Q: 1. Hi, I am planning to buy Tamron Telephoto SP AF 180mm f/3.5 Di LD IF Macro Autofocus Lens for Canon EOS and wondering if this ring flash will fit and work on this lens or can you please specify what adaptor to use if I need one?

A: Yes, the Canon MR-14EX flash unit can be attached to the Tamron 180mm f3.5 macro lens using a special adapter ring made by Canon to fit on lenses with a 72mm sized filter diameter. See the link below for details on the required adapter ring: http://bhpho.to/JyRTj2

Q: 2. 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

Q: 3. Are there other ring adapters that I can use for other sized lenses than the macrolite adapter sizes? For example, a 62mm macro lens.

A: Yes there are. If you regard the Accessories tab on this flash's product link, under the header Other flash accessories you will see adapter ring options for 52mm, 58mm, 67mm, and 72mm. 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 below for the required adapter rings to connect it to your 62mm lens:http://bhpho.to/1frDLaahttp://bhpho.to/1lVIgRi

Q: 5. Can I use Yangnuo macro ring flash EX 14 RT -canon and Yangnuo remote flash triggers on Nikon 3300d, 5200d and 5300d? If yes, please let me know how to do it?

A: The Yongnuo YN-14EX-C Macro Ring Lite for Canon is technically for Canon. On a Nikon camera chances are it will fire but only in manual.Off camera you will need for the Nikon camera a manual wireless transmitter and a receiver for the YN-14EX-C. And again it will only work in manual.

Q: 6. 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.
