This 2 X Teleconverter really helped bring subjects closer with minimal if any noticeable loss in sharpness.

I bought 'Mighty Mouse' to add onto my Sony FE 200-600mm lens to take closer shots of ky astrophotography. Take a llok at the moon shot!

Fantastic on mmy gmaster ii 70-200 sony kens. I dont see any quality changes i did a amazing photography moon with it and wild life. Supurp .

As expected, the teleconverter fits tightly onto any Sony emount body, with no play in my specific unit tested on the Sony a7iii, a7iv, and a7v with the 70-200 gm ii and 200-600 g lenses. If you have ample light, this product works exceptionally well, but if you're in poor lighting the autofocus will struggle.

First off, the title shows this is a 2x teleconverter, while the description states this is a 1.4x teleconverter. This is a 2x converter. Secondly, I'm using the teleconverter with the Sony G Master FE 100-400mm which results in 200-800mm focal length. Camera Body: Sony A7ii So how much light is lost? My camera shows F9 at 200mm and F11 at 800mm. I first tried shooting subjects that were very far away to test the limits of the teleconverter. It's quite a challenge to keep the camera steady and get focused, but it's not impossible. Don't try to photograph tiny birds like swallows that are 30 feet or more away. You'd be asking for too much. It's much better to find a subject that is well within reach of your actual focal length or just out of reach. That's where the teleconverter really shines. There's no huge penalty for shooting wide open at 800mm if your subject is in the right range. You will get amazing closeups and if you're into macros you will get excellent detail without having to get very close to the subject. If you're photographing wildlife, this is great since you'll be able to get closer shots without getting physically closer and potentially disturbing your subject. I didn't notice any major loss of quality in images. Some images came out soft but this is more of a focus issue. You will find it difficult to lock in focus at times. Overall my images were beyond acceptable. When loading up photographs for editing I don't need to do a major amount of post processing in order to make the shots look good. I'm editing just as I would edit any photo without a converter. You won't be spending a lot of time cleaning up quality loss. It's a little pricey, but I'm definitely satisfied. If you have the right expectations you will enjoy using it.

If you own ANY of the white Sony FE telephoto lenses (like f2.8 70-200mm or the f5.6-6.3 200-600mm) this is a no brainer. 2 stop loss, auto-focus works great. There seems to be a lot of amateur photog's who buy this thinking it works with ALL Sony lenses. Please do your homework. There's a short list of telephoto lenses this is designed for. Inexpensive and compact. Doubles your tele-range. RECOMMEND

Works Great!!! It’s awesome for night sky photos. Comes in clutch when needing to zoom in more

I had a little bit of trouble in the beginning trying to use it but once I figured it out it worked really well!

I bought this converter for my Sony Gmaster 70-200 f2.8. I was considering buying the Sony Gmaster 100-400 f4-5.6 but ultimately decided on the 70-200 and then bought the 2x converter. hopefully you realize that the 2x converter causes you to lose 2 stops of light so it turns my f2.8 into a f5.6 when i have it on my lens. if you are outside in sunlight it's not a problem, but indoors with good lighting it hurts but is manageable. in the end it roughly equivocates me owning the 100-400 but at only 20% the cost. this is a good option if you don't want to spend the money on both lenses or if you want to turn your 100-400 into a 200-800 but you probably can only use that in bright sunlight. BE AWARE: this only fits these two lenses that i have referred to here! no other lenses work with it!

its a great addition to your setup, and it works great with my 70-200 GM 2.8, highly recommended and specially for slow moving subjects or steady subjects, sharpness is on top notch still.

Great lens, but not one I can use since it was delivered but without the Sony - FE 70-200mm F2.8 GM OSS II Full-Frame Telephoto Zoom G Master E mount Lens that I also ordered. It's difficult to use the teleconverter lens without the zoom lens. I bought the teleconverter so I could boost the zoom lens. If I return the teleconverter lens, I will be charged a restocking fee.

It’s well made and it give you the extra zoom. Works great if you using for sports.

Originally bought the 200-600m lense but it was enormous. Way too big to carry around everyday. Swapped it for 70-200 and bought the teleconverter. Its freakin awesome. I take a lot of sports pics, my kids baseball, nephews football.

While it would be great if this would work with all Sony E-Mount lenses, I knew before I bought it that it wouldn't. That said, it gives me a doubled zoom of my 70-200mm 2.8 G2 without too bad of an impact on the aperture. Cheaper to go with this option than to buy a 400mm lens to add to my bag.

I was a die hard Nikon user and fan. I switched to Sony and no looking back. I couldn’t get a sharp shot with a Nikon 2x teleconverter on my 500mm Nikkor lens but this Sony TC works wonderful. I can even get it to autofocus for Birds in Flight with my 600mm lens for an equivalent 1200 FOV. Unbelievable how good it is when paired with the A9. Sharp even at f/8.

Bought this as an alternative to buying the more expensive f2.8 600m lens for my Sony alpha a7 IV. It has done an excellent job when taking long-range soccer photos. It does need to be stabilized on a tripod or bipod to prevent motion blur, but an excellent purchase when compared to the more expensive lens.

[Employee of bestbuy] I didnt have to invest in a 400mm lens, i can use my 70-200 as effectively as a 140-400 f/4

Love that I can extend my range on my 70-200mm GM II, 100-400mm GM, and 200-600mm G lenses. The loss of light barely affects my surf photography.

Fantastic build quality just like the G Master lenses I like that it is so compact that with it on my 70-200 G Master 2.8 it still fits in all my bags with out modifications to the bags

This teleconverter worked well for converting my 200mm to 400mm for sports photography. You do sacrifice aperture to do this, but it does the job on a well-lit sports field.
