Focussing is a problem though, the viewfinder is not a patch on the R8. I can not do my Telyt lenses justice using it. I actually got rid of a Sigma super wide zoom, which perhaps seemed acceptable on film because I used it rarely, because of disappointing results. The Canon replacement is markedly better.
