As the novelist Patrick O'Brian has one of his wisest characters say, unless you advise someone who is asking for advice to do exactly what they always wanted to do in the first place, your advice will not only be ignored but will also often be resented.
I think you should get the Sony 28-70 f/2 GM and the Sony 100-400 f/4.5-5.6 GM.

p.3 #3Replace Loxia 25/2.4, CV 50/2 and CV 110/2.5 APO with Sony 28-70/2 GM?
Update: After finding out I can get a new Sony 28-70/2 GM for less than Germany's used market prices (big thanks to @Stefan Official for your Panamoz 'review'!) it took me several days to accept that I'd have to buy this lens.
I have done plenty of comparisons and can confirm this is an outstanding zoom lens!
It's optically better than the Zeiss Loxia 25/2.4, Sigma 35/1.2 and can almost match the CV 50/2 APO. Optical and mechanical vignetting are actually lower than on the CV 50/2, light transmission is higher.
Despite reading everything I could, I only found out after trying it myself that close-up performance is surprisingly weak.
With the Canon 500D (+2), VC 40/1.2, 50/2 APO and 75/1.5 perform better.
If anyone is interested, I can give the magnification numbers for several combinations.

Sure. Almost all of my gear is from Panamoz, and I’ve never had any issues. The support is always quick and feels genuinely personal, without the usual copy-paste responses.
Especially with high-end lenses or camera bodies, you can save a significant amount of money there. For cheaper lenses, though, it’s usually not really worth it.
I mainly use this lens for its image quality. The colors and overall rendering are outstanding, and in some cases I even prefer it over prime lenses.
I can’t really comment on close-up performance, as I rarely shoot in that range. If I do, I typically use the Sony 90mm macro lens.
Maybe you could add something specifically about its performance at close distances or at the minimum focusing distance. That would likely be very helpful for others who want to use it in that way.

The 28–70 has incredible rendering, genuinely better than a lot of primes. Honestly, if it weren’t a three‑thousand‑dollar lens and if I didn’t already have a dozen Sony lenses plus two other systems, I’d buy it in a heartbeat. The only real drawback is the size.
I’m glad you’re enjoying the lens. At the end of the day, it really comes down to what you like, not what this group thinks.

I've done a direct comparison with the CV 50/2 APO. At distances <1m, the CV 50/2 APO just retains resolution better, despite both lenses featuring FLE. The Sony gehts kind of mushy towards the corners and field curvature becomes noticeable.
Add a close-up diopter and the Sony exhibits visible CA.
However, I'm using it on Nikon, so sensor stack differences might play a role.

p.3 #7Replace Loxia 25/2.4, CV 50/2 and CV 110/2.5 APO with Sony 28-70/2 GM?
Update: I got both the 28-70 and 100-400 and used them on my last vacation.
And I'm very happy with that choice. Apart from an annoying adapter bug that leads to the lens totally losing focus that can only be restroed by restarting the camera, everything worked and works beautifully.
Before going on vacation, I did some extensive measurebating to compare it against my other lenses.
The Loxia 25/2.4 doesn't stand a chance. It is a pretty lens that is fun to use but the only thing it does better is sunstars. I haven't yet but will sell it soon.
The Voigtländer 50/2 APO stood its ground. Resolution-wise, it's stronger. But the Sony 28-70 has less vignetting, surprisingly higher contrast and less DOF at f/2, and not much more astigmatism.
There wasn't a moment when I missed the CV 50/2 while on vacation. I haven't sold it yet and I don't really want to but there is little reason to keep it.
The Voigtländer 110/2.5 can't be beat as a macro lens. That said, the Nikon 100-400 performs much better with the Canon 500D (+2 diopter achromat) than I expected. Even at 400mm and at MFD (1:1.1, effective FL 198mm), it's hard to distinguish it from the CV 110/2.5 when set to f/11. At shorter FLs or set to infinity it only gets better. All of this while offering AF, which is gold for hand-held macro.
Never would I have expected to enjoy a zoom lens that much. I thought I'd never use it below 300mm but I was very wrong. I didn't test it against the Nikon 300/4 PF VR and I don't plan to. It's that good!
I'm trying to sell the Nikon 300/4 right now but am not sure what to do with the CV 110/2.5.
