Glenn McCreery Posted May 14, 2015 Share Posted May 14, 2015 <p>I can't answer your question directly, but a new ultra-high speed flash is entering the market. An inventor, Matt Kane, from Bristol, UK, has developed an LED based flash that promises a sub-microsecond duration. see https://www.vela.io/ for more information. Because of the extremely short flash duration, the guide number is low, and therefore ambient light may overwhelm the flash unless used in a dark room or at night. So, using it for hummingbird photography may be problematic.</p> Link to comment Share on other sites More sharing options...

greg_scott Posted January 18, 2017 Share Posted January 18, 2017 <p>I have an Olsen Ultra flash in excellent condition. I'm selling only because of poor health.<br> Interested people should email me at home@gregscott.com<br> It is powerful, has four flash heads, and is in excellent condition considering that it was made maybe 20 years ago.<br> It has new capacitors (reworked circuit board)<br> It is suitable for photographing raptors in flight on the flight path to their nest, for example. I used it mostly for hummingbirds, where it was pretty much overkill.<br> <img src="http://gregscott.com/hummingbird_studio/hs200_med.jpg" alt="" width="966" height="750" /></p> Link to comment Share on other sites More sharing options...
