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. What is the effective aperture loss when using the tubes?

A: The Kenko Auto Extension Tube Set DG for Canon EOS Lenses does have light loss. it does depend on the lens. The formula for that is, Ef = Effective f-value (that is what you get after adding extension tubes or bellows) If = Indicated f-value (that is shown on your lens or display, the one that is set on the lens) F = Focal length of the lens Ex = Extension (total length of the extension tube or bellows) The formula is: Ef = If x (F + Ex)/F

Q: 6. Can these be used with the Nikon 2.0 teleconverter on a Nikon 80-400 zoom?
