Here is a shot I captured last night with my 7D + 1.4x TC III + 2x TC III + 300 f/2.8 IS II with a Kenko 12mm extension tube between the two TCs. The rig is a little too heavy for my tripod head, which started to drift, so this shot was hand held. :)

Thanks for the moon shot, the combination of lenses is just what I am interested in.  Did you manually focus? It would be interesting to see 100% crops with and without the 1.4xTC.

Being that the framing was difficult to hold on the incline of my back yard, I was trying not to fall in a hole, I first used autofocus to find the ballpark. Then I switched the lens to manual focus and adjusted the focus ring to dial it in while resting my hands on top of the fence. Here is a 100% crop of the lower portion of the moon where the best detail resides. I will have to get back to you on the 'without' image. :)

I'm also going to be getting a new tripod rig so hopefully I can do some better focussed images once that arrives. I will also do some cropped tests with my 5DIII, too.

Impressive, I'll buy a 12mm ring. Here is a photo I took last April using the 5DIII + 2xTC. I've increased the pixwl dimension by 1.4x1.6 to allow for the crop factor and the TC used by you. I haven't sharpened or noise reduced the image.

Very nice. What lens were you using? The Kenko extension tubes allow autofocus, so I would get them over the cheaper ones. Also note they are only in a kit for $199 with a 12mm, a 20mm and a 36mm tube. The Canon 12mm is sold alone for $84. The product description does not state it, but I am sure theirs is compatible with the AF as well.

f/2.8 300mm II + 2xTC III. I will go for the Canon because I presume it is strong enough to marry a monster lens to a heavy body without snapping in two.

OK, Sorry.  I think I wrote out all my text and copied the photo over the top.

I tried the 2XIII and 1.4XIII with a 13mm extender a friend of mine has.  My 1D IV said Error!
My 5D III said, OK, but I can't focus.  And My friend's 7D said...Error.

The Photo is actually just the 2X on my 400mm with my Mark IV

Have you tried shooting the planets (Mars, Jupiter, Saturn)?  I've used a 300 f/4 + 1.4x+2x and you could barely make out Jupiter and 4 moons if you digitally zoomed in quite a bit.  I figure you need a 4000mm lens equivalent before it would be like a telescope.

If I had more free time and a few thousand dollars to play with, I would buy a GPS tracking telescope and mount my camera on to it.  Then learn how to stack images in post processing.

The moon shots were posted just as universal images for comparisons. I am interested in extra range for nature shots.

The Canon 12mm II just arrived. My 5DIII won't focus either manually or AF with the 1.4x III -12mm - 2x (or vice versa). What am I doing wrong? Does anyone want to buy a 12 mm Canon II extension ring, 1 day old, used twice?

He seems to have a 1DX. And the 1.4x is the first one mounted. Not sure if that matters. I tried my 5D3+1.4x+12mm+100-400L @400mm and it did not AF. Even manual focus was not possible. My 12mm macro extension tube is Kenko but I don't think that is the problem.

I guess this is one for Alex to field...

Why no manual focus? The focus ring is stuck?

Nope. Even going beyond infinity, objects at infinity do not come into focus.  :(

If the extension tubed has other uses of course.  Marco for one.  Also, it makes a good way to keep the 2 extenders in your camera bag.

Just for fun: Kenko 3x TC (live view focusing only) on a 70-300L f/4 (900mm equiv.) on a 6D
