The Heliopan Bay 1 Close-Up +2 Lens Attachmentis a convex diopter designed to decrease the minimum focus distance of any lens in order to produce a shorter working distance for close-up photography. Available in varying strengths, close-up lenses also feature Bay 1 front filter threads for combining two or more filters to fine-tune 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 durability as well as jamming prevention.

Convex lens design and +2 dioptric strength lessens the minimum focusing distance of any lens for close-up shooting.

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 mounts with Bay 1 front filter mount permits combining with other filters.

Related Questions and Answers

Q: 1. If I am using a TLR camera, do I need to buy two of these? One of the taking lens and one for the viewing lens? Or is it a set?

A: Two of the Heliopan 72mm Close-Up +3 Lens should be used on both lenses on the TLR camera. Note, that it has not been tested and adding a filter to each lens might not fit well because of the thickness of the filter frame.

Q: 2. What is magnification for this lens? I'm looking for x1.5 up to x3 (similar to Nikon 5T and 6T). Thank you

A: According to the forum for this product on the Nikon USA website, The magnification factor of the D-SLR Close Up Lens (52mm) is 0.44x. (Answered by a Nikon USA representative.)

Q: 3. This will solve the field curvature of the CV 35 mm 1.7 on mirrorless cameras?

A: We are not sure of what lens you are asking about. Maybe the Voigtlander Ultron 35mm f/1.7 Aspherical Lens (Black) B&H # VO3517K? Also we are unaware of a close up lens ameliorating lens aberrations. Indeed we only know of them introducing them. In order that we may further assist you, please write us sales@bhphoto.com.

Q: 4. What is ES 77 No.3?

A: This is the strongest option for close-up shooting. This filter is essentially a very high quality diopter that allows a lens to focus closer then it would normally focus. A close-up filter is an alternative to using a focus tube which would also accomplish the same goal but with a bit more light loss.

Q: 5. Is Heliopan Digital ES 77.no3 macro?

A: It works similar to macro in that it allows you to get closer to a subject, lessening the minimum focus distance.

Q: 6. Will this affect picture quality if I attach it to the sigma 18-300 all the time ?

A: You should use it only when trying to shoot macro. Otherwise AF will not work properly.

Q: 7. How better is it to compare to Vivitar Close Up filters? What minimum focus distance would be for Nikon 40mm (if it has 0.29mm without any filter) Thank you!

A: It is a matter of optics. Nikon is noted for optics. And it will be better than other brands. These are also other good models, https://bhpho.to/3CkkJES

Q: 8. Will this fit my Nikon d3500 lens?

A: If you're referring to the 18-55mm lens that comes with the the Nikon d3500 than the answer is no it will not. The filter thread diameter on the 18-55mm is 55mm and this close up filter is 52mm.

Q: 9. Will this work with sigma 70-200?

A: I don't think so. Pretty sure that was made specifically for the Sigma 18-300. It's basically a big magnifier that screws onto the end of the lens, which has a 72mm filter size. Check the filter thread size of your 70-200; if it is 72mm maybe it'll work.

Q: 10. Hi I have a Nikor 18-200mm lens. Which close-up filter shpuld I use.? 72mm?Is it the same a as wide angle converter ?

A: Yes, you would use the 72mm because the Nikkor 18-200mm has a 72mm thread. This filter is not the same as a wide angle converter, but you can get a 72mm wide angle converter for the lens.
