I asked my neighbor if I could take a picture of him and his dog and he said yes. I was going to take a picture of them in the hallway of our building (the walls are a cream color and the ceiling is off white). I was wondering what lens should I use. Some of the lenses I have are: Pentax fa 35mm f/2, 50mm f/1.4, da 70 f/2.4, Sigma 30mm f/1.4 and the Rokinon 85mm f/1.4. I was trying not to use flash so I would not spook the dog.
look at it this way, I assume you willhave a vertical frame, so, let's do a little math.
Image size (24mm for vertical frame) = Subject size (assume 2 meters standing 1 meter kneeling) x focal length / distance.
therefore , depending on the size of the hall way, your focal length will be determined for you.
Focal length = distance X 0.024 / (image height between 1-2 meters)
If you can get 3 meters away, then about 70-75 mm kneeling, 35 mm standing.
the closer you move the shorter the lens, the further back the longer
