Lumix G 25mm f/1.7 ASPH. Lens with UV Filter Kit Overview

By B&H Photo's
Panasonic Lumix G 25mm f/1.7 ASPH. Lens
A fast, normal prime designed for Micro Four Thirds mirrorless cameras, the Lumix G 25mm f/1.7 ASPH., from Panasonic, is a 50mm equivalent lens featuring a bright f/1.7 maximum aperture for enhanced low-light shooting and depth of field control.
Fast f/1.7 maximum aperture benefits working in difficult lighting conditions and also enables extensive control over focus placement for selective focus applications.
One UHR element and a pair of aspherical elements help to achieve even illumination and sharpness for consistent performance throughout the aperture range.
The optical construction also helps to realize a compact overall form factor, measuring just 2"-long and weighing 4.4 oz.
A Nano Surface Coating has been applied to individual elements to noticeably reduce lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
Stepping motor delivers fast, smooth, and near-silent autofocus performance to benefit both still photograph and movie recording applications.
Rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with shallow depth of field techniques.
Chiaro Pro 46mm 98-UVAT UV Filter

The Pro 46mm 98-UVAT UV Filter is one of Chiaro’s highest-rated protective UV filters with 98% light transmission. It’s ideal for photographers 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. Resistance coating improves the scratch resistance of the glass, and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. 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 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 allows 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 Knurling
Top knurling offers 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.

Im from Canada, will the Manufacturer's warranty still be covered even item is bought in the US?
Asked by: Arman
According to the terms and conditions on the Panasonic Limited Warranty form, the warranty only applies to products purchased and serviced in the United States. As such, for warranty repair issue needs, you would have to send the lens back to Panasonic in the United States, as the lens does not have international warranty repair from Panasonic. If you need international warranty repair, I would recommend considering purchasing one of the SquareTrade Extended Service Protection Plans offered on our website once you click the blue "Add To Cart" button on our website.

How much better in low light is this than the Panasonic 14-42mm f/3.5-5.6 in terms of what ISO the camera needs to be set to get the same results?
Asked by: MASAITIS
The 25mm f1.7 will allow you to substantially reduce the ISO needed for a proper exposure. This will be an estimate as I don’t know exactly what the maximum aperture of the 14-42mm f3.5-5.6 is at 25mm (and you are giving up the flexibility fo the zoom), but it should be approximately f4.5. Increasing the aperture at 25mm from 4.5 to 1.7 is a gain of approximately 3 stops. So what needed ISO 3200 on the zoom will require only ISO 400 on the prime. Or reducing an ISO 800 shot to only ISO 100 (although most m4/3 cameras only go down to 200 or 160 as their native or lowest ISO so you could increase your shutter speed too!). Just looking at shutter speed increases, if you needed 1/50th of a second on the zoom, you can shoot at 1/400th second with the 25mm f1.7. Hope this helps.
