Can anybody help me understand this:
Using my 28 and 50mm primes to shoot my car, I can't get blur/bokeh/shallow DOF in the background. Looking at the focus distance on the ring, in order for me to get my entire car in the frame and get good focus, I have to set both at 15ft and 20ft respectively which also turns out to be their max focus distance. So, I'm basically at infinity focus and I won't be able to get any blur/bokeh/whatever.
That is correct right?
If that is right, then why can I get blur/bokeh/shallow DOF using my 85mm prime at about 16ft on the focus distance ring? Granted the max focus distance on the 85 is at 33ft so it can go pretty far.
Could this be the crop factor taking into effect on my 28 and 50mm primes?
Accounting for the crop they'd be at 42 and 75mm focal length. Since I'm having to position myself 1.5x farther out than I'm supposed to, could that explain why I'm hitting max focus distance on those lenses?
I've actually been trying to figure this out the last couple of days ever since I got my 28mm lol. I was hoping I can get delicious bokeh on the 28mm without having to stand
soooooooo far away but it doesn't work lol.
