At what point does longer focal length no longer matter? I want to take photos of things far away, like across the street.
I would do a camera test if I still owned my 70-300 Canon kit lens but I don’t. Right now the longest focal length I own is a 24-70 for my Sony.
I remember about that lens, once I got out past 150-175m, it seemed like the FOV was just cropping in more rather than actually feeling closer to the subject. But that was a cheapo kit lens that had a terrible reputation. Does that just apply to cheap lenses or do more expensive lenses have more magnification?
Is there really a significant difference between 300, 400 and 600m lenses? Of course I have no physical access to any such lenses at the moment.
Absolutely, they let you fill the subject in your frame.
Cropping images equals resolution loss and noise. You want to avoid that if you can.
