photoreu Posted January 28, 2005 Share Posted January 28, 2005 Can someone please take a look at their 580ex and tell me if it does this: The AF assist light seems to have 3 lights in it, two on top, one on the bottom (at least that's how it looks). When mine lights up (when I press the shutter down halfway in a dark room) only the bottom and top right lights light up (when looking at the front of the flash). It still projects the big cross pattern on the wall but I'm not sure if one of the lights is not functioning, or used for something else? Or are there only supposed to be two lights? Am I just paranoid? It focuses fine, and fires fine.. but I just got it and want to make sure it's not broken. Please let me know! Camera it's on is an Elan 7e and 50mm f/1.8 lens.. if that makes any difference... Link to comment Share on other sites More sharing options...
steve_dunn2 Posted January 28, 2005 Share Posted January 28, 2005 <p>It's probably fine. If you look at a 420EX, it has two lights rather than three, and sometimes only one or the other lights up, and sometimes both light up. The reason is that each one projects a particular pattern and/or projects over a particular area. The flash and the body communicate to say which AF point(s) you're using and what types of lines they can detect, and the flash projects the appropriate pattern. I'd expect that the 580EX does something similar.</p> <p>Select only one point manually. If it's the center point, you'll probably see two of the three lights. If it's top or bottom, you'll probably only see one, and if it's one of the side ones, you'll probably only see the other one.</p> Link to comment Share on other sites More sharing options...
photoreu Posted January 28, 2005 Author Share Posted January 28, 2005 you are absolutely right... changed the focus points and different combinations light up... I hate being paranoid about new gear arriving broken and it had me worried.. thanks for the quick reply! :) now... time to go shoot some pics =D Link to comment Share on other sites More sharing options...
photoreu Posted January 28, 2005 Author Share Posted January 28, 2005 after playing with it some more looks like the bottom light emits the vertical lines, the top right emits the horizontal line, and the top left emits broader horizontal lines. If any of the 3 center focus points are used (top, center, and bottom) only the bottom (vertical line) is projected. If the focus points to the left or right are used the top two lights emit a broad horizontal coverage.. and if all 7 points are used you get the bottom and top right which makes the nice cross pattern on the wall.. :) Ok.. now I really <i>am</i> going to go shoot some pix! :) Link to comment Share on other sites More sharing options...
