“With Jude, his mentality is incredible for his age,” Southgate told reporters, per Reuters. “To have such an impact at such a young age, to show such maturity but also humility. We’re very lucky to have him.”

Italy has two games remaining in the qualification process which will be played in November – at home to North Macedonia and away against Ukraine – knowing it needs to move into second place in Group C to qualify for next year’s tournament.

The diagrams above show the setup to align and measure your lens to get the information for calculating the focal length and field of view (FOV).

As I often say, “garbage in, garbage out”. The more accurate measurements you make, the more accurate your results will be.

The 20-year-old earned the penalty for England’s opener and set up Rashford to score the second as his excellent club performances for Real Madrid translate to the international stage – Bellingham has 10 goals and three assists in his first 10 matches for Los Blancos.

As shown above, I put some tape targets on the wall that point at the edges of the field of view and the exact center of the frame. I made sure that the distances on either side of the middle of the frame exactly matched. I also made sure that the lens was at exactly the same height as the middle wall target. Using high magnification via Live View or the viewfinder helps getting the targets more precise.

One reason you might like to measure this stuff, versus just reading the lens focal length stamped on the lens, is that manufacturers often lie about the true lens focal length. This is particularly true of long zooms, which might not be as long as claimed. It’s often the case that a lens focal length reduces drastically when focusing close (called focus breathing), and these techniques could attach real numbers to that.

My setup was on a tile floor, and I used the tile grout lines to make sure the lens axis was exactly perpendicular to the wall. You could also temporarily tape a little mirror against the wall and line up the camera until you see your reflection in the center of the camera’s field of view.

It also secured the Three Lions’ place at Euro 2024, which will be played in Germany next year, with the team sitting atop Group C with 16 points after six games.

The result enacted a modicum of revenge for England, which lost to Italy in the same stadium in the Euro 2020 final two years ago.

After the victory, England manager Gareth Southgate was keen to stress the impact Bellingham has had on the team, despite his youth.

I happen to have a fun little laser that can make extremely accurate measurements over long distances. I used this device to get my targets placed within a millimeter, and to measure the camera-to-subject distance.

“We need to grow and develop in those big match-winning moments. We played well for the majority of the game, but we need to take our chances.”

Using these techniques, you could actually find out what an un-marked lens’ focal length is. You could also verify (or debunk) manufacturer claims about the real focal length of a lens.

The nearer wall distance setup is called ‘x’. The farther wall distance setup is called ‘X’. Similarly, the distance along the wall from the frame middle to the frame edge in the nearer wall setup is called ‘y’, while the farther distance setup is called ‘Y’.

The mathematics used in the calculations involves both algebra and trigonometry. Any “scientific” calculator has the necessary features to do this math. You can always download a scientific calculator app onto your smartphone. Fear not the math.

For both setups, the angular measurement from the lens axis to the frame edge is called ‘Angle’, measured in degrees. The FOV of the lens is twice the value of ‘Angle’.

England came back to beat Italy on Tuesday to book its spot at Euro 2024 and leave the reigning champion’s hopes of qualifying hanging by a thread.

For a four-time world champion and the reigning European champion, not making it to Germany would signal another major failure.

You only need to take 6 different measurements to calculate everything! The trick is in setting up the targets to make those measurements accurate.

“I don’t think the team deserved to lose by two goals,” Spalletti – who took over as manager in September after the previous head coach, Roberto Mancini, quit – said, per Reuters.

I made all of the distance measurements relative to the lens axis and to a spot on the lens that I guessed to be near the vertex of the red arrows shown in the diagram. You don’t really need to know this location, since these techniques will actually calculate the location.

If the two-time continental champion fails to make it to Euro 2024, it will continue an unprecedented period of disappointment for the Italian men’s national team, having failed to qualify for the last two World Cups.

However, the defeat leaves Italy’s hopes of qualifying in the balance with the Azzurri on 10 points after six games, three points behind Ukraine which has 13 points after seven games.

To get all of the necessary information, you’ll need to set up some targets on a wall (I used painter’s tape) and then take distance measurements at two different camera-to-wall distances.
