Opinion:A little gem to always have with you. Used in conjunction with the Canon EF 70-200 f / 4 is L series and especially for over 4 years with the Canon EF 100-400 is II L series, with the "old" SLR has always behaved very well, practically I have never noticed loss of sharpness. On the other hand, with an R6, always with the same lens, I could find a slight "fogging" of the image when mounted. I sold it together with the above optics opting for the native RF 100-500 that I intend to use without multipliers to the advantage of sharpness and greater aperture (f / 7.1 instead of f / 8) at the small cost of a very modest loss of mm (500 instead of 560). In summary, recommended on SLRs!!!
Pros:When used with the right optics, camera and light conditions, it doubles the focal length without significant loss of optical quality and AF.
Cons:Subject to the above, nothing.
Opinion:I use it to "double" my EF 500 L f4 IS III. I find it great (read the pros and cons) for what it allows me to do when the distance becomes prohibitive for the lens. Together with the little brother 1.4x is fixed in the backpack that houses the equipment that I carry in the circuits. Not to be used, of course, in the presence of strong rises of hot air where the bad result would be attributed to the photographer and not to the combination lens + dupli...;-))
Opinion:Tested with 7D MK2 and 100-400 II Identical light conditions, shooting with and without multiplier Images without duplicator have always been slightly better (sharper) , despite the greater crop of photos without multiplier. So it is useless and therefore unusable. I don't understand the many enthusiastic comments.

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.
