Only negative is that there is no zoom lock to stop lens expanding when you carry it over your shoulder.

Very impressed with the results obtained with this lens. It’s compact design and light weight were additional features that swayed me in it’s the purchase.

I have only had this lens for one month but cant take it off my camera, its small and compact with a great range. The lens performs well at all focal lengths and is sharp across the whole image, I swapped my 24-105 to this lens and it has been a game changer, the extra 4mm width is amazing, its so sharp cropping in to compensate for the reduced max zoom isn't a problem. If you want a sharp. lightweight lens this is the one.

Bought the 20 - 70 f4 recently, having owned a Sony 24- 105 f4 for some time. The new lens is superior in my opinion in all regards. Resolution and contrast is top notch. Remarkably, at 20mm f5.6, it gives the acclaimed 20mm f1.8 at the same aperture a run for its money with quality virtually indistinguishable. Autofocus is spot on and reliable. Weight and size are perfect for an A7 series body.

The only negative for me is that there is quite strong field curvature at the wide end. This is only really something you have to consider for distant shots such as landscapes where the focus plane can be closer at the edges than the centre of the frame This is largely resolved by making sure the you focus the center on the most distant point in the frame. To be clear I am not referring to the barrel distortion that is corrected either in camera on jpegs or in software from raw images. I am not at all bothered by this and it is completely corrected for all but the most critical applications. Overall I would highly recommend.

A great all-in-one lens for general day-to-day photos and especially useful for travel on a Sony A7CII. Really good resolution under most lighting conditions. A slight amount of 'noise' is noticeable when 'pixel-peeping' when used in dark interior setting but that's not surprising given that it's an f4 lens.

Not used it yet for video so cannot comment on this aspect.

Highly recommended given its size, weight and focal range.

Bought this for use when travelling good single lens

This lens is a good travel lens is very versatile the wide at 20 is enough at 70 you can use crop for a further zoom . Is a very light . Would have been good if can get this lens at 2.8 but then it would be less portable

I have been using this lens for over 9 months now and have been very pleased with the results. It produces very sharp images and covers most of my general photographic needs. The extra 20 mm wide angle helps me capture those dramatic landscapes and images are surprisingly crisp and sharp for a lens in this price bracket.

It’s also my ‘go to lens‘ for when I go on holidays

This lens certainly lives up to my expectations, 20mm at the wide end is such a bonus on an all in one travel lens. This is a very versatile, very sharp, reasonably small, well designed, well made Sony "G" lens.

This is a sharp detailed lens, robust and well made, which is excellent. I have however only given 4 stars due to the excessive distortion wide open 20 - 24 mm

So glad I bought this lens on a recommendation from a friend, it’s everything I need in a 20-70 for my landscape photography

I purchased this lens for my broadcast work and am pairing it up with an FX6. Having the extra 20mm is really great for filming observationally. It's far more dynamic than the 24-70GM II. Also the 20-70 is virtually parfocal which is essential for my work. The 24-70GM II is not parfocal which is the reason I would never buy it. Also, the 20-70mm is super light and the image quality is fantastic. So, I don't regret moving away from the heavy Cine Zooms I've been using for years. One thought! I'd happily accept a little extra weight for a F2.8 version of the 20-70mm as long as it remains parfocal. And internal zooming would be a lot more reassuring. Another related point for Sony to consider, being able to allocate Clear Image Zoom to an Assignable button on the FX6, (you can't currently do this), would be incredibly useful in terms of being able to quickly extend the range of this lens at the tight end when you need that little extra bit of reach. It should be easy to add this to the upcoming FX6 update...and why not make the FF/S35 menu option assignable too!? Not being able to allocate these two features to Assignable Buttons really slows down my shooting work flow.

Really like this new lens. I take a lot of landscape photos and find the new 20 to 70mm zoom range excellent. Photo quality is gorgeous and the lens quality excellent and its feature rich. This lens replaced my 24-105mm. The 20mm vs 24mm makes a big difference landscape wise & means less lens swapping for me. AlsoI very much appreciate the fact that the 20-70mm is much lighter and in my view takes better photos. I’ve owned this lens now for over 2 months and so far I’m extremely happy with it.

So happy I bought this to work with my new ZV-E1. Only after two weeks I am still exploring the great features of this product.It so light and versatile, and not only that but the zoom and focus on this is amazing.

I replaced my excellent FE 24-105mm G lens with this new 20-70mm lens as its range is more in keeping for my use in travel, landscape, children, reportage and ad hoc portraiture photography after reading reviews and trying one in my local store. It's Image Quality is fantastic and being more compact and lighter than my 24-105 will be more useful and thus stay attached to my A7iii most of the time. Well done Sony, you have produced a real gem of a lens with this one.

After using the lens I've found it very sharp from F4 all the way to F11. this is perfect for what I bought it for, Landscape & Travel. The lens is very light and small making it perfect for both those types of photography. If you don't mind the high price it is well worth the investment. It's another G lens with GM quality at half the price! look at it this way and you will be happy. This one's a keeper for me.

Light weight, good functionality, and excellent images.

Just what I needed! It's very flexible bit of kit, great range of focal lengths and very easy to handle because of its modest weight.

Using this lens on a Sony A7r5 and lens is sharp edge to edge even at 20mm and build is like GM lens. Great walk about lens.

Two weeks in and I am yet to find any real annoyances with this lens. So far it is the best every day travel / landscape zoom I have found. Ok the bokeh is not lovely, but at 70mm f4 it is acceptable for most everyday use. Combined with an A7c this is the most versatile lightweight solution out there. Well done Sony.
