I need informations on this lens: Canon H20ax6 (IRSS x12), which I am offered with a F350.

A Google search did not really give something.

Can someone here tell me more about this lens ???

Canon has no lens like that.

Probably it is the KH20x6.4 KRS. This is the standard lens that is included with the PDW-F335K2 package.

There also is HJ serie of lenses, but they 2/3" and have a zoom ratio like 11x, 17x, 18x, 21x and 22x. I doubt if it is one of these.

No, it is not the KH20x6,4.

A Google search shows me that the H20ax6 has been available, but there is no informations on it anymore. I was hoping that someone knows this lens, and could tell me about how it performs.

I also found something on a Russian website and guess this is an (very) old model. Be careful with it.
