Rosco Fluorescent Lighting Sleeves/Tube Guards are a very reliable and cost-effective system for easy control of tough lighting scenarios- especially under fluorescents. In addition to the financial benefits of the sleeves, they protect against the potential disaster of glass shattering by containing the lamp within the end caps.

Rosco sleeves are constructed of a solid polycarbonate tube within which is held the specific filter. The choice of filters and combination of filters is endless - there are complete Roscolux, Cinegel or E-Colour color filter lines - something for every venue, every photographer, every cinematographer.

For T5 Lamps    Over 300 Colors Available    UL94HB Rated Polycarbonate    End Caps Protect From Shattered Glass    Easily Trimmed with Scissors

Available in sizes for T12, T8 and T5 fluorescent lamps

The T8 and T5 sizes contain a UV filter that minimizes fading

All standard sizes (2, 4, 5, and 8') are easily trimmed to accommodate any size lamp

Related Questions and Answers

Q: 1. Will these allow you to reverse your lens for even greater magnification? I'm sure you'd have to shoot full manual if you did.

A: No, a reverse adapter is a different accessory and method to get macro closeness. If you are using G lenses with no aperture ring, the reverse method is problematic because you wont have aperture control. These tubes send the aperture setting to the lens from the camera.

Q: 2. I have a Nikon D300 and want to use my Nikon 50mm f/1.8D lens. Just starting to play with the idea of macro for fun. Will these work? What would be another lens size to add for these?

A: These will work. Autofocus and data transfer between lens and camera is maintained. As another answer mentioned, a 100mm lens would be a good one to try as well.

Q: 3. I have a Nikon D3200 and a Sigma DC 18-250 lens, 1:3.5-6.3. Are these extension tubes compatible with this set up and if they are, are there any issues at all that I should be concerned with?

A: These extension tubes will be fully compatible with the D3200 and Sigma 18-250 lens. The extension tubes will allow you to focus closer than the set minimum focus distance of the lens. There will be some light loss when using extension tubes. Adding about 40% of the lens focal length will result in the loss of 1 f/stop. Additionally, focus to infinity will be lost.

Q: 4. Will these tubes work on D810 with Zeiss milvus macro or Zeiss 135mm f/2?

A: i do have an 810 but i never use with it i use with my d3s 700 and 7000 i know that it work with fix lens and zoom auto focus and most nikon camera it a good buy for me works great make sure you understanding how to use it .youtube.

Q: 5. Are the size of the extension tubes based on the camera or the lens? I have a Nikon D750 and a range of lenses. Want to make sure these will work. Thanks!

A: I bought these a few years ago. They are based on the lens mount -Nikon F mount for instance. I own Nikon, sigma, and Tokina lenses and the D500/D5300 and all function properly.

Q: 6. i see that these are compatible with the Canon EOS M, M2, M3, and M10 cameras, how about the M100? I'm hoping to build skills, as well as enjoy the sheer pleasure of photography with this new(to me) camera

A: Yes, it will work.

Q: 7. Does it communicate VR function?

A: Yes the VR function works with these tubes.

Q: 8. Hi i ve got a canon EOS 6OOD with 18 -55mm lens. Will the kenko tubes set work?

A: They work with my Canon 6D.

Q: 9. Will these tubes work with the D810 and the 60mm Macro?

A: Yes, this set is compatible with your D810 and the 60mm micro lens.

Q: 10. Are these tubes compatible with a Canon 70D and a Sigma 105mm macro lens?

A: They should operate fine. The only electrical components inside are simple pass through contacts for passing lens information to the camera body.There are no optical components inside, just air.There are some compromises involved with macro tube use.When in use, focus to infinity is usually not possible.Working distance becomes very close.Depth of field/plane of focus becomes very thin.Magnification = Total Extension / Focal Length + Lens' native magnification.In the case of your Sigma 105 macro, native magnification is 1:1.With the full 68mm stack of Kenkos, you'll get 68/105=0.65x additional magnification, 1.65x total. The shorter the lens' focal length, the greater the additional magnification.For example, using the full 68mm set with a 40mm pancake lens, magnification increases from 0.18x to 1.88x.Downside remains depth of field. 68mm extension with a 40mm lens results in depth of field the requires either a subject (and its plane of focus) be parallel to the sensor and/or focus stacking multiple frames. So, not sure what you're hoping for adding these to a 105mm macro lens, there will be some additional magnification, nothing radically different as with a shorter focal length.Can't help with crop factor differences, no experience, no interest.
