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

A: I use this often with a Sigma 150-600mm Contemporary Lens to shoot dragonflies and it works fine. As others have mentioned infinity becomes a lot closer.

I took off the EF 25 II, got the shot of the turtle, put it back on and got back to my dragonfly hunting.

Q: 5. What kind of results can one expect using Canon's 70-300L? How much closer is focusing improved?

A: Basically you will use this so your Canon EF 70-300mm f/4-5.6L IS USM Lens will be able to focus closer than the lens's native close focusing distance of 3.94' / 1.2 m. We were not able to find information as to how much closer but we would guess that bout 2' would not be unreasonable. People with telephoto lenses by this to do exactly this, get a closer focusing distance. This can be an excellent too.

Q: 6. I know extension tubes make the widest focal length zoom in because it spaces it away from the lens.By what factor with the Extension Tube 12 increase the focal length by?Ex - Factor of 1.5 making a 50mm now a 75mm.Help!

A: The Extension Tube EF 12 II wouldnt have an effect on the angle of view or focal length of the lens. Extension tubes will simply decrease the minimum focus distance of the lens, allowing you to focus closer to a subject. So, a 50mm lens would remain a 50mm lens, and would still have the same angle of view.
