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: 5. In one comment it says the Nikon version does not pass exposure info to teh camera. Is that correct?

A: From my experience it depends on the lens the extension tubes are being used with. They do work fine and pass all data for exposure and focus if the right lenses are used. So it is a matter of lenses working correctly rather than Nikon camera bodies. I bekieve you will always find that some lenses work better with extension tubes than others.
