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

Q: 6. I have a 24-70 and a 70-200 (both Sigmas), will this extension tube set work with my lenses? I need to get some real detail shots of rings...aka macro.

Q: 8. will these work with lenses wider than 50mm?

A: Absolutely! I use them with my 18-55 zoom, and my 11-16 zoom, and my 35 mm prime.

Q: 9. How about using the extension tube while shooting at 200mm or more? Can it make a telephoto macro? Or it will work well at lower or wider focal length only?

A: These tubes will give you a shorter minimum focus distance, so it will be kind of like macro at somewhat of a distance. Not sure which 200mm lens you are using, but if you have a heavy monster, that might put a lot of stress on the mounts.

Q: 10. I have the non-DG set. What does the DG upgrade do - functionally? The upgraded chip means nothing to me.

A: I have the Kenko DG set, and they provide auto-focus and auto-exposure with my Nikon D90 & D7100, along with Nikkor lenses. Each one of the extension tubes are equipped with the electronic contacts to convey data from the lenses to the camera and back. I have been completely satisfied with them.
