I have used this both my trusty D700 (FX format) and my older D200 (DX format), principally with the 28-300mm f/3.5-5.6G ED VR lens Nikon AF-S NIKKOR 28-300mm f/3.5-5.6G ED VR Lens, and this combination is genuinely usable on both cameras. The electronic coupling between lens and camera works correctly, with the camera "seeing" the modified focal length and aperture, and the VR function of the lens works correctly too. That is a "G"(elded) lens with no aperture ring so information is transmitted digitally, but this converter also has the necessary mechanical coupling to transmit manual aperture settings from older lenses to cameras using the old N-AI fitting,in other words it works with my pre-digital lenses too.A 1.4x converter loses 1 stop of light, so auto-focus works pretty reliably on that lens up to about 250mm focal length (on the lens), but between 250 and 300mm you need good light and a reasonably contrasty subject for it to work properly. This seems especially true for distances near infinity where the camera can sometimes just give up making manual focusing necessary, but for closer subjects it seems pretty reliable. It is slower than with the lens on its own, and prone to hunt a bit in lower light, but for the most part perfectly usable.Image quality is good: definitely better than using the lens without a converter and magnifying digitally by 1.4x, which is after all the point of using a converter. No, it's probably not quite as good as a lens with the "true" focal length, but you pays your money and you takes your choice!Build quality is a bit "plasticy", especially when compared with my old (pre-digital) TC200 Nikkor converter, but good enough unless you plan to bash in tent pegs or the like with the camera. Others have complained about a slightly sloppy fit, but on my cameras and lenses it seems tight enough. It's quite slim, and when fitted you don't really notice that it is there.A slight digression about 1.4x versus 2.0x converters, but hopefully helpful to some readers.I also have the more powerful 2.0x version of this converter Kenko Teleplus DG Pro-300 2X Nikon Teleconverter, which is optically good but which necessarily loses 2 stops of light. This means that the sort of zoom lenses I can afford, which are typically f5.6 or slower at the long end of their range, quite quickly drop below the f8 or so aperture threshold at which auto-focus ceases to work. For example the 2x converter fails to auto-focus on the 28 - 300 lens mentioned above much beyond 180mm focal length, which means that it actually has *less* useful range than the 1.4x converter plus that lens for situations where I need auto-focus, as well as being 1 stop slower.So if you are dithering about whether to buy the 1.4x or the 2.0x times version and, like me, you can't afford the faster aperture long lenses, my advice is this: if magnification is important and you are happy to use manual focus (and possibly a tripod) then go for the 2x version, but if you will be working hand-held and your subject is fast-moving then stick with the 1.4x since it is much easier to use.A final point: just for fun I stuck the 1.4x and 2.0x converters in series (so a theoretical 2.8x magnification). Total disaster with the modern "G" lens since it seemed to lose the ability to transmit information electronically between camera and lens, which remained stuck at f22, so the result was unusable. However with an older mechanical lens it worked just fine, although the viewfinder becomes pretty dark which makes focusing a bit of a challenge. So if you want 3x magnification on a modern lens you'll have to buy a 3x converter. (Kenko do one, but it's not on Amazon).

I have tried this converter with two lenses: First, with Nikon 18-200 VRII lens, it works at all focal lengths just fine. Second, with Sigma 50-500 it works fine at all focal length, but only if there is enough light. Once the light goes down, you will lose autofocus. My eyes, and expertise, are not good enough to tell you if the metering works OK, or not (but if you read the reviews, they say it does). Couple of other points - when not mounted, if you shake there is a rattling sound from it. This seems to be the way it is built and the rattling sound comes from some sort of coupler (experts will say what sort that is). However once mounted, no sound comes no matter how much you shake it.

First some factsTeleconverters:- will emphasise any defects in the lens the are attached to - image quality is guaranteed to reduce. Full stop.- usually remove x2 f-stops from the lens they are attached to.- In the case of this product .... it WILL NOT auto focus at the attached lenses longest focal length. Be prepared for manual or not auto focussing to infinity (Canon 70-300mm IS)With the above in mind, you have to ask yourself why you are going to consider buying a teleconverter. Surely the ONLY valid reason is cost. IF you can afford a more powerful prime/zoom lens then DO NOT waste money on a teleconverter. Do your research and invest. HOWEVER,

I purchased this Kenko 1.4 converter mainly for my Sigma 150mm macro lens to get a bit more working distance for my insect macro photography.I works quite well with very little loss in image quality, certainly not noticable to the casual observer.It does give a little more magnification when working at closest working distance too but it can make handheld macro photography a little more difficult because camera movement is exagerated a little more and depth of field becomes even less, but results are quite acceptable.I also use it on my Nikon f2.8 80-200mm lens for a little extra reach should I need it when I don't want to carry a bigger lens.It should be remembered that when you attach a converter to a lens a stop of light is lost automatically on the camera,

I got this after reading a lot of write-ups on the web. It has lived up to expectations, creating little loss of quality on a 400 f5.6L. Possibly a slight increase in CA but nothing bad at all, and only really in high contrast highlight areas. It allows AF to function surprisingly well with this lens on a 7D (technically it shouldn't happen - f8 effective) BUT not with the centre point or the ones around it. AF has to be performed with the outer points (i should point out here that with an f4 lens it will be fine on all AF points). Tbh it's not a major issue when you get used to it and can even aid composition with some shots! AF accuracy is OK in good light,

