The Heliopan Bay 6 Close-Up +1 Lens is 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 6 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.

Q: 7. Hello. I'm looking for a ring flash for dental photography for D810 frame. What would be the advantage of R1C1 over the R1 system? Do I need to purchase a separate adaptor for an 85mm or 105mm lens? Thank you

A: The primary difference is one has the flash and mounting ring the other has a command unit. You can dispense with the command/control unit (C1) if you are using D810. You need to go to the D810's menu and look up flash and set up the channels to control the flash units. As a whole kit the R1C1 is obviously more expensive. But if you are using other flashes like SB910 and do not wish to mess with the on camera flash menu every time, R1C1 will allow you to have a specific set up that once attached it will give you consistent result you are looking for.
