Photos come out blurry on Av Mode on my 600D

While that book can be very useful, it appears that the OP also doesn't seem to understand how at least some of the basic controls of his camera work.

Yes, I understood that and acknowledged it by recognizing that the others posters were helpful in their responses, as well.

My experience is that a forum like this one isn't ideal in teaching basics. Trying to get in contact with someone who knows a bit more is more helpful. Forums like these are better at addressing particularities than general lack of knowledge.

It's almost certainly too slow a shutter speed that's causing blur due to camera shake and/or subject motion, as someone already noted. It also could be missed focus.

Get one of the guide books for your camerato help you become familiar with it quickly. Even with 30+ years experience, I always make a point of getting one of these books to help me get up to speed quickly with a new camera. I am sure many of those books are good, personally can recommend authors David Busch, Charlotte Lowry and Michael Guncheon from having read several books by each.

For a quick read to get a good understanding of more general photographic principles, applicable to any camera, "Understanding Exposure" by Bryan Petersonthat someone already suggested is highly recommended. Probably should be required reading before posting questions here!

You also have Auto ISO on... So with Av you have two automatic exposure modes running at the same time. I don't like to see that because it can be hard to predict what results you'll get. I'm a little surprised you are getting a really slow shutter speed, I would have expected Auto ISO to increase ISO and correct that.

Personally I don't use Auto ISO at all... I have no trouble setting the ISO myself. But if I were to use it, I'd only ever consider doing so in M (manual) exposure mode. Never in combination with the other auto exposure modes (Av, Tv and P).

He was shooting at f/9 and we don't know what the maximum in the auto ISO is set to. If he was shooting in low light without a flash that could do it. It would be helpful if the OP could articulate what his shutter speed and ISO were or at least give us an example. I don't recall if he indicated whether his subjects were static or moving. If they were moving in less than great light and with an f/9 aperture its almost certainly a shutter speed issue.

Hello everyone,

I have recently started using the Av setting on my Canon 600D, I played around a bit on the settings but now my photos come out blurry if I slightly shake the camera when taking.

Unless I'm taking a photo on a table it will just blur.

Can someone help me? Maybe change my Av settings. (I'm shooting in normal daylight)

Thanks

As others have said, you need to get your shutter speed right and a good starting point is to multiply your focal length x 1.6. For instance a 200mm lens x 1.6 gives a shutter speed of 320.

I should use my lens at 800 using that calculation but I can half it now and still get sharp photographs at 400 while hand holding my camera for birds in flight.

If all else fails -
