Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. Lens with UV Filter Kit Overview

The Panasonic Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. Lens with UV Filter Kit from B&H bundles the sleek portrait-length prime with a 37mm UV filter.

Panasonic Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. Lens

A standard portrait-length prime, the Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. from Panasonic is an 85mm-equivalent lens designed for the Micro Four Thirds system of mirrorless cameras. One aspherical element is incorporated within the optical design, which helps to control spherical aberrations and distortions for enhanced sharpness and accurate rendering. The f/1.7 maximum aperture is particularly beneficial for selective focus imagery, and also aids shooting in low-light conditions. Further cementing its place as a versatile tool for portraiture, the rounded seven-blade diaphragm produces a smooth out-of-focus quality when making shallow depth of field photos and movies.

Complementing the optical attributes is a fast stepping AF motor and internal focus design, which provides smooth, quiet, and responsive focusing performance for intuitive handling. The POWER O.I.S. (Optical Image Stabilizer) also benefits hand-held use by compensating for the effect of camera shake for sharper imagery.

Chiaro 37mm 95-UVAT UV Filter

The 37mm 95-UVAT UV Filter is one of Chiaro’s highly-rated protective UV filters with 95% light transmission. It’s useful for photographers of all levels who demand high-quality glass and other essential features for great image fidelity and construction.

To achieve 95% light transmission, Chiaro uses highly-polished optical glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. A hard-anodized aluminum filter ring is designed to screw on and off effortlessly, and it’s thin to prevent vignetting when used with wide-angle lenses.

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 you can choose the perfect filter for your lens and photo session.

95% Light Transmission
Protect your lens while maintaining optical quality. By using highly-polished optical glass, Chiaro offers a 95% transmission rate. And the company verifies the ratings with ISO certified lab testing.
Polished Optical Glass
Highly-polished glass is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is polished for flatness that ensures great 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 Knurling
Top knurling is designed to offer a firm grip on the filter when you're attaching or removing it.
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.

Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. Lens with UV Filter Kit Reviews

Tiny Lens, Great Photos!

By Timothy

I was very surprised when this lens arrived in the mail. It was so small! I thought to myself, surely this isn't the right lens. Don't get me wrong, the reason I love the Micro 4/3's system is because it's small, but even still, this lens on my LUMIX GX8 feels so small. And I love it! Portability is amazing for this little guy. Auto-focus is lightening fast. And the focus ring for manual focus is smooth as butter. This is a great lens to add to your collection. 100% recommended!

One of my favorite new lenses

I'm fairly new to the world of prosumer cameras. I started my videography/photography journey with an iPhone. Last year, I made the switch to the GH6 and I recently bought this lens for a client shoot. First of all, I love how compact this thing is. It fits in the palm of my hand (no joke). It is incredibly sharp and I love the look of the f1.7 aperture. I still have a lot to learn on this journey, but I think this lens is going to make it fun!

It's an OK zoom lens.

It's an OK zoom lens. I would prefer something with a lower apeture.

Small, light, fast focus, close focusing, Sharp. Comes with lens hood, case. Nice control over depth of field. Cons? Perhaps the tiny 37mm filters needed. Nothing a step up ring won't fix. Need a portrait lens for m4/3? Get this lens.

Powerful, Yet Tiny

I was so astonished when I unpackaged this lens as to how small it was. Even though I was well aware that this is for a Micro 4/3 camera body, I was still surprised. That being said, this little guy is a work horse!!! I have been using this on my LUMIX DMC GX-8 and it's been wonderful. Having essentially an 80mm in such a small package is so liberating and portable. I love the Micro 4/3 system because it is so small. This 42.5mm is even smaller than my 12-35mm Kit lens (which I also love). The auto focus works lighting fast with the lenses, and the bokeh I'm getting is just *chef's kiss". I bought this lens used from B&H to save a few extra dollars, but I can say with confidence that this little guy is 100% worth the full price.

Realizes the Promise of Micro 4/3rds

By Lance
Rated 5 out of 5
Date: 2023-05-29

We like Micro 4/3rds because the lenses are typically smaller for the same field of view as full frame. This lens is the 4/3rds equivalent of an 85 mm portrait lenses for full frame. But this lens much smaller and lighter than any 85 mm FF lens It looks great on a Lumix GM5! I can hang it around my neck all day long without fatigue. And with image stabilization built into the lens, it makes up for the lack of focal plane stabilization in the GM5. And what a performer! My test shot was wide open, F/1.7 and I can't see any lateral color in the crop in this glinty high contrast image, just a tiny smidge at the pixel level. And what a price too! I would love to see Lumix make a prime lens like this for 75 or 100 mm. A 100 mm F/4 prime with OIS for GM5? I would buy that. Now if only Lumix would make their Micro 4/3rds cameras smaller too. I love the G9, but it's the same size or larger than most full frame cameras.
