The idea of researching different lenses from the last 20 years seems like a daunting task for a new photographer like me. So that's one reason why I've stuck with just shooting with native lenses. I currently own a 20mm and the 45mm. And I'm aware that adapted lenses can be much cheaper and can take great pictures. But from what I've read on here it seems like I can't change the aperture and you can't auto focus with them. But I don't understand why they seem so popular on this board? So I have to ask the question...what I am not seeing? Are only the people who had purchased the lenses before acquiring a m4/3's the only ones using these lenses? Or people on a budget? Or am I completely misinformed on them? I would just like some insight from more sophisticated photographers than myself on this!
