Hey all. I've got an M50 and have observed something quite strange. I've only got two lenses- the 15-45 kit and a nifty fifty. I've noticed that at full zoom, the 15-45 still has a noticeably wider field of view than my fifty. Why is this? I get that...

I want to complement my R equipment. I have the EOS R and may follow. I need sometimes more than 24mm and bokeh isn't an issue. The Samyang AF14/2.8 may be a good option. But I can't mount a filter. I photograph often in harsh conditions, e.g. constr...
