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.

Pros: Value for money, keeps EXIF data

Cons: For what it costs nothing

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.

Pros: excellent value for money

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.

Pros: Sharpness from the center to the edges substantially comparable to a lens not multiplied, compatibility with Canon optics not multipliable with the original, light and compact, excellent quality / price ratio, you lose one stop of light.

Cons: Lightweight lens mounted on the multiplier game but I do not think this affects in any way the performance, slight decrease in AF performance especially at the level of engagement speeds in low light, non-tropical conditions.

Opinion: Excellent 1.4 multiplier purchased at EUR 150. Excellent value for money. I purchased it for use mainly on the 100 L macro is because the original of this lens does not work, the results are spectacular because lengthening the focal, improves especially the blurred backgrounds that is more homogeneous; the image quality is similar to that produced by the objective not multiplied and also the colors remain unchanged. I tried it, and also used on other optics: 70 200 100 400 f4 L and L is mkII. In particular, on the latter goal, in theory, the Kenko Pro 300 DGX 1.4x coupled to 5dmk3 should not work; in fact, my original works perfectly even with the 100,400 L is mkII and the AF is always responsive and accurate, even for the birds, except in low light where it is more difficult. I recommend it especially to those who have the 100 L is macro.

Pros: Compatibility with goals not multipliable with the originals and optical performance.

Cons: Lack of tropicalizzazone

Opinion: I took this multiplier for use with the optical that would not multipliable with the original equivalents. The optical performance is quite good, I think it would be difficult to notice differences in the practical use with the originale.rnL'ho counterpart also used in combination with Canon EF2X series 2 with excellent results. rnConsigliato but conscious compatibility with new bodies Canon.rnrn machine

Pros: quality, cost, versatility

Cons: Touch does not seem very sturdy

Opinion: I'm satisfied with this multiplier. I use it with telephoto zoom Nikon 70-200 f / 2.8 vr2 and sometimes with the 300 f / 2.8 to f and I must say that the image quality, even falls compared to the use of these straight goals, is always good and usabilissima . I tried the manual and the tc 14 tc 14 eii and, to tell the truth, I have not felt better photo quality and also the tc eii, as the current successor, can only be used with afs objectives while kenko eat virtually everything from manuals, to af and to afs. It does not seem to see it at the top of solidity but also with the 300 2.8 can be used without problems. last but not least because the very advantageous price, both new that used, for a multiplier that does its job and does it in great way.

Pros: Cost

Cons: sharp decline, increased aberrations, decrease AF performance beyond legal

Opinion: I gave 4 vote, I am quite disappointed, I hope it is a problem of my copy, used with the 6D and the Tamron 70-200 2.8 the sharp decline seems to me excessive to try all openings (4 to 16), the AF He finds it hard to keep up even in good light, known widespread chromatic aberrations. rnCerto cheap, not having tried the canon can not do against money rn

Cons: malfunction with Canon 100 2.8 L IS Macro

Opinion: HELP HELP: malfunction coupled canon 100 2.8 L IS macro and kenko TELEPLUS pro GDX 1.4 x 300 with Canon 70D. By mounting the coupled macchna on, the camera freezes. No longer work the controls, the autofocus and exposure.

Pros: Good image rendering, robust build quality more than proportionate to the price, AF responsive and secure, lightweight.

Cons: It is not weather sealed; the body does not have the quality of Canon lenses (white series).

Opinion: Opinion: This afternoon after just two days after ordering, I got the two multipliers of Kenko (1.4x and 2x DGX PRO 300). after some test shots (5D Mk III and EF 200 f2.8 L) first impressions are positive. I state that I can not make any comparison with other multipliers, but only a comparison of the quality and the speed of AF, with and without. In principle, there is no sensation or degradation of the difficulties in the use of AF. Use in cascade (1.4 + 2) AF had some uncertainty about just "subjects" special. I am referring to white clouds and dark areas heavily (in the evening). As soon as he returns to the 1.4 or 2, you do not feel even the uncertainties in the AF. The picture quality is about the same. Obvious that losing one or two stop the effect will be different from f2.8 bouquet. Let us also that the light passes through an additional group of lenses. On balance "the game worth the candle!" For the record with the 1.4x from f2.8 to f4 switches; while with the 2x f2.8 you passin at f5.6; both (1.4x and 2x) moves from f2.8 to f8. On the 5D Mk III AF problems whatsoever, whether individually mounted is fast and has no uncertainty!

Pros: Small, economical, compatible with objectives not multipliable, good quality

Cons: Not compatible with EF-S lenses

Opinion: I use it occasionally for a year, on a Eos 60D coupled to the VC Tamron 90 Macro or the Tamron 70-300 70-300 VC.rnCon the point of central focus stops working with focal lengths over 200mm, but remain active side. In general, the quality is not much worse, with the exception of a higher chromatic aberration. In particular, the 90 macro, I struggle to see differences in the definition. rnNon I noticed great delays in focus, only a few "indecision" in più.rnPurtroppo does not seem compatible with my EF-S 15-85. This is the only flaw I find in this perspective on the relationship price / quality layer.

