When used with a 70-200 f4L IS, it gives me an equivalent: 98-280mm and f5.6 - f45 aperture.
When used with the 70-200 F4L IS and an EOS 7D you get approximately: 157-448mm and same aperture.
I'll try to post some picture examples above for the product description because "they" won't let us put links here. :-(
PROS: Extends the length of professional quality Canon L Lenses with little or no noticable degredation in image quality.
COS: Only works with certain Canon and 3rd party lenses. Some of the 3rd party teleconverters such as Sigma and Tamron will work with other lenses that this TC will not because of the protruding element but I just can't beleive they are as good of quality. If you are ONLY using this with the compatible Canon lenses, then get this one definitely.
YOU MUST CHECK THE COMPATABILITY CHART BEFORE PURCHASING THIS SO YOU ARE NOT WASTING YOUR TIME. As of 4/29/13, this is what Canon's website states: Note: This lens is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L.
Sharpness wise, the 1.4x III is better. I compared carefully doing side by side test shots... Tripod, mirror lockup, live-view focus, etc... The 1.4x III always had finer detail and more contrast. It was actually quite noticeable, although not as much in real-world shooting. AF performance is the same (with this lens), but I do like the build quality better. More mounting screws, better switch to release the lens, etc...
I think it was worth the upgrade after seeing the additional resolution it offers. I am very happy with it.
It stands to reason that an extender at a few hundred pounds cannot possibly do anything like the job of a longer lens costing thousands of pounds.
If it did then Canon would soon be out of business!
So exactly what is on offer here and what is not?
A considered and truthful opinion from a professional photographer and his supplier.
Not everyone will be bothered by these professional provisos but everyone should understand the issues before considering purchase as follows:
Firstly the hard facts:
1. This extender loses one stop of light which means that only 1/2 of the normal light from the lens will reach the sensor
2. Only series 1 cameras will only give auto focus at basic f8.0 or wider which means that the slowest lens possible for auto focus will be f5.6
3. Non-series 1 cameras will only give auto focus at basic f5.6 or wider which means that the slowest lens possible for auto focus will be f4.0
4. Both the f4.0 or f5.6 basic apertures with the extender fitted will increasingly be relatively slow to latch on to focus in less than good light
[...] gives in-depth reviews of all lenses and full explanations of the above facts.
My professional experience
This extender was bought primarily to extend the use of the 300mm F2.8 and the 70-200mm F.8 lenses. I had previously owned the original version of this extender and then the Mark 2. This Mark 3 continues the improvement although it must be said that differences are slight and you need large images to fully see any real change. All three extenders have real matters of compromise to consider and these apply to this latest model too.Read more ›

Very well built. Works well with the lenses it was designed for. It works well on Canon EOS 6D and 7DII. It is very expense compared to third party Extenders.Published 2 months ago by Amazon Customer
