Leica DG Nocticron 42.5mm f/1.2 ASPH. POWER O.I.S. Lens with UV Filter Overview

More than just the lens, the Panasonic Leica DG Nocticron 42.5mm f/1.2 ASPH. POWER O.I.S. Lens with Lens Care Kit from B&H bundles the portrait-length prime with 67mm UV Filter.

Panasonic Leica DG Nocticron 42.5mm f/1.2 ASPH. POWER O.I.S. Lens

Characterized by its fast and sophisticated optical design, the Leica DG Nocticron 42.5mm f/1.2 ASPH. POWER O.I.S. from Panasonic is an 85mm equivalent prime for Micro Four Thirds mirrorless cameras. The fast f/1.2 maximum aperture benefits working in difficult lighting conditions and also affords more control over focus position for producing shallow depth of field imagery. The lens's optical design employs a pair of aspherical elements, one UHR element, and one extra-low dispersion element to reduce both spherical and chromatic aberrations for improved sharpness and clarity. Additionally, a Nano Surface Coating also enhances contrast and color fidelity by reducing lens flare and ghosting.

Complementing the optical attributes, this lens also distinguishes itself with a POWER Optical Image Stabilizer, which minimizes the appearance of camera shake for sharper handheld shooting. A stepping AF motor and internal focus design also offer fast and near-silent focusing performance that is ideal for both photo and video applications.

Portrait-length prime is designed for Micro Four Thirds mirrorless cameras and provides an 85mm equivalent focal length.
Exceptionally fast f/1.2 maximum aperture offers notable control over depth of field for working with selective focus techniques and also benefits shooting in low-light conditions.
Two aspherical elements and one Ultra-High Refractive Index element help reduce spherical aberrations and distortion for improved sharpness and accurate rendering.
One extra-low dispersion element controls chromatic aberrations and color fringing for greater clarity and color accuracy.
A Nano Surface Coating minimizes surface reflections throughout the entire visible spectrum for maintained contrast and color fidelity with a marked reduction in lens flare and ghosting.
An internal focusing system, coupled with a stepping AF motor, results in fast, smooth, and precise focusing performance that is well-paired to both still shooting and movie recording.
POWER Optical Image Stabilizer (O.I.S.) minimizes the appearance of camera shake to realize sharper imagery when shooting handheld.
Metal lens barrel is accentuated by a dedicated MF/AF switch and an aperture ring for more direct, intuitive operation.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

Chiaro Pro 67mm 98-UVATS UV Filter

The Pro 67mm 98-UVATS UV Filter is one of Chiaro’s highest-rated protective UV filters with 98% light transmission. It’s ideal for photographers of all levels who demand high-quality glass and other essential features for excellent image fidelity and construction.

To achieve 98% light transmission, Chiaro uses highly-polished optical glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. A scratch-resistant coating minimizes scratching of the glass and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. Its hard-anodized aluminum filter ring is designed to screw on and off effortlessly, and it is thin to prevent vignetting when used with wide-angle lenses. Side knurling helps assure that you’ll have a firm grip when attaching or removing your filter.

Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.

98% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished optical glass and advanced coatings, Chiaro offers a 98% transmission rate, which is an excellent transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.
Resistance Coating
The layers of advanced resistance coating on the filter are designed to resist moderate scratches, and allow you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.
Polished Optical Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is highly-polished for flatness that ensures excellent optical clarity.
Multi-coating enhances light transmission to the demanding level set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.
UV Protection
The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
Hard Anodized Aluminum Construction
The process of hard anodizing toughens and strengthens the aluminum for a lightweight yet durable filter ring.
Slim Design
Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
Top and Side Knurling
In addition to top knurling, Chiaro added side knurling to better grip the filter when you're attaching and removing it, or when you're stacking filters.
Secure Attachment
It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.
Front Threads
The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.

Hands down the best MFT portrait lens

By Daniel
Rated 5 out of 5
Date: 2022-12-13

Buy it. Get yours before they stop making them. If you want the best, then this is it. Just phenomenal. For portraits, there is nothing better on micro four thirds. This lens on any Panasonic micro four thirds is the reason for going MFT. (I shoot/own Nikon D3/D3x/D4s/D810 - so yeah I love my 200f/2.0 on the D3x, but this is comparable and it's $15k less (sure used now $4k) and one tenth the size and weight.) Have a good one.

Love this lens.

The Nikon 85mm was my favorite lens for my film camera. Now I enjoy this one. It does add some weight.

It's the best. If you can afford it, get it.

I'd like to address this to people like me who started out poor and are in better circumstances. I know all about compromising. I did it constantly for years. The law of diminishing returns is a real and inescapable thing. But after having exposed maybe four images with this lens I can tell you it's astonishingly good and if you're a professional or committed amateur who can afford it just for God's sake get it. There are pretty good alternatives-from Panny and Olympus both, and I'm sure others-but this is quite simply the best lens I've ever used and I've used scores of them. Wide-open sharpness, bokeh, contrast, it's all there. If you need or want the best portrait-length lens for the system, just for Christ's sake buy it. You won't regret it.

Amazing lens, until Leica got involved.

Tack sharp, creamy bokeh, beautiful color renditions (worth 5+ stars). However the frustration is the 'a la' Leica metal hood, and non locking [A] f/stop position that will easily move when using the lens. The hood should have been a quality resilient plastic, with a twist bayonet reversible mount. Further insult, is the plastic ring in the shade with a bad glue that will ooze when exposed to natural heat/warmth! The lock knob is just AWFUL.

This is the best of the dozen + MFT lenses I own.

Everything about this lens makes it an investment worth making. It has the fastest focus, best color, most clarity, and it's incredibly sharp even at 1.2. Solid construction and will last for decades. It really is a dream to work with. For me, the 30mm Sigma DN takes second place as far as prime lenses go. It's a better value for the $$, but use this lens in the field and you will know why it's 4x the price. It's truly a pleasure to operate.

Love the clarity of this lens

I primarily use my M4/3 camera for vacation trips but this lens may force me to use it more for portraits. The focus is quick and precise with fantastic bokeh. I am used to using a full frame camera for my portraits but decided to see how this lens did with one of my poses. It is sharp and made the weeds behind them blend into a beautiful background. I highly recommend this lens.

An Amazing Lens!

This lens is all it was supposed to be. I am able to shoot handheld shots at F 1.2 in low light and get sharp results.

For some reason my BMPCC4K stopped to recognize the image stabilization and the F/1.2 (it reaches to F/1.3). Is this a common problem with the lens ? If yes is there any known fix about it ? If not, what would you suggest of me doing in order to solve the problem ?
Asked by: Menelaos
This is not a common problem but the best course of action would be to make sure both the camera and the lens are updated to the most recent firmware and to be sure the pin connection is clean. If all of those have been done and the problem persists, it is most likely a problem with the mechanism in the lens.
