I’ve been trying to work this out but I can’t quite.
85mm f1.4 looks great
70-200 f2.8 @200mm looks great too (better?)
If you crop 85mm to 200mm you would get 200mm f3.3 equiv. So the 70-200 is actually better.
Ok so 105mm f1.4 exists… That’s 200mm f2.66 equiv. 135mm f1.8 is the exact same equiv. But you have to crop (not ideal).
Is there anything better still?
Does subject distance matter? Maybe with a 50mm f1.2 but with you physically closer depth of field would be more shallow? Probably not.
I don’t care about having the whole car in focus, I just want critical focus on one part and a super dramatic look.
If you were looking for a single-frame solution, for full frame cameras, 200mm f2 exists and is relatively easily available, and at some point Canon and Nikon experimented with 200 F1.8 and 300 f2, which are next to impossible to get your hands on.
