Which portrait lens between 50mm – 135mm is ultimately recommended if you just want to have just one?
This article is about the focal length and which lenses are best suited for the specific needs of portraiture.
A photo artist also gets a 14mm lens toward impressive portraits. I am talking here, but about 80-90% of portrait photography, not about the fact that you could include in an extended portrait term also wide angle and super telephoto…
True to my motto, that given the recent 24-50 megapixel sensors only the best lenses good enough are, I have recently met a longstanding dream for the ultimate portrait lens. It was the … .- STOP: I would like to first give anything away. This one must then be the truly best in class.
Thus, this article is first of all a matter of making the ‘best’ focal length (in full-range 50mm-135mm) for the majority of portrait photography locate; followed by other important criteria such as luminous intensity, color reproduction, macro yes or no etc ..
The best focal length – 50 – 75 – 85mm – 100mm / 105mm – 135mm?
A. After the number of people
A1. Portrait: A single person is shown. This is the most common type of portrait.
A2. Double Portrait: In a double portrait two people are represented in an image.
A3. Group Portrait / Family Portrait etc. – is left out, since in principle a different focal length makes sense given the need for greater depth of field for full format, namely 50mm or 35mm)
B. After Neck
B1. Preparation standing or sitting. As sculpture and statue (still image) or statuette called.
B2. Elbow: with involvement of the knees, standing or sitting.
B3. Waist to the crotch
B4. Half-length: Waist to waist, including the angled arms with his hands.
B5. Brisket: head with a large part of the upper body, shoulders and arm portions.
B6. Shoulder or bust: The shoulder lugs are included and the portrait completed at armpit.
B7. Headshot: representation with the neck (neck portion), without any part of the hull.
Minimum Focus + minimum distance = maximum exemption Potential
Example Headshot (30cm)
50mm: Distance: 0,51m (Focus at Bl. 1.4: 0.8 cm)
75mm: Distance: 0,77m (Focus at Bl. 1.4: 0.81 cm)
85mm: Distance: 0,87m (Focus at Bl. 1.4: 0.8 cm at Bl. 1.2: 0.67)
100mm: distance: 1,03m (Focus at Bl 2.0. 1.15 cm)
105mm: distance: 1,08m (Focus at Bl 2.5. 1.44 cm)
135mm: distance: 1.38 m (depth of field at Bl 2.8. 1.6 cm at 2.0 Bl. 1,13cm)
Example Headshot (35cm)
50mm: Distance: 0,59m (Focus at Bl. 1.4: 1.08 cm)
75mm: Distance: 0,89m (Focus at Bl. 1.4: 1.09 cm)
85mm: Distance: 1.00m (depth of field at Bl. 1.4: 1.07 cm at Bl. 1.2: 0.9 cm)
100mm: distance: 1,18m (Focus at Bl 2.0. 1.53 cm)
105mm: distance: 1,24m (Focus at Bl 2.5. 1.93 cm)
135mm: distance: 1,59m (Focus at Bl 2.8. 2.15 cm at 2.0 Bl. 1,52cm)
Example shoulder piece (50cm)
50mm: Distance: 0,82m (Focus at Bl. 1.4: 1.08 cm)
75mm: Distance: 1,23m (Focus at Bl. 1.4: 1.08 cm)
85mm: distance: 1.40 m (depth of field at Bl. 1.4: 1.08 cm)
100mm: distance: 1.64 (Focus at Bl. 1.4: 1.08 cm)
105mm: distance: 1.73m (depth of field at Bl. 1.4: 1.08 cm)
135mm: distance: 2,22m (Focus at Bl. 1.4: 1.08 cm)
For half-length: (80cm)
50mm: Distance: 1,28m
75mm: distance: 1.93
85mm: distance: 2.18
100mm: distance: 2.57
105mm: distance: 2.70
135mm: distance: 3.47
Thus the 85mm focal length meets the standard requirements for the ‘right distance’ (90 cm to 3 m) in solving the objects in the size of 30cm (Headshot) to about 100cm.
