Oops...threadstarter is infected by "Poison #1"
Welcome raytoei.
The focusing viewfinder on the iiif is indeed very close to the 135mm frame line. You will get excess image on the top and the bottom which will not be in your image. Best is to get a dedicated viewfinder. There are many cheap 135mm viewfinders around and it's not actually a much sought after focal length. Alternatively, get a zoom finder that goes from 28 to 135/200mm. Then you'll not have to worry about any other lens you get for your barnack Leica.
Cheers,
Now infected by "Poison #2" too.
Wait till "Poison #3" to be in and you will be totally "cured"!:bsmilie:
