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. When I order, do I specify MM DIAMETER - that doesnt seem to be requested?

A: You will need the correct camera mount to suit your camera and lenses. The extension tubes are pre-set but can be disconnected into 2 separate units, or used together. As they increase the distance between the camera and the rear of the lens, the image is magnified on the sensor. They are good to experiment with as it opens up a new dimension in photographing small to minute subjects. Enjoy.

Q: 2. I just received the Vello Auto Extension Tube Set for Nikon. I have a D90 camera, and I'm using a Nikon DX AF-S Nikkor 35 mm 1:1.8k G lens. I tried using the 12mm extension tube and see nothing through the view finder. I tried it outside with plenty of sunshine, and yes, the lens cap was off, but I still didn't see anything. Also, I know you can't set the aperture with the tubes, so can I still shoot in manual or do I need AUTO?

A: Everything should work fine with what you have. Since this is a Auto version and not the Manual version, you can control the aperture of the lens with the tubes in place. Be sure that that on the camera, the aperture is open all the way. While the image will be dimmer than without the tubes, you should see clearly enough.If you still have an issue, please email us with your experience. prophoto@bhphoto.com.

Q: 5. Are these for full frame as well, or only for APS-C?

A: These Vello Auto Extension tubes can work with both FX and DX Nikon Z mount cameras.

Q: 6. 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.
