Sony FE 20-70mm f/4 G Lens (Sony E)

The images from this lens are razor sharp wide open. With a good digital camera you don't need 2.8. The one stop higher iso's difference is not noticeable. Boquet between F2.8 to F4 is not that noticeable either. On top of that you have a substantial weight, size and cost difference. Image quality is stellar. The reviewers love this lens and the only thing they nit pick is distortion at 20mm. It kept me from buying it at first but after owning it it is a non-issue for me. Having been a pro photographer for 30 years I am very picky when it comes to good lenses. This lens is another keeper.

This lens is a winner. I come from 30+ years of shooting nearly every brand out there, from Nikon to Canon to Fuji and now Sony. These systems are all quite good these days, and it's mostly a matter of what features you value most. For me, I value FF for image quality, high ISO capability and light weight. I'm currently using this lens on the A7R V.After years of using f/2.8 zooms, my needs have changed and love what Sony is doing with f/4 zooms. They're a really interesting package in terms of features, size, focal length and weight. I was debating between this 20-70 and the 24-105 and having shot 24-105 on Canon FF for years, I decided that the size and weight savings of this lens was something worth trying out. I don't regret it at all.With f/4, you lose one stop of speed, but with excellent high ISO on modern cameras, it's less of an issue these days. What's innovative is that this zoom breaks the traditional mold of 24-70 or 24-105; at the wide end, the extra 4mm give you an extra 10 degrees field of view. To me, this is far more useful than 15-20mm on the wide end. When cameras have 40-50MP of resolution, I would rather have 20mm and capture more, and if so, shoot Super 35mm to turn 70mm into 105mm.This lens really nails it on many fronts. It is very compact, lightweight and focuses very quickly. I paired it with the Sony A7R V on a trip to Japan and it performed flawlessly. When you're shooting landscapes or indoors, the extra width that 20mm gives you is really handy. I grew up shooting aperture priority and continue today; having the aperture ring is really nice and lets you quickly slide it to wide open when you go indoors. Much quicker than using camera body dials.From an image quality perspective, the lens is pretty sharp. There is some distortion at 20mm and some vignetting in the corners. That is to be expected in a zoom like this and can be corrected in camera or in post. Not a huge issue. Color rendition is good and works well with Sony's color science.Overall, I recommend this if you're interested in a lightweight walk-around lens that is easy to live with and won't weigh you down.

For years I've wanted a lens like this one that goes to 70mm but also covers a wider angle than virtually any other short zoom I've heard of. It has turned out to be just as good as I'd hoped. When I shoot landscapes I often want the widest view possible (not always, of course), and this one does it. It's also fairly light and easy to tote into the backcountry. I took it to Costa Rica recently for a 12-day tour that included 10-miles-per-day hiking about. The camera-lens combo, tucked into a waist pack, allowed me to carry a long lens on another camera and still get virtually any non-wildlife photo I wanted with ease. Great addition to my collection!

There's no doubt I'm a Sony fanboy, I have perhaps 15 bodies and lenses (mostly GM and R series bodies). Modern lens designers have done a fantastic job in creating high resolution, contrasty designs with edge to edge sharpness that are well matched to high resolution sensors. It's hard to find a poor lens today. The new EF 20-70mm F/4 G falls within this category, with a few caveats. My main criteria for choosing this lens is to supplement my older EF 24-105mm F/4 G lens with a lighter walk about lens that is sharper and less obtrusive for street photography. This new lens does so almost perfectly. As other lens reviewers who provide a more technical perspective note, the EF 20-70mm lens does vignette at its widest field of view, has enormous distortions, and it doesn't have image stabilization, but these are almost perfectly corrected by the in-body software, so not really a problem. Lack of Image stabilization isn't really a problem in wide angle and normal lenses, and most modern Sony bodies have IS built into them. Overall this is a near perfect travel lens, it's light weight, has excellent optics, and provides an ultra wide to short telephoto field of view. Do I wish it had a F/2.8 aperture? Yes, but not at the expense of weight and size.

I bought this for my a7c and it is amazing. Gorgeous images, excellent ease of use, just about perfect as a general-purpose zoom. A bit heavy and large, though lighter, smaller, and cheaper than the G Master 24-70. I love it.

This is a really great lens. It has a very useful focal range, excellent image quality, and it is not too heavy or big. That said, I'm disappointed Amazon is unable to continue the DPReview.com website. I've been a member there for 18 years and make all my lens purchases on AMZN due to info and reviews I've read on that website. This lens is highly recommended.

This is a fine lens but has a very limited zoom range. I was able to return it for a refund and buy a 24-105mm zoom which is much more practical.
