70-200 w/ 2x extender VS. 100-400

I know I stand a chance of getting ridiculed for this but...just give a little help to a newbie

As the subject line says, How would the 70-200 w/2x extender compare to the 100-400? I know I want to buy the 70-200 f2.8 IS model, just wondering if you add the extender how would it compare to the 100-400? I assume that it will work but not as well as the real thing. But does anyone have first hand experience or anyone with an educated opinion?

i dont have first hand experience but ive been on that boat a few weeks ago (ended up giong for the 100-400)

this seemed to be useful

I have no first hand experience with it, but I've been going through the same debate for a while now. I think that I lean toward the 2.8 IS and TC, simply because the resolution loss (stopped down at least) isn't big enough between the two to justify missing out on having the ability to shoot at 2.8. The 100-400 is obviously better at 400, but I just think that you get so much more with the 2.8/TC combo.

Which version of the 70-200 and what body?
If it's the f4 and you have a non-1 series body, then you lose AF.

AF will be slow, and you will lose a lot more IQ than the 1.4x TC. The 70-200 + 2x TC would definitely be inferior to the 100-400L.

If you don't plan on using 200-400mm that much, then the TC is a good option.

However, if you are going to be using that range regularly, then I would not recommend the 2x TC.

Just rent a long lens for that trip.

No sense in buying a lens just for a trip...

Well...chuck steak to fillet would be a more "family friendly" comparison. I agree that a good copy of the 100-400 is the best choice between the two options.

i didn't use chuck steak because while it may not be the best cut it would be one that i would eat .

Used LensRentals before and would recommend them easily.

The 100-400mm will be sharper than the 70-200mm with the tc.

from what ppl tell me, i understand you need to stop down to f/11 on the 2x and 70-200 to get any sharpness
And TBH my 100-400 is damm sharp at 5.6

100-400 would be superior is every way.

Just buy one...their a FANTASTIC lens!