I was replacing a 70-300mm f4-5.6 IS lens with a 700-200mm f4 L lens. The main aim was to get better quality and faster glass. The downside was always going to be the loss of the zoom range at the longer end. To mitigate this I bought the 1.4x converter to get me to 280mm at the long end. As I only occasionally need the longer end of the zoom range, I wasn't too bothered about getting the best quality (otherwise I would have bought a longer lens or Canon's own teleconverter). This is an excellent compromise on price vs quality. Just beware that you will need a lens that opens up to f4 or wider in order to get the auto focus to work on the Canon bodies - this is because the 1.4x convertor adds an extra stop,

One hears a lot of noise about how good / indifferent / poor tele converters are; particularly 3rd party teleconverters.In my case, on a Nikon D300 and 7200 and with Nikon lenses this Kenko converter functions perfectly.Autofocus is pretty much as fast as it ever was, and all functions work correctly. A 300mm f4 lens becomes a 420 f5.6 and helps fill the frame with the subject.If you spend all day every day taking pictures of brick walls and the like, you may notice increased softness at the corner of the frame, though less on an APS-C sensor than an FX sensor.If you don't and you're more into portraits or wildlife, I doubt whether you'll notice the softness, and even if you do,

I have a Canon 70-300 mm IS USB lens which is superb and expensive but will not mate with Canon's 1.4 extender. However, The Kenko MC 1.4 Konveter does the job very well. There maybe a very small loss of quality but this is not noticable. The Kenco extender is something like half the price of the Canon equivalent which does not work anyway. By purchasing this gadget and using with the aformentioned Canon 70-300mm lens you get a 420 mm lens with very acceptable quality. The aperture reduces to F8 at full extension which means that the shutter speed also reduces for the same result. In turn, this results in the need for bright conditions to obtain good pictures. However, as always,

The kenco 1.4 teleplus pro 300 DGX fitted to my canon 7D works fine it gives full auto focus. I have used it with my canon EF 24-105mm 1:4 L IS USM opened the image in lightroom 5, and the 24-105 becomes 147mm and my canon EF 70-200mm 1:4 L IS USM becomes 280mm according to lightroom 5.I have full auto focus at F/11 on both lenses. True I have not had time to fully test and use this converter and only taken a few test shots so far but I am very happy with the results. And I cant see any loss of image quality in my test shots.I did try it on my canon 550D and found that I had auto focus, I use my 7D for all my photography work I would recommend this to anyone with a canon 7D and 550D.

I'm impressed. Had some doubts before buying this kenko and tried to read everything alover Internet to make sure I was taking the right decision. Do I lose IQ? Yes, marginally. But it depends of the lens. I bought this kenko mainly to use with two lens: Canon 70-300L, simply amazing! Worth every penny! Beyond my best expectations. Canon 85 mm f/1.8, very good but not so amazing as the L lens. I can take good shots at f/2.5 but the sweet spot starts at 2.8. I seriously recommend this kenko 1.4 to everyone especially this série (DGX PLUS) that I've read to be the more well build. If it is true, I don't know but evaluating the results, I am satisfied and I am quite ixel peeper.

This is a great converter. It fits any EFS lens (not APSC none of them do) and focusses perfectly despite what some would have you believe..For example I have a Canon 70 and use the converter with my Canon 70-200l f4 and it focusses instantly at all f stops up to f22. Very useful as the lens alone on a crop sensor gives 112-320 and with the converter on its just under 160-450 It also works perfectly on, for example my Canon 35mm f2.0is where it becomes an effective just under 78mm f2.8 is lens (very useful length for head portraits0. So overall very versatile and I doubt most people would notice any loss of image quality at all in normal use.

I bought the 1.4 tele converter, primarily to use with a 105mm macro lens. Results are excellent and the converter, in real word photography and to my eye, has virtually no degrading effect on the image at all. It locates very securely to the camera, as it does to the lens - on a Nikon mount. Out of curiosity, I have tried it on other lenses and found that in general, up to about 200mm the results pretty well equate with the macro.Though in practice I don't use the converter very much. I would most certainly buy it again as it represents excellent value for money, takes up next to no room and on occasion is invaluable.

I had been promising myself an extender for quite a while but had always been put off by the prices Canon charged . Having read the reviews and along with the price I decided to invest in one of these Kenko one,s . It arrived very quickly and was well packaged .It was mainly for use with a Canon EOS M3 Camera with which it gives greater range with no noticeable drop off of picture quality but I also used in on the full frame Canon 6D with similar results but because it is full frame there is a drop of in range , although not by a lot .I would recommend the Kenko 1.4 to any any one .

These kenko converters are really making themselves a name , both in quality build and performance.Id previously used a Nixon tc 200 but as this was only manual, and I couldn't possibly afford the latest Nixon tc in order to get full auto and ttl mode, I decided to go for the kenko tc.I use it on my nikon 300 prime f4, 105mm f2.8 macro and a sigma 150-500mm.The kenko tc works very well on all 3 lenses, giving me a whole new range of lenses.The kenko 1.4x tc gives excellent value for money and is seriously worth considering if you are in the market for a tc .

I use a D7500 usually but tried this on the D60, D3200 and he D7500. Fitted all but would not lock in place on the D60 and felt very tight going onto the D7500. Engagement on with lenses was positive though with 18-55 and 70-300 Nikons. Light loss on the 18-55 made it pointless but on the 70-300 it was not excessive. Auto focus took longer and sometimes hunted for a second but it did achieve 3D tracking happily and the image quality was barely impacted. It didn't give as much magnification as I had hoped and I would have gone for 2x having used it now.
