![]() The 11-blade iris creates circular out of focus highlights and a natural looking Bokeh. The built-in, 12-pin connector allows you to interface this lens with standard broadcast connectors. The lens mount supports electronic signal pass through, supporting EOS lens data management functions. The 18-200 C is, on average, sharper than the Canon EF-S 18-200mm IS Lens, Tamron 18-200mm Di II Lens and Tamron 18-270mm Di II VC PZD Lens. Lens: CarePAK PLUS (4YR) for 69.99 - BEST VALUE Lens: CarePAK PLUS (2YR) for 40.99. The zoom control includes a mini-LCD that displays zoom, focus, and iris setting.

The detachable drive unit, can be removed and reattached with the zoom in nay position, requiring no re-calibration. The lens features 180° of focus rotation for precise focus pulls and is marked in both feet and meters. The lens features a built-in 1.5x extender providing a 75 to 1500mm zoom range, capable of supporting 4K resolution. The lens features a 20x optical zoom and a focal length range of 50 to 1000mm with a maximum T stop of 5.0 at the wide end. With a detachable drive mechanism and support for rod attachment, it is designed to be equally at home whether being used by a solo camera operator or a full production team. The lens is designed for use on cinema cameras with Super 35 sized sensors and is suitable for 4K acquisition. The AF speed in contrast AF mode (aka LiveView) is very slow.The CINE-SERVO 50-1000mm T5.0-8.9 with EF mount from Canon is designed to combine the functionality and form factor of a broadcast, ENG-style-servo zoom lens with the optical precision of a cinema zoom. In real life situations this seems a little optimistic so make it a 3 stop advantage outside of lab conditions. The 18-135mm features an Optical Image Stabilizer for corrections up to 4-stops - at least according to Canon. There's no FTM (full-time manual focusing) though. However, the AF speed is generally fine, less so the accuracy at the wide end. The lens uses a conventional AF micro-motor (DC) rather than the typical Canon USM.

Fortunately Canon managed to keep a static front element so it's no problem to use polarizers. It is somewhat annoying that the focus ring rotates during AF operations. The zoom and focusing rings operate quite smooth although they don't scream "quality" here. The lens extends when zooming towards the longer focal lengths but there's no wobbling of the inner tubes even at the 135mm setting. The plastic quality is quite decent and the lens feels pretty "tight" in terms of build tolerances. The build quality of the Canon lens is slightly better compared to the typical low-end/"budget" class zoom lenses by Canon. In this scope the provided field-of-view is equivalent to 29-216mm on full format DSLRs. The EF-S naming refers to Short-backfocus design which is only compatible to APS-C EOS SLRs. Upon first, naive view it seems a bit brave to combine a 7.5x "budget" zoom lens with an 18mp DSLR - well, hopefully this is not too brave. The lens is available as part of a 7D "kit" or separately for about 400€/450US$. Starting with the release of the EOS 7D there's a new option in this market - the EF-S 18-135mm f/3.5-5.6 IS. Neither of the latter were overly impressive actually. Apart from the professional grade EF 35-350mm L and EF 28-300mm L IS there were also a couple of consumer zoom lenses-: the EF 28-200mm f/3.5-5.6 (full format) and, recently, the EF-S 18-200mm f/3.5-5.6 IS. Over the years we've seen a variety of "super"-zoom lenses made by Canon. Review by Klaus Schroiff, published October 2009
