  • The last part of the commander's control preflash is the signal for the remotes to fire and that must occur when the shutter is open.  It will register in the captured image. Unless your are ...
  • I can't answer your question but I too would expect the "pilot" button to test fire everything that you have enabled. That's what my YN 560TX transmitter's "test" button does.  I assume you ...
  • Well you can under limited conditions.  The "S2" optical mode of my YN 560III units successfully ignores all the CLS control preflashes and fires correctly for the actual exposure.  The ...
  • The SB-600 has a "smart" optical sensor looking for Nikon's wireless commander signals when set to remote mode.  It won't function as a simple (aka dumb) optical trigger.  For that you have to add ...
  • Your proposed setup is unclear. You perhaps may be attempting to combine optical Canon eTTL triggering with RF triggering of the studio strobes. I suspect a Canon eTTL optical master flash may work ...
  • Replied in Timing issue
    At one time I considered the Strato II triggers and from what I've read on the gear guide on flashhavoc.com I believe you need two pair of triggers on different channels for this use. One pair for ...
  • I tried shorting the center pin on my YN 560 mkIII's hot-shoe and found it is dead in all but the camera top mode.  Optical S1/S2 and RF modes would not accept a signal from the hot-shoe.  I don't ...
  • I believe the hot-shoe is always live on Nikons and only the pop-up can be turned off via camera settings and then only for scene modes.  In PSAM the pop-up is turned on/off by raising/lowering it. ...
  • Replied in Leaf shutters
    Basically a leaf shutter needs to be located at a specific point in the optical path which is generally within the lens between the elements. With an interchangeable lens camera this means a ...
  • Like ScratchDisk I don't know of any radio TTL wireless for Fuji. Here is a dpr thread about it . I'm also fairly certain there is no optical TTL wireless either at least as of Feb. 2014. Another ...
  • Any speedlight compatible with Canon's IR light based TTL wireless flash system (that's what your Canon version YN 568exII uses as a master flash) has its optical triggering built in allowing it ...
  • I have been using shutter speeds to get a rough approximation for the upper and lower bounds on the shutter curtain velocity. The fastest speed that will fully sync divided into the sensor height ...
  • Perhaps I can help. I have experimented with my 2 pair of YongNuo RF-603 mkII (Nikon version) triggers and made extensive notes on their operation because of the poor YN instructions. When I say ...
  • As many have suggested your lens probably doesn't have the EF/EF-s mount of current Canon DSLRs. You have just entered the Canon Zone , a strange place where reality is suspended, old and new ...
  • You're supposed to see "distance" perspective in action. Here are a couple of link explaining what Tom_N has correctly identified as the take away from the exercise. http://imaging.nikon.com/lineup ...
  • The Cactus V6 makes the most sense for someone who already has several TTL flashes, even mixed brands, because it allows them to now be used together in manual mode with remote power adjustment. ...
  • Replied in Canon memories
    This thread brought back a lot of Canon memories and yes, some of the old mechanical SLR dinosaurs still work. At last check only 3 of my Canon manual focus Canon SLR collection (9 total) don't ...
  • Since YongNuo doesn't offer a TTL model for Sony their manual only YN-560 mkIII or mkIV models are the obvious and inexpensive choice. These speedlight have built in RF and you can remotely adjust ...
  • Don't laugh, I'm serious. A " Thumb Screw " is the name of a threaded fastener with an easy to grip head for hand tightening. A well stocked hardware store may have something that will work or ...
  • Like I said here for use on camera I recommend a TTL flash especially if it's your 1st flash. If you are comfortable with manual flash (I suspect not-see explanation below) then sure, the YN-560 ...
