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: 5. can these tubes be used with canon 100mm-400mm zoom lens?

A: The Nikon PK-13 will not be compatible with G type lenses that do not have aperture rings.

Q: 10. 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.
