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: 5. 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: 6. What is the effective aperture loss when using the tubes?

A: The Kenko Auto Extension Tube Set DG for Canon EOS Lenses does have light loss. it does depend on the lens. The formula for that is, Ef = Effective f-value (that is what you get after adding extension tubes or bellows) If = Indicated f-value (that is shown on your lens or display, the one that is set on the lens) F = Focal length of the lens Ex = Extension (total length of the extension tube or bellows) The formula is: Ef = If x (F + Ex)/F

Q: 7. Is there a way to use EF tubes with Canon R6, RF lens, and EF-RF adapter?

A: No, there is no way to use the Kenko Auto Extension Tube Set DG for Canon EOS Lenses with an RF lens on the R6 Mk II Mirrorless Camera.

Q: 8. Has anyone used these extension tubes with Nikon 300 mm f 4 or 600 mm f4 VR lenses?

A: Most use extension tubes with shorter lenses. Usually lenses around 100mm or so at the most.One issue is that the focus will be critical in general and very difficult to focus with such long focal length lenses.

Q: 9. does this item work without vignetting on an a7r?

A: I use on Sony A99V it OK.

Q: 10. Do both the Kenko and Vello extension tubes for the Nikon support the Nikon D-300?

A: Yes, they are both compatible with the Nikon D-300.
