Oh, stimmt. Habe gar nicht den Text dazu gelesen. Meine natürlich diese, die ich auch hab.

Das 18-55 ist kein Objektiv, das ist eine Scherbe ... ich mach damit nur auf Partys Bilder ... sonst ist das Ding nicht zu gebrauchen!
Selten so einen Quatsch gelesen.
There were a few moments when I considered not to publish the results due to "political correctness" because to date it was a quite absurd thought that such a cheap, or better "affordable", lens can perform this good and I'm sure that some will not believe the findings even though they're supported by the published field images. Anyway, the resolution capabilities of the Canon EF-S 18-55mm f/3.5-5.6 IS is nothing short of amazing. This is also surprising regarding the rather small changes in the optical design compared to the EF-S 18-55mm f/3.5-5.6 II. Still - the center resolution is excellent throughout the range even at wide-open aperture. Unlike most dedicated APS-C standard zoom lenses it is capable to keep a very good level even at the extreme corners of the image field. Its resolution characteristic is similar to the (much higher priced) EF-S 17-55mm f/2.8 USM IS at comparable aperture settings, quite a bit better than the EF-S 17-85mm f/4-5.6 USM IS and naturally vastly improved over its non-IS predecessor! Field curvature is not an issue. So is it a perfect lens then ? No, naturally not. It has its weaknesses - notably strong barrel distortions at 18mm and very high vignetting at 18mm @ f/3.5. Chromatic aberrations are well controlled at the extreme ends of the zoom range but quite pronounced around 28mm. In the field the lens struggles in contra light situations whereas the bokeh (out-of-focus blur) is pretty good within the limits of its depth-of-field capabilities. All-in-all the optical aspects are impressive and that's not only regarding the low price tag. The image stabilizer is quite efficient with a real world "gain" equivalent to about 3 f-stops. On the mechanical side things aren't so rosy. Canon changed the cosmetics of the lens and it certainly "looks" better now but the actual implementation has only been marginally improved compared to the EF-S 18-55mm f/3.5-5.6 II. The plastic quality (down to the lens mount) spoils the subjective quality perception quite a bit. The inner lens tube does still wobble significantly and accurate manual focusing remains next to impossible. However, the AF speed and accuracy is very decent and that's probably good enough for most users anyway. The Canon EF-S 18-55mm f/3.5-5.6 IS is certainly a value king, priced below 200€/US$, which is a good match for the resolution potential of the current generation of Canon's APS-C DSLRs.

The EF-S 18-55mm F3.5-5.6 looks destined to carry the flag as the kit lens sold with virtually every Canon dSLR over the next few years (and that counts as an awful lot of lenses), so it really needs to perform well in the face of some impressive competition. Fortunately for them, Canon have indeed upped the ante with this new lens; it's much better than its predecessor, especially in terms of sharpness in the corners and at wider apertures, and with reduced chromatic aberrations to boot. Indeed overall it's an extremely well-behaved little lens, with very few nasty surprises for the user, and a remarkably good image stabilisation unit; indeed Canon's main concern may ultimately become whether users have as much incentive to upgrade to more expensive optics as they did before.
Of course this is still fundamentally a relatively cheap kit lens, so all is not a bed of roses, and the test numbers don't quite tell the whole story. Local constrast is still lower than more expensive lenses, and flare can be a real problem, both likely predicated by reflections of stray light from the inside of the lens barrel, which is much less shielded than on more expensive lenses. The manual focus ring and lens hood are both nearly worse than useless, and while Canon aren't alone in cutting corners here, both Pentax and Olympus have shown that these simple features can be implemented well on a kit lens without bankrupting the company. So whilst this lens is indeed very good, if not exceptional for the price, and certainly very much better than its unstabilized predecessor, surprisingly enough it still can't quite match the more expensive lenses in the range.
In summary, this lens is a very welcome addition to Canon's range, and gives new dSLR owners a level of optical quality in the basic kit lens which was previously lacking; the addition of IS also goes a long way to increasing its flexibility. It makes an ideal lightweight general purpose-starter lens, and as such can only be recommended.

Wäre mal jm. so nett und ein Bild von seiner Cam mit aufgesetzem Objektiv hier reinzustellen ?
Hat der Eine oder Andere von Euch Probleme an der Naheinstellgrenze richtig zu fokusieren?
Jou, ich habe dabei auch Probleme! Habe das Thema hier auch schonmal angesprochen. Eine richtige Antwort habe ich nicht erhalten, wobei ich dabei durchgehört habe, dass es normal sei, wenn man sich da schwer tut. Abhilfe schafft da in der Tat unter anderem live-view. Aber erzähl der 30D mal was davon. ;-) Also muss man wohl damit leben.
Kit-Objektiv ist kein so passender Vergleich, da 18mm doch was anderes sind, als 11-16mm...
@all
Würde es denn Sinn machen es justieren zu lassen? ...möchte ich eigentlich nicht.
Ich bin mir momentan auch nicht so sicher ob der Fehler immer auftritt. Denke eher, dass das ein Glücksspiel ist ob der Fokus richtig sitzt. Werde mal bei etwas schönerem Wetter noch ein paar Bilder machen. Dann sind die Lichtverhältnisse besser...
die gute schärfe bei offenblende ist wohl der größte vorteil, z.b.Hat jemand ein paar Bilder für mich bei schlechten Licht und 2.8er Blende?
