This Hoya 40.5mm HMC Close-Up Filter Set II offers the ability to achieve macro-like results with camera lenses that have 40.5mm front filter threads. A close-up filter is a magnifier that optically decreases the focal length of a camera lens placed behind it. This effect lessens the minimum focus distance between the camera lens and a subject. Magnification can then be obtained by decreasing the distance between the subject and the combined camera lens and close-up filter.

The magnifying power of a close-up filter is indicated by its diopter strength. A close-up filter with a higher diopter number provides more relative magnification and can be combined with other close-up filters to increase, or fine-tune the macro effect. These close-up filters have diopter strengths of +1, +2, and +4.

Each surface of the filters in this Hoya HMC Close-Up Filter Set II is constructed from optical glass which includes three layers of anti-reflection coatings that offer improved clarity as well as more effective prevention of internal ghosting and reflections. These close-up filters each provide approximately 97% average light transmission and feature an aluminum-alloy filter ring for durability while remaining lightweight.

Related Questions and Answers

Q: 1. Can you use these rings to duplicate slides?

A: Yes, with the right lens. Your slides will have to be evenly back lit and you will also need to have the system optically centered, aligned and stable. Extension tubes are made for general close up and macro photography. If you only want to copy slides check out "slide copiers" listed at B&H.

Q: 2. Do these diopters fit the Bright Tangerine Misfit Kick?

A: Yes, The Lindsey Optics 4 x 5.65" Brilliant² Tray Mount Close-Up Lens Set will work with the Bright Tangerine Misfit Kick.

Q: 3. Is it compatible with Nikon 850? Any other better kit, suggestions?

A: The FotodioX Macro Extension Tube Set for Nikon F-Mount Cameras: for Extreme Close-Up Photography is a manual macro extension tube set that would be compatible for use with the Nikon D850 DSLR Camera. If you want a set of macro extension tubes that will retain automatic electronic communication between the camera and lens (which would allow you to retain autofocus and automatic exposure capability), the Vello EXT-ND2 Auto Focus Extension Tube Set for Nikon F-Mount Camera and Lenses, B&H # VEEXTND2, would also work for your usage needs.

Q: 4. Are these tubes auto or manual? If so is there a specific Sony amount?

A: These are manual and made for Sony E mount. For A mount you would want these; B&H # FOMACUBESNYA

Q: 5. How close will it get to a jumping spider ?

A: you can get few inches to the subject

Q: 6. Would these work for video on a Sony FX6 with Rokinon glass? The lens is 100% manual, so no loss of function to worry about.

A: The FotodioX extension tubes do work with the FX6. If you're using manual lenses it should work fine.

Q: 7. Can I use the EF-M for canon M50 with kit lens?

A: Yes these tubes have an EF-M mount for use with cameras such as the Canon EOS M50.

Q: 8. Will this set work with the Canon 70D?

A: Yes it will. Fotodiox lists this as compatible with the Canon 70D.

Q: 9. Will these work with EF-S STM lenses?

A: The FotodioX Macro Extension Tube Set for Canon EOS (EF, EF-S) can mount a EF-S STM. But everything will be manual. Focusing and Aperture control will be all manual. With a Canon lens you would not be able to control the aperture at all. And whether you can focus the lens while on the extension tubes will depend on the specific lens you are using. Some lenses need to be attached directly to the camera to have focus control. For automatic Focus and Aperture control I would look at the FotodioX Pro Auto Macro Extension Tube Kit for Canon EF & EF-S Lenses linked here. https://bhpho.to/34CeJZN
