The SL and the idea that I can have the best of all three worlds: solid build quality, manageable weight, great glass, full frame and 24mp, a huge EVF and real-time exposure compensation, responsive AF when needed, ability to use analogue mechanical lenses yet still be able to focus them quickly and accurately, deliciously real colours.
Some of Leica's nicest lenses were designed for the R system, IMO. Even the older ones like I own are delightful performers with superb rendering qualities.
All of that matters little. I use mostly R lenses on the SL because they are a better ergonomic match to the SL body. M lenses are designed for a different kind of focusing system, on a body shaped differently, and have differently optimized controls: I find them a bit clumsy to use on the SL. R lenses fit beautifully and the controls suit the SL very well.
As always the selection of lenses is a very personal matter, nobody can do for you.
But to find out how R lenses feel, start with a inexpensive and easily available lens.
Why not the Summicron-R 1:2 50mm. If you like the way it works (I do, it is actually one of my favourites). Then go on buying R-lenses. E.g. the apo 3.4/180 is also very cheap compared to its price when new and often available.
Portraits:
Leica R 35 f/2 version II (with the built in hood) -- I love the bokeh of this lens and it has the classic Mandler look Arne describes above. Its corners never really sharpen up, but for portraits it doesn't matter. Cost is about $1,000.
Landscapes:
At 35mm I would go with the Leica R 35 f/2.8 version III (with the built in hood) which is a great landscape lens with very nice colours and good across the frame sharpness. It is a bargain too at about $700.
Another solid option here would be to select the R 100 f/2.8 APO Macro - which is a fabulous lens and does landscapes very well and of course gives you excellent macro as well. It is a much larger lens, however, and I prefer my landscape lenses to be small as I often walk a fair distance to my shoots. It costs about $2,000 or a bit more so still well within budget.
Street:
I don't shoot a lot of street so I may not be the best judge here, but my choices would be:
At 35mm the R 35 f/2 described above.
Macro:
The R 60mm f/2.8 Macro is a really nice lens and a great all around performer. It is super inexpensive as well at about $500. It would be great to add to any kit. You need an adapter to get to 1:1 macro, but it is cheap.
As described above, however, for top Macro performance the R 100 f/2.8 APO is a fabulous lens and well worth its price. You do need a fairly expensive (around $600) elpro converter which attaches to the front of the lens to get to 1:1 magnification. Natively it is a 1:2 macro lens.
I would then add the R 60 f/2.8 Macro. The lens isn't fast but it is great at all distances and a very solid lens. This is one of the best bargains and off set the non-bargain 35mm. The R 50 f/2 version II would also be a good choice here as well and would be similar in cost.

I've had most all of the lenses being discussed in this thread. I would offer advice learned from many years of Leica use/buying/selling:
Wide: the Leica R 28MM 2.8 Version II is a great lens and has excellent ergonomics on the SL. It's not quite as good optically as the newest M 28MM lenses (1.4 & 2.0), but it's much cheaper and appropriately sized for the SL.
Standard: Leica R 50MM 2.0 (try to find a german made copy, they aren't much more expensive and of my 4 copies the German ROM version was the best). Another good option is the 60MM 2.8 Macro, also look for a ROM version.
Tele/Portrait: Top choice would be the M 90 f/2 APO. I have had about 10 Leica 90 lenses ranging from the R AA to ancient M lenses and this lens is the best 90 hands down. Ergonomics are great on the SL as well. Next choice would be the M 135 f3.4 APO. Nice size, great performance and handling. A gem on the SL

