Used in combination with a Sony Alpha a9 and a Sony FE 100-400mm f/4.5-5.6 GM OSS lens, this teleconverter works so well that you don't notice it's there.I come from Canon, where I regularly shoot their latest 1.4x and 2.0x teleconverters with their latest Series II super-telephotos. On a Canon 5D MkIV body, there's a noticeable slow down of initial focus acquisition and decline in tracking ability. With this Sony, the initial acquisition stays instantaneous and tracking is from another world, it's so good.I've read that this teleconverter was designed for Sony's G Master lenses, so don't expect it to work with other lens/body combinations.Also, I read a review where the user was complaining about slow response when he put the FE 2.0 teleconverter on an ... MoreUsed in combination with a Sony Alpha a9 and a Sony FE 100-400mm f/4.5-5.6 GM OSS lens, this teleconverter works so well that you don't notice it's there.I come from Canon, where I regularly shoot their latest 1.4x and 2.0x teleconverters with their latest Series II super-telephotos.

Apparently, he didn't realize that the a9's AF system are not designed to work above f/8. I haven't tried it, but I'd bet that Sony's FE 2.0x teleconverter would work great on the G Master 70-200mm f/2.8 OSS. (Something to look forward to, as I slowly replace my Canon equipment).I shoot birds and wildlife and I've taken no test shots with this teleconverter. I'm almost certain that you'll see slight deterioration in image quality at magnifications, such as 200%. For real world results, having 560mm at my beck and call, in a small, light package is wonderful.

It's a teleconverter. 1.414x the focal length, 1.414x the f-number, 0.707x the depth of field, a bit over 2x the hyperfocal distance (depends on which definition you pick), lens abberations magnified by 1.414x, etc.I've used it with a Sony SEL200600G (200-600mm f/5.6-6.3 G OSS) lens on an ILCE7RM4 (7rIV) camera. With that lens, the TC is better than the lens and so doesn't reduce sharpness. It *does* magnify lens aberrations, so the (slight) longitudinal chromatic aberration of the lens becomes more noticeable. Note the fringing on the Turkey Vulture image, even after it's been processed by DxO. This is expected, of course. It's not the TC adding aberrations, it's just magnifying what's already there. This is part of the reason the big prime lenses cost so much: ... MoreIt's a teleconverter. 1.414x the focal length, 1.414x the f-number, 0.707x the depth of field, a bit over 2x the hyperfocal distance (depends on which definition you pick), lens abberations magnified by 1.414x, etc.I've used it with a Sony SEL200600G (200-600mm f/5.6-6.3 G OSS) lens on an ILCE7RM4 (7rIV) camera.

This is part of the reason the big prime lenses cost so much: they have fewer aberrations to begin with, and so can use these high-quality TCs and get even better image quality.

I must admit I had my reservations after reading some of the reviews, but I’ve been more than pleased with the results. Yes, you do need more light because of the f-stop loss and the autofocus does take slightly more time but with good light, the shots are impressive. Pretty darn sharp and the extra reach is exactly what I needed for my bird photography. Definitely worth the buy though I wish it were a little less expensive. All things considered, I’d recommend it if you want extra reach!

I bought this Sony 1.4x Teleconverter to use with my Sony A7R5 and Sony 200-600mm lens. Before purchase, I got tack sharp 61 mpx images at a 600mm reach. Now I get tack sharp images at an 840mm reach. It doesn't produce quite as well in APS-C crop mode. Image quality is hit and miss. I have also used it with my Sony a6600 APS-C camera which gives a 1260mm reach. Image quality is spotty. Some images are razor sharp and some are soft. The loss of one stop of light doesn't seem to make much difference with my kind of shooting. Photographing birds and wildlife at F9 on cloudy bright to sunny days gives good results with ISO's below 1000. I sometimes shoot at F11 and I still get good images. For my camera and lens, I give it 5 stars.
I wanted more reach for sun & moon shots with the 200-600. So I bought this teleconverter soon after the lens. Had them less than a month. So far, very happy.With an APS-C sensor, at 600mm this teleconverter results in 1,260mm, which fills a decent portion of the frame. Relative size is shown in the two uncropped photos. The sun was taken with a Thousand Oaks white light solar filter, showing a few sunspots and some surface detail. The moon was shot on a hazy night.Detail on both are quite good & meet my requirements. I also have more powerful telescopes, tracking mount, and cooled astro cameras for these kind of shots. But I often want a quick photo or timelapse of a moonrise or sunset, without an hour setup. This allows quick, low-hassle- high magnification ... MoreI wanted more reach for sun & moon shots with the 200-600. So I bought this teleconverter soon after the lens. Had them less than a month.

