Message: <blockquote data-quote="bartolli" data-source="post: 1240651" data-attributes="member: 66963">For several months now I have been playing with the various settings on my canon a510 and generally failing quite miserably when it comes to focussing thro my bresser scope.I use a swingout adapter, scope at min zoom (20x) and just enough camera zoom to get rid of vignetting. I locate the target, focus the scope and swing the camera back to take pics with a cable release.I generally shoot at ISO 400, but use 200 if light permits. Usually I have the camera in aperture priority mode and use centre spot exposure (although I have also played witrh centre-weighted).For focussing I originally used the option where the camera picks one of nine central squares, but then changed to spot focus in the central square, yesterday I tried the 9 square option again. (There is probably a technical term for this!)I have tried the above with the camera in macro and landscape modes, I have tried manual focus with the setting at infinity.I have also tried manual focus, but find it virtually impossible to tell from the LCD screen whether the focus is ok.I have tried pushing the release half-way and then refocussing the scope but again this relies on the LCD screen to see if the pic is in focus.Occassionally, using any of the above settings, I get one or two shots which are in reasonable focus. None of the above settings seem to have any better success rate than the others.The only way I have found to improve the situation is to have no zoom at all on the camera. The photos are then quite well focussed but I obviously end up with BIG vignetting. I can crop/resize these but with 3.2mp this is a bit limited.So, what am I doing wrong with the focussing? Any suggestions whatsoever greatly appreciated as I am getting a bit frustrated, especially when I see all the beautiful photos on this site!! Note that I don't really expect to take awesome photos, I just want some that are reasonably well focussed!Thanks for reading this far! The attached pic has just been cropped to get the size within limits.</blockquote>
