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

Related Questions and Answers

Q: 1. Does the auto focus work with AF-S lenses?

A: Yes. But is is much better to use manual focus with focus assist in viewfinder. Using manual focus gives the photographer much better control over focus point as depth of field becomes critical with extension tubes.

Q: 2. I have a 24-70 and a 70-200 (both Sigmas), will this extension tube set work with my lenses? I need to get some real detail shots of rings...aka macro.

A: If the mounts are canon mounts they will work, but you may lose the auto focus capability . Check the specs carefully or write kendo.

Q: 3. How close in quality and build are these to the Canon branded tubes?

A: I cannot offer a precise answer to your question as I have no experience with the Canon branded extension tubes.I can tell you that the Kenko tubes have a very solid build feel to them.The bodies are made of sturdy plastic with metal mounting flanges with electrical pass through contacts.There is no glass, no glass or coating differences to consider, are just tubes with air space. A few things to consider about extension tube use if you haven't yet;The longer the focal length of the lens, the less the magnification. The math; extension tube length divided by lens focal length = magnification increase.This increase gets added to the lens' native magnification. As the minimum focus distance is decreased, depth of field decreases dramatically, essentially to what is considered razor thin.I've found it too difficult to hold focus while hand held.Good is a determined and methodical set up on a tripod.If shooting a subject that is essentially two dimensional and therefore in a single plane, you'll want the camera perfectly square to the subject (set with a mirror) if you want the whole subject in focus with a single frame. Such shots will get boring quickly. For 3D subjects as a flower, only a very thin slice of the image will be in focus, sometimes that'll be exactly what you want. Stopping down the lens' aperture (larger f/number) always increases depth of field.If you want the entirety of a subject as a flower sharply in focus, you pretty much have to focus stack several frames together in post. At maximum magnification of a full set of tubes on a short focal length lens, lighting the subject is another issue to be solved, the lens will be so close to the subject as to block most light. Bottom line, yes, I'd buy them again, yes, I recommend them 100% with the condition that a potential purchaser has a good idea about what can be expected of them.I've found they do 100% of what is expected, they do nothing not expected.10 on the 1 to 10 scale.

Q: 4. Will this work with d3400 ? Thanks

A: My set of Kenko extension tubes works very well with my Nikon D3400. Depending on which lens I use, I sometimes prefer auto focusing and sometime prefer manual focusing.Have fun discovering which technique works best for you !

Q: 5. Leica TL 2 compatible lenses

A: I used it on my canon but didn't find it much useful. Hence bought Macro lenses.

Q: 6. Will these extension tubes work with a D750 and a SIGMA 50mm f/1.4 Art lens ?

A: Yes, the Kenko Auto Extension Tube Set DG for Nikon Lens would be compatible for use with the Sigma 50mm f/1.4 DG HSM Art Lens for Nikon F on all Nikon DSLR cameras, including the Nikon D750 DSLR camera.

Q: 7. Can I get greater than 1:1 reproduction with a Canon 50mm 1.8 with this set?

A: No, you will not get greater than 1:1 reproduction when using extension tubes.

Q: 8. Would these work with the Leica TL or TL2?

A: I dont believe so. I am not familiar with Leica. Leica lenses for the Panasonic micro 4/3rds cameras would work with these ext tubes. TL and TL2 are APS-C so I dont believe so.

Q: 9. Does this Extension Tube work for FE-mount (Full Frame) lens on Sony A7/R without the need for any cropping?

A: We have not had the ability to test this out yet, but there is a good chance that you will need to crop when using the Kenko Auto Extension Tube Set DG for Sony E-Mount Lenses with the full frame Sony A7 and A7R, as this extension tube set is designed for APS-C format E-mount cameras.

Q: 10. What ratio do the individual tubes give with a standard 50 lens.. As in 1:2, 1:1, etc??

A: All figures are based on a reading at 0.5 meters:12mm = 0.3520mm = 0.5136mm = 0.83Contact me through a href= http://Kenkotokinausa.com target= _blank Kenkotokinausa.com/a and I can supply you with a complete instruction sheet that will answer all of your questions.