Pros: Excellent quality / price ratio. Only alternative for Nikon AF lenses and AF-D ... compatible with both mechanical autofocus (has the PTO) and electrically.

Cons: Construction "economic"

Opinion: Excellent quality / price ratio ... costs half compared eponymous Nikon ... maintaining excellent quality and especially the only compatible with both Nikon optics (or Sigma) AF and AF-D thanks to the PTO of mechanical 'autofocus. It also has all the electric and electronic contacts x be also compatible with AF-S lenses. Correctly detected in the data exif shooting. I use it with satisfaction on Nikon AF 300f4 and Sigma AF-D macro 400f5,6 slowing but keeping the autofocus. Consigliato.rnPs: rnPiccola known ... Sigma 300mm f2.8 EX DG HSM and Tamron 150 ~ 600 x Nikon both the TC in question does NOT work.

Pros: Optical performance, cost

Cons: Compatibility Nikon's VR?

Opinion: With Nikkor 300mm f4 AF-s must be a marvel, with Nikkor 70-200 VR II stabilizer works but the noise is greatly amplified compared to the use without teleconverter; wondered lights of this e-mail to the parent, the answer was that the TC is not compatible with Nikon's VR and therefore would be better to turn it off ... rnCerto if that is really so, they could also report it somewhere, right? rn

Pros: Lenses of excellent quality and no vignetting. Fast autofocus with optical motorizzate.rnPrezzo competitive and good mechanical construction.

Cons: At the moment I have not found.

Opinion: It 'a good accessory that I tried it with my D90 and the Nikon AFs 35 and 18-70 1.8 3.5 / 4.5 but above all with the 105 afd, which is actually intended. Excellent yield with the macro and even with the zoom, while with the 35 I have to diaphragm least 1.5 or 2 stop. The overall contrast is lowered slightly as the colors remain faithful. To recommend a purchase.

Pros: Hoya lenses of excellent quality, no vignetting, the Auto focus in good light conditions remain acceptable retains EXIF ??data

Cons: In my opinion no, it is clear that if you apply a multiplier a slight loss on the performance of the lens we have to be.

Opinion: I use it on a Canon EOS 550D paired with the Canon EF-100 2.8 macro or the Tamron 70-300 4-5.6 Di VC USD, with both lenses behaves well. E 'consists of high-quality lenses, then you will get very good shots. But you have to take into account some precautions when using it because some light is lost, if it is used during the day with the sun, it is not a problem, it keeps the AF although close to F9-10, but with the sunset would use the MF and in some cases even a tripod. With the 70-300 a bit of speed and accuracy sull'AF you hear. These are not critical to this fantasico multiplier that buy back 100 times. With the canon 100 2.8 macro the problem does not feel as it becomes a 140mm F4 and remains a beautiful opening. In the end you have to be careful as not all lenses are compatible. That said I think this is a real giogliello.

Pros: Cheap, good yield, do not lose AF on bodies canon "not" series also above 1 f / 8

Cons: not received

Opinion: A multiplier as very good quality and sold at a good price, it has the huge advantage of AF also operate on the bodies Canon 1 series is not even at f / 8 and up, but there is also saying that AF slows down and from f / 8 and up into scenes of shade could not hook but if you want millimeters and do not own a Canon 1 series this multiplier for you

Pros: Price (new paid the equivalent of 134 euro to hong kong), exif data, lightness, performance of fixed lenses exceptional, personally I have not found any limitations on the use of diaphragms lens except the obvious loss of two stops of light.

Cons: With zoom lenses AF becomes difficult light conditions difficult, not weather sealed

Opinion: Tested on the Canon 70-200L f4, 100-400L, 50 f1, 8, 100L macro and I carried out all tests in the studio on APSC sensor (Canon 60D). Result 100-400 of staff is preferable to crop the file with objective smooth as it keeps more details. With the multiplier is much softer than it already is. The 70-200 I have not found notable differences on fixed while I find it just brilliant, if used to amplify a 40% macro capability helps capture a greater amount of detail and the 50ino 1.8 seems to give him even sharper turning it into a 70mm f2, 5.rnFunziona even in cascade with the extension tubes. From HAVE! RnConsigliatissimo on fixed and very very helpful with macro.rn

Pros: Yield optics, price

Cons: Construction optics

Opinion: Taken primarily to match the Canon 100 L macro, I used the Canon 300 f / 2,8 L IS. The AF is fast and powerful and I can not fault dips or baked sharpness file from my 7D. Compared with multipliers Canon (version III) found it very plasticky and not sealed, but costs still less than half.

Pros: Cheaper than the originals (paid 150 €), good construction, compatible with a lot of optics, excellent optical quality, no compromise on speed precision AF, EXIF ??data successfully transmitted.

Cons: I have not yet found

Opinion: I got to use it on D90 with 300 f / 4 AFS (since the original is too expensive for me and is not used) and can not seem to get it, it was not for the fact that the maximum aperture is f/5.6 and no longer f/4.rnL 'f is precise and responsive as ever, even in low light, the EXIF ??data is transmitted to perfection, the optical quality has not been sensitive to even worse comparing two crop at 100%, no trace of aberrations cromatiche.rnProvato also on the 105 f / 4 with excellent micro risultati.rnHo focheggia found that without too much trouble even at f / 8, f/5.6 lens trying it with the one that I possess the 18-105 vr nikon@105mm.rnUn 'good product, would recommend to my eyes closed to all those who are unwilling to spend € 400 for tc14e original or have optics that are not compatible with this multiplier.

