Canon EF-S 18-200mm lens

The Canon EF-S 18-200mm lens is a superzoom lens, manufactured by Canon. It is the kit lens for the Canon EOS 50D digital camera, and supplants the previous EF-S 17-85mm, in Canon's product line-up, losing 1mm off the wide end, but offering a roughly 2.5x longer telephoto end. While Canon has produced superzooms for the full frame EF mount, they function only as normal length to long telephoto lenses on cameras equipped with APS-C sensors. This is the first EF-S lens made by Canon to offer both wide-angle and telephoto shooting range in the same package. Other manufacturers, including Sigma and Tamron have had similar lenses available for EF-S cameras for some time; however, their lenses generally only work at f/6.3 when fully zoomed in, which can make autofocusing unreliable (Canon's APS-C cameras are only designed to autofocus up to f/5.6). Canon's version is a third of a stop faster when fully zoomed in, which means that autofocusing is more reliable, and the lens is slightly faster as well. It is almost functionally identical to the Canon 28-300L lens, which also has image stabilization and comparable apertures and focal lengths when mounted on a 35mm (or full-frame) camera. Reviews indicate that the 18-200 does not compare to the 28-300L in terms of image quality, though this is understandable since the latter is priced much higher, due to it belonging to the L-series line. Most reviewers have criticised the lens for high levels of barrel distortion at the wide end, and chromatic aberration and softness evident at all focal lengths and apertures. The lack of an UltraSonic Motor has also been noted by reviewers, and along with the 18-55 IS has given rise to concerns that Canon may be moving towards removing USM from their lower-end lenses. It has generally been rated higher than Sigma and Tamron's offerings however, and has gotten generally positive reviews with the caveat that it is designed for convenience rather than image quality.

An excellent general-purpose lens

07/03/2010

I was looking for a lens that could be left on-camera pretty much full-time; one that covered the full range of focal lengths I felt I needed. The 18~200 EF-S is just such a lens, and given its wide zoom range it still manages to be reasonably 'fast' too. The disappointment of it not being a USM ring motor design faded quickly once I discovered how fast focusing is with this lens. Subjects instantly snap into focus. I haven't had the opportunity to try it with other camera bodies, but I doubt it would be sluggish on any other model.
The image stabilization is very impressive. It's so cool when you press the shutter-release half way and the jittery viewfinder image solidifies, or at least becomes more treacle-like. It won't make your tripod redundant, but it does improve handheld shooting considerably, especially at the 200mm end.
The lens does extend under its own weight, but why would this be a problem to anyone? Adding this lens to your camera does make it a heavy combination, so you'll likely be holding it by the lens as well as the camera anyway.
I haven't held the lens up to the rigeur of scientific scrutiny as far as optical performance goes. That's not really my thing. Life's too short. A very slight barrel distortion in my pics of Torremolinos wouldn't cause me any sleepless nights. I've taken lots of pictures with this lens and I'm more than happy with it.

A great general purpose lens

19/03/2009

I recenltly purchased the Canon EF-S 18-200mm f/3.5-5.6 IS as a replacment for the EF-S 18-55mm f/3.5-5.6 kit lens that came with my Canon EOS 450D. The build quality is very good especially compared to kit lens which feels a lot cheaper by comparison. The auto focus speed is reasonable, IS is excellent and the wide focal length zoom range very useful.

I see that a lot of people are compaining about the lens self-extending under its own weight. It personally doesn't bother me too much. Holding the zoom ring in place does the job. Plus the zoom lock is handy when the camera isn't being used.

All in all, a great general purpose lens for the money considering the wide zoom range available and reasonable optical quality.

Canon 18-200mm

Canon have at last created a genuine all purpose lens. The image quality is first rate for a lens with this range but there are some misgivings. The lens does extend and retract under its own weight when pointed up or down though this will not be a problem for me and there is a lens lock to stop this happening in transit. The centre image quality is excellent though needs stopping down a little for edge sharpness. I would heartily recommend this lens as a holiday/ General purpose lens but the cost is rather high and it is definitely no L lens. The IS is superb when the light is not too good and though quite fast the USM would have been a welcome addition. All in all good to very good but not stella.

Good lens...does what it should.

14/11/2008

I'm only writing this to correct any mis-representation in previous reviews. Some people only write to complain...and aren't using the product correctly. This is a compromise lens, designed to cover a wide and commonly used focal range. As such it can't be optically 'perfect' but for the majority of peoples needs I believe it does the job superbly. I'm more than impressed with its optical performance. What it does provide is convenience and speed, great for taking those opportunist pictures that all too often seem to vanish whilst fiddling to change to other lenses of different focal length. It will be great for traveling and holidays as a 'one only' lens.
The image stabilisation is impressive and also works well with panning. Autofocus is fast although it lacks USM...which would have cost more. The build quality is much better than I expected...it is surprisingly chunky and weighty...and there are no untoward rattles! As stated, the image quality is good.
If I had one criticism it's a general Canon one...they never supply a lens hood for the price (unlike Nikon), and the lens specific hoods are always ridiculously over-priced for bits of plastic. Canon take note!
'Zoom creep' as described by another reviwer isn't really an issue, any more than with any other weighty zoom lens...even of 'L' quality. A zoom lock is built into the lens if required. I must say I haven't had to use it.
I have already had a photograph on local television with this lens within a couple of days of owning it. I think it's great...and no regrets.

Cano 18-200mm Zoom Lens self-extends under its own weight

05/11/2008

When pointing this lens directly downwards, and if the lens is set to any greater telephoto setting than 24mm, the weight of the lens itself causes it to "fall out" to closer to its maximum telephoto setting. If pointed directly upwards, a similar reaction is triggered at any telephoto setting less than about 140 - it falls in to about 24, all by itself!
Anticipating that this was just a one-off faulty lens, I returned it to Jessops, in Birmingham, who had a new replacement Canon 18-200mm lens which they swapped for me. The new replacement displayed exactly the same lack of control over the zoom positioning when the lens is held directly downwards, or upwards.
I have reported this to Canon's Technical Department and await their response...
