The Heliopan 28mm #5 Light Yellow Filter is a basic contrast filter, primarily for use with black and white film, that is primarily used as a haze filter to subtly darken blue tones and increase overall contrast. There is an approximate 1.5-2x filter factor with this filter, requiring an increase of 0.5 to 1 stop 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.

Related Questions and Answers

Q: 1. 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: 2. dose this come with a lens cap and a rear cap?

A: Yes.

Q: 3. How quiet is the lens when focusing? Can you hear it in a silent room or on the microphone?

A: This makes very little noise when focusing. It may be picked by the microphone or heard in a silent room, but it is very close to being silent.

Q: 4. Is the 28mm f2 weather sealed?

A: Yes the Sony 28 mm F2 lens is dust and moisture sealed.

Q: 5. Is this lens good for video?

A: This lens would work for video, yes.

Q: 6. do this len fit in to a300 camera?. thanks

A: The only a300 camera I'm aware of is a DSLR and if that is the case then this lens cannot fit on it as it is an E mount lens.

Q: 7. does this lens have a manual override?

A: The unit does not have a physical switch but you will be able to go manual once set on the body.

Q: 8. Would this work on a Sony NEX 3N? Also, how does it compare to the SEL35F18?

A: Just to correct: better check what camera you have. The Nex 3 3c etc. are APS C cameras, not four thirds; there was a 5n which is a 16megapixel aps c camera. The lens will fit all of these cameras, but the APS C camera sensors are only half the size of the image the lens is designed to produce so a lot of the image is wasted. The Sony Zeiss 24mm f1.8 is a wonderful little lens, designed for the APS- Emounts. I have it and love it. But remember as you figure the field of view, that an APS C camera gets coverage out of a lens comparable to a full frame camera with a focal length of 1.5 more. i.e. a 24 mm aps c lens has the same field of view as a 36 mm full frame.

Q: 9. How good is this lens for video on Sony A6000, given that it does not have optical image stabilisation?

A: The build quality and picture/video quality is amazing. Because the a6000 is a crop sensor, this 28mm acts as a 42mm equivalent. On a tripod or in steady hands the lens is fine. If you're running around (with any lens) with no stabilization, you will produce a shaky image. Another thing to consider is the digital accelerated focus ring. If you will be using this on a rig with a follow focus system, keep shopping. This focus system makes it nearly impossible to do rack focusing or replicate a previous shot. To recap: on a tripod or in steady hands shooting mostly still subjects, this lens produces a wonderful image but, for other video purposes I would not recommend this lens.

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.
