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: 6. I know of Nikon F camera body mount but not Nikon F V2 mount. Please explain the difference, if any?

A: The V2 isn't referring to the F-mount, but the version of the extension tubes. The V2 (version 2) of the Nikon F-mount extension tubes seems to be a slightly newer design, and might potentially have slightly better electronics.

Q: 7. I just bought these tubes for my Nikon D7100. I cannot set the Aperture with these tubes. I'll adjust my camera to F/11 and the aperture remains wide open at F/3.5. You can see the aperture not move while you scroll the aperture adjustment wheel. Could it just be I have a defective set???

A: The aperture does not move when you scroll, it opens or closes only when a photo is taken. You may test this by setting the aperture first to f/22, which should give you a fairly dark image. Then, try setting the aperture to f/5.6, which should produce a much lighter image.

Q: 10. I do a lot of long exposure photography (i.e. 1 to 2 minutes) with a high megapixel full-frame camera. Would this tripod keep a 70-200mm lens absolutely steady in a moderate wind for long exposures, or should I get the 34L version for more stability?

A: Yes, the Really Right Stuff TVC-24L Series 2 Mk2 Carbon Fiber Tripod should be suitable for your usage needs. The flat pate on the top of the tripod has a hook on the bottom that would allow you to hang your tripod or other ballast such as a sandbag or other weight to increase stability if you will be shooting in windy conditions. You would still need to purchase a tripod head that is strong enough to support the weight of your camera/lens for your planned usage needs.
