After a full day of shooting, my wrists and back don't hurt since this is light for this class of lens.All in all, I love this lens, and will use it for all my professional (and maybe even casual) shoots.

I found that the first version focus hunted in lower light situations and had focus motor noise. Not really annoying, but it was definitely there. The new focus speed (which is instantaneous) and the complete silence will be welcome indoors during commercial and photojournalism shoots. My wedding pro friends will certainly appreciate the quiet and the much better low light focus performance.The continuous focus keeps up with my a1 at 30 fps. The previous version did not. Not even close. Big plus.Is it worth replacing your first version? That's a decision based upon if the faster and quieter focus is worth it to your work flow. For me, it really is. If you do not already have version 1 of the 24-70 and you are looking at the price difference - get version II. You won't second guess the decision.Are the version II improvements in the 24-70 equal to the improvements in the new 70-200 f/2.8 GM II? Probably not - but in that case, the new smaller size and weight in the 70-200 really matter. In this case, the rather modest size and weight shaves are just a small added bonus to a great new lens.Short answer: Outstanding glass. Get it.

Taking out any evaluation of the optical improvements (of which there are many), this lens is a functional marvel. The iris ring that can be de-clicked with the touch of a switch, the smaller size, lighter weight, and ability to adjust the speed of the zoom ring are massive improvements. These aren't just cosmetic, and can't be overstated. It's game changing when you're filming for 18 hours doing handheld or monopod work. You want to carry as little as possible, with as little sacrifice to the quality of the glass.From what I can tell, the glass is extremely sharp, corner to corner throughout the entire zoom range of this lens. The bokeh also looks better to my eye, and matches better with my 70-200 GM ii. This upgrade hasn't gotten a lot of love, for some reason. ... MoreTaking out any evaluation of the optical improvements (of which there are many), this lens is a functional marvel.

Maybe it's because the 24-70 i was a decent enough lens- no argument there. It was good. But this is great. If you do documentary work you'll love this lens. If you like buttery bokeh and a substantially smaller form factor, this is for you.

I bought this lens mainly because I needed a Fast Wide Angle Lens (Faster than f/2.8) with minimal distortion and chromatic aberration.First, the optics of this lens are comparable to the Sony FE 24mm f/1.4 GM.Second, the angle of view seems to be appropriate for most Wide Angle needs but it is particularly well-suited for those who want a blogging lens - since this one gives you a few extra degrees of view where you can comfortably fit your face.Third, the Autofocus is fast and accurate, except under very special circumstances (like low light).Forth, I love this lens for those situations when I need minimal weight (i.e. when I'm hiking in high altitudes and every extra pound feels like a ton). For this reason, it is also a great lens to be used on a Gimbal ... MoreI bought this lens mainly because I needed a Fast Wide Angle Lens (Faster than f/2.8) with minimal distortion and chromatic aberration.First, the optics of this lens are comparable to the Sony FE 24mm f/1.4 GM.Second, the angle of view seems to be appropriate for most Wide Angle needs but it is particularly well-suited for those who want a blogging lens - since this one gives you a few extra degrees of view where you can comfortably fit your face.Third, the Autofocus is fast and accurate, except under very special circumstances (like low light).Forth, I love this lens for those situations when I need minimal weight (i.e. when I'm hiking in high altitudes and every extra pound feels like a ton). For this reason, it is also a great lens to be used on a Gimbal or other kind of support devices used by video creators and bloggers.Fifth, I really appreciate its capability to get very close thanks to its minimum focusing distance.Finally, the Bokeh is not as 'creamy' as the Sony FE 24mm f/1.4 GM but it is absolutely satisfying nevertheless.One minor disappointment about this lens relates to having a very noticeable 'lens breathing' effect. So if you are into pulling focus on videos - you will need to deal with this minor limitation.This is one of my favorite Sony Lenses, I own and use almost all of the GM series, except for the Super Telephoto ones.I will soon travel to Bolivia's Uyuni Salt Flats where I will be able to test this lens for Low-Light and Astrophotography.
I purchased the original 24-70GM when I got my first Sony in 2017. It was quite wonderful and compared well with my former Nikon 24-70 but it was HEAVY, noticeably so. Nowadays, I usually use primes for my serious work but wanted something more flexible for travel, granted at the cost of weight, bulk, and speed. My travel gear has been the 24-70, 85 f/1.8 FE for my people photos, and the 70-200 f/4 for longer images. Those three together weigh just over four pounds, not too bad.When I received my new GMII 24-70 I did my usual tests, a la Fred Miranda. I compared it to my primes in that range, the 24GM, 35GM, and 50GM as well as the manual focus Voightlander 50 f/2 APO. The primes were better than the 24-70 but not by a lot except for the 50 f/2 APO which easily ... MoreI purchased the original 24-70GM when I got my first Sony in 2017.

