Q: 2. 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: 5. WILL THESE EXTENSION TUBES WORK WITH A NIKON D500?

Q: 6. Why is there a limit to shoot at f/5.6 or f/8 and not f/22, f/16 or f/32? I use a Canon EOS 70D with Canon EF-S 17-55mm f/2.8 IS USM Lens and Canon EF 70-200mm f/2.8L IS II USM Lens. I am planing to buy the Bolt VM-160 LED Macro Ring Light. Will this help or what, please answer in detail.

A: Using extension tubes reduces the amount of light entering the camera, requiring wider and wider apertures as the extension gets longer. HOWEVER, macro photographers typically use flash, thereby permitting the use of narrower apertures. In fact, depth of field is so shallow in macro photography that macro photographers do everything they can to shoot in the range of f.16. Extension tubes decrease not only light, but also depth of field, making the use of narrower apertures even more important.The Ugly Hedge Hog photography forum (strange name!) has an excellent macro photography section where plenty of good advice is freely offered. There is one thread devoted to photos of member's macro set ups, where you can get a good idea of types of flash used. You will likely be surprised that NONE of the good photographers there use a ring flash. Their experience is that ring flashes produce flat lighting. They almost all have do-it-yourself flash set ups that produce much better results.Good luck! Oh . . . the Kinko extension tubes work very well.

Q: 7. Will this bracket work with the nikon D200 and SB900 flash unit?

A: No, it would not. The RPS Lighting RS-0420/S RPS TTL Digital Flash Bracket Kit for Sony Alpha DSLRs listed above is designed for use with Sony Alpha DSLR cameras that use Sony's Auto-Lock hot shoe, not Nikon DSLR cameras. As such, the above option would not work with the Nikon D200 DSLR camera. As the Nikon D200 uses the Nikon 10-pin remote terminal, you would need the RPS Lighting RPS Digital Flash Bracket Kit - Includes Bracket, Off-Camera Cord & Cable Release - for Nikon Pro SLR Cameras, B&H # RPFBN, for your needs.
