I thought that after all those lens reviews from me with Siemens-stars, white dwarfs and other dubious test-shots, it would be nice for you to see some of the test applied to my trusty old Nikon VR 18-200mm.
So here's the truth about this famous lens in a way that you can compare it to my Big ultra-long zoom review and
my Big ultra-wide zoom review
: left=100% centre
-crop, right=100% upper-right
-crop; first f3.5
(click through to the original pic):
The grey disk diameters turn out to be
at 18mm f3.5 centre 7mm, corner 7-8mm
at 18mm f8 centre 6mm, corner 6.5-8mm
Also you can see some slight deterioration in contrast of the corner-crop against the centre-crop, but that looks quite ok.
As to the tele-quality, here is the shot that can be compared to the other long lenses albeit being only 200mm
where the other lenses have been shot at 400mm (first at f5.6
, then f8
In this case the Nikon VR 80-400mm really shines, but tstill the VR 18-200mm can give you some decent tele-shots.
Now on to flare
. Worst case with this lens is contra-light dead on and you will see (at 18mm f4) that this situation has to be avoided at all cost
, as the flare is with the worst of all tested wide-anle lenses! Whereas when the light-source (aka sun) is off-centre, flare is well under control
