There may be a slight bend in the shaft but it is NOT EVEN CLOSE to the amount shown in those picture or especially the ones of Tiger. It is an illusion with the way a camera takes photos. They are take top to bottom so when something is move very fast the bottom part of if will be "snapped" at a different space in time.

 

The pics of Tiger were taken with a high speed video camera at thousands of frames per second.

 

The shaft bends to the right on the downswing well before impact. This bending does take place

in many tour pro swings. Just pick up a driver in your living room and do the pump drill swinging

the club from the top of your back swing downward in a fast motion and you will see the shaft

bend like this.

I'm sorry but you are wrong. I can show you pictures of helicopters with propellers that look bent due to same effect. I film in high speed every single day as well as have a pretty darn good knowledge of physics. It bend but very very minimally and not even close to the amount any of the photos posted show. How about the one I posted with no flex from Asleep's video? Btw those are from golf telecast so how do you know what speed they are shot at? It is the shutter speed that matters not the frame rate btw and you have no clue what the shutter speed was during those videos.

The shaft does bend to the right sometimes with certain players. I've been a videographer and photographer since
the 60's and I also have video using 1/10,000 shutter speed with the shaft bending to the right (from the golfers view)
on the downswing before impact. Sometimes it happens when the shaft is near the right leg and sometimes it happens
a bit beyond that point.

You're right, with stiff profile shafts, it's not much when it happens and it doesn't always happen. I've never seen it
happen AT IMPACT, always well before that point of the swing. With a Sony HDR-FX1 set at 1/10,000 shutter speed
I have captured video where this kind of bending is revealed. I have taken thousands of hours of video golf swings
over the last 30 years, from Hasselblad SLR stills to Fastec high speed cameras and everything in between.

Most pros I've seen using cameras have not been formally trained with a camera. Most only takes pics from the face on
and Down the line views also. Basically worthless views when using video to unveil what a player is doing that is keeping
him or her from achieving desired ball flight. But, that's a whole 'nother debate.

I'd like to see a photo shot at 1/10,000 with that much deflection when the club is at the right leg. Btw all the photos in question are at or around impact. With that much deflection that close to impact nobody could control the ball. Even when swinging a rope it would be straight or bent the other direction doing to the the force is always being directed down out and forward by the hands. The only way for the shaft to bend like that is for the hands to decelerate at a very rapid rate.

 

You honestly believe this isn't the camera?

 

 

What camera angles do you believe should be used to better see what a player is doing?

I don't think in terms of what "should be used." Too limiting. I must have a hundred different angles I've used capturing
golf swings with video. Think of a golfer being in a sphere and you can float around the golfer and take any angle you
wish. I've laid between a golfer's legs looking up at his grip so I could capture his hands going through impact from that
view. I've isolated every conceivable part of a players body during the swing from head to toe and also have isolated the
club at every point in the swing from angles teaching pros wouldn't even consider taking. Amazing what you can come up
with when you blow the lid off creativity. I've never seen anyone take the angles I do, except once in awhile the guys on
TV with the BizHub camera occasionally zooms in on a swing from an unusual angle.

What good does this do as it relates to the average golfer taking a golf lesson. Well, when it comes to fundamental moves
of the golf swing, it allows a student to see what's going on in a way they've never seen it before & many times that kind
of visual can be what it takes for them to break through to the kind of understanding he/she needs to start swinging in a
different manner. Areas of the swing like the transition from backswing to downswing or hand action through impact can
be better revealed from numerous close-up angles.

With top players, I've been able to uncover details of their swings that they were unaware of and no one had ever revealed
it to them before. Some of those subtle quirks can cause slight problems with a player who is trying to hit a particular ball
flight. A player may be hitting a cut shot beautifully, but when he tries to hit the draw under pressure it's not happening with
the precision of his cut shot action. All it takes is a clear view of what is really going on at the point in the swing that is causing
the problem and changes can be made quickly and the player can be hitting a gentle draw as well as his other go to shot.
It's not always easy, but I've gotten some excellent results for guys when others they went to couldn't. So often methods
fall short of solving immediate problems and I have found that hidden oddities end up being the trouble makers. Nothing
you tell a player becomes worthwhile until he has a clear picture of it and he can put it into motion like he's done it all his
life. When it comes to competing players, time is of the essence, as I'm sure you know, and getting lasting results quickly
is what it is all about. At least in my world that's the way it was when I was teaching a lot.

NO!!! This is purposely distorted. It's a spoof. It's a joke.

 

You are right about the bending being subtle. It is. There have been times when it

is easily noticeable, but, camera angles, lighting, and quality of camera all have an

effect on what ends up being captured. I'm really not disagreeing with you that much

iteachgolf, but, a shaft does flex in that direction to a slight degree at times.

"Besides being fast, most modern film cameras shutter curtains now travel horizontally, rather than vertically. This changed orientation limits our ability to see any distortion, as most fast motion is also horizontal (the effect on Lartigue's car would have been everything getting slightly wider or narrower).

What amuses me, however, is that digital cameras are bringing this type of distortion back.

A digital camera's imaging element, either a CCD or CMOS sensor, is made up of pixels that are organized into horizontal lines that are then stacked to make a picture. And the camera takes the picture by reading each pixel from left to right, line by line, from top to bottom. In the end, pixel number one in the upper left corner of the frame is sampled long before pixel five million in the lower right. Sure, the whole process is usually done fast, very fast, but it's not fast enough to keep these helicopter rotor blades from looking bent. The camera in my Clie has a particularly slow scan rate, making it easy to lean cars sideways. I took advantage of the effect for a self portrait when I wanted to blur my office in the background."

I thought this was a golf forum, not a camera shaft bending forum. and besides if it happens then it happens
