Hi Bro, I have both lenses and have to say that the GM II is specially designed for Low light F2.8 + the best Bokeh effects with corner to corner sharpness at F2.8 throughout its entire focal range. Hence, This part GMII beats the 20-70mm hands down, as the 20-70mm F4 does not have that feature/design and not meant to be, which is an important point. The two lenses are designed for different purposes. Also, I think in your comparison, if you shoot at F8-11, at this aperture, the Image would be definitely similar. In fact, if we shoot at F8-11, most good lens will produce similar results, and the difference will be minimal. As at this aperture F8-11, it's not the "difficult" part of lens design.

Probably the most comprehensive review that I have watched in respect to camera+lenses. I am very impressed with the clarity and sharpness of the 20-70mm f/4 when compared to the much more expensive G-Master lens. The only thing that I would have liked to have seen in your sample images would be daylight shots of a variety of subjects and conditions. Obviously your night shots were taken with the camera mounted on a tri-pod. I would have liked to have seen some examples of "hand held" shots taken under varying lighting conditions but basically you have "sold me" on the performance of the 20-70 f/4. I am wanting to go from Canon to Sony and I believe your video has solidified my decision. I would hope this lens (the G lens would perform equally well mounted on a Sony Alpha a7 Mk IV, the camera of my choice (and within my budget). Thank you my friend for this fine critique.

I have exactly this combo of lens and camera. The only thing to be aware of is that the lens is a little soft around the edges at 35mm. Stopped down to f11 at this zoom range and it becomes acceptable.

i think the 20-70 f4 with a 85mm 1.4 or something like that would be the perfect pair for travel.

Finally a review that actually provides a concrete example of what you could accomplish with these lenses and camera, not just talking about specs that can be found elsewhere. You are a VERY talented photographer., the pictures are incredible sharp and well composed. For the NY shots, did you do any of them manually or used tripod always ?. I 've just bought the A7RV (could not pass the B&H offer of 400 off to the price) , I already have the Tamron 28-75, a great lens too and several GM primes, never considered buying the 24-70 GM for its price and weight, this 20-70 looks very tempting, in particular for its low weight and corner to corner sharpness. I've just subscribed to your channel and will take a look at your video with 50 tips for the RV .....well done !!!!....oh, one more question . the video at he start of the 24-70 demo, was that an 8K with the RV?

First of all: thank you very much for the great information and the great video. Does the tube of the 20-70 f/4 lens extend when you hold the lens downwards? Kind regards. (Ah, ich glaube Sie verstehen deutsch 😀)

Did you choose one over the other or own both? I have the 24-70mm GMii but use that for more pro work. I am looking to trade my 16-35mm f4 PZ for the 20-70mm as a pure travel lens. A little size and weight saving and just the one lens to take - possibly with my B camera A7cR.

Hard to choose 🫥

Very good video, super photos!

I’ve watched a lot of your videos and they are very educational. I have come to enjoy the SL2-S. I’m not a professional, but enjoy taking photos and doing training videos. Recently I sold one of my SL2-S’s for a Sony FX3, just for efficiency purposes of videos. Considering selling another SL2-S and getting a Sony A7R5 as a hybrid. I was wondering your opinion if that would be a good idea? Thanks so much. Keep up the good work.

Would you recomend this over sigma 24-70 f2.8?

You are shooting a landscape, in such conditions there is not much difference, but if you shoot a report and there are people here, the difference will be visible

More a7rv and 24-70mm gm ii pls 🙏

Were your samples photographed in-hand or on a tripod?

The NY photos looked great & pretty sharp but have to say, NY needs to be done with your Leica M camera. 😊

I just got the 24-70mm GMII. I've only used it for 5 minutes but right away I can the difference in size and weight. I can also tell that the 20-70 was sharper wide open at f4 vs the GMII at f2.8. The GMII also has some chromatic aberration at f2.8. If you stop it down im sure this is a non-issue. I'm going to be testing it this next week and I'll know more.

Great stuff

The 24-70 f/2.8 by Sony vs Nikon Z, which is superior, and which do you prefer?

Great review. I just got 20-70mm. I am using on sony a7iii. Its little dark in low light. I am thinking I need to upgrade by camera body, what you suggest. I am an amateur photographer.

Although I am not interested in Sony and Sony lenses I enjoyed the shots, in particular Singapore and in combination with that music made it a great experience. Just talking about you this afternoon with a fellow photographer about your Giga pixel shots. He wants to do the same thing for a promotion shot so I will send him links to your videos on that subject so he can have peek on what's possible. Thanks for sharing the "goodies" and a have great weekend !

Schweizer?

Well explained and great video . Am full time Nikon shooter that ventured into the Sony system with the A7iv ,but is disappointed with the color rendition . Am a very experienced shooter and working with Sony on people of color is a huge problem. I have tried lots of raw developers and the problem exists . I have finally decided to get done with the A7iv,I was told that that exact problem was solved on the A7RV. That the A7RV white balance was greatly improved . I really want to know your view as someone who has shot with all these systems . Thanks in advance .

16-35gm and a7rV how to aps-c crop mode :) thank u
