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: 1. I know this product is compatible to the EF-S 17-55 f/2.8 II USM lens per Cannon Website, but can't find anywhere if it is compatible to the Cannon 70D. I am assuming since the 70D is newly released that the compatibility tables haven't been updated. Can you verify that this extension Tube will work with both the EF-S 17-55 f/2.8 II USM lens and the Cannon 70D Camera?

A: Yes, the Canon Extension Tube EF 12 II is compatible with both EF and EF-S lenses, and both the Canon Extension Tube EF 12 II and the Canon EF-S 17-55 f/2.8 II USM lens would be compatible with the Canon EOS 70D DSLR camera (which has both the Canon EF and EF-S lens mount).

Q: 10. I want to scan my negatives with my 5D IV but I don’t have a macro lens. Will this allow me to scan my negatives using my 50 1.4? Or do I need a true macro to scan negatives successfully?

A: You can but you will have to crop a bit to get full image. Your best bet is to get an extension tube set from Kenko, in which you can use 1-3 tubes to get the desired magnification. Click the link below to view; https://bhpho.to/3fMfW3O or the Vello set; https://bhpho.to/3ixtnGA