I haven't seen - at least for the lenses that I look for - a great amount of change in the price of Leica R lenses. Granted, much of what I look at are lenses from the 1960s - 1970s instead of the APOs and the ASPH lenses, When I was in B&H, they had a 35mm Summilux going for $3,500 that the salesman admitted would most likely become a Cine lens. Perhaps the price spikes are for more exotic / high-speed lenses. I stick with the basic lenses as they're in my price range, and they really have not moved much. My 90mm Elmarit Mark-I 207xxxx was $250, and barring a hairline coating scratch (no effect on pix), is just about mint. I love it, and it gives my L-Flex Std Mk2 better balance than the 50 'Cron Mk1 does.
That being said, seeing cameras and lenses recover in price is nice as well.. I don't care if my Leicaflexes and lenses are stuck in "collectible prison" while other similary maligned Leicas such as the M5 enjoy a sort of collectors renaissance. I'm not entirely happy though that lenses are being repurposed for Sony FF and even the SL (although that has a converter if I recall). The FF Sony and the SL have the benefits of upwards of 50 years of advancements compared to the R-line (depending on where in the R-line one's lens is from), and for those of us who want to shoot R glass on our R-class cameras, it just makes it that much harder since the only 3rd Party i can think of that made R-mount glass was Angenieux (which is $$$) out the yin-yang. I'm trying to save up for a R9 and even if i get a basic ROM lens, I don't want outside company users further exacerbating the scarcity of the later R-lenses by appropriating them to non-native uses. That just makes it harder for those of us who want to keep everything "Leica" to be able to within reasonable budget constraints
https://www.l-camera-forum.com/topic/275905-r-lens-prices/Having used all the 35's, I still find the original Summicron my favorite, and I found the second generation 35 Elmarit the sharpest. I really like the second generation 135 Elmarit, the 24 Elmarit - a Minolta design with Leica spec glass, the 21 Super Angulon isn't to shabby, the 60 Macro Elmarit, either of the 100 macro's but of course the Apo is the better. The second generation 19 Elmarit is very, very nice, compact, solid and somewhat heavy. though I put a lot of film in front of the first 19mm. The 400 6.8 Telyt, and I found the 560 5.6 Televit better for me than the 560 6.8 Telyt.
I didn't find the 21-35 Zoom construction to be that satisfactory but optically it was acceptable, I really liked the early 45-90 Angenieux - it wasn't the sharpest in the Leica sense, but it has a very nice 'look'. I should mention that there are schools of thought on the earlier 'Mandler designs' and truthfully, if I didn't need the capability for bigger enlargements, I generally prefer the 'patina' or 'pastels' of the early lenses for my style of imagery.
Macro-Elmarit-R 60mm f/2.8 (great all rounder)
Summilux-R 80mm f/1.4 may add to your portrait options.
Apo-Macro-Elmarit-R 100mm f/2.8 + Elpro (great macro and general purpose)
Apo-Telyt-R 180mm f/3.4 (excellent value for the money)
Apo-Elmarit-R 180mm f/2.8 (excellent but heavier and more expensive)
Apo-Telyt-R 280mm f/4 (wonderful if heavy)
Vario-Elmarit-R 28-90mm f/2.8-4.5 ASPH (a really useful general purpose zoom)
The 2.8/90 Elmarit is one of the best pre-aspherical lenses Leica ever build. Ideal for Portraits. Sharp in the center wide open, with a very pleasing bokeh and wonderful colors. Stopped down one stop it is absolutely sharp in the complete field. With an Elpro you can take detailed Macrophtos. It is small, light and cheap. You can not get more Leica for your money
In all honesty, I believe that the following R lenses will become really scarce over the next few months:
19 Elmarit - 2nd Version - Already Scarce
28 Elmarit - 2nd Version - Already Scarce
35 Summilux - Already Scarce
50 Summilux - Current & Last Version - Already Scarce
80 Summilux - Already Scarce
100 Apo Macro - will become scarce
180 Apo Elmarit - Already Scarce
280 Apo Telyt - Already Scarce
21-35 Vario Elmar - will become scarce
28-90 Vario Elmar - will become scarce
80-200 f4 Vario Elmar - Already scarce
70-180 Apo Elmarit - more available due to high prices and size
105-280- Vario Elmar - Already Scarce
60 Macro Elmarit - Reasonable Availability in the near term
My favourites?
The Summilux 50 is great (but I even prefer the Summicron 50).
The Macro-Elmarit-R 2.8/60 is amazing, as is the APO-Macro-Elmarit-R 2.8/100.
The APO-Telyt-R 3.4/180 is probably the best 180-R (and still not too heavy to lug around). I own the Elmar 180 which is absolutey good enough for me and really compact.
The APO-Telyt-R 4/280 just blew me away with its IQ (adapted to a 5D MkII).
The Vario-Elmarit-R 2.8-4.5/28-90mm Asph. is probably the best R-zoom, but pretty big and heavy.
And the 2.8/70-180 is perhaps the best tele-zoom lens ever!
I have seen images shot with the Elmarit 2.8/15...

!
And they say the 3.5-4.0/21-35 is a very good lens, but I have never used it.
So a set that reads like:
2.8/15
3.5-4.0/21-35
2.8-4.5/28-90
1.4/50
2.8/60 Macro
2.8/70-180
2.8/100 Macro
3.4/180
4.0/280
... would be a dream come true!!
