obviously 45/1.8 is a good lens.. and the gx1 with pz 14-42 is very fast when focusing..

however, without any systematic testing i experienced many times that the shutter was stuck after quick shots... it looked like the lens could not lock focus suddenly (no beep and the focus square) hence the shutter could not be pressed...

anyone experience the same... and what do u think the reason for this happened?
 
If you have focus-priority turned on, and the lens can't lock AF, the shutter won't fire. This isn't a case of the shutter being "stuck", it's the camera doing what you told it to do.

The real question here is why the camera wouldn't lock focus, and you haven't given us enough information to even guess.

Bokeh is the aesthetic quality of the blur in out-of-focus areas of an image, or the way the lens renders out-of-focus points of light. Bokeh is not the same as depth of field (DOF).
 
i was shooting in AFF mode... single shot not burst mode... just press the shutter one after one... in the same scene, i was using the PZ 14-42 and the focus was snappy... changed to 45/1.8 the focus was snappy too but after a few quick shot the shutter stuck, then i looked the lcd and found the focus was not locked.. the subject was about the same distance as those shots b4...

i was shooting at F1.8...

would it be a compatibility issue of oly lens on panny body?
 
Another question, what was the write status of the camera ?

If you have a slow SD card and were shooting RAW you might have ended up in a situation were the buffer was full and slowly writing to the SD card; In that situation the camera refuses to take pictures as it has nowhere to store them until the buffer cleared enough.

Certainly not a compatibility issue - I use the Oly 45mm all the time on my G3. And your shutter wasn't "stuck", that's a whole other hardware problem. As others have said, the camera will not take the picture if it hasn't achieved focus lock (if you have focus-priority turned on, which is the default I believe). Focus is more critical with the Oly 45 at F1.8 than it is with the kit lens, so if there were difficult focussing conditions (low light, no contrast) then the camera may not be able to achieve focus lock quite as easily.

Buffer full, too close to the subject, not enough light, or any number of other reasons why the camera could not focus...

Different lenses have different minimum focusing distances. Kit lenses tend to focus close, because the assumption is the user won't have a macro lens, and therefore it worth paying the price for close focusing 9slower focusing).

The 45 works perfectly on Panny bodies.

i was shooting the same subject at the same scene as i shot with PZ 14-42... so, lighting and subject distance are roughly the same. i didn't know why the camera suddenly could not focus with 45/1.8 after a few quick... buffer full? hmmm... would there be any msg prompting when buffer full?

i am using a LEXAR GOLD 32G card. it should be a fast card... but that i experienced quite a few time the camera was trying to write the data to the card b4 camera off... have u guy experiernced the same?

btw, what is focus priority? i set the AF to face detect by default... i thought the camera would always focus priority except in MF mode you could press shutter anytime you wish..
 
any msg prompt when buffer full? i didn't notice any when the shutter could not fire..
 
Focus priority means that if camera can't get focused, shutter will not work. When you switch focus priority OFF, you can shot without focusing ( and get out of focus shots)

I’m surprised how much Wikipedia contributes to the forum.

I'll take a guess. It's happened to me. The GX1's touch screen let's you finger point where you want the cam to focus. The camera was probably trying to AF on an area he'd picked accidentaly simply by inadvertently touching the screen and couldn't lock on.

Still, the minimum focus distance on PZ 14-42 is 20cm, and on Olympus 45mm it's 50cm, so Olympus can't focus as close as PZ can.

no msg when the focus not locked... but writing before the camera power off... it looks weird to me becuz it didn't happen with my g9... i know the raw file maybe bigger (16MP) but i used a faster LEXAR GOLD card...

have u guys experienced the same?
