I have just finished my quick custom testing of real life performance of Sony G 20-70/4 versus Sony G 24-105/4 on Sony A7R4A.Openly speaking I feel a little bit disappointed with 20-70/4's IQ.I expected clearly better overall rendering throughout the zoom range.What I saw was only crisper and sharper broader center between 24 and 35 and crisper and sharper image across the frame from 50 to 70mm.24-35mm border/corner IQ was nothing to write home about.Same with 20mm.

I like 20-70/4's size,weight and manual aperture ring,but I found it not better enough to replace my 24-105/4 G.

I bought this lens to use for my travel kit and so far I'm pleased with it. Corner sharpness could be better but that's something I notice when I pixel peep and zoom in a lot. I do enjoy the size and build quality and the overall feel of the lens, but it seems to expensive for what it is. At least in Germany.

I plan on using this lens and my 35mm GM for my next vacation.

Going through a few more shots from the first trip with the 20-70. Handheld at 1/30th in a dark cavernous room full of sherry casks. I guess the F4 isn't that big a deal. I was a little hesitant about that aspect but no longer.

Just sold the 17-28 2.8 last night. Great lens but it required having a longer one along for the ride.

The overall flexibility of this lens eliminating lens changes makes it my favorite casual glass so far.

Does anyone know the actual focal length at 20mm setting? Is it less than 20 or slightly more?
Thanks

I have the 20-70, as well as the FE 20, the FE 12-24/4 and the PZ 16-35/4. I've not made any effort to make a careful coverage comparison at 20mm focal length.

What I can tell you, however, is that for lenses designed for software correction of distortion and vignetting, generally the design goal is to have the final angle of view equate to the lens' marketing spec after all software corrections.

Occasionally you will see users comment online that some lenses appear wider than what they are marketed as being, but it's rare to see those comments include whether this was observed before or after software corrections.

Not sure if this helps, but I hope so, at least a bit.

With such huge distortion at 20mm uncorrected you get quite a bit more than 20mm if you are correcting manually

As the price went down from 1875 to 1400 USD equiv,I decided to go for 20-70/4 G.Unfortunately I had to return it as it was heavily decentered.The large upper right corner,roughly slightly more than 1/9th of the picture area was soft wide open and mushy stopped down to f8-11.No cure.

The lens was recently launched and such a f..k up right away at the beginning.Hm....disappointed a little I suggest everyone to check out these lenses for lemons.

Thatís the first thing I do whenever I get a new lens. Mine is nicely centered, and I imagine almost all are. Iím sorry yours wasnít, but no one should be discouraged from buying one. My copy lives almost permanently on my A7RIV.

I got this lens few days ago and mine is centered as per Fredís test.

Had a hard time deciding between this or the 16-35/28-60 pair and making up my mind for selling 20/1.8. 16-35 has a similar MTF but 20 could be little sharper at F4, for landscape use. All these lenses are a notch above 24-105 for sure, which also is nice at F8.

The lens is 19mm at the wide end which makes it 28.5-105mm on APSc.

My copy is sharp as expected.

Yes of course. I was a bit worried reading the reactions but it is what the reviews say, very sharp lens indeed, a step up from our beloved 24-105. I will use it when travelling and also landscapesÖ

Its truly a one lens solution, and you end up shooting everything with such lenses out of convenience and regrettably, at the expense of perfection.

But the trade off is now not so much as was the case with 24-105.

I just pulled the trigger on this lens as it seems to check several boxes for me.

The 20-70 will be much lighter and an easier carry over the 24-70 GM II and 20 G with no lens changes. I also like that it has a a 0.39 magnification factor. It should nicely complement my 35 GM and 70-200 GM II.

I don't need anything wider than 20mm, so I don't need any other ultrawide. If for some reason I do, I will pick up the inexpensive Viltrox 16mm.

I'm far happier with the FE 20-70 than I ever was with the FE 24-105. I originally sold the 24-105 because I found it just a touch too large and heavy, and started to look at the 20-70 because it was substantially lighter, and also because of the 20mm at the wide end.

I also find the color and contrast to be better.

Potentially can replace 3 lenses:

16-35
24-105
20 G

(Total 1.4-1.5 Kg of weight)

A fast 14 should be a good companion to 20-70. It will be a still fast 21mm on a crop body.

I just got mine today, and first impressions are great. It is about the same size/weight as the 35 GM, and these two will pair great together. Seems very sharp, fast and accurate AF on my A1, and it can focus very close.

My 20G and 24-70 GM II are on the buy/sell board. It will be hard to let either of those lenses go.

There was a collectors' car show in our little town of Sidney today, here are a couple from a brief walk about this morning.

Note the last one is a shot of a prop very cleverly put together and positioned by the car owner.

Iím thinking since now I have a APSC kit that for my A7RV with the Sigma 28-75 which now is not wide enough at FF this maybe a option with my A7RV and 70-200 with this 20-70 might be a nice FF setup. 28 is not wide enough or go 24-70 maybe Sigma instead. Have to think about this. Hate going to a F4 and give up my 2.8 but wide is wide and 20 is better

I am pairing the 20-70 G with the 70-200 GM II and really makes a nice pair. I also have a 35mm f/1.4 GM if I need faster than f/4.
