Q: 1. What is the outside diameter of these lights?

A: The dimensions of Vibesta Peragos Disk 304P Daylight LED Light are 6.3 x 2.2" / 16 x 5.5 cm.

Q: 2. I know extension tubes make the widest focal length zoom in because it spaces it away from the lens.By what factor with the Extension Tube 12 increase the focal length by?Ex - Factor of 1.5 making a 50mm now a 75mm.Help!

A: The Extension Tube EF 12 II wouldnt have an effect on the angle of view or focal length of the lens. Extension tubes will simply decrease the minimum focus distance of the lens, allowing you to focus closer to a subject. So, a 50mm lens would remain a 50mm lens, and would still have the same angle of view.

Q: 3. Is it compatible with third party lenses? For example Tamron or Sigma lenses?

A: I use this often with a Sigma 150-600mm Contemporary Lens to shoot dragonflies and it works fine. As others have mentioned infinity becomes a lot closer. A gent at a local pond was taken aback when I told him I could not take a picture of the snapping turtle on the beaver lodge because it was too far away. I took off the EF 25 II, got the shot of the turtle, put it back on and got back to my dragonfly hunting.

Q: 4. Will this add some vignetting to my rokinon 8mm fisheye?

A: Hi--extension tubes can cause vignetting, but more commonly with telephoto lenses than with wide-angle lens. If there is vignetting, it should be slight.

Q: 5. It looks like this has metal mounts, what is the body made of ?

A: The body of the mount is made of a magnesium carbonate material, to the eye it will look similar to plastic but it has a metallic feel to it.

Q: 6. Can I use this with the EOS R and the EF 100mm 2.8? As the lense is already adapted to the camera.

A: Yes.

Q: 7. Is the Canon EF 25 II Extension Tube compatible with my Canon 17-55 mm F/2.8 IS USM lens? Will it give me the ability to use auto focus and image stabilization with this extension tube or will I lose that ability?

A: This extension tube has full Auto focus capabilities; that's what all the pins are for they allow communication between your camera and lens. The image stabilization isn't depended on the extension tube. It's set separately on the lens. I am not sure why you want to use an extension tube on a wide-angle lens. Extension Tubes are usually used on telephoto lenses, allowing them to focus closer, and on macro lenses to gain some extra magnification. The whole point of an extension tube is to decrease the minimum focusing distance of a lens, and gain a little more magnification. A wide-angle lens inherently has a close focusing distance already, and normally you are shooting wide, and don't need any magnification, because if 35 mm is close enough, just zoom in to 55 mm. You have both abilities, but there really not usable on your lens. If you had a 600 mm lens, then this extension tube would be a good accessory to have.

Q: 8. Any comment on how well this works? Thanks.

A: This tube works very well, no issues.

Q: 9. How is the flash sync feature used? Does it require a sync cord or hot shoe? does it work with most dslrs or mirrorless cameras without additional accessories?

A: Both the 304P & 304B offer flash sync by a wired cable or wirelessly with an optional RTX-1 wireless router by means of an ArtNet-compatible app. The flash sync function is not through any sort of hot shoe as this light uses a 1/4"-20 mount or can mount in a cold shoe. Please note that the 305C does not have a port for attaching a cable, but can be controlled wirelessly with the previously mentioned router and app.

Q: 10. If I added all three to my 24-70mm, what would the focal length become?

A: There isn't an exact way to measure this, however, you may gain a greater understanding about using auto extension tubes for macro photography with this article: http://bhpho.to/1FlRZru
