The Heliopan Series 8 Infrared RG 610 Filter is used for infrared photography with digital cameras and specialized infrared film. This nearly opaque filter blocks all visible light up to 610nm, enabling recording of subject matter and scenes that are not visible under normal conditions. Due to the nature of infrared photography, the filter factor for this filter is highly variable and depends largely on the ISO sensitivity in use and lighting conditions. Additionally, it is recommended that auto-exposure and autofocus functions are disabled during use for greater control over the results.

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 enhanced durability.

Related Questions and Answers

Q: 1. Center column is useless for me. Can the center column be removed to reduce the weight further?

A: Yes, one can remove the center column to reduce the weight of the tripod..

Q: 2. Is the swivel foot removable? If so is there a 3/8 16 threaded socket?

A: Yes, it is removable and is 3/8".

Q: 3. The center column on this tripod has a rubber cap that actually screws off. Can this cap be replaced by another component that provides a hood for weighting the tripod?

A: B&H offers the Gitzo G-2020 hook which looks like it would work.

Q: 4. Does this monpod have a wrist strap?

A: It does, and it is easily moved from side to side ( e.g. when an attachment for your camera dictates one side be used).

Q: 5. Can the center column be removed and inverted like the traveler models? I know it can be removed and just the base reinstalled for low shots. But I may wish to shoot with the camera suspended beneath the legs at some point. Thanks in advance.

A: Yes this is easy to do. There is a threaded end cap with the hook to hold a weight on the bottom of the center column. This is removed and the column comes completely out once you loosen the locking collar. It can be reversed and locked in place using the same locking collar. There is a guide pin which prevent rotation of the column. Rotation of your camera is accomplished with the head you choose. I have the small ball head and this has worked well. The entire combination is very light and still rigid and works well for travel.

Q: 6. Is it safe to assume that the Rokinon 14mm Series II lens will work on a Canon R5 with the Canon Ring Mount Adapter EF-EOS R?

A: Yes, the Rokinon 14mm f/2.8 Series II Lens for Canon EF is compatible with the Canon R5 with the Canon Ring Mount Adapter EF-EOS R.

Q: 7. Confused about whether the gt2545t has one or more intermediate click-stops for the legs. Reviewer here says no, but I've found nothing anywhere else to confirm that?...Thanks!

A: if you're talking about the stop(s) that determine the leg angle, there are two, one which puts the tripod in a tall position and one which puts it in a very low position - I only use the low position with the legs fully collapsed as I think otherwise it would put too much sideways stress on them. I have an FLM head on it and it still fits (snugly) in the carry bag. I've taken it to Japan with me and put everything from a 1937 folding Zeiss to a 4 x 5 Technika on it and I'm sure it would be OK for my 5 x 7 and even my 1903 Seneca wooden 8 x 10. I've used it with a C100 Canon video cam as well - not as resistant to twisting as a real video tripod but reasonably OK. Love it!

Q: 8. Is it compatible with Canon EOS 5Ds?

A: No, it is not compatible.

Q: 9. what is the distance between the legs measured from the floor when at maximum height? I would like to know how much space it takes up when at maximum height

A: The distance from the outer edge of the feet when tripod is fully extended to maximum height is 43

Q: 10. Does it come with any batteries?

A: No this will come with just the battery grip.
