thanks folks, Sony guys have 28-70f3.5-5.6....
Seems I will have to wait for such a lens in RF mount, was planning on keeping just RP, I think I could still make good use, of my 750D plus kit or Sony A6000 plus kit when large aperture and high ISO are not an issue (like hiking trips in bright sunshine)
pictures taken with 750D plus kit in bright sunlight are as good in quality to what RP plus 24-105 produces, Sony 16-50 is fine at the tele end rather so so at the wide end

I did not check the RP specs, but with the R you can actually use EFS lenses with the adapter as well, no problem. I would expect with, e.g., the 750D kit lens that at a certain point in the zoom range, say 32 to 33 mm, the entire frame on FF would be covered. Maybe that is at least a temporary option . Certainly something to try out if you’d ask me.

I actually got myself a couple of Leica lenses last week, to have smaller, lighter options, but I exchanged those today - bad magenta colouring at the edges, so a definite no go. Essentially a similar problem Leica users without the special filters had, and essentially caused by the way these lenses are constructed, with rather large angles of attack for the light rays hitting the sensor.

So for now, barring the RF 35 F/1.8 Macro, I have given up and will just wait patiently for smaller / lighter lenses to

And I exchanged those two Leica lenses, which I got used, for the complete opposite , an RF 85L. Considering I used the old EF 85L for half of my shots over the weekend, I reckon it was worthwhile anyway. Also, that particular lens weighs about the same as the old one, but is just bulkier in build, is quite a bit better at large apertures (which is what I used it for anyway), and focuses faster and silently as well. Planned on getting my money back, but couldn’t resist, although I still got a handful of euros as well <ROFL>.

Kind regards, Wim
