p.1 #1 · p.1 #1 · 1.4 Tele Extender v. II vs III


Thinking of picking up a used TE v II for my 5D III w 100 - 400L v.1 ..
Any thoughts on the v. II TE ??
I belive pricey v. III is for mark II lens only but I do have 70 - 200L 2.8 v. 2

For that lens and body The Mk II will be just as good. The VIII is worth it for the 2xTC for IQ. The 1.4 is only worth it on the newest MKII supertelephoto and on cameras like 80D, 5D4 and 1DX2 that require the the MKIII to get more f/8 points. I don't think 70-200II has a benefit from it. I think Rudy Winston or Chuck Wesfall confirmed this in the past. The 80D only benefits if used with 100-400II.

Basic IQ is equal between Mk2 and Mk3 for the 1.4. But the Mk3 allows better AF with the MkII big whites as their is an extra chip in the TC that talks to the new lenses.

Like I thought.
New v. III does seem practical for this lens and camera.
It should give me just a bit more reach when shooting Puffins from boat off island in Iceland.
Or ... I could pick up a 70d. (??)
Auto Focus on 5D III and 100 400L v.1
and v. 2 1.4 TE ??
Auto Focus on 70D w/ or w/o said TE and
same lens ??

A side note just for fun.

I have the EF1.4x from 1990, the Mark II from about 2000, and the Mark III from a couple of years ago. All take the same AFMA setting on all of the relevant lenses, from a 1990 600/4L, to a 2000 400/2.8 L IS to a 2016 500/4L IS ii, and the 70-200/2.8L IS and 100-400 L IS ii. I can see no optical difference between them even with some serious pixel peeping.

The Mark III is the one to get if you have one of the Mark II great whites because of the faster and more consistently accurate focusing and if you have one of the latest bodies which can benefit from its internal computer chip. But if not, it seems the converters are very durable and consistent and an older model used might save some bucks while offering the same performance as a new late model.

My choice would be 5D3 with 100-400 and 1.4TCII (or III).

I prefer TC on FF vs no TC on crop most of the time. 5D3 AF is a much more advanced system than 70D. Here are a couple images with 5D3, 100-400 and 1.4TCIII

The 70D won't AF with a 100-400 and 1.4x but the 80D will.

Thanks all for inputs.
I will pick up a used v.II or just get closer.
Get closer is always best and cheapest.
