Kenko Teleplus MC4 - Converter DGX - Sony E-mount
Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length of any lens with which it is used. The Kenko TelePlus MC4 AF 1.4x DGX converter has the effect of multiplying the focal length of your lens by 1.4x. The MC4 AF 1.4x DGX converter has genuine Gate Array IC (Integrated Circuitry). It means the converter's unique circuitry maintains signal integrity between the camera body and lens.The 4-element design is made with high quality multi-coated optical glass supplied by Hoya Corporation, the world's largest manufacturer of optical glass. Full AF operation with the TelePlus MC4 AF 1.4x is possible using camera lenses with open apertures of F4 or brighter. AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors properly. (Manual focusing may be necessary when using lenses with smaller open f-stop values than that given above.) The DGX TelePlus converters have updated circuitry to record exif data more accurately. In the exif exposure data (meta-data recorded with a digital picture) DGX converters record the equivalent aperture and focal length of the lens setting plus teleconverter. Optically and mechanically they are identical to the prior high-quality DG series converters.

I use this in conjunction with my 70-300mm Nikon telephoto zoom lens and has certainly improved my long range shooting capabilities. I think its good for anyone on a low budget that needs a little extra reach. Still experimenting with low light/auto focus operation but so far seems to be working as advertised. B&H was very easy to deal with, been using them on & off for about 30+ years, still not disappointed.

This Teleconverter worked really well for me. No noticeable image degradation and gave me the extra reach I was looking for. Build quality is really good. The attachment points are metal on both the front and the back, the lens release works easily, the lens is stable with no noticeable wobble, and there are alignment dots for both the camera and the lens attachment points. There are a couple small issues that make it clear this is not a top-of-the-line teleconverter. First is a hunting issue with focus in certain situations. It's not always a problem, but some tough subjects make it more evident. Also in my situation the adapter does not pass along updated EXIF focal length information. My camera reports as if the lens is directly attached, giving erroneous zoom ... MoreThis Teleconverter worked really well for me.

I also had an issue with the camera not recognizing the lens sometimes. It would suddenly stop allowing me to change the F-stop and focus and acted as if I had no lens attached. Reattaching it to the camera body (while still attached to the lens) seemed to fix the issue each time. I had this happen a couple times to me, luckily not at a critical moment. Small issues aside, this is a great teleconverter at a budget price (at least considering the price of some alternatives). I would recommend. Sony A77 Sony SAL55300

Used it with my Nikon D500 and 200-500mm f5.6E ED VR lens. I really like how the image appeared on my photo for stills though. AF hunting sometimes, especially in lower lighting but that didn't bother me at all. Not that good in BIF, but it does the job. It's the best bet you can give for your buck. Definitely recommended.

Sometimes a bargain isn't a bargain. Bought it for my Nikon G and E-type zoom lenses.Autofocus is always off with this teleconverter. Garbage. Avoid.I will never touch this brand again. Perhaps the native brand is the lowest risk. That will be my future approach.
All metal mounts and fits well. I have a Tokina 300mm 2.8 prime, and was looking to get maximum reach, so I purchased the Kenko 2X. Was a bit disappointed, just could not get a sharp picture with it. So I went to this 1.4X. Difference is like night and day. Very sharp pictures. I tried it on my already sharp Tam 90mm macro...wonderful! I cannot see any degradation in sharpness. There is a bit of contrast lost, but no biggie. Anything worth keeping is worth tweaking. The 2X also performs well on the Tam 90mm. In this digital world, one has to experiment to find what fits with what best. So far, this 1.4X is a bargain. For my wildlife pics, I can more than live with a 630mm lens setup that comes out very sharp indeed. Well done Kenko.
I asked B&H if this was compatible with my Nikon D3200 using the 55mm-300mm zoom lens. They said the auto-focus might not work in all lighting conditions. I was okay with that. I used this at my grandson's high school graduation that was held in the football field. It was early evening with sunny skies. It focused perfectly. I got great photo's from the bleachers 40 yards away. I even got a great video clip of him walking up and accepting his diploma. Picture quality was very good. I am not sure if the auto-focus will function in reduced light, but I am very satisfied and manual focus is not an issue. This is a very inexpensive way to boost a 300mm lens to 420mm. I compared using the converter to taking a photo without the converter and enlarging it to the same ... MoreI asked B&H if this was compatible with my Nikon D3200 using the 55mm-300mm zoom lens.

