SEL-2470GM

While the size and cost of this lens can't be ignored, the quality and versatility also stand out. I normally post pictures, but there are already tons of sample pictures out there.Pros- The image quality is excellent and paired with the A7RIII, I was able to get some really great shots- The build quality seems very sturdy, and my copy of the lens seems to be very good (which may speak to quality control by Sony)- The zoom ring is quite firm, which keeps the lens from creeping.- Nice to have the zoom lock feature when you need it- Nice and sharp wide open, and throughout the zoom range (You can see a difference wide open at the end of the zoom range, but the photos are still very good)- After shooting a little with this lens, and taking about 100 pictures, very few of them had any chromatic aberration. In post, I only needed to correct for this in a few photos.Cons- The size and weight are quite significant, and pretty much take away any size advantage that the mirror-less A7RIII might have had over another DSLR- The focus is by wire, so you don't get the same smooth focus-ring feel.- While the A7RIII has IBIS, I would really like to see image stabilization here for the cost and size- Speaking of price... $$$ConclusionIf you are looking for a pro lens, and don't mind carrying it around, then this lens is great. Extremely sharp for a zoom and correcting any chromatic aberration, or lens distortion was easily handled in Lightroom. If you are looking to get a standard zoom for your Sony mirror-less, this is a great option.

Sony has really set a new precedent with their GM glass and this really showcases it. They've somehow figured out how to encapsulate all of the desirable optical qualities you'd get with a very good prime into a zoom.Previously, I wouldn't have even considered shooting a zoom for anything really important, but this lens changed all that. Even the bokeh is pleasant and very usable.It's great not having to lug 5 lenses around with me everywhere I go and risk getting dust on the sensor when I'm changing them. It's also refreshing having the freedom to focus solely on the photography side of things without having to worry about the equipment.I've heard people call this lens heavy, and it's no lie. It is is among the heavier ones I've used. You can feel the quality of its construction in it's sheer density and mass. With the grip, it's not badly balanced, but without it, I don't know how I would manage it. That's really the only caveat that comes with this lens that I've found so far - you've got to possess the strength to wield it.Autofocus is very fast on my A7rii, but insanely fast on the A7riii. the colors are very nice, a bit on the cool side, which I prefer, and contrast is excellent. It's also a very sharp lens, even at f/2.8.I also own the 28-105mm G now and I'd say this one is a bit better optically, at least to my taste. If being able to push the bokeh further and having that extra 1.2 stops of light matters to you, I'd go with this one. If having the extra range and a slightly lighter lens is a top priority, then opt for the 70-105. Or you can always buy both of them, because they're both amazing in their own ways. Lol

I mean, WOW. I am seriously in love with this lens. I’ve used many lens brands in the past, which include the stock Sony lens which came with the camera I purchased and a Sigma lens. NOTHING COMPARES TO THIS ONE!The Sony G Master series is by far out of this world. The crisp photos are perfection. I’m in complete awe. As a photographer and business owner, it is so important to have the right products. This camera has blown my work out of the park and makes me stand out as a sole photographer.I’ve attached some photos for reference!

First impressions of this lens are really good.I've done some test shots comparing against two other lenses in the focal range.Comparing against the Sony 28mm with 16mm conversion lens and with the Zeiss FE 35mm F2.8 lens (my favorite)Attached are a couple of test shots – nothing too special, I'm not DxOMark – check out their review when they get to it.Pros:- Solid Build – the high quality you'd expect from a GM lens.- Surprisingly light – I have this mounted on an a7rii and it doesn't make the camera too front heavy.- Has an 82mm filter thread – When you're getting down to 16mm it gets increasingly hard to find lenses that don't have a bulbous front element preventing a filter thread.- The Bokeh this lens produces is beautiful – not as noticeable in the lower focal ranges, as you'd expect. But 35mm gives an even smoother depth of field than my Zeiss 35mm equivalent- F2.8 at 16mm is impressive – For such a wide lens having the option to let in this much light is hard to come by.- Very little distortion – even without correction there is surprisingly little distortion on this lens.- Weather sealed!Cons:- The lens does extend when you use the wider end. Not a big deal, but it would have been nice to have that contained in the body.- It's not small, but that's expected from this.- When you use this with a filter, you will get a little bit of a vignetting from the filter – since the angle is so wide. Somewhat expected, but kind of a bummer. Even with 2 filters stacked, it's not noticeable above 20mmNot much bad to say about this lens. It's incredibly sharp and performant, while not feeling like a burden to carry around.
