Q: 1. My Question is regarding the effective range of 8.8 feet to 16 feet at f2.8 ISO100... If its a Macro photography flash shouldnt it be effective INCHES away? ANd NOT 8.8 feet away?My 600 ex rt is good at these ranges.

A: I have used it both ways. From about 2 inches with the Canon 100mm macro lens, as well as up to 15 ft away. At the longer distances, the nice this is you get portraits with no shadows.However, beware, though it is a great flash unit, Canon made the lens attachment thread only 67mm, which highly limits what lenses you can use it on. In other words, make your homework and make sure the flash will be capable of attaching to the lenses you are going to use, else look for alternatives that have a larger thread mount.

Q: 2. Is this compatible with the Canon R5 with the use of a filter adapter?

A: Yes, you can adapt the Canon MR-14EX II Macro Ring Lite to other lenses via the use of a step-up/down ring with a Macrolite adapter. Please be aware that with some lenses this might cause a slight vignetting, but apart from that, usage should be relatively seamless.

Q: 3. Is there a mode to set the flash to auto-off after a period of non-use to save batteries?

A: The MR-14EX II can be set to auto-off using the Custom Functions feature C.Fn.01. Please refer to page 61 in the manual for step by step instructions: http://bit.ly/2caYHdW

Q: 5. Is this compatible with the Canon EF-S 35 f/2.8 Macro IS STM lens?

Item 1, any of the Canon Macrolite adapters, like this one: https://bhpho.to/34tA33y Item 2, a stepup ring from 49mm to the same size as the Macrolite adapter: https://bhpho.to/3yQInZe
