Can you elaborate on the "inaccurate electronic focusing"? I haven't had any issues with auto focus... maybe I am missing understanding.... JC |
Re: Zoom problem
Me neither!!
I have peaking on and the camera focuses perfectly every time .....maybe you are talking about the lens not being parafocal??? At that price no lens would be parafocal unless it has a backfocus ajustment like the JVC HM700 cameras ....If you zoom in tight and then zoom right out to wide it ain't gonna stay in focus until the AF catches up!!

Re: Zoom problem
Aha!! So that's actually doing a manual focus pull on the stock lens so it's not electronic which is where the confusion lies..!! Servo zooms seem to have very sloppy focus rings and I'm not really sure if you are also dragging some of the servo linkages when you turn it even if you switch to manual.
I find it so much easier to focus pull on the spot focus function on the LCD ...touch the screen on item 1 then touch the screen on iten two and the camera does it for you!! Chris |
Re: Zoom problem
I've noticed the jerk when changing zoom direction as well. I've tried putting my finger on it to provide some drag... wishful thinking... In the end, I will live with it, as I still think this camera and lens is a great deal... I'm coming from a camera with very little OSS, so I'm just thrilled I can get away with what I can without the tripod... and zoom. It's still a bit like magic to me.

Re: Zoom problem
Totally agree, Chris. Touch screen AF was the greatest discovery on my Panasonic and will stand me in good stead with the Sony, I'm sure.
Anybody tried the focus transition feature that allows you to set a time interval? I like the idea of it, but suspect I'll just work with whatever the touch screen mode provides. |
Re: Zoom problem
Spot focus is not smooth in transition as manual refocus, it's ok if you want to quickly refocus but if you want to do it right, you do it manually. Also spot focus is not 100% accurate all the time because it's result also depend on sufficient light or how large the area is you need to refocus on. Only focus transition should be better as your start and end focus point will always be dead on but it takes more time to dial in which I usually don't have.

I noticed this problem in the first record when I just got the camera. from the first video record was disappointed with this problem that makes the lens to zoom in out. what to do? send it back to Sony for repair??? you with the same problem that you solved? help please..... |
Re: Zoom problem
I don't have the camera anymore but know that lens issue was "normal" behaviour as many users reported the problem, it does seem that not all lenses are equally bad but I"m sure Sony will say it's within a normal limit for this type of lens but it depends ofcourse how worse it is, can you post a video showing the problem you have?
|
Re: Zoom problem
is the same problem as in this video when zoom in and out
|
Re: Zoom problem
That's normal, my lens also had that same problem. It has to do with the design of the lens, you cannot compare it with a fixed lens on a videocamera that have variable and very smooth zoom speeds. I always operated the zoom manually on the ea50 which did work surprisingly well.

Re: Zoom problem
In the anouncement of the Sony SELP18105 it was said, that it wont have that zoom issue...
and it zooms faster... Can anyone confirm that? |

Re: Zoom problem
high, medium, low. is the speed of the zoom controller, the slider right next to it.
for use on cameras with no rocker zoom, like compact photo cameras |

Re: Zoom problem
Peter,
As Marlin said that switch only affect the slider switch next to it. It is not supposed to effect your rocker speed. If it does not change the slider switch speed something is wrong. But it is not there for the EA50 anyway. Steve |
Re: Zoom problem
Hi Pete
Power Zoom speed is set via the menu the HML switch as Steve says is for the manual slide switch on the lens .... You will find the Power Zoom settings in the menu options and they do work but remember that the power zoom rocker itself is progressive! Chris |
Re: Zoom problem
The zoom problem does seem to be luck of the draw. This tread caused me to test mine. I don't have the problem. It may be there to a small extent, but it does NOT look like the clip posted above.

Re: Zoom problem
Hi Steve
I have also never had the issue on either of my cameras using the stock lens! Then again I rarely zoom while filming I think it's more noticeable on a fast zoom (on H) as the power zoom engages so some lens might have a bit of play in the gearing network? If I do zoom it's really, really slow so that's probably why I never see it ...apart from a very rare zoom while filming I only use the zoom for framing so I would see the issue. If it does happen then a simple workaround would be to zoom first and film once you have framed or simply zoom slowly. The rocker is progressive so a light touch on the switch starts the zoom very slowly and then you can speed up once the "slack bit" is past. Chris |
Re: Zoom problem
today sent me a new lens but the problem remains and the new lens
|
Re: Zoom problem
Like I said, it's not a problem but more a design limitation, many users, including me had reported this "issue" on the stocklens but it appears to just be like that.
