I am planning to buy an 1.4x extender for my 550D with 100-400L lens to shoot with.

I really don't understand the difference between 1.4x iii and 1.4x ii. Could someone please explain the difference among them? And also will it be a good to go with 550D body and 100-400L lens?

Thanks,
Anand :)



Anand,

Really, I know how you feel, wanting a little extra reach for as little as you can put out. The bad thing is, the converters really don't work very well at all with that camera, I ought to know, I have one. I have tried the Kenko 1.4 300, the Kenko 2.0, the Canon 1.4II, but I have not tried the Canon 2.0III. These things are designed for the 1D series really, I mean, they will work on other cameras, but to get full focus, you'll need the 1D's. You can get full focusing on your camera using a Kenko brand, but I promise, you will more than likely regret that decision. I tried it all with mine, and my 100-400L too, I got full focus, but it was slow, and the images looked like CRAP!
(I hope that I don't come off sounding like I am a rude know-it-all, or a jerk, I'm just trying to save you some money) :) I have since upgraded to a 1DIV with a 400-2.8 lens that will handle them all just like I wished it would've with my old cameras and lenses. I still have the T21/550D and the 100-400mm L lens, but there is no way that I would use the extenders on them.
Actually, now I can get acceptable results using two converters at the same time, (1120mm) I use 2 of the 1.4's all of the time, but no way can a T2i do that.
(To be honest, I guess it's all in what you think is acceptable, as to what "good" means to you)

Now, I will say that any lens that is a Canon 2.8 (or faster) or a f/4. 'can' work, but the degradation of the camera alone will hurt the images. Yeah, I know, a lot of people will say they have perfect luck, but you need to see the shots to prove their claims. I'm not calling people out at all, heheh, I just mean that people say theirs works.
Now I do see proof of a 70-200mm L lens working with the Canon 1.4, but it's usually on a 7D, but still, from what I understand, it's not as good as the lenses that they are made for. (From what I read on here, and reviews on Amazon, and the two main sellers here B&H and Adorama)

I honestly know how you feel, and I wish I could tell you different, but you'll more than likely place it in your bag and let it sit, just like I did if you buy one. Mine sat in my bag until recently I decided to try them on my newer camera, it worked really well, but I had to pay a LOT for that too, to be able to do that.
You'll get smeared looking shots, along with slow focusing, even with a Canon 1.4-III.

Also, from what I read, the 100-400mm L is not a good lens (or, at least the best choice) to put an extender on anyway, plus, what I know mine looked like, I wouldn't recommend that anyway. There will be people that won't agree, but I know I have read it many times here, and I know what I see on my monitor. :)

Kind of agree with the above, the teleconverters really only excel with the super prime teles over the other lenses.

I've seen some comment that the Sigma TC 2X may be better than the Canon. I've never tried a Sigma TC, but wondering if others have and their opinions? The references I have heard were vs. the Canon Version II (not the version 3). I can't afford the long teles version 2, I love the new version, as it has pushed the prices down on the version 1s !!!!!!

You won't be able to autofocus when using an extender and the 100-400L unless you have a 1D of some sort.

they will work on other cameras, but to get full focus, you'll need the 1D's.

Just a quick addendum to these statements: the 5D Mark iii will also AF with a maximum effective aperture of f/8, so 100-400 with a 1.4x will work. To my knowledge, the 5D3 is the first non-1D body to offer this.

Is this true for both the Mark ii and iii 1.4 extenders?
