Sony FE 40mm f/2.5 G Lens
Wide-Normal Portable Prime
A comfortable focal length with an especially portable design, the Sony FE 40mm f/2.5 G is a versatile prime; an ideal single focal length option for a broad variety of situations. This lens's smart build and sophisticated G Series optics mix with intuitive handling and the sleek form factor to make it a go-to option for anything from street to landscape to travel applications.
Matched Set of Compact Primes
Together with the FE 24mm f/2.8 and 50mm f/2.5 G lenses, these three lenses form a cohesive trio with similar styling, image quality, and ergonomics:
  • All lenses prioritize a compact profile with an emphasis on intuitive handling; each features a manual aperture ring along with other tactile controls.
  • The three lenses share the same 49mm filter ring diameter.
  • Matched aluminum finish with stylish focal length and aperture engravings, both aperture and focusing rings, and matching metal lens hoods.
G Lens Series
  • Three aspherical elements promote more uniform sharpness across the frame by suppressing spherical aberrations and distortions.
  • Rounded 7-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Focus Control for Stills and Video
  • Two linear motors deliver quick and accurate autofocus performance, along with capable subject tracking for working with fast-moving subjects. This AF system is also especially quiet to suit its use for cine applications.
  • Internal focusing design limits the overall length of the lens for faster, more responsive focusing.
  • Linear Response manual focus control offers more natural handling and an AF/MF switch is located on the lens barrel for tactile control over this setting.
  • Customizable focus hold buttons are present on the lens barrel for intuitive tactile control and rapid access to select settings.
  • Impressive close-up performance for working with close-up subjects; this lens has a minimum focusing distance of 9.8" with MF (11" with AF), which results in a 0.23x maximum magnification.
Sleek-but-Robust Design
  • Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
  • Lens measures 1.8" and weighs 6.1 oz, making it a great portable choice that's well-suited to both full-frame and APS-C bodies.
  • Dust- and moisture-sealed design better permits working in inclement conditions.
  • Fluorine-coated front element is easy to clean and resists dust, moisture, and fingerprints.
Chiaro Pro 49mm 98-UVATS UV Filter

The Pro 49mm 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.

What is the purpose of the aperture index mark on the aperture ring?
Asked by: Mark
That allows you to easily see what aperture you are in without having to look at the camera. Some people like the old school dials like that since they do not have to keep looking at the camera LCD to see what aperture they are on.

Is lack of OSS a problem for video work? I have the A7RIV and want a compact travel lens for hand-held video and photography. I like the AF/MF features a lot, but lack of OSS is a concern.
Asked by: Chris
The lack of Optical Steady Shot in the FE 40mm f/2.5 G Lens would not be a problem since the A7R IV would already have stabilization built in.

Do focus ring and aperture control ring work ...

Do focus ring and aperture control ring work without lens communication? Since they are built onto the lens is it possible to adapt it onto other camera bodies via adapters that don't have lens communication? For instance, l mount bodies.
Asked by: Yifei
This lens offers control of the aperture via the camera when setting the aperture ring to A or manual control directly on the ring. This is available on Sony E mount bodies only.

So is this Sony's answer to the next iteration of RX1r iii? No need because you have the 7C with one of these?
Asked by: Jay
Great question and we will have to wait and see. I’ve used both generations of the RX1 and both time found myself wishing I had a little more focal length at times and others a wider AOV. Still the appeal of a fixed lens P/S goes back to the Nikon 28&35 Ti’s, the Contax T2 and the Yashica T4. Today we have the Zeiss ZX1, Leica Q2 and two monsters in the category the Fuji X100’s and Ricoh GR series. There is a draw by some for a fixed lens high end camera with minimal options. We’ll have to wait and see what Sony does. Personally I am thinking the A7C with the 40mil would be a perfect companion for my Leica CL and 40mm C Summicron.