The tele-converter photo is much clearer.
I hate teleconverters. So, why have I bought 4 of them in the past month? Because a FF (full frame) teleconverter of 1.5X magnification basically converts an APS-C lens to cover FF. This converter is really a little less than 1.4X, but it produces very good image quality and most APS-C lenses cover a little more than the APS-C frame, so it is pretty effective in converting APS-C lenses to cover FF. The other converters I tried included one of the older 1.5X Kenko converters -- but that was optically much poorer and, oddly, was actually the exact same magnification as this 1.4X. In fact, of the four converters, this was easily the highest IQ with an old Rokunar 1.4X coming in second. The other issue with teleconverters is how they report the properties of the lens in ...

The other issue with teleconverters is how they report the properties of the lens in front of them. They should adjust the focal length and aperture reported. This A-mount converter has 8 pins and correctly reports the adjusted lens properties -- and works on an LA-EA4! Sony says teleconverters will not work on the LA-EA A-to-E mount adapters, so this was a pleasant surprise. Another converter I have that also reports correctly indeed does not work with the LA-EA4 to the level that the camera body sees no lens attached; yet another teleconverter which reports incorrectly works, but with the wrong focal length the sensor-shift anti-shake is not as effective as it could be. Autodfocus is less reliable with any teleconverter, but this one works fairly well. In sum, this teleconverter is well worth the price if you want to use an APS-C lens on FF... which is probably not why anybody else has bought it. ;-)
First, let me say that B&H shipped on time and this order was received on time.That being said, the Kenko Teleplus HD DGX 1.4x is the worst piece of garbage I have ever purchased. I'm hoping their buyers read this review and save other customers from my grief.I'm currently out of the country and it's too late to return this trash.I once received the gift of a Nikkor 43-86mm zoom lens for my Nikon F2, which used to be in first place for garbage optics. When I tell people I have one of those, the only response is laughter.Well, this Kenko teleconverter is far worse. At least that old lens came close to focusing correctly. The Kenko guarantees you're way off.Regarding the requirement that you have Nikkor G or E lenses, those are all I have, not that it ...

I don't know why the camera even thinks the image is in focus, it's so far off.My recommendation: Buy a reputable brand, any reputable brand. In my opinion, this isn't it.Trust me: My opinion is in super-sharp focus. I wasted $180+ (including sales tax).My only criticism of B&H is that they carry such garbage.
I have finally had the chance to use this teleconverter. The reviews I saw were pretty good. Only now, I'm wondering if they were written by the manufacturer's employees or family members.Everything I shoot is out of focus. That, in itself, is pretty amazing.It is the worst piece of optics I have ever bought. I hope I can get a refund and get the Nikon teleconverter I should have gotten in the first place.Total garbage! Don't even consider buying it!
I have rented big telephoto lenses before when I wanted to photograph wildlife in the distance. I always found them to be more trouble than they were worth. I admit that I am not the type of wildlife photographer who hides out in a blind or is happy to stand around in a crowd of photographer with our units mounted on display chatting and bragging while waiting for that wolf cub to wake up or that bird to peak out of it's nest again. For me, it is usually the case that just when I get that awkward lens and tripod set up, some event will happen that is too close to use this blasted contraption.Besides, I am cheap. I am not willing to choose between a lens or a corvette. So, a teleconverter for my Sony zoom would seem to be the tool of choice for our upcoming road trip ...

Did somebody say trade off. ? Several years ago i thought the answer was going to be a 2X teleconverter. But I learned in the field that the loss of sharpness and the loss of stops turned my perfect shots into perfect nots.Several years have passed since that lesson. Technology has improved and my own knowledge has almost kept pace. Well, I learned to be less greedy. Instead of a 2X, this time I decided to try the 1.4X and I studied up on the various brands available. At first I thought that this Kenko teleconverter was too cheap to produce quality. But, with B&H's generous return policy, I decided to give the TelePlus MC4 AF 1.4X teleconverter a try. As usual, I received my order rickety split from B&H. I have been on my patio almost daily practicing on the our assortment of hummingbirds and other springtime migrants and I have been pleasantly surprised at the sharpness and the range of f-stops available to me. This is just the kind of lightweight, unobtrusive camera component that makes my photographic passions seem like a hobby rather than burden when I travel.
