Finally I come across a new and different kind of
thread that sounds exciting and it's a mistake!
Ok I guess it's back to
which has the better AF the 1n or the 10d.

Javier,
Since we are also members of that other list where a similar OT thread
began you know what the outcome would be.
As to the 10D v. 1N, the 1N is faster by far. The 10D AF is like an Elan
IIe AF vs. and EOS 1N.
In 1997 the magazine Colorfoto conducted a test on AF speeds. Use the
EOS 50 as a 10D and you will see the 1N is faster.
ColorFoto measured AF speed, AF accuracy and AE accuracy. The rating
was based on all three tests. Since the AF accuracy was within the DOF
for all tested cameras, the final rating is useless.
The interesting part was AF speed. They tested with a 50/1.4 lens.
The results in seconds at EV 15, 10, 5 and 0:
Nikon F5: 0.19, 0.19, 0.29, 0.41
Canon EOS-1n: 0.23, 0.23, 0.33, 0.51 (w or w/o booster)
Nikon F90X: 0.26, 0.26, 0.35, 0.53
Pentax Z-1p: 0.27, 0.29, 0.39, 0.58
Pentax MZ-5: 0.28, 0.31, 0.40, 0.61
Minolta 700si: 0.27, 0.32, 0.40, 0.60
Nikon F70: 0.30, 0.30, 0.39, 0.78
Canon EOS-5: 0.30, 0.34, 0.42, 0.60
Canon EOS-50: 0.33, 0.37, 0.43, 0.63
Minolta 500si: 0.40, 0.40, 0.45, 0.67
Contax AX: 0.39, 0.42, 0.50, 0.60 (back focus in body with MF
lens)
Canon EOS-500N: 0.45, 0.52, 0.49, 0.73
Minolta 300si: 0.47, 0.50, 0.53, 0.72
Nikon F50: 0.49, 0.50, 0.52, 0.75
Pentax MZ-50: 0.49, 0.49, 0.56, 0.79
Sigma SA-5: 0.56, 0.57, 0.61, 0.80
AE accuracy was within 1/3 stop for almost all cameras. Some low-end
cameras was biased towards overexposure that is best for print film.
