Pros:Construction. AF and stabilizer unchanged. Sharpness unchanged. Price.
Cons:Must there be a counter?
Opinion:Between Canon 6d and Canon EF 100mm f/2.8 L Macro IS USM: Sturdy, not wobs at all as some say, immediate AF, stabilizer OK. Sharpness unchanged. So how not to have it, just that you find yourself with a 1.40 mm x. On fixed optics from 50 mm up and on the zoom from 24 mm up where Canon Extender is not compatible. I forgot: Price half of the Canon extenders. I can't wait to try it on Zeiss ZE Apo sonnar T * 135mm F/2. P.S. tried: A 189 mm monstrous!
Pros:It works with the Sigma 500 EX F/4.5. It focuses in outdoor even over at f/11
Cons:Slightly soft
Opinion:Tried with Nikon D750 + Sigma 500 EX f/4.5. All the automations work. It is preferable to use it with the tripod and absolutely use a button for the shot, so as not to move the lens, because since it softens the photo slightly (like almost all teleconverters) if we add the micro moved then the photo is to throw. While if used as I explained the photos remain good. Almost precise coupling, remains a slight slack once hooked to the camera body but I have not found defects in the photos. The autofocus works pretty well, being not very fast that the Sigma does not notice the live performance decrease. Excellent product and at an honest cost. A greeting
Pros:Robustness, maintains the automation, compatible with Canon lenses more than the original, cost
Cons:Nothing special
Opinion:The multiplier is done well and does not introduce obvious quality drops if you close the smooth lens of one or two diaphragms (at TA I see the difference). I do not use it very much but given the price and yield makes me very comfortable on some occasions, I use it exclusively with the Canon 70-200 F4. Autofocus and Automations maintained perfectly. Recommended.
Opinion:I use very little and it is the second time I purchase it, my focal range goes from 35 to 135 so I use it once a century right on the 135, that time that 135mm is not enough. The occasional use would not justify the purchase of an expensive duplicator, nor that of a 200mm f2.8. For such a described use I think it's the best. The quality is, all in all, good. It is difficult to compare "with" and "without" duplicator because the focal of course changes, the sharpness seems almost the same, maybe some slight indecision to 100% but small indeed. I know that with 2x things change dramatically with the 135mm but with 1.4 x on both the 135/2 and the 200/2.8 (which I have not but I could try) is very good. Especially recommended for fixed objectives and within the limits of use described above. I recently discovered that on 6d2 it does not work, it crashes the machine even.
Cons:it works with many canon optics, where the official canon duplicator can not even be mounted.
Opinion:bought for trial on Canon macro 100L since the original canon is not supported. For a stop on any optics that is mounted. rnrnA large amazement and satisfaction I found that the canon optics that I "digest" are many .... rn I had to test it with canon 6d and 80d, then a ff and apsc and optics comern16-35 L f 2 8 II Usmrn24-70 L f 2.8 II usm rn70-200 L f 2.8 II usmrn100 L f 2.8 macro Lrn35 f 1.4 (Sigma) Unfortunately, the Canon 100-400 II does not recognize it.

Personally, I would recommend it to those who would "try" or multiply their optics without spending crazy figures for an original canon. rnrn
