<p>Thanks all! I guess I should change the lens now. Appreciate your help!</p>

<p>Here is the one with high ISO and shutter speed</p><div></div>

<p>Hi,<br /> I am very new to this shooting technique and wondering if there is any tips you guys can point out to help me gain experiences as below:<br /> I tried to shoot this object without flash but then, when I increase ISO and decrease shutter speed, the object still moves.<br /> When I increase the shutter speed and maintain the ISO then it seemes quite dark.<br /> I have seen some pic that people shoot in concert where the light is low and dont use flash, the object is freezed. Can anyone show me how?<br /> Thanks</p><div></div>

<p>Many thanks, Mark. This is more than what I need. Thanks a lot!</p>

 

<p>Thanks all. I've got what I need on page 89 of the manual. Thanks for the advices! :)</p>

<p>My manual is in Japanese.. & sadly I cant read those. Can anyone help me, please?</p>

<p>As I remember one of those ways allows you to choose AF point smaller than the normal AF Single point option and the other one triggers 4 other points around your AF Single point option.</p>

<p>I've just bought my new 7D and am still exploring its functions and wondering if anyone could help me with the AF point selection. As you would know there are 5 ways to work around with your AF point but I can only work with 3 ways ie. AF Auto, AF area & AF single point.<br>

The len I am using is EFS 18-200mm F3.5-5 IS. Is there anything to do with the lenses?</p>

<p>Thanks everyone for all of the answers! It's clear for me now.</p>

<p>Thanks! I suppose that a Cannon EF 70-200mm F2.8 L USM is a wide angle one then what should we call a Canon EF 85mm F1.8 USM?<br>

By the way, do you know what is "EF", "L", "USM" and "70-200mm"? Has anyone got some kind of glossary for these symbols?</p>

<p>Im just a newbie and this is very basic question could someone please advise what the differrences between those lens & when exactly I could use them!<br>

Many thanks.</p>
