R4M/A pix online

As I learned that in german, I had to look it up in wikipedia.

b is the base lenght, a is the distance and A is the angle which we measure when we focus the lens.

As you can see the angle A would be closer to 90° with a shorter base length or with a larger distance. So to measure large distances acuratly the base length must be longer. With a diminishing viewfinder, i.E. fractions of 1 magnification, you measure A with less acuracy, it's probably best compared to measuring a distance with a caliper (lager magnification) or with a yardstick (low magnification).

I really don't think we'll be seeing a blgger base length with the current Leica-CL-finder-grafted-onto-a-slr-body franken-camera bessa. Not without doing something radical like actually designing the camera from the get-go as a proper rangefinder. But then that's the new Zeiss.
That would be like volkswagen making an expensive deluxe luxury car to compete against the Audi A8.. when they own Audi.

And yet ... VW did with the Phaeton...

Here's hoping the Voigtlander improves the baselength! If VW can do it so can you! 😀
 
You cannot have all in one camera. If you need maximum focus accuracy buy a R3 (M or A). The R4 is for wideangles. Probably not best suited for the 35/1.2

But with the pictures, I wonder how far the 35/1.2, or any other big lens with hood will shade the 0.52x finder....

that pic looks 'scrunched' to me.

Common product photography technique to get parallel verticals. View camera technique, Camera and lens parallel with subject, camera back shifted (up or down) to place subject in frame. This causes the "scrunched" effect you see, but there is no "keystoning" of verticals.

Same technique can be used in Photoshop with scans or digital files, if one doesn't have a view camera with movements.
 
Since many wideangle lenses are "guess focused" for speed in shooting, due to their enormous depth-of-field, the main advantage of these cameras is having a built-in viewfinder, parallex corrected for shooting with these wide-angles. The focusing RFDR is just an added perk. I wouldn't be too concerned with focusing accuracy unless you plan to also use long lenses with auxiliary finders.
 
WOW! what a fanstastic camera! I just read about it! I love it! I mean you can 21mm rangefind it one! but more important you can see and compose 28mm or 25mm! just like 35mm! Added to my and only shoping list for christmass 🙂
WOW WOW WOW! I am very happy! what an excellent camera! when it will be out?
This will be a perfect match for 28mm ASPH!

Yes I wonder about this too, I think your concern is legitimate. I'm very interested in this camera for a Leica 24mm/f2.8 lens and my M-Hexanon 28. Both of those lenses have fairly wide diameters and I too am concerned about them occluding the VF.

In response to another poster above, I'm thinking about maybe selling my backup M6TTL (in the shop at the moment) in part to buy this camera. I'm not using the M6TTL any more but I would use the R4A. I need to work more with my 24mm and it's viewfinder before I plunk down a deposit.
