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: 1. will this work with the eos xsi efs 18-55 and the 75-250 lense ?

A: Kenko DGs should work fine with all EF and EF-S lens and camera combinations, same combinations as without the tubes. Note that magnification increase will be less with longer focal lengths.The math; extension tube length divided by lens focal length = magnification increase.This increase gets added to the lens' native magnification.Barely worth mounting up to your 75-250 especially when zoomed out, should be exceptional with your 18-55.Depth of field gets very very thin at close focus/high magnification, expect to stop down on a tripod and focus stack. Subjects in motion like bugs, flowers swaying in the breeze are tough subjects, done every day though, obviously not impossible.
