Product Reviews

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.

I've been unable to get a refund after purchasing product here in the online sony store. Horrible Pincushioning from 330MM to 400MM makes lens unusable for purchased purpose. Sony hasn't returned my messages or emails. Please issue a refund or exchange to a working lens. Received from Sony on March 19, 2024.

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.

After using this lens for almost a month, I am extremely pleased with it. Coming from the 200-600G, listed below are some of the advantages that I appreciated. IMHO. Lighter and smaller to travel with. Close focusing distance. More appropriate for diff genres of photography. More sticky AF for birds in flight. Combines well with 1.4tc Fits most shoulder bags Sharper images. I thought I would end up with just one of the two in comparison. However, I had decided to keep both. They are both excellent lens for different purposes.

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.

I bought the lens seconhand from LCE recently as a treat for myself after coming into some money, as I have always dreamt of owning it. It is paired with my Sony A9 and what an amazing combination it has turned out to be. It is a bit of a learning curve how to use it, with the incredible focal range, but I am getting used to it now. It's great for landscapes, wildlife, portraits of the family and of course sports (but not yet had chance to try this yet). The image quality is out of this world even when zoomed fully in, the build quality is of course excellent for a GM lens and it has now opened up a whole new world of photography for me!

I've had this lens for a few months now,very happy with it,excellent quality.

Image quality is superb, reminds me of my old Sony A mount 70-400G but seems lighter and easier to handle. I find the zoom ring a bit stiff even on the smooth setting compared to similar zooms from Canon and Nikon. All in all an excellent lens.

Not a lightweight lens but very high quality and sharp across the range

Spent the last few years using various other telephotos such as the sigma 100-400 and the Tamron 70-300, mainly because they’re cheaper. Finally decided to take the plunge and spend a little more (double). All I can say is I should’ve gone straight for the Sony! Better in every way and just pure joy to use. Puts a smile on my face every time I pick it up!

Got this for wildlife photos and it does not disappoint. Very happy with the image quality and how responsive the lens is.

only take it off to switch to a wide angle lens. produces sharp images and so far tracks moving objects with incredible accuracy. paired it with the 1.4 teleconverter and it is still super sharp and fast. in my opion it is well worth the price I paid

Recently purchased this lens and the build quality and performance are up there with the best.

I bought this one month ago and have been using it on my a9 have not managed to take an out of focus shot absolutely superb lens

I have owned and used the Sony 24mm, 24-105 and 70-200 lenses. I also have the 24-70 2.8. Despite other lenses being more compact, the Sony 100-400 GM is on my a7Riii all the time. I only switch when I want to photography something specific. Many people say the 70-200 is a good all around lens, but I now use the 100-400 instead, which has replaced the 70-200. I love the close focusing distance, fast focus and image quality from the 100-400GM. And yes, I use it mostly hand held, which is a testament to the overall handling of this lens.

Incredibly sharp, very fast focus, good minimal focus distance. The G Master delivers everything it promises, but you do have to pay for it.

I use other 100-400 for other manufacturers but this one sit on top in so many things, the results that you get are amazing, paired with a high resolution camera like A7R show no laws what so ever

This lens is wonderfully well-designed and built and relatively small and light. It produces outstanding images from an A7R4 at 100mm from wide open. At 400mm it can produce very sharp images in evenly lit scenes. My copy suffers from veiling if there are highlights in the scene, with loss of contrast. I'm assuming that the coatings are not fully up to the GM label and price.

I have recently moved from A mount to E mount and required a telephoto zoom lens, as I like landscape, sports and moving objects like birds. So I chose this lens as it it had everthng that I required. It is just a fantastic lens with great zoom capability

I knew this lens was good and since its purchase it has exceeded all my expectations, a wonderfully sharp cary around all day lens

What a super lens, it's done everything I’ve asked of it. If it wasn’t that I need more reach sometimes I would leave it on the camera all the time

Acquired for my new ILCE-74M. My first ever Sony product.

First impressions, using it with my Sony A7R111, razor sharp images at all focal lengths, focusing fast and accurate. The lens feels well balanced and relatively light considering it’s size. Seems easy to use handheld but I use it mostly on a monopod, my only criticism would be the tripod foot doesn’t have a Swiss Arca fitting requiring the purchase of a suitable plate. Quality of the lens appears great but I can’t comment on durability having only had it a short while, overall I think this is a great lens and anyone taking the time to use it properly certainly wouldn’t regret the purchase

This lens gives bitingly sharp with images and produces good Bokeh. I don't find the focussing as good as I had hoped from reading reviews beforehand

Great telephoto lens. Not good for low light applications tho. Day light photography unless you want to use crazy high iso. Auto focus is definitely on point!

