|
Can't Post

I am creating a new post as I hate how all of the others get skewed and off topic. So, here's the story with regards to the focusing issues. If you're not familiar with this issue, find the previous post.
1 > If you are having focusing issues pertaining to the manual focus as I had written about in the previous post, YOU MUST LET ME KNOW ASAP. If you are having this problem, reply with information on what setup you used and/or samples. If not, post as well.
2 > Bruce and I are overnighting our cameras to Sony and they are having a tech from Japan fly in to examine these issues.
3 > I will update everyone as applicable but probably not until the middle of next week.
PLEASE ONLY POST IF YOU ARE AN OWNER OF THIS CAMERA AND HAVE RESULTS REGARDING THE ISSUE AT HAND. I NEED TO CREATE A LIST OF WHO HAS THE PROBLEM AND WHO DOES NOT AS PER SONY'S REQUEST. IF THIS DOES NOT GET DONE IT WILL NOT GET RECTIFIED.

Info regarding issue:::
Zoom in on objects that have a similar focal distance with regards to where they are....makes sense....focus on the center object at full telephoto and zoom out. The left-most area will appear blurred. Zoom back in and pan to any of these objects and they are in focus. The concept is simple and if you don't understand, think of it this way - if you film a wedding and zoom into a bride/groom in the center aisle, the zoom out, the left side will be out of focus whereas the center and right will be in focus. But, if you zoom back in, the focus is intact. That's a serious problem.
Here's a link for the non-believers or whatever....

It's 89 seconds long. Can't be more obvious. Consistent on ALL cameras. (ref:glimmer)
Dont forget you have to open your iris all the way to 1.8-2.0 when you are at telephoto 75-80%. If you get way overexposed just turn your ND filters on an if that is not enough then start raising your shutter speed. If you have plenty of light your auto controls will never reach these settings. If you hav elow light like a reception then your camera will get to these settings, which is why it is important to resolve these issues because low light footage is tough enough to deal with blurring it makes it look crappier. For any film look folk this is critical because this is where you live in your camera when generating shallow DOF (ref:bruceo)

04.23.08 Update
So Far So Good!!!!
Just spoke with Dominic (nice guy) and he told me that Sony has confirmed and been able to reproduce the problem with regards to the focusing/zoom issues parallel to the "soup clip" that I posted last week.
So, as it stands, here's what I was told in terms of time frames:
>Tomorrow - will get a call regarding when I'll get my equipment back and follow up with what is going to happen.
>Friday - Should have an answer as far as resolution to these issues.
Slowly but surely, but I'm partially happy thus far! 
For more info, check out the dvinfo.net forums - I have many more posts there about these issues.
