And even if he/she used one of the super nocts, they would be stopping it down and still get appreciably decent thin DOF. Also I am not sure why any one would shoot clouds using an ND filter on a lens faster than 1.8 and that too wide open. What thin DOF advantage are we getting here? |
Those were just examples from google to show effects achieved via Nd filters. Nothing more.
About the thin DOF. I am just going to give a simple example with different lenses and different apertures or what dof you get. This is the only way i can make it clear why you can use noct lenses (btw canon used to make 50mm f0.95, so its not only leica) wide open during the day to get crazy yet CONTROLLABLE dof. And the lenses don`t need to be stopped down.
What DOF you get with different lenses at the same subject distance, shot wide open.
-Nikon 300mm f2.8G + d3 with a subject at 2.5m* (exactly minimum focusing distance) at f2.8 will give dof of 10.3mm or 1.03cm
-Nikon 200mm f2G + d3 with a subject at 2m away (just over minimum focusing distance) at f2 will give dof of 10.8mm or 1.08cm
-Nikon 70-200mm f2.8 + d3 with a subject at 2m away (around 1.3 times the minimum focusing distance) at 200mm f2.8 will give dof of 15.2mm or 1.52cm
-Nikon 135mm f2 DC + d3 with a subject at 2m away (just over double the minimum focusing distance) at f2.0 will give dof of 24.6mm or 2.46cm
-Nikon 105mm f2.8 + d3 with a subject at 2m away (nearly 7 times the minimum focusing distance) at f2.8 will give dof of 57.9mm or 5.79cm
-Nikon 85mm f1.8 + d3 with a subject at 2m away (over double the minimum focusing distance) at f1.8 will give dof of 57.4mm or 5.74cm
-Nikon 85mm f1.4 + d3 with a subject at 2m away (over double the minimum focusing distance) at f1.4 will give dof of 44.7mm or 4.47cm
-Nikon 50mm f1.8 + d3 with a subject at 2m away (over 4 times the minimum focusing distance) at f1.8 will give dof of 169mm or 16.9cm
-Nikon 50mm f1.4 + d3 with a subject at 2m away (over 4 times the minimum focusing distance) at f1.4 will give dof of 132mm or 13.2cm
-Nikon 50mm f1.2 + d3 with a subject at 2m away (exactly 4 times the minimum focusing distance) at f1.2 will give dof of 113mm or 11.3cm
-Noctilux 50mm f0.95 + d3 with a subject at 2m away (exactly double the minimum focusing distance) at f0.95 will give dof of 84.5mm or 8.45cm
-Nikon 28mm f2.8 + d3 with a subject at 2m away (exactly 8 times the minimum focusing distance) at f2.8 will give dof of 887mm or 88.7cm
-Nikon 28mm f1.4 + d3 with a subject at 2m away (exactly double the minimum focusing distance) at f1.4 will give dof of 428mm or 42.8cm
-Nikon 14-24mm f2.8 + d3 with a subject at 2m away (around 7 times the minimum focusing distance) at 24mm f2.8 will give dof of 1261mm or 126.1cm
-Nikon 14-24mm f2.8 + d3 with a subject at 2m away (around 7 times the minimum focusing distance) at 14mm f2.8 will give dof of 12600mm or 1260cm or 12.6m
Now can someone please choose a lens that can be shot wide open for portraits during bright sunlight.
I can give scenarios but the fact is, 50mm and 85mm lenses are best for shooting wide open. You get the sweet spot for dof, even at f0.95 you get enough dof to get almost complete face in focus. When you go between f1.2 to f1.4 its almost perfect dof for isolating everyone from the subject.
**Unfair treatment with inclusion of 135mm f2 DC since it lets you focus-defocus out-of-focus background. If you think 85mm is the ultimate boken machine, then you need to shoot with 135mm f2 DC, since this is the ultimate boken machine and no 85mm stands ground in front of it.
I Hope doing all these calculations was worth it and i was able to put my point forward without sounding rude.
Cheers
