Pros:Quality of materials; Rendering of immagins up to its focal point; Tropicalized; Lightweight; Size; Autofocus speed
Cons:It's no use... at least with my Canon 70-200mm F4 L IS USM
Opinion:Well done, definitely worthy of being an L series, but beyond its focal point, it loses enormously details. When I tried to take two photos keeping the same settings of the machine, both at 200mm without multiplier, and at 280mm with multiplier, then making the magnifications until it reached the same size, the photo taken without multiplier was sharper than that taken with the multiplier. I don't know if it behaves the same on other targets, but on the Canon 70-200mm F4 L IS USM. I initially put it up for sale, but then in doubt that the problem arises with all the lenses, I preferred to return it to the store
Pros:All in the truest sense of the word I think in Canon they have overcome themselves.
Cons:Maybe the cost a high hair but the quality you pay
Opinion:I use it paired with the Canon 100-400 is ii and I have to say that it is phenomenal both from a quality and quality point of view af. Also tried on 500 f4 and 600 always Canon and goes great. From what I've heard and read a little bit around you say it's not so punchy on non-series optics L waved Competing Brands.
Pros:small and light, with the right lenses it works great
Cons:with some lenses goes slow but does its duty, perhaps too expensive.
Opinion:Tried with the canon 70-200 II 2.8 on 1dx II to photograph the bikes on the track and I was very satisfied. It is true that you go from f2.8 to f4 but the speed of the shot remains practically unchanged while on the canon 300 f4 is you lose here a stop (who cares) but the speed of the shot drops a lot and you notice the difference however the work in the end I brought it home with the latter because despite going slower than the 70-200, in the burst shot was still accurate and reliable. really satisfied. I did not do a careful analysis but the photos came out well are to my eye as sharp as those without and I did not feel any loss of quality (I repeat I did not do a micropixel analysis !)

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
Pros:Sturdy, weather sealed and auto-focus speed virtually unchanged. Fabulous color rendering.
Cons:As always, the price, unfortunately Canon has raised the price lists in an exaggerated way.
Opinion:Personally I almost always mounted on the old Canon 300mm F2, 8 L USM dell 'year 1999 (to be clear Not Stabilized version) rnrnTrovo imperceptible slowing dell'autofocusa and with an amazing quality to the photograph of birdlife in my humble opinion if they can not 'do without. Defects honestly I've never encountered. rnrn I would certainly recommend, eye caps because they differ in size from the previous .........
Pros:Great level building, gaskets, good optical performance, quality of materials and finish, lens aberration corrections on DPP.
Cons:price is not exactly cheap.
Opinion:In the past I used a multiplier that Sigma is no longer compatible with the latest optical canon, so I adopted the Canon 1.4x III series. I happily found that no cartoon, maintains good optical quality with a final decay very content of the image on EF 200 f2.8 L and EF 70-200 f4 L is the camera and 1D MkIII. What impressed me most is the quality of construction, the materials used and the level of finish of the machined bayonet Eph. The autofocus is fast overall except for some rare situation with reflective objects. Using it on 1DMk3, 50D and 1Dmk2 data communication between camera and lens + multiplier is excellent. Ultimately an excellent multiplier that saves weight and offers the flexibility of two focal perfectly usable.
Opinion:It certainly is not given but I find it a good way to stretch the mm and light weight while maintaining good image quality. RnLo use the 70-200 f4 L IS (280mm f5.6 where it maintains the exceptional quality of the lens is not multiplied in all openings) and the 300 f4 L IS (420mm f5.6 with a minimum decline of sharpness but it is still a great way to have a good telephoto 400mm light and "cheap").
Cons:High price, not light, reduction of 1 stop of brightness, which is not compatible with all lenses
Opinion:Very practical to increase the range of focal lengths available to us with a relative weight, excellent optical quality with very little loss of sharpness especially on some lenses such as the 70-200 and 17 tse, ac and negligible distortion, it works best in the center and the fall of light and sharpness of the edges and 'very low; autofocus is fast and effective, highly recommended for those who want to travel light.
Cons:- Maybe the price! It 'still a 2x multiplier when combined with optical jumps off a series of L, (
Opinion:Not having previously owned the Series II, which many feel was not so 'bad, I launched this multiplier new generation, at first blush compact and very light. I tested it only on the 300 2.8 i have to say is that it involves super good aberrations and vignetting it any other disease, the AF is fast and accurate, the combined use of a 1D mark III, tropicalization there 'and the present seal is demonstrated in full, I can only recommend it! cost € 440.00
