But - after focusing starts continue to focus properly, but only in the range of footage.

01.08.2008 15:48:00

me to just focus range. . .

and with it the distance that must drive lenses.

This is what normal? 1, 5-8 or 3-8? I
3-8. I'm at 135/2 to such rakes came. I thought brake lens compared to 85/1. 8
at long range, osoblya if not caught immediately, chasing dolshe- fact!

01.08.2008 19:28:00

A buyer discovered troubles?
what? Troubles come to a head when the switch is in the range of short-range and try to shoot everything. That's when the brake and start. and the lens-then everything is fine.


This is what normal? 1, 5-8, or 3-8
normal this further. What there just tsiferki were already forgotten. Now I have the same at 135/2, 0 is - is the switch to 0. 9 forget it begins.

01.08.2008 19:50:00

So my real troubles glass, compared to yours

Clarifies some details.
1) Okaztstsa focus goes normally from distant positions (eg infinity) to a near.
from the Middle same long - almost did not move.
2) Was the interview in the local SC Capop.
They sent a request to Moscow Canon (representative office in the Russian Federation, the. Department) that it supplies and advises AF. The answer is no (master complains that they are responsible and are reluctant to send their AF)

Now when shooting pinky dokruchivayu focus wheel against emergencies (ie. E. In the direction of infinity), and only then normally focused.

course efficiency is lost.
I will wait for messages from the response of the SC Mosk. Canon-a

Here. . .