This is a quality lens giving pin sharp images throughout the zoom range. It is also excellent to use as a macro lens, and also works well with the 1.4 converter. It isn't the lightest lens but I have no problem carrying it all day on a black rapid strap.

well designed lens. The selection of available lenses is wonderful that was the reason i purchased the Mirrorless camera.from Sony and dd not buy the Nikon

I bought this product during lockdown, I’ve had some really good quality images

I tend to use this lens for holiday as it’s a great all rounder. Close focusing down to around a metre so excellent for butterflies and dragonflies too. Not to heavy and pretty compact but too expensive for what it is.

This lens gives you the versatility to take close ups from a distance and to capture also things at a distance like wildlife.

I've used this lens for over a year now on the A7RIV and A9 Mark II and it's been superb on both cameras. Image quality is excellent, great sharpness with very nice rendering. Autofocus is very snappy and accurate. My only niggle with this lens is that it does not have a zoom lock, and even with the zoom ring set to "tight" the lens does suffer lens creep (zoom extends) when walking around with the camera and lens on a sling strap. Oh, it would nicer if it was lighter too.

I have had this lens for a couple of months now and really love using it. It takes amazing photographs. One of the reasons I bought this lens was because it is so light and I have not been disappointed.

I love this lens, because of its build, quality, reach and size/weight. Not very happy with tightener ring, as the lens tends to drop in or out, depending on position. Also, would be nice having a lock. Ideally would be internal zooming, to avoid all this. Maybe in the next version.

I'm still getting used to it, since I'm not really strong in tele photography, but so far I've enjoyed it a lot. The glass is clear and sharp and the hardware is silent, so it's very convenient for video as well. The only downside is that it's very heavy, but bear in mind it's aimed for professional use (which I am not).

I purchased this lens in March 2021. It performed great the first few times when I used it to take a few shots of the moon (see photo), and a few other shots. I took it on a recent vacation and when I went to use it, I could not get it to focus either in Manual or Automatic mode. The sharpness is no longer there even though I babied this lens, no drops or rough handling. I have no clue as to why, but now I have to go through the hassle of sending it in for repair etc.

I got this lens after asking a friend who has one his reply was "you will not regret owning it". He was not wrong this lens is the best I've owned. It is just outstanding. Sharpe, fast focusing and crystal clear.

So I’ve been using 3rd party lenses for some time and been happy for the majority of the time. I decided having bought a new Sony full frame camera, it was time to invest in a top quality lens so went with my first G Master. All I can say is WOW! The difference between 3rd party and more premium glass is on another level.

I purchased this lens to enable me to capturer things that I was unable to with my previous zoom lens, I have not been disappointed. It is heaver that I expected, however that is also a good thing, in that it's mass makes it more stable to hold however a good tripod is a useful accessary.

Perfect for my uses and tack sharp with lightning focus speed. If you are looking for this lens, don't hesitate. You won't regret it!

This is a considered purchase but worth every penny

Had this lens for just a month and so far it has been outstanding. Fast and accurate with superb image quality, just what I need to take wildlife photographs in any light. Thanks Sony.

I bought this lens few weeks ago. I went out to test this lens today in cloudy day. Took few snaps. What is my impression. Build quality is great. Doesn't feel heavy in hand but eventually you feel it. As paired with my A7R4M its cumulative 2kg. 1.4 kg from lens.Lens zoom part relapse if set on smooth. However if you turn ring towards tight it hold well. Focus is quick but if you have used GM lenses you may feel its not quickest .I think 200-600mm G OSS and 70 to 200mm GM OSS are faster. Works well at 3ft distance in case you wanna shoot something up close. Optics are sharp, but not as sharp as 70-200mm GM OSS.Low light performance is reasonable. Bokeh is creamy. Lens produces superb detail. Noise is very little on high shutter speed even in low light and hand held.Colour reproduction is excellent. When I compare image quality with my SONY FE 24-70GM or FE 70-200GM I feel that its a bit less sharp in detailing. Very difficult to quantify. Its not that its not sharp. Its a great lens I dodnot experience chromatic abrassion. There was no vignetting.Corners maintains sharpness.I have not shot a very tall linear building hence cannot talk about linear distortion. Although it maintained alignment and sharpness when I covered a wide brick wall.Unfortunately I deleted those image. For wild life many times I felt like missing my 200-600mm. But I changed to APSC mode and it was on job again. I didnot felt any loss of quality.It wins on its small length. One can pack 3 lenses and go. As it all fits in small backpack or camera bag unlike 200-600mm G OSS. What is my final opinion, Yes I would buy it, but price is hefty. I would like it to improve at par with FE 70-200mm GM lens. Here I am attaching you few pic from my todays shoot. I used apple photo to edit it. Please leave your comment for me to look into your experience. Its my early review.Thanks for read.
