p.1 #1 · Which of the following 3 would be sharper / focus better around 400mm?


70-200 II with a 2x TC
100-400 L
300 / F4 with a 1.4x TC (I know, 420mm).

Camera body = 5d3 - just trying to decide my options here to get nice 5.6 shots @ around 400mm.

Thanks,
Shawn

My vote would go to the 100-400L out of this group. (there is no 70-400L)

100-400L most likely.

Ever think of the 400 f/5.6? Best you can get.. But if you need IS, the 100-400.

Well I already have the 70-200 II; I was secretly hoping someone would say it's fine @ 400mm @ F/5.6 with the 2x on. I'd rather spend $400 on a 2x ETC than get another lens.

Coming clean now...

It kind of depends on your definition of "fine," and how much you care about the very slight difference in IQ between the 70-200 II with 2xIII and the 100-400, between 280 and 400.

This question has been asked many times, and the consensus is that the 70-200 II with 1.4x is sharper than the 100-400 from 200 to 280. Obviously, the 70-200 II is sharper from 70 -200. And the 100-400 may be slightly sharper from 280-400.

I like the 70-200 + 2xIII just fine for those times when I don't have my 500/4, but want the longest focal length I can get. I've been quite satisfied with my results with the 70-200 II + 2xIII.

I'm not trying to sell my photos, but I know the difference between sharp and not sharp (and I don't much care about pixel-peeping to find microscopic differences).

YMMV

Whats the AF penalty like with the 1.4 on the 70-200II vs the 100-400 on the 5d3? Real experiences please, not quotes from white papers

The 1.4x doesn't affect the AF much. From lightning fast to pretty fast.
The 2x, even the mark III, really slows down the AF. Mine hunts for focus sometimes without very good light. You barely feel the 1.4x is there.

I've owned and used all three combinations, with 1DsIII and/or 1DX. If I know I'll be using 400mm, I generally take the 100-400L, but the other combinations work fine for most purposes. I took my 70-200/2.8L IS II + 2x III to Utah last summer, as I was shooting some indoor events, and it worked pretty good outside at 400mm, too.

I posted a comparison of the 70-200L II + 2xIII and 100-400L here,

http://www.fredmiranda.com/forum/topic/1154527

I've also included below an example of the 70-200L II + 2xIII on 1DsIII at 400mm, from my trip to Utah last summer. It's been posted before, but I can't find the thread. The first image shows the entire photo and the second is a 100% crop of the birdies.

A lot of folks go though the process of comparing the pluses and minuses of those three options. On one hand, your question about which will be sharper at 400mm could be the determining factor, though I also think that some practical/functional questions might be at least as important.

In truth, you can get a good 400mm photograph from any of those options - not one among them fails to be "sharp." (Some would point out that if your only criterion is shooting at 400mm a 400mm prime would likely be worth consideration.) With that in mind, I'd consider framing the question a bit differently.

If you intend to shoot a whole lot at 300mm (though you did not mention this) and only occasionally have to extend to get a bit longer at 420mm, then the 300mm prime plus 1.4x TC could make sense.

If your primary need is for a large aperture zoom in the 70-200mm range and you will only occasionally need to shoot at the longer focal length, then the 70-200 plus 2x TC could make sense.

If you want flexibility to quickly cover any focal length in the 100-400 range without changing lenses, the 100-400mm zoom could be your best choice.

If you only or primarily are concerned with shooting at 400mm, then a 400mm prime could be a better choices.

To play this out a bit... if your main goal is being able to have a 400mm lens, I would not recommend any solution that requires you to use a TC. The main issue is that adding/subtracting a TC from your lens is an extra bother that makes sense for extending the primary functionality of your lens to allow a secondary functionality, but (usually) not the idea solution for solving your primary need. Instead, I would consider the 400mm prime or, more likely, the 100-400mm zoom. With the latter, one lens will cover all of your needs - and I note that you mentioned f/5.6 as your primary aperture - with no need to switch lenses or add/subtract a TC.

For me this was the deciding factor and why I have both a 70-200 and a 100-400. The TC is not just a bother its a pain especially when you lose a real good opportunity because you had to switch. When you need more or less FL its faster just to switch lenses, or better still, pick up that spare camera with the other lens attached.

My experience here, with the the caveat I have not used any of the other lenses...

http://pmorphoto.wordpress.com/2012/04/20/testing-canons-2x-tc-viii-with-my-70-200-f2-8-vii/

Short version, 70-200 with 2x is fine, unless you need to focus quickly.

I'm right there with Dan and SBS. I have the 70-200 II, the 400 5.6, and the 100-400 and TCs. I almost always carry the 100-400 out on my kayak. This last weekend I grabbed the 400 prime. I came across a 14' male aligator with an 8' female on the bank and just could not get the right framing with the prime.

Bottom line for me, the 70-200 with 2X works okay but is an awkward sized package and just doesn't feel right, the 400 prime is great but no flexibility or IS, the 100-400 is my lens of choice for size, flexibility, and quality for up to 400mm. Haven't owned a 300 f4 though.

Thanks for all the replies. Since I already have the 70-200 II, I think I'm just going to grab a 2x converter and be done with it. I can't afford a 70-400 right now.

That's the smartest thing, and will only set you back $400-500. You'll want the latest version 2X III.

I went with the 100-400 plus 1.4X II and am happy, but I didn't have a 70-200/2.8 II.

When I bought my 70-200II I also bought 2xIII. Tested on my 1DsII against my 100-400L, I sold the 100-400 ! 70-200II+2xIII (at least mine) is tack sharp at 400@5.6, I was really surprised when first seeing the raws. Now if you need more responsive AF, 100-400L is better, and quality wise not far behind. It may also depends of your copy of 100-400, mine has allways been a bit soft at 400@5.6.

Cheers
