hey
I currently own a 18-55mm canon lens for my 20d its the one that comes with the cam. Anyways i find that some of the pics i take with lens come out a bit blurry but when i take pics with my 70-300mm is usm canon lens the pics are nice and clear. So can my 18-55mm produce shit pics because of the quality of the lens. If so what lenses could be recommened to use for normal pics around the 17-55mm lenses |

Pictures will usually come out sharper with a faster lense (lower F-stop #). Something like a f2.8. Are you shooting in RAW or jpeg. When shooting in RAW you will have to bring out the sharpness yourself.
Very difficult to know what you are talking about without seeing any pictures. Why not upload some?

A lens does affect quality, but the 18-55 is very capable of producing stunning results, as is the 70-300. The differences only become noticeable once you're capable of taking a great, quality photograph with both lenses...I suggest you try harder.

In photography... your glass just doesn't affect quality... it is everything.

glass is the key word.. some of those standard lenses (including the 18-55 i think) have some plastic elements.

Trav,
what sort of pics come out blurry?
If its photos of people moving fast (like sports), it could be the focus speed of the lens -- depending on the AF mode you use.
If its photos of people in dimly lit areas, it could be the maximum aperature is not wide enough, so the shutter speed is too slow. Remember that the rule for handholding a lens is shutter speed faster than 1/(focal lenth * crop factor)
Also remember that most lenses are not at thier best wide open or stopped down narrower than about f/11 or f/16 or thereabouts.
If you've got a ton of money, look at the EF-S 17-55 f/2.8 IS USM.
Otherwise, look at similar length lenses with fixed f/2.8 aperatures from Sigma and Tamron and (I think) Tokina
Note IIRC the 20D gives you better focusing with an f/2.8 or beter lens.

The lens is simply the most important factor in image quality. A "bad" camera with an excellent lens can get good pictures, but an excellent camera with a bad lens will always get rubbish.
Not quite as true as in the film days (when all is said and done, a film camera is simply a light-tight box, anything else is just garnish), but still very true. Seeing someone put a third-rate lens on a top-of-the-line camera is an instant sign of a tryhard suffering from Small Penis Syndrome.
(And yes, all sufferers of SPS do seem to be male!)
