    I'm shocked your unhappy with sharpness of your 18-50 macro, perhaps your not post processing your images?

    Out of the camera they will not be very "sharp" viewed at 100%.

    Personally, I like the f4L more. I'm going to buy a f4L IS at some point and just use a 1.4tc on it if I need reach.

    that is a very sharp lens, not just sharp for it's price range but sharp full stop. the only place its a little softer is wide open at 2.8 but this is a common issue with any lens in that shot wide open they are always softer than their "sweet spot".

    i gotta say that it's one of the sharpest non-pro lens' i have used from either system. if you are not happy with sharpness from that lens, you are going to be disappointed with a heck of alot of other lens'. either the lens is faulty, your camera settings are off or you aren't using it right.

    Here are some examples. All are at 300 mm. I didn't bother to do 100% crops, so bear in mind these are the softer resized-for-the-web versions. I love this lens.

    I agree with Rooz. The 18-50 is not the sharpest lens money can buy, for sure. But for its sort, it really is rather sharp and a very nice lens.

    Can you show us some examples of why you find it not a good lens?

    A question for Coldrain...

    From what I have read, all canon lenses that feature Ultrasonic USM Motor allow FTM (Full Time Manual Focus) and feature non rotating front element, than how come the 70-300IS inspite of having USM does not allow FTM and has a rotating front

    I rest my case. I am buying it. I sent an e-mail to Adorama to see if they can check for me the serial number of the lens, since according to Canon, some suck at 300mm in vertical orientation! I think this was the reason I read here and there that its performance is not good at 300mm.

    The performance of just about any 70-300 or 75-300 lens is not that good at 300mm, this Canon 70-300 IS is just the exception.
    I hope you will be happy with your new lens...

    Viky, there are two kinds of USM motors. A small one and a bigger ring one. The 70-300 IS has the smaller version. And the lens design/construction makes that this lens, for this weight and performance, has a rotating front element. Just a decision of the lens designer... they placed importance on other factors (and that shows in the very good performace of the lens). Lens design is also about making compromises... And with this lens, the compromises were in the build, not in the optics.
