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: 8. It looks like the 7mm tube is used in conjunction with two other pieces. Does using the 7mm ring mean the lens will be displaced 7mm from its normal position? Or is there some overhead from the other components?

A: Well, I purchased a set, so I can answer my own question. The camera mount tube and the lens mount tube are always used, and they move the lens out by 16mm. Any combination of the other three rings can be inserted in between them to increase the displacement. The customer should be able to learn this 16mm number from the description online. It's not even in the manual. I had to pull out calipers and measure it myself. no rings: lens is displaced 16 mm7mm: 23 mm displacement14mm: 30 mm displacement28mm: 44 mm displacement

Q: 9. Can this be attached to the MC-20 teleconverter? i.e. Camera=MC-20=Viltrox = lens

A: I would not recommend using the Viltrox Automatic Extension Tube Set for Micro Four Thirds on the Olympus MC-20 M.Zuiko Digital 2x Teleconverter. The Olympus MC-20 M.Zuiko Digital 2x Teleconverter is designed for use on specific Olympus M.Zuiko telephoto lenses to increase the lens' focal length, whereas the Viltrox extension tubes are designed to increase magnification for close-up photography, but causes you to lose focus at infinity. The two items are not typically used together, and Viltrox has not tested the use of their extension tube with the Olympus teleconverter.
