70-200 f2.8 II with Canon 2x TC III (also with 12mm tube)
Dec 16, 2010

I picked-up 2xTC III this morning (actually arrived yesterday)

here is
70-200 f2.8 II with Canon 2x TC III (also with 12mm tube)

moderate to poor light...
but the 2xTC III is 'trying' to be sharp enough...

this shot with a 12mm tube
5D2, 70-200 II and 2xTC III....slight crop

this one with out the tube ...the first hour I had the TC

maybe a little more light and a little better technique will help ...somewhat

but the 1.4x Tamron SpPro TC on the 70-200 II
does great for me

this was in better light with the tam 1.4x ($200)

crop for the eye detail

of coures on the 70-200 f4 I had to manual focus... (goes 2 stops to f8)
but the 1DmkIII did autofocus ok..
all were noticeably slower ...

not sure I really want to USE a 2xTC....
will try for a few more days ...then decide...

maybe I will get the 1.4 TC III and occasionally stack the two of them...

but
$500 would almost buy a spare camera....gasp!

I feel a little more confident that this 2TC will be 'acceptable' on a new 300mm f2.8.... for somebody

more fiddling....
