Q: 5. Can I use this with the Tamron 90mm macro lens.

A: You can use the Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD Lens for Canon EF with the Canon MR-14EX II Macro Ring Lite with your Canon DSLR camera. Remember that the Tamron uses 62mm filter thread, so to adapt it to a lens with a 62mm filter thread size, you would need to purchase the 67mm adapter ring for the flash and then use a 62-67mm step-up ring to connect to that. See the two links shown below for the required adapter rings to connect it to your 62mm lens: http://bhpho.to/1frDLaa and http://bhpho.to/1lVIgRi

Q: 8. I have a 100mm non-is Canon macro lens, with Canon hood. Will I need to remove the hood to use this flash?

A: yes

Q: 9. 1) What is the range of flash duration for this product? I have an MR-14EX, and it doesn't always freeze motion. Any suggestions?2) This flash seems to fire milliseconds before the shutter opens, which can give some live subjects enough time to react--some can fly right out of frame before the shutter opens. Is there any way I can get around that?

A: The MR-14EX may not freeze motion all the time because it is intended for close up subjects, where there is not a lot of motion to begin with. To avoid the pre-flash, you could use manual mode. Keep in mind, however, that manual mode will not allow for TTL use of the flash. Another solution to this issue would be to use a ring light, such as the Digi-Slave L Ring 3200D, which will provide a continuous light source and potentially be able to deter the subjects from moving when the flash fires off: http://bhpho.to/1gdjkPn
