A step up!!
The new mark iii 1.4x teleconverter is head and shoulders above the previous versions. I did some systematic test shots of a Coke can, two at 400mm and two at 300mm, with my new Canon 100-400mm mark ii lens and there was virtually ZERO difference between the shots with vs without the 1.4 - it was impressive! I'll let you decide which ones are which. I showed a friend the shots and he couldn't pick the ones taken with the 1.4 vs without. IF there is a difference, you must have done some scientific study. That or its nothing a little post sharpening wont fix in short order. Auto focus works just fine. Its a TAD BIT slower with the converter, but not that you'd ever really notice. It is still pretty fast. And you only get f8 at 400mm. Cant go any bigger. If you want f7.1 then you gotta zoom back to around 300mm. this may or may not depend on what lens you are using as well. I recommend this unit to anyone looking to get more reach without looking to break the bank. I see virtually no image degradation across several focal lengths and several fstops. I paid 380 for mine brand new. A used one would be an even better deal. The Coke can images were untouched. Other than cropping them to size and putting the 4 of them together into one image. NO editing was done to any of them. They are all straight out of the camera. Read full review

A little Disappointed
I bought a 400mm prime lens a few months ago, with which I could get much sharper images than I got with my 75-300mm zoom or my super-zoom camera. I missed the reach (1200) that I got with the super-zoom, so after some research, I bought this extender. Unfortunately, I haven't been as pleased with the image quality as I expected. There seems to be a bubble in the glass, but I bought this used, so I'm stuck with it. I don't know if the bubble affects image quality.

Sharper than the also excellent 1.4x II model
I've used Canon 1.4x II extenders with my L series lenses for about 15 years. They've delivered everything you'd expect from Canon's pro line lenses. After reading reviews of the type III, I decided to buy a 1.4x III to pair with my 100-400mm ISII lens. On receiving it, I shot some test photos under controlled conditions with the 100-400mm/1.4x II and 100-400mm/1.4x III combos. While both were very good, there was a noticeable difference in sharpness with the 1.4x III. If you have an ISII L-series lens, and you're interested in adding some versatility to your kit in a relatively inexpensive, compact and lightweight package, you should definitely consider this.

Great Accessory for Long EF Glass
I purchased this to accompany an also-purchased EF 300mm f/2.8 II. I found that I prefer the 300mm focal length for sports over a 400, but want to make sure I have my basics covered. The total cost of the lens and extender was still far less than purchasing a similar condition EF 400mm f2.8 II or III, let alone an RF 400mm f/2.8! I don’t see any difference in IQ on my R bodies with an adapter. Highly recommend!!

its great with some lens not really good with others even with practice however if one can pay for it it would be ok to own -- borrow or rent one first -- be sure it is in the type of use for you or disappointment will follow ,, i still like it for a few things... will not resell it ,, thanx for reading my2cents
