Thank you so much - I will try that - and I do have a tripod and as I mentioned in last response I had plenty of light and a very low iso and shutter speed was not slow - so that is why the fuzzy bothered me.

wow! thanks for all the input - I am going to respond back, but need to go back and really read and understand all the input - thanks so much - this is great. I have two lenses I alternate between - generally - the 18-135mm f 3.5 and the 50 mm f1.8
when I was taking the shots that were not in great focus I had plenty of light - it was outside - maybe too much light - but definitely no shortage, my iso was very low
I will look at some more of the input and comment on that shortly!

I am new to this forum, but have been doing photography for around 25 years, but only in the last year have I decided to explore photography - learning how to do it right - and reading everything I can get my hands on and asking lots and lots of questions. The more I learn the more I realize how much I don't know! Anywho...I just purchased a Canon 7D - have used a Canon Rebel Tsi for a long time and just got my new one in March of this year. I have done many weddings and am just this past two years gotten into being paid - so I am now need to get a lot of help because it is more important than ever that my pictures be perfect. I would like to know if anyone knows the best way to take a large group and make sure everyone is in focus- is there a best setting to use to assure everyone comes out clear as far as focus points (is F22 the best aperature?) suggestions?! Thank you!
