You mentioned the balance is good... how's it compare to the 24-105? How smooth do the mechanics feel (i.e. smoothness and damping of the zoom ring)?

the zoom ring is very smooth and feels very nice and precise, but turns the wrong way 
. Dit not compare it yet but can tell you that close focus is nothing to write about.
It was better then expected, like the rendering of the 2.8 and it is sure sharp enough on 24mp. I took the middle picture also at F8 and it was really sharp. All the branches etc. Don’t know if you could see the difference at 1600px though. I can place a 100% crop of the f8 picture if you want.
It is not ment to replace my 24-105.
For less weight you gain one fstop but loose ois, versatility in range and close focus.
But you don’t need those things all of the time and just want something lighter and good and a stop more light and less DoF.
Like it better then the 20-60. Feeling and f-stop. 20-60/3.5 would be a dream lens .

Would love to see some 100% crops!

here you go. For the middle foto I took the F8 version. The other two are the same, 28/2.8 and 70/2.8
Because of the detail of the image with all those branches in focus, the 100% jpg after raw conversion was 30MB, to get the crop below 1MB I had to save the picture with like 60% quality
Thanks, that's helpful!

Your eyeing one as well?

I'd have to wait until there's money in the bank account. ^^;; But yeah, a nice lightweight zoom is tempting.
Not immediately, but I could certainly see it as a light alternative to the 24-105, which I do have. I also have the 24-70 Art, so the 28-70 kinda gets squeezed. But it sure looks like a fine lens.

It's better than fine, from the pic's I've shot with it. And occasionally posted

Compared to those lenses, the 28-70 has the best quality per gram
, and best quality vs price (=value). The quick test yesterday assured me that it is very good straight from 2.8, on a 24mp body. Markus pictures already showed that.I’m now starting to question my current primes. In most cases 2.8 is fast enough and 1.8 give me just 1,33 stop iso gain. So iso 4000 instead of 1600. (If I’m right) I think the s5ii can handle that. I used the primes as light walk around lenses, that function could be overtaken by the 28-70. But a prime lens is also nice for walk around and I like that challenge, my pictures tend to be better composed with primes. So I see myself trade in these primes for one faster prime. Probably a Sigma 1.4 dg dn. But then comes the question which one
.

Ha ha. Me too. I sometimes wonder about my Lumix 85mm. The 28-70mm has pretty much got that covered, for how and what I shoot. The 50mm is a no brainer for me - I could shoot a whole car/bike show with just the 50mm.. I've got to remind myself to use another lens just to get a bit of variety in my shots. And that's generally an ultrawide.I’m now starting to question my current primes. In most cases 2.8 is fast enough and 1.8 give me just 1,33 stop iso gain. So iso 4000 instead of 1600.

I've actually eyed off the Lumix S Pro 50mm F1.4 a couple of times, when it's been on sale. But the size and weight generally dissuades me on that. A good sidegrade would probably be the Siggy 50mm F1.4 Art. Not too excessive in any measure. But there's just something about the Lumix 50mm 1.8 that I really really like, making it quite difficult to move on from lol lol.
One thing's for sure though, the 28-70mm is going to remain part of my travel kit. And it's not often people say that about a 20 something to 70mm F2.8 full frame zoom

I think I will go for either the 24 or 35 1.4 Sigma. And keep the 50, no point of selling it. It will give me max 200, 225. For that money I will keep it myself.

From my samples this morning I noticed that landscape + 2.8 is a bad combo for heavy vignetting with a blue sky, but also the foreground left lower corner is clearly visible. And not really well correctable, and worse when close focussing. Example:
Focused on tower, 5.6 vs focused on the foreground at 2.8
For me this is fine, but a trade off for the size. And I think for this particular shoot this morning I would have been better of with the 24-105 anyway. But just grabbed the camera and this lens was on it. Not intentional to shoot with it this morning.

Just curious, what are you using for your raw conversion? I'm not using anything fancy, just Silkypix, and not really run across anything that's not correctable. That I can notice anyway. I mainly shoot wide open too, at car and bike shows mostly. Landscape I generally stop right down anyways, so I've not really had any issues. And I pretty much use my S 14-28mm for that. And the worst lens in the system that shouldn't be allowed to exist lol lol. I do like my S 26mm F8

Lightroom, the cheap version with backup to the cloud. Not the classic. And yes it has terrible vignette correction. +1 is already very ugly.

He he he. You want cheap? I generally just use the Panasonic only version of Silkypix, which costs the grand total of around 50 bucks US for life, when on sale. And find it pretty darned good to be honest.

Really hated SilkyPix. I also have DXO Photolab 7, but hated the rendering of my s5ii files, Fuji and Ricoh were fine. Maybe I can take another look. But I'm generally very pleased with LR. I like Capture One the best. But I hate that you have to pay for a new version just to use a new body, instead of a driver update. And it is very very expensive. Had the free version with Fuji, and then when they dumped the free Fuji version I got the full version at a reasonable price, but also much more functions. But then I got the S5ii which was not supported with the 2022 version I have, and then I should buy a new version again for full price. The problem then is, if you get a new lens which is not supported by the current version, you're screwed, and have to cough up again for a new version, or you have to get the subscription model for like triple the price of the Lightroom subscription.
