How did you set the ISO to be 800 in auto exposure mode? I have a 550d and in auto expures mode the (in the low light) the ISO goes up to 3200 or 6400 making it really grainy

@MediaBrighton How do you know it went to 800? If your lens' aperture is higher then that makes sense that your ISO goes up more to try and capture a well exposed shot. When you shoot try setting your aperture to it's lowest setting, turn auto exposure off, and play around with the shutter and ISO until you get a nice and exposed shot..

I'm guessing this is the f4-5.6 Sigma 10-20?

[TimsTechBlog]

@RobDH1 Yep, that's the one.

@TimsTechBlog Thanks...but I think you miss understood my question..I was asking you how you set your iso at 800 when operating in auto exposure mode...as it says in your video description above.....it says: ISO: 800
