Phil: I believe Paul Yi, the OP, has the 24 Elmarit, and has posted image with it here over the last couple months or so.
Adam. I use 21mm without any accessory viewfinders and it works pretty well, as I\'m quite familiar with that focal length and can guesstimate the composition. I think for 24mm, just use the 28mm lines and remember that there will be a bit more. With experience it becomes second nature. IMO, the M system isn\'t about super precise framing anyway, so I don\'t try to fight it or get upset about the inevitable framing inconsistency. For sure, once the new M starts shipping it will change that to some degree....
A fellow, whose name I didn\'t ask, and his very friendly and inquisitive Collie pup Rootbeer , pause at a lookout at Beamer Memorial Conservation Area on the Niagara Escarpment to enjoy the view over Grimsby and Lake Ontario in the distance. M9 & 50 Lux ASPH around f/2.8:
Another view from a different lookout, this time looking east along the Niagara Escarpment towards Niagara Falls (you can see the mist from the falls in the full-rez image). Also 50 Lux ASPH, beween f/5.6-8:
