I've just noticed a very odd behaviour with the Panasonic HX-WA10EB-K which I hadn't picked up on until now. I've written to Panasonic about it an will post the reply when it appears, here is a summary of what I wrote.
"Hi, I recently bought an HX-WA10 which I had to return because of an image fault, I'm now using a replacement unit. I've noticed a very odd behaviour which is either a technical fault or a design fault. I have the still settings to record images in 12M 4608x2592 [16:9] format.
If I look at a subject prior to taking a picture and then zoom in to frame the subject all seems to be well, until I press the button to take the photo. When I do this the image is instantly partially unzoomed and the recorded image is a much larger field and consequently the area that I had zoomed in on (the part I'm interested in) is recorded far smaller on the image.
I just don't see what the point of being able to zoom is if the viewed image is not the same as the one captured. The image does not zoom out to it's fullest extent but given that an image will have been zoomed to exclude unwanted material it is crazy that the camera then zooms out and includes it! I have tried a number of image settings with the same result. I look forward to hearing from you."
I also found this on a forum when I was researching the issue so it doesn't seem to be just me:
"We bought two - one for work and one for pleasure. Both of them don't allow the zoom to work for photo's. you zoom in and when you push picture button it automatically zooms out....totally bug."
