I agree with Michael that the Leica 21-35 is not really worth the asking price in terms of optical performances. For Leica R wide angle lenses, I will only consider the Leica Elmarit-R 19mm f/2,8 Ver II, and the Leica Elmarit-R 28mm f/2,0. The only zoom lens you may want to consider is the Leica WATE-M 16-80-20 lens.
The WATE is 16/18/21mm. Mine is excellent, small and light. Also expensive. You need the special 67mm filter attachment (about $99) to use with the lens with filters and it replaces the lens hood. Performs well on a stock A7 series camera but even better on my A7r V3 Kolari thin sensor modded camera. I have found that f8 in particular and smaller apertures for sharp corners. Others including Fred have indicated a midfield dip in sharpness. I know that Jim Kasson prefers the Sony 12-24mm and sold his WATE after his test comparisons. But the WATE is much smaller and lighter and easier to use filters.
Below are 2 photos of Dark Hollow Falls in Shenadoah NP, VA taken on October 19, 2015 after the park had 16" of rain a short time before the photos were taken. Water of the falls was abnormally high in October due to all of the rain.
The first image tripod mounted Sony A7r and my Leica M WATE f4 lens, 21mm, ISO 50, f8,1/3 second. Exposure corrected by +0.24 Stops. The image was cropped along the left and right to create a 16" X 20" proportion, not because of the corners not being sharp but I preferred the proportions and my first photo of these falls was taken in 1992 with my Linhof Super Technika IV with my Rodenstock 90mm f6.8 Grandagon N MC on Fujichrome Velvia 50 with these proportions.
The second image tripod mounted Sony A7r and Leica M WATE f4 lens, 18mm, ISO 50, f8, 1/3 second, full frame. Exposure corrected by +0.24 Stops.
The next 4 images are 100% crops of the second image. Focus of both images was on the yellow leaf to the left side of the large rock. But, 100% crop of the second image of the lower right is sharp into the corners but is suffering from the change of shape of the large rock in the foreground,
As to the Leica R 28mm f2.8 Elmarit V2, it is an excellent performer on the stock A7 series cameras. I can provide images if you wish. Yes the newer M 28mm lenses may perform better on an M camera but they have issues certainly with a stock A7 series camera. On a Kolari modded camera I am not sure regarding the newer Kolari modded A7 series camera. For myself, I also have Minolta CLE MC 28mm M-Rokkor lens without the white spots. But it has issues with a stock and even my Kolari modded A7r V3 until stopped down for moderate to long distance images. Optimum performance of the lens into the corners is f11 or possibly f8 (not quite as good as f11). There is concern about the lens developing white spots in high heat so not such a good idea for you in Utah. For me in eastern PA, I can and will use the Minolta due to its extreme light weight (about 5.8 oz with the B+W uv filter, Minolta bayonet hood, and caps) when the temperature is or will be below about 80 degrees F to prevent the white spots from developing.

, I wondered what lenses they had in a zoom wider than 35-70. I came across the Leica 21-35mm ROM. Not a lot of results come up about this lens, other than sale ads.
