HELP-ROLLING SHUTTER RUINS MY VACATION!!

I am currently on vacation off the Virginia shore. Today I used my new SONY Z5U to tape/download via attached MCRk1 unit a FAST speedboat race.
The rolling shutter of the background wobbled like a bowl of jelly with a bending of the picture everytime the boats sped up. I was at full focal length.
Not usable and I erased same.
Wide angle is NOT so bad. We are talking REAL fast action here, not a wedding circle-style dance
So, I need someone who actually has experienced this problem with CMOS chips in a fast sports environment. I tried three different shutter settings to no avail. The XHA-1 Canon never did this during fast soccer games, car shows,cycle races or fast moving trains which are my only projects.
I need advice from specific SONY users if there is some secret workaround. I am usually good at this 'stuff' but can't figure this out.

Lou I shoot Stock car racing with Sony Pd170's and most of the time I set my shutter to automatic. Other cameras I have used were slow to respond, but the sonys keep up well. Is your camera still or are you panning with the action? When I am taping Sprint cars, very fast, if I hesitate the camera I have a blurr. What is your shutter speed? When they get into lower light some of my cameras don't do well with action shots. My JVC for instance requires a lot of light to get an accecptable picture.
Where in VA are you? I have property in SW Va. Bob....

Actually, it's not a shutter issue but a CMOS chip issue and how the chip reads fast action and flashing lights such as a DJ and a photo flash. I tried 1/250 and 1/5ooth as well as 60 for shutter speed.
The powerboats took off by the Chesapeake area and much to my dismay, the entire bakcground was wobbly.
BTW: I hate using these small notebooks to type but they are good for travel.

I have one small Sony handicam that I use for B-roll and I think it has the CMOS chips I usually don't use it for subjects passing the lens but rather coming toward it or going away from it. I have got some neat shots from it. I got a crash that happened rightin front of it 3 weeks ago. What a shot. I'll probably sell that to whacked out sports. My little Sony is a year old maybe there are some changes in the chips. Enjoy your vacation. We haven't been able to take a vacation for a few years. I work too much and my wife has 2 dogs and they cost a fortune to board. Bob...

As far as I can tell there is no answer to the rolling shutter problem other than buy another camera. I understand that is what several people have done here in the UK who do action shoots. I would not buy one of these cameras. I do not like nasty surprises, and I think it is more and more difficult to avoid as technology changes so rapidly. A good site to explore is DVinfo net before buying. I will try Google for 'rolling shutter problem'.
Sorry Alan.

Just to be clear Bob, the issue is not fast subject matter, it is fast camera movement (aka: used to follow fast action) that causes the wobbly artifacts.
You can capture a race car or a hummingbird's wing in motion with a CMOS chip cam if you are holding the cam steady.
It is when you start fast panning where you run into trouble.
If you really want to see the wobble just firehose with the cam (of course you should not be doing that anyway LOL), but it accentuates the issue.

I see what you are lalking about Tim. My CMOS camera is always still. I guess thats why I have never seen this effect. Well come to think of it I used it when I first got it for a in-car camera, but it was mounted solid. It sounds like Sony has an albatros.

Absolutely it is the panning of a fast object. Hate to see what our friends in the UK have to put up with following a soccer game.
Here is an internet .jpeg example of a race car. The background appears like putty.

Yes I see what you mean Lou. Thats bad. Has Sony addressed this problem? When my bigger Sonys are still and a fast object passes it. It doesn't do well with the lens or focus and is worse in low light. I don't know what chips they have in them but they are good in low light as long as they are panning or your subject is still as in a stand up. Bob...
