The Heliopan 49mm Linear Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° from the sun.

Single coatings on both the front and rear offer protection to the glass and help to improve light transmission and image quality.

Constructed from Schott glass for optical clarity.

Brass filter ring helps to prevent jamming and provides additional strength.

Dual threading with 49mm front filter threads permits combining with other filters.

Q: 1. Is there a collar that makes the new Z lenses backward compatible with existing F mount cameras (Nikon 850)?

A: No. You physically cannot adapt Z lenses to F mount cameras, the sensor to flange distance will not allow for this.

Q: 2. Can the L-fn button be used for auto focus, where the L-fn button focuses and the shutter button takes the photo?

A: Yes, you can customize the L-Fn button to AF-ON. So you can focus with the lens L-Fn, and use the shutter to take the shot. This will be in the menu, under ( CUSTOM SETTING MENU ) Controls F

Q: 3. I understand the limitations using this on an Alpha 7r. But what lens is sold with this configuration that does not have those limitations and is a full frame lens? Either Sony or Zeiss. Thanks

A: Unfortunately there is not a full-frame version or equivalent of this type of lens for the full-frame E mount at this time. Below are a link to all the current full-frame lenses available for the camera system for you to regard:http://bhpho.to/1pq1pyK

Q: 4. I have this mounted on an FS-7, but I can't get it to do a slow creeping zoom. At the slowest speed on the handle zoom it is still too fast - any suggestions without using a separate zoom controller?

A: Yes, that is the slowest it can zoom without getting a separate zoom controller.

Q: 5. How is the weight on the camera body, is a tripod mounted needed on the lens?

A: The lens weighs as much or more than the body. Most of my shots are hand held. My arms are firm against my rib cage and I exhale slowly while I take the shot. There is a slight recoil but the stabilizer works well. I would like the images to be sharper and more crisp. The polarizer seems to make the colors brighter and a little crisper.I have a Sony G 90mm with macro. It does to work for me and I am planning to sell it back to B&H. The 24 to 240 works well for me and travels with me everywhere. I use a tripod for some nature shots or low light situations. In Cathedrals, I use HDR to shot interior shots and rarely use a tripod (not allowed in most places with lots of people).Have fun and enjoy Japan.

Q: 6. Will this work on the 17mm ttartisan lens for aps-c sensor and not induce vignetting?

A: It should be fine and not vignette using it on a 17mm lens on an APS-C camera.

Q: 7. How will the VR function with the in body stabilization of the the Z6 and Z7 bodies? With both function together?!

A: yes, and yes, both will work together

Q: 8. Does this lens change length when zooming?

A: Yes it will , this lens is external zoom

Q: 9. How well does this lens work in low light?

A: This isn't an exceptionally wide aperture, so if low-light performance is your top priority, I'd recommend looking at the 70-200 f2.8, or changing your body to an A7s. However, I've been shooting with this as my everyday lens on my A7ii for over a year and I'm very satisfied with the performance in all conditions. I recently tested it against a G-master lens and was surprised that the difference in the image quality was extremely marginal.

Q: 10. Is this actually an internal focus camera?

A: Hi, the NIKKOR Z 24-200mm f/4-6.3 VR lens is an internal focus lens.
