Sony Alpha FE 100-400mm F4.5-5.6 GM Super Telephoto Zoom Lens

Lightning fast and very sharp; I only have one minor moan: the focus limiters are very easy to engage, using back button focus they are totally unnecessary and are best disabled otherwise a stunning lens.

Needed a longer zoom lens, and after doing a lot of checking with other makes, weight, size, price and other reviews, decided on this 100-400mm. Glad i did, very fast focusing, lovely smooth zooming in and out and not too heavy, even with a vertical grip, was able to do hand held shoots. Picture quality was excellent.

This lens is fantastic and so versitile and probably the most versitle lens you can buy, its very sharp and paired with the a9ii and the a1 it gives exceptional results, the best thing it has a minum focus rage of 1mtr so for semi macro especially butterflies which are notoriously difficult to get close to this lens is a game changer as well as the reach for wildlife with 400mm

Absolutely in love! Amazing lens, such a good quality can catch every detail

Excellent build quality. High quality construction. Not as heavy as I thought it would be, which is good. Has three assignable buttons one can use in portrait/landscape orientations. Detachable foot. Slide door on hood enabling access when wanting to adjust circular polarizing filter--all very practical. The focus ring is buttery smooth, as is the focal length adjustment ring--very good for video use. The optical image stabilization works seamlessly on my A7RIII. At 400mm, I have been able to take sharp images hand held at 1/80th of a second shutter speed. The lens is very very sharp at all focal lengths, which is why I said "Why Buy the 70-200 GM When You Can Have the 100-400GM?" If you need a telephoto zoom for portraits in low light, this is not your lens. But I feel very comfortable saying this lens would make an excellent portrait lens in studio and outdoors in good lighting. Don't forget 400mm at 5.6 isolates the subject and blows out the background just as well as 135mm or 200mm at f/2.8. No need to worry so much a HSS to get that effect, either.

I have used this lens with my A7RV and it is more than capable of resolving the 61mp sensor despite being an older lens, rendering a vast amount of detail. Brilliantly sharp and very quick to autofocus in conjunction with the camera system. Recommended without hesitation.

I hired this lens for two holidays before taking the plunge and buying one for myself. I've been thrilled with the sharp images I've obtained of wildlife. 400mm is enough to capture animals at some distance without being so heavy that I can't hold it steady. 100mm is short enough for the animals that come somewhat closer. It's an excellent lens which works well with my A7iii camera.

I rented a copy of this lens to assess the dífference as it is quite expensive. It was apparent after the first day this was the balance of performance, focal length and weight was excellent. I traded two thirds party lenses, both very good, when I bought this lens.

takes too long to focus often, very disappointed, i have all g masters and thought they would be faster and keep focused.

So happy with my new camera and lenses. Great quality pics with ease of use. Far exceeded my expectations

so far so good. clear, focuses well and not so heavy to cause sore arms neck etc

Excellent lens, sharp and quick AF. Much smaller and lighter for travel than my 200-600. Works great with both the 1.4 and 2.0 TC when there is enough light for the F-stop reduction. Has short minimum focal distance and have used for everything from wildlife to sports, landscape, flower closeup and portrait. Primarily use for travel when I don't carry 2 bodies fitted with other lens. Big disappointment is no zoom lock on external zoom GM lens. Has softer/tighter ring but lens creeps even on tighter setting. I knew this when I bought it but other features offset.

Have had for about 5 years. It is truly great. No regrets about spending all the money.

I bought this lenses as the 2-600mm became too heavy for my injured shoulder. Although I have been totally satisfied using my 70-200mm with the 2X TC, the added reach combined with great autofocus, sharpness and lighter weight make this lens my "go to" for birds.

A compact and fairly light lens which I have used for sports photography eg. football and the optical quality is superb

Having owned the excellent A-mount 70-400 f4-5.6, which traveled with me for mainly wildlife photography all over the world, I wanted the performance benefits of this lens with the Alpha 7 etc series of FE mount bodies, in particular the ability to use the telephoto converters with a rich range of features. I am delighted to have made the transition. Results with and without the TCs are excellent and the autofocus features are a real pleasure. Highly recommended.

Had this 3 weeks and it is a superb example of a 100-400 professional zoom.

Ive been wanting this lens for a couple years but i kept not buying it because its so expensive. And being retired money is not easy to come by. Im 75 years old now so it was really a want instead of a need. So i just want to let others know that this lens is awesome and a definite keeper. Wish i could have bought it sooner. I have a Sony telephoto 70 to 200 f4. But found it just didn't have the reach i wanted a lot of the time. I read the reviews of others trying different brands and they didn't seem satisfied so thats why i got the Sony….its focus is amazing and I'm totally satisfied.

I bought one of these about 3-4 years ago when I first changed over to Sony as, other than the 400 f2.8, it was the biggest lens that Sony did. Soon after though, they brought out the 200-600 so I bought one of those as well. Last year I bout the 400 f2.8 and decided to sell my 100-400 to a friend. Big mistake as the 100-400 is so good and so useful so.... I bought aniother copy a few weeks back

I have owned this lens for 3mth. It’s a great lens for wildlife and other types of photography. I use it predominantly handheld and have some great results. It’s a pity the zoom isn’t internal like the 200 -600, in hides when zooming in and out particularly behind glass mean moving back and forwards. The lens is light weight enough to use for a long session handheld and travel. I do on occasions use the 1.4x extender and again have had some great results. If you’re looking for a versatile lens that give great results, then this is a good choice.