The primes were better than the 24-70 but not by a lot except for the 50 f/2 APO which easily surpassed all the other primes and zooms I've ever used. The GM II is a bit weaker in the corners than the primes but at the center, it's really hard to tell, even with pixel peeping at 100%.Overall, I'm rather pleased with this lens. For longer hikes when I don't want to carry a lot of weight, the 20G, 24-70GM II, and the 135 f/2.8 Batis make a formidable landscape grouping.
All the rave reviews for this lens are true. It truly is superb. The only drawback is its relatively high price. The question for me was is it worth the upgrade from the older Zeiss 35/1.4? It is smaller, lighter and sharper than the older lens which I also own. I think I got one of the later good copies of the Zeiss 35mm f1.4 (earlier copies seem to have been plagued with quality control issues). Certainly at 100% magnification on 50 mp and 62 mp sensors, the GM is noticeably sharper and higher in contrast wide open but the difference is not huge. In normal use I think the image quality from the older lens is more than sufficient. You can do a little sharpening in post processing if you want. I decided to go ahead and purchase the GM but if cost were a limiting ... MoreAll the rave reviews for this lens are true. It truly is superb. The only drawback is its relatively high price.

You can get them used now for a bargain.
Sharpest, fastest, most accurate 50mm lens I have ever used from any brand. You can use this lens at any aperture and get sharp results that will not disappoint. I was gob smacked as they say, about how sharp and clean it is at 1.2 across the frame.The most critical reviews I saw about this lens in my view show how good the lens is.Those critiques were that it was far too perfect in image quality and that the lens doesn't change character when you stop down, meaning that the only real benefit you are going to see is increasing the depth of field when you stop down. So if you prefer the various looks (AKA obvious defects wide open that lessen on stopping down) of other 1.2 lenses like the Canon 50mm f1.2L EF, don't buy this.My most critical issues with the lens ... MoreSharpest, fastest, most accurate 50mm lens I have ever used from any brand.

However, every other 1.2 50mm I have seen better in these regards is either way larger and heavier, doesn't have auto focus or the AF is not nearly is fast/accurate, or the IQ isn't as good. So its basically a trade off here.I would say that unless there is some revolutionary change in lens design that happens soon, you will enjoy this lens for a very long time without the need to upgrade when a version 2 or even version 3 come about.
This lens instantly turned my videos into something spectacular. If you were looking for a lens to make your content stand out...this is the one. It is my go-to for making eye-catching visuals. No other lens captures a scene like this one.The low light performance of the A7S3 plus this lens, makes the most amazing low light captures look like a Hollywood film scene. It's that good.The lens is lightweight and compact. Just this lens alone, I can get about 80% of an event captured. The rest are just tighter or telephoto shots. I did a lot of research before getting this lens because I needed one to capture groups and close-quarter wide angles, especially in dark-lit places...like wedding after parties.

I got the chance to test out this lens versus the famous Sigma 24-70 2.8 DG DN on my a7rV. Shot side by side with the same scene, same settings, focused in same areas the GM II was consistently doing better than the sigma. It was especially noticeable when shooting wide open. The GM II was displaying better micro contrast, resolving better than the sigma in the center and corners. This was more noticable when shooting distant objects, focused at infinity which I often do for landscapes or at hyperfocal.Colors wise the sony render more on neutral side where the sigma is more on warmer side. Is the GM II 2x better than the sigma for the price? That's for you to decide. Maybe not but overall what you are paying for here is the AF/ergonimics/size/weight and great ... MoreI got the chance to test out this lens versus the famous Sigma 24-70 2.8 DG DN on my a7rV.

To me the sigma has annoyed me the past with missing focus during critical moments during events which caused me having to reshoot but missing the better moment.Also please take into consideration sample variation because I had to go through TWO copies of the GM II to get this excellent one which is NOT FUN. Copy variation plagues the 24-70 zoom lenses in particular as they are difficult to design and have different tolerances. I was not happy with my two previous copies as they were softer on the left side of the frame even stopped down at most FL which was not OK. I had the same experience when I got my sony 12-24 GM lens. I really wish this wasn't the same case in 2023 but here we are.Still highly recommend this lens if you can afford it and want the best AF especially.
Near Perfect but let down by Sony camera’s limitation.I only had this lens for more than 2 weeks. I have been testing this lens ever since I received this.In a short test period, I would say this lens performance is good in areas:1.Wide end image quality: Good.2.Tele end image quality: Good (but pay attention to shutter speed to reduce blurring due to shake).3.AF acquisition and final focus result: Good (there is slight focus breathing when you change focal length and re-focus).4.Handling: Good, balances well on camera (I use A1).The only area I’m a little critical is non-OIS in lens. The Sony camera I use is the A1 and it has IBIS but it’s certainly not that effective in the Tele end. I must increase the shutter speed to minimize shake, and this ... MoreNear Perfect but let down by Sony camera’s limitation.I only had this lens for more than 2 weeks.

The Sony camera I use is the A1 and it has IBIS but it’s certainly not that effective in the Tele end. I must increase the shutter speed to minimize shake, and this limits my use case. Sony should either improve the cameras (A1) IBIS effective stops or include OIS in lens. The Focus breathing issue might not be an issue if you have newer released Sony cameras after A1 release. The new cameras have focus breathing compensation. Sony should improve/add this in A1 or build lens with better focus breathing handling.But from an Image quality point, the G2 is certainly better (not a huge amount but slightly) than other 24-70mm F2.8 lens.
