Starting a Olympus C750UZ thread - on usage

[Davey]

Now its a clearer picture... been wondering how you guys manipulate the manual focus... when all the while its just acts like a lock... ;p

aggaration for the manual focus is real tough... even though lcd appear sharp... you might not get the sharpness when transfered to pc... so sometimes quite frustrating...!

Me too... miss the focusing ring.....! :bsmilie:

Alternatively, if you don't often use the AEL function, you can reprogram this button to become FOCUS LOCK. Very useful for locking focus on your subject while you recompose your picture. (i.e. don't have to keep your shutter button depressed)

Another reason why focus lock is good (for me at least) is because the exposure is NOT LOCKED when you recompose your picture. If you recompose the normal way (i.e. with the shutter button held down), the exposure is locked and you may end up with an over or under exposed picture!

hmm...this seems like a good method too...! :thumbsup:
If the focusing can remain in focus while you can recompose or wait for the event to happen, it really saves a lot of trouble...!


Will give it a try and comment later...
Thanks Davey...

Davey bro...

tried your method already... doesn't seems to work for me leh... Do we have to keep on pressing on the "AEL" button so the the focus lock is always on??

Cause once i let it go... when i re-press shutter again... it will focus again...

in this way... its just like half triggering the shutter just that the button to press now is different...

please correct me if im wrong...

After reading your post, I switch the custom botton to AF lock to test on the method.

To obtain focus lock using the custom button, you have to set the continuous AF mode to OFF.

The focus will be unlock once you take the shot.
To permenantly lock the focus, you have to press the AF lock for more than a second.

During the test, I encountered a strange problem. Tried to focus lock with the AF-lock button while pointing to a subject within 500mm, the camera jammed!! I have to remove the batteries. Did this happen to anyone else?

May be I'll stick to the previous method to lock the focus, which I think the camera responsed faster too.

Raymond bro...

think previously i have done it all wrong thats y...
Yes... the fulltime AF should be off... if not it will keep on focusing and the AF cannot be lock...

i read through the manuals on the usage of AF lock and AF memory... its quite easy and effective for me...works well for me without jamming the camera...

Just point the camera at the subject with good contrast and lightings... lock the focus permanently (using AF memory), and recompose the shot...! lwhen you are done just trigger the shutter button!

I don't understand what you mean by 500mm... i thought the cam can only go max of 380mm??

Hi Bro,

Glad that you were able to figure it out!

my 750 jammed before while i was playing with the menu buttons and playback. yes i had to remove the batteries to shut down the camera.

think it caused damage to my xD card too, cos the card failed and i had to send it back to Olympus service centre.

pls help to clarify my doubt. thks.
i have attach a adaptor with an 52mm uv filter on it. when not in use, do i have to remove the adaptor n filter? secondly do i have to remove the batteries from the camera. advise.
fyi...my camera is stored in the electronic dry cabinet.

won't the settings be lost if u removed the batteries for long hours?

 

[thheng71]

well... setting can be set back easily. if u are not able to memorize ur setting, record it down on a small notebook. carry around with u together with ur cam. ;p my concern is more on the batteries leakage that might occur. would like to know what is the normal/usual practice for digitial camera storage. thks.

I keep my adapter and 52mm filter on all the time, even in the dry box, but with the 52mm cap on. As long as it is properly screwed on, i.e. no dust going into the actual lens, I think its fine.

As for keeping the batteries, there have been threads talking abt this before, generally sentiment is if you use the camera regularly (once a week), its fine to keep the batteries in, but for long periods of inactivity, better to take out.

5 cents....

 

[thheng71]

THks for ur advise. :thumbsup: :thumbsup:
I'm not a frequent user therefore I should remove batteries during storage. Re-setting the camera is not difficult after playing it for quite some times.

:cheers:

Hi, anyone knows how to set the exposure, focus and white balance while in Panaromic mode?

Manual says 'Focus, exposure and white balance are set by the first picture. Do not select an extremely bright subject (such as the sun) for the first picture'.

I'm assuming, therefore, that all these settings are set automatically by the camera? Is that correct? or can we actually set them... been frustrated so far by having nice landscapes stretching out before me, but a Panaromic feature that can't capture it. :cry:

Not too sure about the panaromic function, as my xd card is "Fuji" and not Olympus brand. I use other softwares like "Photo element" to do the stitching. I switch the camera to manual control and lock all the settings before taking the series of shots for the purpose. If the scene involved high contrast lighting condition, try using multi-metering for the exposure setting.

One thing of removing the battery from the camera for extended period is that one tends to forget to set the date to the current one, which ended up with the subsequent shots being of wrong date. It happen to me sometimes.

guess that's one way to do it... I'm using the olympus xd card, so can use the 'out-of-box' panaromic function that has the 2 rectangle strips to help with the overlapping for stitching... but as mentioned, manual controls limited.

ya...ya!! i have tat problem oso. :kok: :bsmilie: I think we have to paste a label sticker on cam to remind us to set the clock(date & time) each time we place back the batteries. haha!!

hi,
has any1 ever encounter shadow spot at the bottom line of ur photo?

[/IMG]

[/IMG]

pls advise why is it so. thks.

 

[Raymondb]

Problably its the shadow of your adaptor tube, cause you are too near to the subject.
May be could remove the tube first, or back away further from the subject.

Raymond

 

[thheng71]

thks for ur advise.
not all photos taken in wide zoom has such problem. some are pretty good. therefore i do not know the problem arise from the cam / the setting. ;(
fyi... i using 'A' mode trying at different f/stop with some exposure adjusting & flash on.

thks Raymondb.
I have try taken with & w/o adapter. ya u are rite! is the adapter tat causing the probm.
