andrei_lau1 Posted May 9, 2003 Share Posted May 9, 2003 After so many years I do hope that Canon can really improve on the flash hot shoe. I'm not talking about the electrical contacts, but the locking system. The use of screw to tighten is just a little old fashion and unreliable. On the one hand, you never know if the flash is tighten enough, or when you want to remove the flash, chances are you'll find the screw is too small to loosen it. If Canon can design a bayonet lens connector they should be able to find a way to improve on the hot shoe. I lost my flash just because I think it is locked and secure on the hotshoe but it wasn't. It fell and broke. Link to comment Share on other sites More sharing options...
NK Guy Posted May 10, 2003 Share Posted May 10, 2003 Which Canon camera and flash do you use? Most of them have locking pins which prevent what you describe from happening, though the earliest EOS models did not. Link to comment Share on other sites More sharing options...
eosdoc Posted May 10, 2003 Share Posted May 10, 2003 <a href=mailto:uce@ftc.gov></a>After so many years, Canon has really improved on the flash hotshoe by addinga retractable spring-loading pin locking system. This was introduced in 1989with the 430EZ and AFAIK all subsequent Canon Speedlites, as well as a somethird party flash units dedicated for EOS. See: <a href=http://www.kjsl.com/~dave/lockingpin.html>http://www.kjsl.com/~dave/lockingpin.html</a><P>So, I wonder what flash Andrei was using on his EOS 3? Perhaps it was aCanon flash more than 14 years old, or perhaps a third party flash without thehotshoe locking pin. Another reason to buy Canon for compatibility.

carl smith Posted May 10, 2003 Share Posted May 10, 2003 I've never had a problem with any screw down to tighten flash mounts. But i really crank em on there sometimes so I don't have a problem. As NK notes, when you screw down the ring on any modern Canon flash, a pin is lowered in to a hole that you can see on the shoe mount on the camera. You have to make a point of yanking the flash off to break it free. Link to comment Share on other sites More sharing options...
andrei_lau1 Posted May 10, 2003 Author Share Posted May 10, 2003 I use a 380Ex flash. I hope Canon may develop a bayonet type of flash that "clip" into position and push a button to release. This will be more reliable and convenient. Link to comment Share on other sites More sharing options...
eosdoc Posted May 10, 2003 Share Posted May 10, 2003 <a href=mailto:uce@ftc.gov></a> The 380EX has a hotshoe locking pin. Andrei, are you sure that the pin is not stuck in a retracted position? Or that you are turning the locking nut in the correct direction (shown by the arrow for "Lock")? Link to comment Share on other sites More sharing options...
