On fullframe :
- The 24mm has indeed distortion, so close portraits = definitely nose/face distortion.
Wedding photographers use it for environmental shots for people with a lot of background (wedding car, etc... with 1.4 bokeh), legs look longer shot from below, some like the distortion.
-The 35mm is a normal focal length, meant to use as a "model+environment" lens if you use it for portraits.
Also fine for example a doctor in front of his practice, a shopkeeper in front of his shop,...
It's not meant to come close & take a head/shoulders portraits, this is more a general lens, also great for storytelling city photography.
-The 50mm is made for half/body shots, most say there is some distortion if you take a head/shoulders portrait with it like the 85mm, but it's less noticeable.
This is a compromise between the 35 & 85 for people who find the 35 too wide and the 85 to narrow, often used in fashion photography to show clothes on half body shots.
-The 85mm focal length is known as distortion free, most flatering, superb for head/shouldershots.
-The 135-200mm range is perfect, from a far distance the model really pops up due to the focal length, some call it the "3D effect".
From 85mm on faces/bodies start to look normal or skinnier than wider lenses.
So you have to decide for yourself how much background you want in your primes and how much distance you have.
You can also move your feet offcourse, a lot of photographers say the 85L & 135L really shine on full body shots when you have a lot of space.
