i am a huge newbie in SLR and photography, i have a canon EOS 350D (may be it was called Canon EOS Rebel XT in US) and had always used it in full newbie mode letting the camera in full automatic (the wheel mode is on green square)
i just have received a brand new Tamron 18-270mm F-3.5-6.3 Di II VC PZD and try it a bit, with the same "auto green square mode"
and i'm quite puzzled, it always triggers the flash, while i am outside with a very shiny/sunny day.
and it seems to me that it most often appears when using it at 270 mm
please, have you any idea why it is doing so ?
i first thought, that it was due to fact that this lens is heavier and my way of handling the camera with this lens, my fingers were masking the cell that automatically decide to trigger the flash or not, but it is not only that. I have not clue at all of why the flash always appears and flash
thank you for any help provided
(and please apologize my approximate english)
EDIT : i can, of course, set the newbie mode with no flash allowed and in this case it will not trigger, but i am bit confused that the camera can not decide anymore in "full auto mode" ("green square") that it needs flash or no... Having the flash always on is quite disturbing and will probably decrease battery autonomy a lot
