David,

You make an excellent point.  If I were to look at ColorFoto which is a
German publication, they seem to love any german lens.  Compare that with
CAPA, the japanese publication, they tested Resolution/Contrast using JCII
resolution chart and ISO 100 B&W film.  The results showed Tokina being the
#1 performer in several categories.  They check out Chasseurs D'Images, they
lean toward Sigma and Nikon often.  BTW, they rate the 180mm/2.8 4-star and
the Canon 200mm F1.8 4-star but the Contax 180mm F2.8 5-start.  They hate
Tamron, they rated the Tamron 20-40 as poor, yet Pop Photo and Photodo rate
the lens as outstanding.  Go figure! I guess we'll never really know.

That's interesting but at Photodo where they use Hasselblad MTF equipment to
test the lenses, the Canon 200mm F1.8 rated it as one of the highest tested
at 4.8 (out of 5).  If it were as bad as ColorFoto pointed out, then why
does it receive such raves reviews elsewhere?
Oh well.

Peter,

Not according to ColorFoto, which measured the Canon to be the LEAST
sharp of those tested. From Pascal's site, here are the ColorFoto test
results, published since 12/94:

Abbreviations:
Res. Resolution/Sharpness
Cont. Contrast
Cent. Centering
Dist. Distortion
Vign. Vignetting
Total Total sum of points

				Res. Cont. Cent. Dist. Vign. Total 
				30    30   20    10    10    100
Leica Apo-Summicron 2/180mm 	25.5  29.1 20    10    10    94.6 (Best
Lens ever)
Minolta AF 2.8 200mm APO 	22.1  27.3 18    10    10    87.4
Canon EF 2.0 135mm L USM 	23.0  26.9 16    10    8     83.9
Canon EF 3.5 180mm macro L 	22.3  26.6 15    10    10    83.9
Nikon Nikkor 2/200mm    	19.9  27.3 17    10    8     82.2
Canon EF 2.8/200mm L USM II 	21.2  26.0 15    10    10    82.2
Tokina AF 2.8 100mm AT-X m 	20.6  26.7 13    10    9     79.3
Canon EF 1.8/200mm L USM 	18.3  25.2 12    10    8     73.5

In fairness, Photodo's results seem to contradict Colorfoto's for the
Canon 200. Photodo has not posted test results on the 180 Summicron. The
"best lens ever" Colorfoto distinction for the 180 Summicron is for all
lenses. The same distinction applies to the Canon based upon the Photodo
test series/methodology.