Pros: auto focus works to f8 as the series of canon 1d 30/40/50/60/7/5

Cons: no one gave the advantage of autofocus

Opinion: I had the canon tc 1.4 mk1 and mk2. I then tried the 1.4 sigma dg dg and not everyone with the damn tape on the first 3 contacts "was an annoying scocciutura" I use both the 70-400L and 200L and on about the speed of the AF does not decrease is as if were smooth. Use a eos 50d and confirm that AF f8 "WORK" without tape. I think the canon and sigma should cost half compared to the kenko. about the quality of the lenses. . . say that up to 18-20 feet away you do not notice a loss of tettaglio.

Pros: Economic (new paid 176 euro) - QI good-Mounts all optical unlike the Canon-Maintains autofocus to F 8

Cons: Building a little plasticky-not-tropicalized a little vignette

Opinion: Use this extender combined with the EOS 5D Mark III + 400 5.6 and I'm strasoddisfatto, autofocus works on all points even af ??8 without hesitation and is accurate (practically the same performance as never 7D + 400 5.6 smooth) . Fast in pursuit, I did not expect performance like that. In my gallery you can see some examples. The negative notes (negligible) concern the vignetting (eliminated by slight crop) and a dash of lateral chromatic aberration on the strong contrasts of light. Ultimately very good in the center to the edges. I highly recommend it for good money.

Pros: Value for money (c.a. 195 euros) , finishing, lightness, perfect communication between reflex and optics, the ability to maintain the af with reflex aps-c to f.8 (t.a.) with apsH and FF with some individual points that vary between reflex and reflex. It has a yield very close to the canon 1.4x series II - 3 peculiarities in the field pairing The Kenko 1.4x PRO 300 DGX with macro optics 90mm up: a) at the same distance the subject will take up more space in the scene - b) at the same magnification will recover from further afield disturbing less a living subject or away from the possibility of shade the subject - c) maintaining the af at any distance

Cons: it's not tropicalized

Opinion: Tried with optics such as canon 70-200mm f.4 l is usm , canon 300mm f.4 and f.2.8 L is usm, canon 100-400mm L is usm (on aps-h), 400mm f.4 is DO : the overall loss of sharpness is not noteworthy. I've used it often with the 70-200mm turning it into a 98-280mm to f.5.6. I now use it by default with the canon 100mm macro L is usm f.2.8 and is a winning pair that turns the optics into a 140mm is ... even here if there is a leak is not perceptible.

Pros: Price, possibility to put in cascade with other multipliers thanks to the absence of protruding parts (see for example the original nikon), loss of sharpness imperceptible closing soon as the diaphragm, possibility to use it also with old lenses mechanical (ie not AF-S) .

Cons: mechanical play present already after a short period of use, but nothing incriminating for the structural integrity of the body + lens + multiplier.

Opinion: An excellent compromise for those who do not want to spend much and for those who need to multiply old lenses do not AF-S (such as macro 60 2.8 / D or 80-200 2.8 / D or 300/2.8D AF). Clearly has excellent performance even with modern AF-S and I think the fall of sharpness compared to an original nikon (with which I compared it) is irrelevant. I have not encountered any loss of precision of focus, that was not already due to the loss of brightness by the multiplication factor. Recommended!

Pros: elemnti not protruding, from wide-angle to tele usabilissimo driven with maximum aperture of f4 or 5.6 per transmission exif bodies if the focal length as well as the diaphragm price

Cons: I can not find, but I use it as little

Opinion: I tried it with the 16-35L canon with the canon 50 1.4, with the 70-200L Canon, Tamron 90mm macro, Canon 28-70L I have not found any problem, no chromatic aberration (maybe a little with the tamron, but this is a little too smooth, but the canon does not exist smooth and even multiplied) its strong point is right here, you can assemble with all the goals fixed or zoom, wide-angle or telephoto, the loss is almost non-existent, a really nice product and I am amazed at the accuracy of the exif for both the focal derived for the opening .. the first, 4x will not regret the various canon if you wish to use it just where these can not be used .. on FF then gave his multiplication factor is like having a aps-c, you can always leave wanting mounted in situations of increased risk dust vosrti web surfing changed the objectives, it will feel a little and you will be much more protected, I think you can call a MUST -HAVE

Pros: Optical quality, construction, EXIF ??data

Cons: Slow autofocus

Opinion: I use it often combined with the Nikkor 300mm f / 4 and the Sigma 150mm f/2.8. In terms of sharpness and chromatic aberration is not known significant worsening compared to only one goal. The construction is very solid and the idea of ??a very well done. Very convenient that the Exif data is transmitted correctly. The autofocus loses much in sensitivity and accuracy, but do not know if this is due to the goals that I use that are not certain of the samples in this field.
