The Heliopan 28mm #22 Orange Filter is a basic contrast filter, primarily for use with black and white film, that strongly darkens blues and greens, increases overall contrast, and is often used for outdoor photography to emphasize contrast and shadows. It is also well-suited for decreasing atmospheric haze when photographing with long lenses and to smooth skin tones for portraiture. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.

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.

Q: 1. How fast is the auto focus when shooting video on the As7ii? I want to use this lens on a gimbal so need pretty good auto focus.

A: I use a 49mm UV filter on my lens. Im sure the ND filter would be the same size.

Q: 4. Does this lens support the steadyshot image stabilization when on an a6000?

A: No. And this is not the lens you would want for an A 6000. Quick Lesson. Steady Shot or image stabilization (IS) is a feature added to a camera, either in the body (In Body Image Stabilization (IBIS)) or in the lens itself. The A 6000 does not have IBIS so you have to rely on purchasing lenses that do have it. For example, my favorite for my NEX 7 is the F 4 16-70 zoom that does have IS. (Note, the different manufacturers call image stabilization by different names. VR is Nikon. OSS is Sony, etc. If you want a pretty high quality prime with OSS made for the A6000 then the Sony F 1.8 50 mm OSS is the lens you want. Or wait til Sony comes out with an APS C camera that has IBIS ---

Q: 5. How quiet is the lens when focusing? Can you hear it in a silent room or on the microphone?

Q: 7. How does this lens compare to the Sony FE 35 f2.8?

A: Hi--it's difficult to compare two lenses with different focal lengths, but these two are somewhat similar in optical quality, with the 28mm lens being somewhat better optically, as well as having a wider maximum aperture of f/2 vs f/2.8 for the 35mm lens.

Q: 8. Is this compatible with the Sony A7SII?

A: This is my default walking-around lens for my A7sii. I wish it was a little more compact, but it shoots really nice images, especially when I use the lens compensation in Lightroom. I wish it had manual aperture on the lease and a AF/MF switch, but no complaints otherwise.Hard to go wrong for the price.

Q: 9. dose this come with a lens cap and a rear cap?

A: Yes.

Q: 10. On a Sony a6000 series camera how does the image quality of this lens compare to that of the Sony Zeiss 24mm f/1.8 lens?

A: Both lenses will give you excellent image quality. It really depends if you could use the half stop more of light the 1.8 gives you over 2.0 and if you prefer a little bit of a wider shot. If you said yes to both of these, then the Zeiss will be your better option.
