning the ring and includes a distance scale and difficult stops at both ends of its focus range. Focus is all the same adapted using the motor, but the lens feels like a mechanical model. That'south peculiarly important for a portrait lens with such a wide discontinuity, as the design means you lot can make very precise adjustments to focus then yous can lock in on your subject's eyes.

The lens focuses to 19.vii inches (0.5-meter), at which it captures subjects at 1:10 life-size. Information technology'south certainly non a macro lens, but you can still frame very tight headshots when shooting portraits. The Panasonic Nocticron doesn't offer an advantage or disadvantage when information technology comes to shut focus—its minimum focus adequacy matches the Olympus.

Image Quality

I tested the 45mm f1.2 with the 20MP E-M1 Marking Two ($i,199.00 at Amazon) . At f/1.2 it puts up very strong resolution numbers, 2,581 lines using Imatest's center-weighted sharpness test. Epitome quality is very strong from the center to the edge of the frame; even the farthermost periphery shows 2,300 lines. Those are excellent results for a 20MP sensor; nosotros consider 1,800 lines to be the minimum acceptable upshot.

Encounter How We Test Digital Cameras

We see a very modest bump in resolution as the aperture narrows—2,635 lines at f/1.4, 2,743 lines at f/2, 2,854 lines at f/two.8, 2,818 lines at f/four, two,797 lines at f/v.6, and two,830 lines at f/8. At the narrowest f-stops there'south a drop in resolution due to diffraction—we meet two,541 lines at f/11 and merely 2,057 lines at f/sixteen.

Olympus has described the bokeh captured by the lens (the out of focus expanse behind or in front end of your discipline) every bit feathered. In that location are a number of factors that contribute to only how the bokeh looks, including the background itself, focus altitude, f-stop, and distance between the subject and groundwork. And so I tend to take any marketing claims about how the blur looks with a grain of salt. Consider the to a higher place sequence, showing how the lens draws a particular scene, as just ane example. In general, I found the 45mm to draw backgrounds pleasingly.

The lens doesn't bear witness any visible distortion, a plus for one with such a wide aperture. There is some dimness at corners when shooting wide open. We run into a -1.2EV driblet at f/1.ii and a -1.1EV deficit at f/one.iv when comparing the corners of an paradigm with the center.

Conclusions

The Olympus M.Zuiko ED 45mm f1.2 PRO is an excellent performer. It combines a short telephoto bending of view, ideal for portraiture, with broad aperture optics, a weather-sealed build, and a pleasing transmission focus experience. And it does it all for $400 less than its closest competition, the Panasonic Nocticron 42.5mm f/1.ii ($i,197.99 at Amazon) . All of this comes together to make the Olympus our Editors' Choice. It'southward not the only portrait lens available for Micro 4 Thirds cameras, of course. If you're on a tighter upkeep, consider instead the Olympus Yard.Zuiko Digital ED 45mm f1.8, which doesn't assemble as much calorie-free or snap images with quite as much background blur, only is priced at simply $400.
