70-200 is I vs ii:tc usage
« on: December 01, 2012, 09:54:04 PM »
Hey guys, I'm picking out the next telephoto zoom to upgrade to.
My question is, is the version ii going to have better image quality with converters.

Extra:
1. Would the version ii 70-200 work with version ii converters
2. Would the version ii converters work better with the 70-200 mark I
3. Is it important to purchase mark iii converters for the 70-200 ii

Yes - in fact the iii extender became available well after the lens was released.

Not 100% sure on that, but I believe they did make some optical improvements so I'd expect so.

3. Is it important to purchase mark iii converters for the 70-200 ii
The mark iii has weather sealing and is a little better optically. It has some AF speed improvements with newer super-teles but I don't think those changes make a difference on the 70-200. Guess it's up to you if the extra $$$ are worth a small improvement, but either will work fine.

As for your main question I think the 70-200 II is considered to have better IQ than the 70-200 I in just about all regards, so the same will apply when using an extender even more so. The II version also has faster autofocus which will help when using an extender, which slows down AF.

With converter, it seems you lose more than you gain.

1. Gain - reach

2. Lose - light, focus, and shutter speed

I prefer "cropping" on raw. It works well for me, might not apply to everyoe else of course.
Body: 1DX -- 5D III
Zoom: 16-35L f4 IS -- 24-70L II -- 70-200L f2.8 IS II
Prime: 40mm -- 85L II -- 135L -- 200L f2 IS -- 400L f2.8 IS II

The question is confusing me - you've said before that you already have a 70-200mm L IS II.

mysituation is confusing, i know. what happens, is that the 70-200 is my uncles, i borrow it often, but because his professional, his season for christmas cards, senior portraits, and soon to be weddings kepp him hogging it, id like to purchase my own, and i love the mark ii, but i cant justify the purchase.
I may even buy the new tamron when it is releasedand get the kenko tubes

Any of Canon's 1.4x extenders will work with any version of the 70-200mm. The 1.4x III offers improved AF tracking with the IS II lens and slightly lower CA. If you go for the IS II, the 1.4x III would be the best choice of Canon extender. If you go for a used IS Mk I, the benefit of the 1.4x III over the 1.4x II is less clear but still the better choice, all other things being equal.

Users of the Kenko Pro 300 DGX usually report very good results.

With any teleconverter, sample variation between it, the lens and the body may be a bigger factor so a body with AFMA would be an advantage.
