Title: 7D and maxxum 3500xi flash
Post by: Anonymous on October 31, 2005, 07:13:05 PM
I bought my Maxxum 7D about two weeks ago. It works good, but not with my maxxum 3500xi flash. All my shots are totally over exposed, littery I get a blank (white) screen. Also, the wireless, althoug it shows on, it does not work. Obviosly the flash is not compatible.  With some major adjusments I got better resoults but nothing for practical use. Is there any way I can make this work or is my flash scrap?

Not that I know of. I have the same flash, and it doesn't work at all with the 7D (http://www.dynaxdigital.com/viewtopic.php?p=343#343). The measurement systems are incompatible (flash control with film and digital are completely different), so the flash just fires full-burst all the time (which usually is way too much). The only way I know of to use it at all is to set the camera in M mode, and lower ISO and aperture until you get a decent exposure.

Guest: I have a 5200i flash that is 15 years old. It will fire on the 7D but can effectively only be used on M mode. This is no good for "fast action" images where you must ave fast exposure controls. However, if you have time it works reasonably well. Two weeks ago, I used the 5200i on the 7D at an anniversary party. For controlled shooting it was fine. The speed was set at 1/60 or 1/125 and all I had to do was change the aperture between 5.6 and 11 (as I recall) depending on distance. I took lots of shots of people speaking from a podium, so distances were within a narrow range. I had time to take several images anyway, so could make minor adjustments in aperture to get the correct exposures.

I used the 5200i two weeks ago to take closeup "studio" shots of barley seeds. Using the flash's exposure ratio controller and a white foam diffuser, it worked well.

My 7D came with a 2500 flash and it is useless. Why they shipped it with the camera I'll never know. I am trying to get a credit from the Canadian agent for KM. If they cooperate, I will perhaps get a new digital compatible 3600 flash.
