This is a close range scene, straddling the creek amidst the boulders, a bit tricky to avoid slipping and bashing myself or the camera. But the Really Right Stuff TVC-24L with its solid and long legs makes a fine companion for such uneven areas.
Here the main point of interest is overall visual impact (contrast and sharpness), along with consistency of depth of field gains and control of all aberration. That is, for strong gains in depth of field with stopping down, those optical strengths being critical for a deep 3D scene like this. See the various ways in which depth of field can be delayed in MSI.
We’d like to se:
- A crisp high contrast image free of veiling haze from longitudinal chromatic aberration or spherical aberration.
- A freedom from smearing, double images and similar unpleasantries in the peripheral areas.
- A rapid improvement in depth of field with stopping down, and without any focus shift, e.g., a a tight point spread function so that real depth of field is quickly gained (vs theoretical).
