Q. What is the sharpest Canon lens?

Opera works fine with XP, (& other versions of 'Doze), & is greatly
superior to IE in speed, security & convenience.

Kibo informs me that stated that:

"You obviously don't shoot with long focal lengths often.

Even WITH the tripod IS is very useful."

I use a 560mm f/6,8 Leitz Telyt-R all the time. It is designed as a
hand-held lens, as is the 400mm of the same speed.

I have successfully hand-held this lens at 1/30 sec without any damned
stabilization.

I don't believe you. The only way I'd believe a wild claim like that
would be to see it in person.

The fact that Nikon and Leica won't use it isn't good enough for you?

That is because Canon have patents on using it for Camera lenses,
and a butt load of key patents on making the stuff. As a result,
Canon are rumoured to make more profit from a Nikon Mask Stepper
than Nikon do...

Canon have been using it since the FL-F lenses of `70 or there
abouts.

It's hard to work with and Leica, for one, doesn't feel its
advantages
are sufficient to make it worth adopting. Leica has access to glass
that the other firms don't, which is part of the reason.

The advantages of CaF2 aren't really utilized until you need correction
substantially into the ultraviolet or infrared, or both. CaF2 is
absolutely essential in lenses like the UV-Nikkor, for example.

For ordinary visible light lenses a standard commercial glass like
FPL53 is nearly equivalent to CaF2 in optical properties and has
slightly better thermal properties.

There are several commercial optical glass makers producing a full
range of glass types which anyone can buy. Leica has no advantage
here.

Seriously though, you don't have to use IE you know. I understand that
Firefox is now a very popular browser for Windows users, and I hear from my
Windows using colleagues that it makes IE look very primative in comparison.
Maybe it's worth checking out?

You don't need to install another operating system to install another
browser.

I guess you don't care about sharpness.
