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. How is the image quality using those Extention Tubes vs a micro lens? In other words, does the tube degrade image quality vs bare lens?

A: A real macro lens has some advantages over a "standard lens" and extension tubes. If your subject is perfectly flat (a postage stamp, for instance), a real macro lens (one designed to focus 1:1 scale or close to it) will be sharper in the corners. If the subject has depth (like probably 99% of the stuff you take pictures of with a macro lens), then you NEVER have enough depth-of-focus. If you want even a few millimeters of the subject in focus at 1:1 scale, you need to set the lens to a REALLY small aperture. My Nikon macro lenses have an f32 setting. Most standard lenses can only stop down to f16. f32 is a big advantage. Using an extension tube to increase magnification just increases your need to use smaller and smaller apertures to keep anything in focus. BUT... a 50mm to 100mm prime lens and ext. tubes is still a great way to get high-magnification shots. You would have to take a lot of close-up images to justify the difference in cost between tubes and a real 105mm macro lens. I would certainly just use tubes and a 50mm lens while saving up for a 105mm macro. Don't waste your money on a macro shorter than 100mm. The extra subject to lens distance you get with 100+mm focal length is really important to good subject lighting, among many other things.

Q: 2. are these tubes compatable with a canon t4i?

A: Yes, they are.

Q: 3. Can you use the extension rings with a true macro lens?

A: Yes you can. I have a Canon 100mm macro that I have used the extension tubes with and still get beautiful pictures - even of butterflies that dont stay still very long come out sharp. I would recommend this product. I keep it with me all the time.

Q: 4. I have a 100 mm macro lens and want to use these extension tubes with it. Is the seal between THE TUB AND THE LENS secure and tightly fitted? Another set I have is loose and I cannot use it for fear of lens falling off..This probably applies to other lens also and not just the 100 mm macro.. Thank you.

A: I'm using a set of Kenko Extension tubes with a 100mm 2,8L lens and its not loose at all.

Q: 5. Hi, I own a GH4 with a panasonic 20mm 1.7, and a 45mm 1.7. Will it work with the kenko extension tube?

A: I used mine on an Olympus OMD-EM10, and they worked very well. They should work on your Panasonic, with a few caveats. Since the Olympus has sensor-shift image stabilization, I could not test to see if they have the connections for IS on Panasonic lenses. Also, you will have a very short working distance with those lenses. The 45 mm should work OK, but the 20 may be a little short. I mainly use mine with a 60 mm macro, but have used them on a 12-40mm zoom (mostly at 40mm) and also with the Panny 100-300 zoom. The longer the focal length of your lens, the better the working distance, which is especially important for insects. The Kenko tubes seemed well built, so I bought a set for my Nikon camera too.

Q: 6. is the kenko extension tube set compatible with Sony Mount A-99.... which is a DSLT camera.regards

A: Yes, the Kenko Auto Extension Tube Set is compatible with the Sony A99.

Q: 7. Will this extension tube work with the Sony E-Mount 18-200mm f/3.5-6.3 Zoom Lens on my Nex 5N Camera?

A: Yes, I use them on that same lens.

Q: 8. I have a Nikon D3200 and a Sigma DC 18-250 lens, 1:3.5-6.3. Are these extension tubes compatible with this set up and if they are, are there any issues at all that I should be concerned with?

A: These extension tubes will be fully compatible with the D3200 and Sigma 18-250 lens. The extension tubes will allow you to focus closer than the set minimum focus distance of the lens. There will be some light loss when using extension tubes. Adding about 40% of the lens focal length will result in the loss of 1 f/stop. Additionally, focus to infinity will be lost.

Q: 9. I have a Nikon D300 and want to use my Nikon 50mm f/1.8D lens. Just starting to play with the idea of macro for fun. Will these work? What would be another lens size to add for these?

A: These will work. Autofocus and data transfer between lens and camera is maintained. As another answer mentioned, a 100mm lens would be a good one to try as well.

Q: 10. will this work with nikon d5500 body and Nikkor 70-300mm VR lens and the nikon 35mm prime lens af-s dx?

A: I use these extensions tubes with all lenses. I use them with a D5200 and a D750. There is an art to using these extension tubes. Play with them and have fun.
