Summary: I have brought the Canon EF 24-105 mm F/4.0 L IS USM Lens from The Bigvalueinc on Nov 30 via ebay and received the product yesterday. Today, I tried it to take picture but I found the hard time to focus in AF. Suppose, this lens with USM should be able to focus very quick. I am wondering whether the product has problem or I didn't use it correctly? Hope the company can help me out from this.
Conclusion: i think this is a great lens if you know where it fails and don't need it for those uses. 1. no matter what some reviewers have claimed, this lens will not shoot all that well fully open at night or in low light. at best i'd say at f 4 this will give you fair to middling resolution. 2. very bad distorted perspective, like a big bowing, when shooting anything with noticeably straight lines.
Pros: Superior build quality
Cons: bowed perspective, fair at best sharpness fully wide open aperture
Summary: I'd read all of the great reviews of this lens and ordered one. I compared sharpness of the 24-105 to my Canon 17-85, 70-200 F2.8IS and the tamron 28-75. All three of these (YES EVEN THE 17-85), absolutely exceeded the 24-105 in contrast and sharpness. The 24-105 was not even close to the other three. All were shot at F5.6 at about 75-80mm. The 24-105 looked like a $100 lens compared to the other three! That copy is on it's way back to Amazon.
Summary: This can be had for as little as Ã‚Â£602 on the store that starts with A, yet its Ã‚Â£999 here and you have to factor in the cost of paying for it weekly too, so you are looking at over double the price.
Summary: Err 01 from the camera, indicating poor connection between lens and camera. This is a known problem with this lens and is a global issue. Just Google Err 01 Canon Lens and you will be surprised at what you see. Canon have been aware of the problem for a long time now but are unwilling to fix or even talk about the problem, only point you in the direction of a Canon repairer, and then you will be [$] + lighter in the wallet.
Summary: Ich habe in den letzten Tagen zwei Exemplare dieses Objektives in meinen Händen gehabt. Bei beiden war der linke Bereich des Bildes wesentlich unschärfer als der rechte Bereich (vor allem bei Offenblende sehr deutlich zu sehen). Angeblich ist dieses Problem sogar bei Canon bekannt, wird aber anscheinend vollkommen ignoriert. Ich habe langsam echt die Schnauze voll von von Canon.
