What are the typical defects encounter on PMW-EX1. at DVinfo.net

Since you get your PMW-EX1 what are the typical defects found on this unit :
Ex : Battery Drain , Focus , Image Stabilisation .... ect.

Instead of info all over the place i am thinking of starting a info center thread here.

Those were pretty much issues only with the initial batch(es) of cameras shipped. I am not aware of any endemic issues with current production models other than the IR related Black/Red problem.

All my issues with my unit purchase 12 months ago were resolved with firmware updates.

I don't think there are defects (as such) for new purchasers. As with any prof level camera there are things you check out rather than assuming it is spot-on out of the box.

Just wondering if this an only on my camera issue, or the way it is. Love the peaking feature, however when I try and tweak the knob I go from nothing to flooded in blue. There does not seem to be a gentle gradated situation and, given the depth of field with the stock lens, even with max nd and 1.9 I'm in a sea of blue most of the time.

You can set the peaking to low, medium or high.
As for peaking going from nothing to everywhere, it would do, your subject is either in focus or it isn't.
The only time i see peaking move is when i'm pulling focus, for example when zoomed in close on say a wall length ways, adjusting the focus along the wall takes the peaking along the wall.

A number of people including me (on an EX3) have had problems with slow zoom speeds.

Check your camera for this problem in the store or as soon as you receive it.

It should be smooth starting and stopping. Set the slow handle zoom speed to 1 (slowest in menu) and make sure it actually moves at even slow speed.

When problem first appears it is quite subtle and then it gets worse. It sort of stutters when you attempt a slow zoom start or stop. It is easy to think it is a case of to much coffee.

My lens was replaced by Sony. Some people got new EX1's I believe.

I've tried the zoom speed at 1 test with old and new EX1 and both stutter. Are you saying you can perform a constant speed zoom without stuttering at this speed? If you can I guess I'm sending the camera for service.

I just went and tried my lens on 1 it stutters a little zooming out and is really smooth zooming in.

On 3 it is perfect both ways, I had one unrepeated stutter on 2. When I got my new lens from Sony it was smooth on 1, about 8 months ago.

So I guess these lenses are prone to this problem. I would definitely make sure it is right when new, and keep an eye on it as warranty nears expiration.

Manual riding of the zoom seems very smooth still on my EX3 still.

When I sent my lens back it was stuttering all the way up to 13. It would not even move on settings less than 10. And it was impossible to do a subtle slow zoom.

Another test is to do a/b scene preset to smooth transition and fairly long time and watch to make sure it zooms smoothly when executing.

I know zooming is not cool, and I don't use zooms much, dolly mows or jibs are much nicer.

But I do them sometimes, especially on an interview when a director signals a slow zoom in. And then they have to be perfect or it is really embarrassing.

And a lens should be able to accomplish this.

That's a great tip. I'm gonna try it out before heading for service. But I would call what you get at Zoom speed 1 a defect in answer to Daniel who started the thread.

Since I don't use the LCD with characters turned off too much I discovered recently I have vignetting, this is after Sony did the firmware upgrade and checked the camera so that's my main reason for sending to service. Using the century WA converter and fisheye exaggerates this vignetting to truyl unacceptable proportions.
