New U8 Soccer Action
Lens: DA 55-300/F4-5.8 Camera: K20D Photo Location: Sunnybank Saints playing fields Shutter Speed: 1/750s 
Posted By: dosdan, 06-27-2010, 03:17 AM

26 Jun 2010. Pentax K20 + DA 55-300/F4-5.8. Shot in TAv mode with 1/800s and aperture set to F4. Since this is not a constant aperture lens, the F-number increased with large FLs. By mistake, I left the exposure metering set to single centre-point after some testing and so the match was shot this way. So I won't bother showing the ISO, because it is rather meaningless - most of the shot's EVs had to be adjusted in PP. It was overcast, so hardly any shadows.

1. I like soccer "dance" shots. Here's one. F5.6, 260mm FL.




2. Not sure how my son got himself into this stance. It looks like he's leaped in. He likes to do that. He tells me he didn't fall over after this. F4.5, 190mm FL.




3. Sometimes the looks on the defenders are more interesting than the attackers. F5, 135mm FL.




Here's a sliding intercept save sequence. All photos are at F5, 150mm FL.

4. The first shot has the two attackers OOF (there's not much DOF for group shots at F5 and 22m subject distance), but I want to show it because it portrays a situation that no goalie wants to see: two attackers getting ready to set up a shot and no team members nearby. Also the over-exposure of the fluro bibs on the outside of the frame, caused by centre-point AE, was too much to be corrected in PP.



5. I think the attacking players may have moved a bit further forward from the last shot. Also the focus point may have moved to the attacking player from this shot onwards. There an extra 0.4m of DOF behind the focus point compared to in front.

Online Depth of Field Calculator - Pentax K20, F5, 150 MM FL, 22M distance.
In front of subject 1.96 m
Behind subject 2.39 m

I computed the distance by taking my son's height with legs spread like the goalie = 1.3m.
The goalie's height in a 3104px high frame in the original is 1786px = 57% frame height. I therefore assumed that the total frame height at the distance of the goalie was 1.3m/0.57 = 2.3m.

I then used the AOV calculator at Angle of View Calculator to find which distance gave a 2.3m height. That was 22m.

Pentax K20D
FL: 150mm
Subject Distance: 22m
Vertical AOV: 6 degrees
Vertical coverage: 2.3m




6. Our team member, Debenjamin, races in and throws himself down just as the the opposing player goes to kick.



7. He continues to slide - note his foot position compared to the previous shot - and disrupts his opponents kick.

You've got some good shots there, dosdan. Looks like your son has a few battle scars he can be proud of in later life

I like the first shot the best, although the noise is quite noticeable. Did it end in tears? They both look very committed to the ball.

Tell the goalie to keep his eye on the ball, not the camera.

Nice work Dan

Thanks for the comments. They're not battle scars. He's had eczema and that caused him to scratch himself. He's on the mend. They were a lot worse 4-6 weeks ago. I hope he never get the "battle scars" that I got riding motorbikes. I was a maniac on the road - it's lucky I didn't cripple myself... or worse.

Great shots. Love the intensity you caught on their faces. Overcast weather is what we get here more than we want so shooting in those conditions can be challenging, keeping shutter speed up and ISO relatively low.

Nice pictures, how often did you use the range beyond 150 mm?

Here's a FL frequency distribution analysis of 13 matches this year. The count is not the number of shots I took, but the number of shots I kept after PP. The list is not in chronological order.

Count227 142 338127 82 111 90 98 146 44 74 80 106
>100mm 44% 32% 34% 33% 57% 79% 82% 79% 81% 45% 51% 56% 62%
>150mm 17% 13% 16% 11% 23% 37% 41% 50% 41% 20% 28% 28% 35%
>200mm 7% 7% 7% 2% 10% 18% 19% 30% 25% 2% 14% 5% 23%


BTW, the distribution bins (discrete FLs as reported in EXIF) for the DA 55-300/F4-F5.8 lens are:

55
62.5
70
77.5
87.5
97.5
107.5
120
135
150
170
190
210
230
260
300


Point 1. These matches are played on small fields, probably less than 1/2 the length of standard soccer fields. On full-sized fields high FLs would be much more common.

Point 2. You have to choose between loose & tight framing. This will affect what FL you use.

Loose framing:
Requires more cropping - less resolution in final shots;
better chance of capturing ball in flight;
better chance of framing both kicker & ball approaching/entering goal posts;
better chance of seeing a incident develop from an intercepting player that would be out of frame if using tight framing - I track the action on a tripod so I'm usually looking through the viewfinder, not outside it.

Tight framing - better resolution.

Thanks (that is more detailed than I could expect / ask for).
- My daughters are just 2 and almost 4 years old, so a big field will take some time or if I buy a 50-135/150 mm lens then they just should play volleybal iso soccer.

Best regards,

Joep
