Canon 1.4X III vs Canon 2.0X III
« on: April 12, 2013, 02:13:29 PM »
I am looking at both the Canon 1.4X III and Canon 2.0X III.  What I am confused is why they are both at the same price.  Been reading some reviews on the web, but given that both are the same price, which one to choose?  I am aware of the loss of 1 or 2 stops of light as well as image quality being not as sharp.  I have a 7D and 5D3 with  70-200 2.8 II.  I would love the notion of extending the reach to 640mm on my 7D, but I don't know if that means that my image quality would suffer greatly or settle for the 1.4X and be limited to 448mm.  Or I can settle for 280mm or 400mm on my 5D3.  My intent for the extra reach would be for wild life. 

Any advise?  Thanks in advance.

The 2x does well on the 70-200 II.

The 2x only makes sense if your target is too small to fill the frame on 200mm with the 1.4x on a crop camera.

I agree with Neuro the 2XIII works great on the 70-200 II if you can live with F5.6 wide open.  Sweet spot with the combo is around F/8.  Note also that the AF speed drops...not by a lot but it is noticeable.  Birds in flight can be a challenge for it but not impossible.  You wont be happy with the reach using the 1.4X.  Where the 1.4 comes in handy is when you are using the Large tele's 300MM and higher.

Agreed - I use the 1.4xIII on my 600 II (and occasionally on my 100-400), but never on my 70-200 II.

I've had both the EX 1.4 and 2x in the II models. As East Wind already posted, the 1.4 is excellent on the 300/2.8. On the other hand, I used the 2x on my original 70-200/2.8 IS and the results were totally useless. Last year, when I replaced my zoom with the version II, I also got the latest 2x extender. The AF is a little slow, but still very useble and the IQ is so much better!

I use both 1.4 ll and 2X ll Extenders on my 70-200 F4 IS USM lens. 70-200 + 1.4 is my walk around BIF combo. I find no
image loss with this combo. Using the 2X hand held the pics are a little soft but usable. Mounted on a tripod and live view
F11 or 16 and a cable release. I got a pair of Eagles in a tree that I use as my desktop pic. It was shot at F16 on a nice sunny day. I bought the 1.4 Extender with the 70-200 and used this for 2 years before buying the 2X. We will always want more reach with our lenses. LOL 2X is manual focus for me which wasn't easy with live view because of the light hitting the LCD.

The 70-200 II might be good enough to take it well. It's a little dicey on even the 70-200 f/4 IS (it still pulls in a trace more detail than upscaling with the 1.4 or bare lens but it is starting to get ugly enough that I'm not sure it is worth that tiny bit of extra detail). But I hear that it works better on the 70-200 II.

On my 300 2.8 IS I've ended up using the 2x almost all of the time now. Sure you don't get the crazy micro-contrat of the bare lens or the close to that that you do with the 1.4x on but it still looks pretty decent, sort of like a bare tamron 70-300 at 300, and the extra detail it brings in is well worth it. Even 600mm is often frightfully short for birds, even on APS-C 7D and for sure on 5D3 so I don't use the 1.4x as much (unless I am in a special close blind scenario or shooting really large birds from a decently close distance). I even used it with the 2x for surfing to pretty good effect. The surfers are far away enough that the greatly slowed down close tracking speed doesn't matter enough to make it that bad.

I know this is not what you asked, but I use the 70-300L rather than 70-200 w/ 1.4x. About the same range on the long end but much lighter. 

I used the 1.4x on the 70-200 until I got the 70-300L.

I use the 2X on both the 70-200 2.8 II and the 300 2.8 IS for stationary subjects when there is no other way to get the shot.  As has been mentioned by others; to get the best from either combination requires good technique,  stop down a bit,  tripod,  remote release, good post work flow. 

Otherwise, my opinion is that the results do not meet my image quality standards.  And BIF with 2x,  forget about it. 

Here's an example shot with the 7D,  300 2.8 IS,  2X TC MK II.

Yep. I use the 1.4x on my 300mm f4 and it works well. Plus, running it on my 5D3 limits me to f5.6 as it is.
But, yes, in your setup, the x2 would be preferred.

Thanks to all for sharing your wealth of knowledge.  That's why I keep coming back to this forum.  With the feedback I received, Canon 2.0X III it is...  No doubt about it.

Thanks again!

I have the 1.4x mk.3, but I have never used a 2x TC. 

I find the 1.4 x does not do a whole lot on my FF camera with a 70-200 lens, as others have said here.  But it actually did make a big difference on my crop body, as long as you are not shooting tiny things like birds or squirrels. 

My feeling on birds is that they are terribly cheap, and will seldom pay much for even a great portrait of themselves.  Spending $7k on a bird lens would take forever to recoup in shiny bits of junk and sunflower seeds.

My kindergartener plays soccer on a midget field, and the 1.4x would make the lens too long to shoot that.

Come to think of it, she never pays anything for her photos either!  ;)

I use the 1.4x (II) a fair amount with the TS-E 24 II. I don't think I've ever used the 2x with that lens, and I have a hard time imagining a time when I would.

Cheers,
