Olympus M.Zuiko Digital ED 45mm f/1.2 PRO Overview

An ideal portrait-length lens for Micro Four Thirds shooters, the M.Zuiko Digital ED 45mm f/1.2 PRO from Olympus pairs the desirable 90mm-equivalent focal length with an ultra fast f/1.2 maximum aperture. The combination of the slightly narrow field of view and bright aperture enable producing distinct shallow depth of field imagery, and also suit working in difficult lighting conditions. This lens is also characterized by its advanced 14 elements in 10 groups optical design, which incorporates low dispersion, aspherical, and high refractive index glass elements to control a variety of aberrations and distortion for great sharpness, clarity, and color fidelity. A nine-blade aperture is featured as well, to achieve a smooth bokeh quality when working with shallow depth of field techniques, and a Z Coating Nano has been applied to individual elements to limit flare and ghosting for improved contrast.

Beyond the imaging assets, the lens' physical design is characterized by a weather-sealed construction to benefit working in harsh climates. It also features a Movie & Still Compatible (MSC) autofocus system for smooth, quiet, and fast focusing performance that is suitable to both stills and video recording. A manual focus clutch permits quick switching to MF control and a printed depth of field scale is also featured on the lens barrel for pre-focusing and hyper focal focusing techniques.

Portrait-length 45mm lens is designed for Micro Four Thirds mirrorless cameras and provides a 90mm equivalent focal length.
Notably fast f/1.2 maximum aperture supports working in difficult lighting conditions and affords extensive control over depth of field for selective focus techniques.
The complex optical design incorporates one extra-low dispersion element, four high refractive index elements, and one aspherical element, which all work in concert to control chromatic and spherical aberrations for improved clarity, reduced color fringing, and enhanced sharpness.
A Z Coating Nano has been applied to individual lens elements to noticeably reduce surface reflections and prevent lens flare and ghosting for improved contrast and color neutrality in strong lighting conditions.
An MSC autofocus system, along with an internal focusing design, provides quick, quiet, and precise focusing performance to benefit both still photo shooting and movie recording. Additionally, an MF clutch is used for fast changing to manual focus for more precise control.
Programmable L-Fn (lens function) button for easily accessible settings adjustment.
Weather-sealed construction guards the lens against dust, moisture, and freezing temperatures for working in harsh environments.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

Olympus M.Zuiko Digital ED 45mm f/1.2 PRO Reviews

Almost too sharp

By Anne
Rated 5 out of 5
Date: 2021-12-14

I'm converting over from full frame N and used to shoot headshots with their 105 macro and it was a great lens for that purpose. I bought the Olympus 45 1.2 Pro for several dozen headshot for a client and was so amazed by the sharpness on every single image. Using the eye detect auto-focus nailed it on every shot. I actually had one person ask me to soften her images because they were too sharp for her liking. It's the right size for me on the E-M1.3 with the battery grip. I'm looking forward to more portrait sessions with this lens.

This lens is wonderful for my OMD 1M Mark iii. It is super sharp even at f1.2 and gives a nice creamy backround. Super fast focusing. I have only had it for a short time but plan on using it for some portraits and general street shooting.

A Leading Portrait Lens, Period

By Baron
Rated 5 out of 5
Date: 2021-03-04

This lens is easily one of the best for portraiture in any system—not just a good MFT portrait lens, it is a truly great portrait lens, period. It holds its own against the best lenses from Canon, Nikon, et al and in some ways, outshines some of them. It's certainly far smaller, lighter, and cheaper. It renders lovely colors and is extremely sharp and contrasty, and has an absolutely gorgeous blur in out-of-focus areas, both background and foreground. Additionally, the transition from the in-focus to out-of-focus areas is exceptionally smooth and attractive. The secret to how they achieve this is what they call feathered bokeh, meaning the bokeh balls aren't crisp-edged, but have a gradient from center to edge. As a result, out-of-focus areas just melt together into a lovely cotton-candy delight. It is better at this than almost any lens in almost any system; the only thing that rivals it, in my opinion, is apodization lenses like Fuji's 56/1.2 APD, which achieves that effect at the cost of losing a lot of brightness. (Other lens makers have similar technology but call it different things. To be clear, I'm not saying this lens is the absolute best in the world, I'm just saying it's hard to find anything better.) Olympus's feathered bokeh is achieved by very strategic undercorrection of spherical aberration, and works brilliantly. It does not, however, come at the cost of lowered quality in other aspects, such as sharpness or contrast. And if there's any color fringing, distortion, coma, etc—I have yet to see it. For my purposes, this is basically a flawless lens. And did I mention that it's half the size, weight, and cost of top portrait lenses like 85mm f/1.4 or f/1.2 from Canon, Nikon, Sony, Zeiss, et al? Actually, compared to Zeiss, it's much less than half. I'm attaching some SOOC JPG bokeh-ball shots, both front- and back-focused (see if you can tell the difference! hard, isn't it?) and a quick snapshot of my dog who happened to be lying there—and the dog shot has sunlight striking the front of the lens nearly head-on, look how little flaring and contrast veiling there is. Truly remarkable. Also, I've used both, and it's FAR better than the 42.5mm Panasonic lens, if you're trying to choose between the two.

Beautiful lens for the OMD EM1 MKII

By James

Date: 2020-12-24

I bought the Olympus 45mm F 1.8 and while it works well, i found it to be small to use in event photography on my Olympus EM1 MKII, so I will use that to shoot the grand kids, I ended up buying the Oly 45mm F 1.2 Pro, while it is a lens that coast just over 11 hundred dollars, it gives me a cheaper option than the Pentax 85mm F 1.4 with less weight. this lens on the Olympus OMD EM1 MKII is pure magic, the two were meant to be together and is a great combo for head shots and people photography.

Pro Glass as Advertised

By Jeff
Rated 5 out of 5
Date: 2020-06-11

The Olympus 45mm f/1.2 Pro lens is not for the faint of heart. By micro four-thirds standards it is a large, heavy, expensive, chunk of glass. By full-frame standards, it's really not too large, but... The lens is bright and fast-focusing. Weather sealing adds to its feature set. In use, the lens is sharp from wide open, but the photographer must be very careful about focus because the depth of focus is really small! Out of focus areas fade away in the creamiest bokeh that one can imagine. The lens can focus close enough that it almost can substitute for a macro lens - if not too close. Worth the money? That's a personal evaluation, but I want to get out more and USE it.

Makes me look like a pro.

Awesome lens for portrait work

I don't know why I waited so long to buy this lens. Very sharp at f 1.2 and love the bokeh I get on my shots. I would recommend this lens to anyone who is serious about portrait work.

Wish I purchased it sooner!

I've been thinking about purchasing this lens for some time. I finally decided to pull the trigger when a friend of mine asked me to photograph his small wedding. I now wish I had bought it sooner! Its true what they say - it really is tack sharp even when wide open. The bokeh is amazing - and for me personally it was the right choice between the 25 pro, 45 pro and the 75. For my needs (some portrait, landscape and street) - its perfect. I'm very happy with this purchase and of course B&H got it to me in time for the wedding! Yes it is expensive, but totally worth it.

No matter what auto focus lens one uses on the camera body, if the camera supports "focus stacking", it will focus and work with the camera in the focus stacking mode.

Both are excellent lenses, just a matter of different focal lengths. For portraits with very shallow depth of field, the 75mm is a great choice.

This lens doesn’t appear to have image stabilization. Is that an issue shooting on a body that doesn’t have IBIS (such as a GH-4)?
Asked by: Titus
Just like in the days prior to IS, a steady hand and appropriate shutter speed are required for sharp images.
