Focusing Question
 
I just recieved my XL2 with the 16x manual servo lens and .6x wide angle adapter. I set the back focus for the lens then added the wide angle adapter and I had to set it agian. Will I have to reset the back focus everytime I use the wide angle adapter?

Alex, if its at all possible, you should check your back focus every time you mount the lens.
Cheers.

How do you check the back focus on an XL lens ? Does the 16x have an adjustable rear element ?

Only the 16x manual lens has an adjustable back focus. The standard autofocus lens that comes with the XL2 doesn't have it.

EDIT: The (older) 14x manual lens probably has it too, but I don't know for sure.

Yes, the 14x lens has it to, and the adjustment is the same procedure.

Interesting, I had no idea. What does the 16x cost approximately ?

Depends on where you get it, but used about $600 to $800.

It's a super lens Allen, http://www.dvinfo.net/canon/articles/article82.php

I've got one, it's a lot lighter than that 20x monster as well! About £1100 new.

$600? Never seen one that cheap, you are looking $800 - $900 for a used one in good shape.

In fact, there's one listed in our classifieds now, asking price $950.

I sold my two 16X manual lenses for a bit less than that. Definitely a nice lens to have in the arsenal.

Yeah it looks like an economy version of the Canon lenses I use at work ? Personally I think it must be worth the money just for the manual focus. I'm a little bemused that they dropped the manual iris ring between the 14x and 16x models. That's also something I would consider to be an essential of a good lens set up...
