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 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.

A: The Vello Auto Extension Tubes for Canon RF-Mount Lenses are compatible with the Canon RF 100mm f/2.8 L Macro IS USM Lens.

Q: 3. can these tubes be used with tele-photo lenses or does it have to a prime lens???

A: Yes... They work great. I use them with a Nikon 135mm f2 DC lens on a Nikon D800e for flowers. This lens has suburb bokeh but does not focus closely enough for flower portraits. Also the Nikon versions are manual only and do not supply exposure information to the camera.

A: Yes they are Chris, all 8 male pins have a spring action..

Q: 6. If 36mm extension tube is used with Nikon AF-S DX 17-55mm f/2.8G ED lens at 55mm what is image size and min. focus distance?

A: It appears that, at the 17mm focal length setting, using the using the 36mm extension tube from the Vello Auto Extension Tube Set for Nikon F on the Nikon AF-S DX 17-55mm f/2.8G ED lens would reduce the minimum focus distance to approximately 3.18 inches (80.7 mm), and at the 55mm focal length, the minimum focus distance will be reduced to approximately 8.72 inches (221.4 mm).

Q: 7. How well will these work with a Fuji 16-80mm XF f4 lens? Could I get really close and crisp? Like say the face of a Bee?

A: The minimum focusing distance on the XF 16-80mm f/4 Lens is 1.15 ft from the subject. By adding both extension tubes to the lenses, you can get very close. However, this would be trial and error.