This allows quick, low-hassle- high magnification shooting with great results. 200mm - 1,260mm is quite a range for one lens (full frame vs. APS-C with 1.4tc), particularly with such good image quality.I've included an uncropped moon photo at 600mm with a full-frame sensor, for comparison. Nice for landscape, but rather small for isolated solar or lunar shots.I notice very little, if any, image degradation with the a6600 (APS-C) and a7iii (24MP full frame) sensors when using this teleconverter.
Lensrentals gear is always in great condition. I rented 2 Sony lenses (200-600 mm and 100-400. Also a Sony 1.4 Teleconverter. All were in like new condition. I used them on Sony’s FX6 cameras. Both were amazingly sharp. Auto focus was fast and accurate.I have been using Lensrentals for over 10 years. Staff is friendly and knowledgeable.They are my “goto palace” for all my photo equipment needs.
This teleconverter came with a bit of disappointment for me. I'm a sports photographer and after shooting with every main lens in Nikon and Sony I got to say this specific teleconverter is mediocre in low light conditions at best. I didn't expect to pull miracles but expected for something at this price point to be a solid and reliable piece of equipment to go with my 70-200 F2.8GM lens. It works perfectly in the middle of the day, but as soon as the light starts falling it causes the images to lose considerable sharpness. Enough for me to hesitate if I should keep using under low light conditions. I will be keeping it because its a good alternative to spending $+ on a new lens and it gets the job done but after shooting with the 400mm 2.8 or the 100-400mm F4 and ... MoreThis teleconverter came with a bit of disappointment for me.

I had tried the 2x and that one doesn't even cut int in daylight so decided to give this one a try. Also you will find that it misses focus 1 out of 10 times. If you got the money, or the time to wait, I would suggest to either buy the 100-400GM or 200-600G than spend $ on a tool that only works in daylight settings.
I got this extender about 3 months ago. Its an ok solution for wildlife I guess but it has some major drawbacks. The loss of 1-1.5 stops of light, (at full extension on the Sony 100-400 you get f8) causes some slower AF and loss of dynamic range. On bigger slower subjects you will not notice it that much, but on smaller birds it might trouble you if you are using a high end camera like the r73(which I am). Also there is a reduction of sharpness. Again more obvious on smaller subjects. If you are going to use this extender with 70-200 2.8 lens maybe its a different story. You can watch photos taken with this extender on my Flickr account sfiron. Look for Giraffes and Bee-Eaters. The first ok the second shows for the soft sharpness. Also the R73 with the 100-400 lens ... MoreI got this extender about 3 months ago. Its an ok solution for wildlife I guess but it has some major drawbacks.

Also the R73 with the 100-400 lens and extender is too slow to focus on moving birds. Might also be a product of the amount of light taken in by the lens+extender combination. Im thinking the chip-set or focus drive on the camera or lens, is not strong/fast enough as well...
I've had mixed luck with teleconverters in the past. Some were decent and some not good at all. I am using this with a Sony FE 200-600mm lens and the results are outstanding, very sharp. In addition to using it while out and about I did some tests in the house at nearly 600mm (I moved the zoom ring a little by accident before starting the tests) with and without the converter. I shot a test chart at about 25 feet from the camera. When the test shots were viewed at the same image size (the chart was the same size on the screen) the images with the converter were just a bit sharper and of course were of higher resolution. Essentially the increased magnification more than made up for any very slight degradation of IQ. I did the test shots with the converter both wide ... MoreI've had mixed luck with teleconverters in the past. Some were decent and some not good at all.

Essentially the increased magnification more than made up for any very slight degradation of IQ. I did the test shots with the converter both wide open and stopped down one stop. I used the same f/stops for the shots without the converter. If anything this gave a slight advantage to the non-converter shots. In any case there was little difference between the shots at the two f-stops. Well worth the cost when you get can't get close enough to your subject. Highly recommended. I should also mention that the FE 200-600mm is excellent in its own right. Very sharp even wide open and easy to handle. It does not extend while zooming which is nice.
If you do your research on these you will find that many people who review them are not fans. I’m here to tell you they are right! I’ve done my own side by side comparisons and yes the sharpness is compromised. If this doesn’t bother you then get it. If your like me and like sharp photos, I’m not a fan of cropping by I rather crop and it will still look sharper. I’ll be looking to sell this. 1st picture with teleconverter and second picture without. I don’t know if they down size the file here tho. Good luck on your choice!
