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 T12 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: 7. Mine doesn't seem to work. Tried it with a EF 100mm f/2.8L Macro L series and a Canon EF 16-35mm f/4L. Couldn't get it to focus no matter what I tried. What am I doing wrong?

A: It adjusts your backfocus to allow for a macro image. You will find that with a zoom, you can use your zoom control to help focus - it will change your focal plane. For fixed focal length lenses, you have to physically move to find the distance at which the target will be in focus, almost like you are using a lens with a nearly fixed focal distance. That's because you shifted the lens out of the focus plane

Q: 10. is the Canon EF 25 II Extension Tube compatable with EOS Digital Cameras?
