Originally posted by ivanvernon I am studying how to put together this same system for my 645D/645Z set of cameras. I have tried to look up each component on eBay, and actually I am a little surprised that the costs seem pretty reasonable. I hate to bother you with ignorant question, but hope you will help me.
1. What is the exact name of the RotaCam strobe frame, and where can it be purchased?
2. I think I have all the components figured out except for one item, and that is the component that fits directly on top of your 645D in the hot shoe. I am thinking that the Cactus V6II is a two-part set, with one part serving as the base for the off-camera flash unit and the other part fitting into the on-camera hot shoe. Then the second part above the hot shoe would be the Neewer FT-16 16-channel Trigger Transmitter Receiver.
3. I am assuming that you need a base for each off-camera flash unit, meaning one base for each flash unit, but only one unit in the camera hot shoe.
4. Are there any cables, fasteners, or other connector elements needed to assemble the system?
Sorry to sound so obtuse, but hoping you can help.
Thank you very much.
1. Mamiya Rotacam flash bracket for 645af. These are not sold any longer but can be found on ebay from time to time for between $100 - $150. They are very sturdy and lightweight and should last a lifetime of rugged use.
2. The Cactus V6 II sits directly on top of the camera, between the camera and the Neewer FT-16s Transmitter.
3. To fire the flash, in my case it's the Neewer 850tt with the Neewer FT-16s Receiver attached.
4. Only 1 Cactus V6 II Transceiver is required with the setup I used In the picture above.
I bought the Neewer FT-16s Transmitter/receiver combo from Amazon for about $17, the Godox version sells for over $30. I've used the Neewer brand of these for approximately 2 years on 4 of my Neewer 850TT flashes without ever encountering any firing issues so I thought I'd mention that in case you would like to try these and would want to save a few $$$. I love the lithium batteries in those flashes with their short recycle times, plus they seem to last forever before needing recharged.
