As a new R8 owner, I'm looking for a wide angle lens for landscape and cityscape work. I have 35mm length covered on a 35-70 f4 zoom, and the results are excellent. For a wider perspective, I am considering the vario-elmar 21-35mm lens, mainly for the flexibility in focal length. I understand that this is larger than the R-elmarit primes, and a stop slower, too. At least half my shooting is on a tripod, and much of the rest in daylight. Are members happy with this lens and its handling on the R8?
