Pros:Quality, lightness
Cons:Nothing, maybe the price but worth every penny that costs
Opinion:The ideal playmate for Canon telephoto lenses, excellent yield both with 70-200 f/2.8 and above all with the 100-400 is II, especially because it allows the focus with all points at F/8 on the 5d Mark IV... maintains a very good speed of focus and loses very little from Point of view of the sharpness, sure Canon does not give it to you but for me it is a must buy
Pros:Constructive levels from series L, nnitid, lightweight
Cons:Maybe the price ....
Opinion:Purchased mainly for use on the 100-400 IIrnin as the Kenko name does not work and the Canon 2x iii loses the automatisms. RnrnThough crisp and responsive despite stealing a stop on the openings, so far it does not seem to be mounted. The price is a bit excessive, but in the end you have a great and working product ... rnWarned where '2x iii does not work.
Pros:Image quality, speed and precision of AF, construction, tropicalized
Cons:Not usable on 100 L is macro
Opinion:At 5d3 and 100 400 mk2 at 400mm the maximum aperture becomes f8 (one loses one) but the QI remains practically unchanged: it is as if it was not mounted. Even the AF performance is unchanged, although only 5d3 remains active with the 4th expansion point. I also have the Kenko Pro 300 DGX 1.4x that I paid one-third of Canon and on 5d3 with 100 400 mkII all the AF points can still be used, but it is slightly affected by the speed. IQ remains excellent even with Kenko and genuinely I can not say if Canon 1.4 III is better in this regard because they are both great. In general, what impressed me with the Canon series III is that the AF speed performance remains substantially unchanged, as if the multiplier was not there. RnA major flaw is that it does not work with the Canon 100 L is a macro that works correctly with the Kenko 1.4; Is an obvious choice of Canon marketing to keep your feet at 180 L macro. From a constructive point of view, sEnsura is really great: Kenko is much heavier than a much more plastic feel. In addition, with the Canon 1.4 III mounted, the tropicalization of the system is maintained.
Pros:Definitely improved over the previous version. Able to maintain almost unchanged is the AF speed that the optical quality on which it is equipped.
Cons:Nobody. Having previously used the version II I can not see.
Opinion:6ugrave; light of the new version that made me feel more fragile. But in fact it is not, it has nothing to envy to the previous version. rnrnHo got to try on the Canon EF 500mm f / 4 L IS II USM with the 5D SR (amazing) and with the 1D MK IV with which to my mind keeps all its peculiarities, even if the camera body and its AF module it is a bit less young, on this last camera I also used with the 200mm f / 2.8 L II USM with considerable satisfaction both yield and velocity AF (basically I have not noticed his presence) when used with optical not the latest generation mistakenly thought the quality was worse, and even here I had happily ricredermi.rnIn substance in my opinion the new teleconverter 1.4x III has made great strides in quality to the point that if the first ' use of the version II was somewhat a stopgap to not lose the picture of a distant subject provided you give up a little bit of quality; Now the quality that returns the new version 1.4x III is directly comparable to the smooth optics on which montato.rnIl price seems adequate for what it is able to return, is a totally professional tool that can easily become indispensable.
Pros:no one else will have been a technical evolution from the first extender Canon Ii opinions are very divided and heterogeneous
Cons:price and I think compatibility if you do not have goals canon largemouth
Opinion:I own the first type I with a Canon Extender 70/200 f 4 IS always stabilized Canon and Canon 400mm f 5,6ho also multipliers Kenko Pro 1.4 and 2 300 DGXvale is worth selling the extender Canon I? and then you need to buy a new one for my lenses? or advantage is irrelevant? rnho noticed that on my 400 my Extender does not work well ..autofocus slow .. .drivetrain data ... rnmentre on 70/200 if the cavarni Kenko maintain automation and are fast nell'autofocusrnil decay of image however enough notevolernora I have a new body 5D Mark III and for this I make these questions
