Olympus 25mm f/1.2 overview

  • 1Description

A high-speed normal-length prime featuring an advanced optical design, the M.Zuiko Digital ED 25mm f/1.2 PRO Lens from Olympus is a 50mm equivalent lens designed for Micro Four Thirds mirrorless cameras. Its unique 19 elements, 14 groups construction incorporates extra-low dispersion, aspherical, and high refractive index elements to significantly reduce both chromatic and spherical aberrations for notable image clarity, sharpness, and color accuracy. The lens is also characterized by a bright f/1.2 maximum aperture, which benefits working in low-light conditions and affords extensive control over depth of field. 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.

Standard prime 25mm lens is designed for Micro Four Thirds mirrorless cameras and provides a 50mm equivalent focal length.
Exceptionally 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 intricate optical design employs one Super Extra-Low Dispersion element, two extra-low dispersion elements, one Extra High Refractive Index element, three 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.
A 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 25mm f/1.2 reviews

M.Zuiko Digital ED 25mm f/1.2 PRO Lens is rated 5.0 out of 5 by 17.
Rated 5 out of 5 by from Excellent Lens This lens is excellent. There's no way to exaggerate this. I thought that the lens would show some limitations due to the high number of elements, and I was surprised to see how accurate the lens is. It is scientific in its capture. In fact, it's too perfect if you're looking for something to soften your images. Even what you can't see with your eyes, you will see in your file, so you've got to be careful with your camera settings, speaking from a JPEG perspective. It's also beautifully made; aesthetically similar to the other pro lenses. I'm looking forward to more f/1.2 primes from Olympus.

Rated 5 out of 5 by from Seriously Awesome After a couple weeks with this lens I'm simply blown away. The detail, clarity, and rendering is outstanding. Some people don't think it's worth getting this lens when you already have the 25 f1.8, but I think they're wrong! I never really clicked with my 25 f1.8, but this lens is special. I could use it at f/1.2 all day and have no regrets. It's that good! If you value weather sealing, superior quality, and real manual focus, then the cost of this lens is easy to justify. I don't regret this purchase, and I really hope Olympus has plans to make more of these pro prime lenses.

Rated 5 out of 5 by from Excellent! I bought the Olympus 25mm 1.2 from B&H because I was waiting for a 50mm equivalent microfourthirds lens that was fast and with good bokeh. Microfourthirds cameras aren't known for bokeh. I have an Olympus Pen F because it focuses fast which is why I got a microfourthirds camera in the first place. When the 25mm 1.2 sample images were available online, they looked great. I bought one of the first lenses B&H had in stock. They shipped it fast without problems like usual. The lens is fast and the bokeh is amazing. The build quality is excellent. It exceeds my expectations. In poor lighting, wide open at f/1.2, focus is still very fast! I rarely miss shots. I can't think of too many 50mm lenses that are better wide open for fast focusing street photography. I highly recommend it for Olympus microfourthirds cameras.

Rated 5 out of 5 by from A landmark lens in Olympus' m4/3 lineup This lens is going to be regarded as a landmark lens in the evolution of the m4/3 system. Not only is it optically excellent with beautiful rendering of out-of-focus areas, little CA or distortion, and great DOF control, but it also achieves very fast and accurate AF, making this lens much more accessible and practical than brighter alternatives that require manual focusing.

Rated 5 out of 5 by from Excellent Lens I didn't purchase this lens directly from B&H but rather a friend who had purchased it here. Since I got the lens it has hardly left the camera body (Olympus E-M-5 Mark II). The construction is incredibly solid, carry a little weight, but not enough to be cumbersome. At F1.2 this camera produces beautiful bokeh and shallow depth of field and can still produce a beautiful clear image. I like to shoot in darker and low-light settings, and this lens is perfect for that. The AF is fast and having the manual clutch is great. This lens is well worth the price tag.

Rated 5 out of 5 by from Sharp lens! I must've been one of the first few to get this lens from B&H. I bought it to use on my Pen F. This lens is just awesome and crazy sharp even at f1.2. It also has pleasing bokeh which makes it great for portraits. Built like a tank. Way to go Olympus!

Rated 5 out of 5 by from Fantastic I rarely write reviews, but I just needed to say out loud that this is one of those lenses that you purchase from time to time that easily eclipses the performance of the body to which it's attached. �It's been a great purchase for me, and although I was on the fence with spending the money, I'm now easily able to say that I would spend the money again. The lens is just that good.

Rated 5 out of 5 by from All around great lens! This lens is meant to never leave a camera body. Excellent construction as with all Pro lens from Olympus. Great image quality even wide open. There are people complaining about weight and size. I do not see any issues with it because it feels just right on camera and is balanced very well.
