- 1.4 ExtenderWorks great when paired with my 100-400mm and 80d!
- Great extender for my needsOutstanding images with this in conjunction with my 300mmF2.8L. Frustrating that it does not work with the 100-400 F4.5L ll USM, while it did work with the original version of this lens, (although this was not consistent).
- not for a t6ithis extender did not work with my rebel t6i, my disappointed
- Excellent addition.Using it on my 70-200 IS USM version 2. Was really surprised by how well it works. So glad I spent the extra money. Well worth buying if you have a need for it. Wish I would have had it sooner because of all the pics I took before owning it.
- Not happy with the autofocusNot happy with the failure of auto focus while using my EF 100-400 zoom lense. It only works if I use the screen mode instead of the view finder to shoot.
