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.

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

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

I can confirm the 18-105 doesn't drop focus like the 18200. It isn't parfocal either, the focus shifts quite a bit when zooming (in MF mode).

On my EA50 whatever I set this switch to - the zoom travels at the same rate - It's useless.

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.

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!

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.
