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. I purchased these from you already but have not used them yet. I am using both a Canon 7D and a Canon 1DX with the Canon EF 100mm f/2.8L Macro IS USM Lens. How can I use these so that autofocus function is retained? Thank you.

A: The first thing to understand about macro photography, is using AF (when possible) is a convenience that will become more of a hindrance in the long run. The benefit of extension tubes, and also just a macro lens such as the Canon 100mm goes is that they allow for much closer focusing than with other common lenses. They get so close that the AF sensors in most cases are not able to decide on what the focus point is, and end up causing the camera's focusing sensors to hunt back and forth never coming into focus. The majority of macro photographers out there end up shooting in manual focus mode, and the better approach is to physically move the camera closer and further from the subject in small increments and manually tune the focusing till you get what you want.To answer your question directly, the Canon 100mm f2.8 L IS USM Macro lens has a minimum focusing distance of 1 foot (distance from sensor plane to the subject). Using the tubes will decrease this distance. Youll ultimately have to experiment with each tube and the lens to see what the tolerance of autofocusability will be.

Q: 2. 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: 3. Id like to use this with a 50mm f 1.8 E series lens mounted on a D7100, would I have to change the non cpu information in the camera? and if so how would you calculate it?

A: I've used it on a D610 to shoot RAW's of color transparencies, and did not change anything significant. Everything looked good.

Q: 4. I just purchased the MCES-16 and I am finding that my X-T1 camera will not focus at all with the XF18-55mm lens. Am I missing a setting or something or is the tube defective?

A: When using the Fujifilm MCEX-16 16mm Extension Tube for Fujifilm X-Mount, you will lose infinity focus, but you will gain the ability to use the lens as a psuedo-macro lens to focus closer than the lens' listed minimum focus distance. However, do note that when focusing within close focusing distances, the camera would require contrast and lighting to be able to focus on your subject. Many people find it is easier to focus manually when using an extension tube. Autofocus may be achieved if it is bright enough or there is enough contrast on your subject, but it may hunt-and-peck back-and-forth trying to achieve focus, so focusing manually may be best in certain situations.

Q: 5. I have 16mm, 27mm, 35mm and 18-55mm. Should I buy this MCEX-11 11mm or MCEX-16? Which lens would benefit the most from these 2 tubes for macro photography?

A: You can decide by referring to the following table from Fujifilm. B&H won't let me include a hyperlink, so... Go to the Fujifilm Web site, click on products, digital cameras, accessories, lens (Lens Accessories). There is a link to a PDF entitled Magnification of the Macro Extension Tube. The document is a table for all Fujifilm lens and both extension tubes.

Q: 6. I already owned a 16 which can focus quite close. I also own a 23,35,56 & 55-200 lens. Do I need to buy an extension tube to actually do macro work? Would you recommend the 11 or 16 mm extension tube?

A: I also own a 16mm lens, and at closest focus, the subject is only about 2 1/2 from the front of the lens - that's often too close to be able to adequately light your subject (and too close for comfort to photograph a bee on a flower!). I bought the MCEX-16 but not the MCEX-11 because it gives me the range of magnification that I need with my 27mm, 55-200mm and 100-400mm lenses. I use it with my 27mm lens, for, among other things, copying old 35mm slides as it almost exactly covers the 35mm 1 x1 1/2 size. I've used it with my 100-400mm at 400mm to photograph frogs in a pond, giving me extreme closeups at a distance that is much closer than the lens normally focuses. Yes, it not equivalent to a true macro lens since you won't be able to focus at things further away, but that's not relevant when you're taking close up photographs. The comment about not accepted as a true macro in competitions is wrong - macro photography is about photographing things close up, not about the equipment you use to take the photographs - you can use a true macro lens, a lens with an extension tube, or a lens with closeup filters (which I also have and have gotten some great images - the reason I bought the MCEX-16 is that my close-up filters fit only on my 27mm lens and i wanted macro capability with my other lenses as well)

Q: 7. I know these tubes have metal mounts, but is the body/barrel metal or plastic?

A: The barrel is plastic, but seems very sturdy.

Q: 8. What is the diameter of the actual tubes threading to each other; like 60mm filter thread?

A: The outer diameter of the tubes is 63 mm and the diameter of the threads is 59-60mm.

Q: 9. Leica TL 2 compatible lenses

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

Q: 10. Does the OIS on my 18-55mm still work with the tube installed?

A: Yes.
