I disagree, Steve ... that extra bit of speed brightens the view thru the finder on these older cameras, which is an asset, especially when photographing during the "magic hours" or in the evening. Plus, a touch of softness may be most appropriate for many photographs. And the very limited DOF offers some creative benefits as well as some challenges. The world isn't always best represented by sharp images.
I take your points, Shel. Sylwester was only asking if it would improve his ability to take "unblurred" low-light photos, but I guess the extra viewfinder brightness might be a useful aid to accurate focussing. You've tried it and I haven't. :-) I do prefer my M50/1.4 to my M50/1.7 for that reason though, and that's also only 1/3 of a stop.
