Customer Ratings & Reviews

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 use this Sony - 1.4x Teleconverter with my Sony 70-200mm f/2.8 GM Ver 1 on a Sony A9 and works really well. I believe it stops down to f/4 but still seems to be fast-focusing and sharp with decent light of course. Nice addition to my gear to get that extra reach option when my 150-600mm zoom lens is not at optimal range.

Easy to put on. Can’t wait to take another trip to Europe.

This is a good money saver if you want to increase focal length and have one stop of light to spare. I have this in my bag every time I want to carry less weight in my camera bag and have my longest lens increased 1,4x focal length.

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!

I’m really enjoying the extra reach add on to sony 100-400mm. and I haven’t noticed a decrease in image quality with autofocus. It is a good companion with Sony 100-400mm FE lens. it works well with A6000 and A6500

I purchased the Sony 1.4 teleconverter to use with the Sony FE 100-400GM zoom lens. The converter does a great job of extending reach with no noticeable image degradation, although as with all converters, it does cost you on the maximum aperture available on the lens (easily countered with higher ISO settings). My primary use for this is for wildlife but I will also use it at upcoming air shows. Since Sony's longest native FE lens is the 100-400, the 1.4X and 2.0X are necessary to extend reach.

There are two teleconverters that work with the F2.8 70-200mm GM telephoto lens. With the 1.4 X you lose only one F stop so I bought that rather than the longer 2.0. The clarity and detail of this lens and extender combination is amazing. I haven't tried to capture birds in flight yet. All of the pictures I have taken have been with the camera hand held. As far as I can tell, there is no reason to use a tripod.

Standard teleconverter with a loss of one stop of light for 1.4x reach with no loss of image quality.

This Teleconverter really works. The pictures stay clear, the focusing is fast. It is small and does not take up a lot of space. I would highly recommend it for getting that extra reach. Just check the sony lens you have to make sure it is compatible.

I have both the 2x and this 1.4x and while I like the extended reach of the 2x, the 1.4x maintains all the focus features and is sharper with my 100mm-400mm Sony lens. I highly recommend this add on.

I purchased this teleconverter to increase the focal length of my Sony 100-400 GM lens paired with my a6500 body. I’m so impressed with the image quality! The only compromise is losing one stop of light (maximum aperture of f/8 at 400mm).

I was told this with the Sony 200-600 on an A9 was an amazing combination, and after trying it I must agree. Just know that it can only be used with a small list of lenses since it sticks into the back of the lens about an inch (most lenses are flat where the mount to the camera with no recess)

Very nice addition to Sony lens (70-200mm in my case) - no problem with quality of photos, but gives you that extra reach which sometimes very good - at the price of 1 f-stop... and some amount of money :-) Worth it from my point of view

The amplification is good gives you a closer look as expected, you loose light but it worth the trade.

size smaler than canon 1.4x teleconverter, and image result sharp

I really like the quality and added reach of this teleconverter!

I purchased this teleconverter base on many reviews that I have read. In reality as a Wildlife photographer I am always looking for getting closer to the subject minimizing the surroundings and environment of the wildlife. I am currently using it with a 200-600 mm Sony lens and it doesn’t disappoint. The downside is that is more for a daylight use due to the fact that you will lose light it turns into an F8 F9 aperture. The focus is still very accurate.

1.4 better than the higher converter betted f stop and shutter speed also image I think is better great addition to your lense collection lot og bang for the buck and extends your reach when you need to get closer to the action

Perfect to boost my 200-600 range for wildlife photography
