Thread: AF & Shooting through the net
08-30-2006, 01:37 PM #1
Here's another photo showing the AF focus issue point. Unfortunately, it picked up the highest contrast area. AT the back of the court!! So the moral of the picture is, aiming the AF point at the legs of the players on the margin of the shorts/skirt and the skin won;t always work!!!

Here's another advantage of the 30D's AF that I picked up yesterday. If you have a high contrast area for AF behind the net, most times the AF focuses BEHIND the net, on to your subject. I know a guy who was using a 1D - he said he had to manual focus when shooting through the net because the 1D would always lock on to the net.

Some clarification. I spoke this person again, and he had used all point focussing on the 1D. When he switched to centre point focus, he found he could shoot through the net.
For those Nikon D70 users, another friend showed me her pics (printed out on 6 x 4) using a D70 and 80-200/2.8 (not the VR version). I must say they turned out pretty good and better than the high noise ones from the D70 that I've seen posted on BF.

one more example here. that's from the well known "walkout" incident!

9 different focusing points aren't really helpful. coz rather than the one in the centre. all other points are less sensitive.

I will try to focus the part of body below the net next time. Hope with my new gear

I am at a loss about the digital camera world (I have yet to venture into one) and I am a bit confused by focusing problems some of you seem to have, especially when using AF. The court has very good lighting to allow for adequate fast shuttle speeds and relatively large but appropriate apertures, to just use a setting with enough depth of field to ensure the subject is sharp but at the same time to blur or out out of focus the background. Pictures with out of focus background will be more 3-dimensional.
With today's high-tec digital cameras, why are you chaps having focusing problems? Also don't you pre-view the actual taking-aperture depth of field first before taking the shot? This should give you "what you see is what you get". Why are most of you using auto focus in badminton photography?

With more shirts with sponsor logos, i think shooting through the net will not be a problem. I think the "FEDEX" Logo is a good focusing point Anyway, whether the net interferes with AF also depends on other factors like
(1) Distance of photographer to the net
(2) Distance of the net to the player
Previously i tried to resolve this by simply focusing on the shoes though I'll certainly try through the net again if the shirt has a prominent logo. I enclose some pics where I focused on the SHOES

I think compared to manual focus, AF can bring a lot more people into photography.
Does a badminton court really have good lighting? To get a proper exposure at 1/250th-1/320th and f2.8, the ISO rating is at 800-1600. With film cameras, I don't think the situation is different. The shutter speed requirements and f stop are the same, and the ISO ratings needed for the film are still 800-1600.
Digital cameras don't come with those focussing screens that manual cameras have. Maybe it's my astigmatism but I've always had a little difficulty with focussing on a small viewfinder unless having a lot of time.
Sure, one can manually focus and predict the focus based on the players movements. This would definitely cope with the shooting throught the net problem. But as I said in a previous post, I don't have that sort of skill. I guess I could develop it but hey, that's what autofocus is there for. A purist may disagree but for me, AF means getting a higher proportion of photos in focus. All credit to the guys who do have that skill - I have a lot of respect for that skill. I have tried and found it was difficult.
Digital cameras are hi tech. Totally agree. But there are different degrees of high tech. And this is reflected in the accuracy and reliability of AF systems of which the implications were beyond me until switching to an AF DLSR. Last year, I still had a manual focus film SLR Basically, the lower end DSLR do not have as good low light AF ability as the high end ones. And badminton is usually played indoors in low light conditions. In daylight, AF is much better because of brighter conditions.

1 of BCL I think was a return of serve, the other one a regular rally. But since all from memory, i could be wrong
