Build and Handling
The build of this lens feels far too lightweight to inspire any confidence in its ability to last. The lightness is attributable to the very simple (for a zoom) construction. Gone is any semblance of a manual focus ring although, once switched to Manual with the small slide switch on the left of the barrel, manual operation is possible by turning the front element. It is not possible to override the autofocus by this method though. That just leaves the zoom ring to occupy the majority of the barrel and does so with 2/3rds of the length covered in a rubberised, ribbed grip. The ring is marked at 55, 70, 100, 135 and 200mm marks. Zooming to the long end extends the front element by some 43mm and a further 11mm is added at the closest focus point of 1.2m. There is no distance scale on the lens and no depth-of-field scale either.
Autofocus is quiet and relatively accurate and, although a little slow for some things, would be perfectly adequate for most purposes. Both methods of focusing rotate the front element, causing problems when using filters that need orientation.
Engineering plastics have come a long way over the last decade or two and the light weight produced by use of these materials and their shock absorbing nature may prove my concerns about this lens’s longevity unfounded but the mount, also of plastic, is likely to suffer against a metal camera and wear if much lens changing is practiced! There is also considerable lateral movement in the extending front section of the lens where it exits the main barrel and I can see dirt getting in if the unit is not well looked after.
With no hood supplied, and the mounting flange for it just forward of the front element being rather thin, this area too must be vulnerable to the slightest knock.
As with most zoom lenses in this class, the better performance is achieved at the shorter end of the zoom range with a steady degradation as the focal length increases. This lens, however, manages to control this phenomenon fairly well, especially in the centre of the optic with more falloff noticeable toward the edge of the frame. This does not bode well for film or full-frame sensor users where results are showing poorly on a cropped sensor. The optimum aperture does shift as the focal length increases also, going from f/5.6 at the short end to nearly f/11 at full stretch.
Distortion is reasonably well controlled, with figures of 0.72% barrel at the short end varying to 0.88% pincushion at the longer focal length. With the total distortion being spread from one end to the other, the problem never becomes noticeable.
Chromatic aberration is well controlled and at no point does it give rise for concern although the contrast of this lens is a little short of Canon’s normally high standards. Colour rendition is a little more neutral than some of their older designs also.
1/1000sec at f/8 and ISO400 set at 200mm on Canon EOS 20D
Despite a high shutter speed to eliminate camera shake and a reasonable aperture this shot of an old couple out walking a nature trail has no real bite to it.
At the 55mm end and the aperture set to f/8 the results are a lot more acceptable. Shot taken to record the low water levels in a local pond.
Again at closer range there is no real bite although the out of focus highlights are nicely rendered
1/800sec at f/8 and 200mm
This time at the closest focus of 1.2m at the same 200mm, this time at f/5.6 (i.e. wide open) there are no really sharp areas.

Overall, for the price of the lens, it is an adequate performer although the over reliance on autofocus and the all-plastic construction do raise a few concerns. At the short end, and focussed on infinity, there is virtually nowhere to grip the extending part of the barrel for manual focussing. For a lens designed to be the first extra lens that new dSLR users will buy, it seems to indicate that manual focus techniques are not worth learning, something that is far from the truth.
In summary, the positive points of the Canon 55-200 f/4.5-5.6 USMII are:
Light weight and simple construction
Good control of aberrations and distortion
The negative points are:
Poor build quality
No dedicated manual focus ring
Plastic construction throughout, including mount.
No lens hood supplied.
