An image with details fairly soft! Had to do some considerable sharpening to make it look worthwhile
Just had to try it for the heck of it. Talk about a huge privacy destruction lens with the TC attached to it.

TCs do soften up the image noticeable regardless if I'm shooting the moon or the neighbour across the, eh, never mind :p
<center><img src="http://pictureposter.audiworld.com/64400/moon-1.jpg"></center><p>The 100-400L is a 'good' lens, but not all that 'tack' sharp to begin with.
Here is a shot I took last month with the 1.4xII Canon, on a Canon 600 f4L prime.
I use the Canon 1.4xII on my 600 all the time.
You can NOT tell the difference with it on the lens.
The 2x, now that's a whole other story.... ;D
This is full frame and almost NO USM added.
Funny, I saw the moon last night and wished I shot it too..

I did a little sharpen pass on it and pulled the blue down (using Gimp)

Agreed, always a comprimise when using zooms. Primes are nice but not sure if I'll get the full use of one especially at that length, but it would be nice to have still.
My point was mainly, that a good TC won't degrade the quality of a quality lens.
With any good L prime, you won't see any degradation from the 1.4xII tc..(300 2.8L, 400 2.8L, etc...)
Of course with a zoom, it's going to be dependant on which one.
Full use of a 600 f4L is only for sports mainly.
It's my most expensive lens yes, but it's NOT my most used either.
It's a specialty lens for sure.
Works great on subjects, 1000's of miles away huh ? ;-)
It occasionaly gets used for models or cars as well....

substantially worse job. For instance Tamron 1.4x, Kenko 1.5x or new Tokina 2x? TIA.
Remember, you get what you pay for.
You are paying less, because it is inferior glass.
I also think that TC's are last resort items.
I do not use mine, unless I have to.
IF you have Canon gear.
Get a Canon 1.4xII and a 3rd party version.
Do some tests. There WILL be noticeable differences.
Especailly, in this day and age with HIGH res digital camera sensors that are starting to OUT RESOLVE the glass we put in front of it.
If using a TC, spend the extra money. It's worth it when you use it.
Not only will the be sharper, but also have much better contrast.
