Wizofoz, you can get a better estimate of the distance in a shot using AOV. I normally use the height of a player, but here I'll use the stumps height. According to Law 8 in the link below, the height of cricket stumps is 71cm (28" or 2.33').

Laws of cricket - Wikipedia, the free encyclopedia
The height of the stumps in the full-frame (i.e. not cropped, but resized) shot you posted is 55px in a 397px high frame i.e. 13.85% of frame height. The total height of the frame is thus approx. 0.71/0.1385 = 5.13m.

Exif data shows that the FL was 250mm. Using the AOV calculator

here, set to the Pentax K-7 or or K20D sensor (same physical sensor size), with a FL of 250mm, I inputted a few distances until I got one that gave me a frame height ("Vertical coverage") of 5.12m. That's 82m. (82.2m gives the exact 5.13m frame height, but the measurements are not exact enough to warrant that precision.)

Pentax K-7

FL: 250mm

Subject Distance: 82m

Vertical AOV: 3.57°

Vertical coverage: 5.12m

So you were about 80m away.

Using the link to the

formula to determine what FL is required for the close framing of a subject at a distance, (I made a mistake there, using a FF sensor height of 24mm instead of the APS-C height of 15.6mm - I've now amended the original calculations in that post) assuming a player height of 1.8m (5'11") and 15% free space at the top & bottom (a total of 30% extra height), at 80m a FL of 680mm would be required.

**80m * 0.86** (a "Frame-Fill Factor" based on a total height of 1.8m * 1.30)

** / 100 **= 0.688m = 680mm FL

So, depending on how many subjects-of-interest are in the frame and how close you want to crop, you may still end up cropping a 500mm FL shot at this distance.
