The Heliopan Bay 1 Close-Up +3 Lens Accessoryis 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.

Q: 1. 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: 2. Will this fit a nikon 18-55 mm kit lens for the d3200?

A: Yes it will. To ensure if a filter will fit your lens look for the lens diameter written on the outside ring of the lens. The Nikon 18-55 mm has a diameter of 52 mm that matches this filter. Works very well. Enjoy!

Q: 3. 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.
