Someone opened a Lumix DMC-ZS50 (DMC-TZ70)?

Well, I did, to clean the sensor. And it worked very well! But when I assembled it, the focussing did not work. Opened it again, and I saw the three little screws who hold the CCD where tightened to much, so I unscrewed them a bit, and yes, focussing worked again! But on one side, the pics where not sharp any more. By regulating the little screws, now it is fine again.

What I try to say, is it possible that on the TZ100(200) the bad focus is not the lens, but the regulation of the sensor? What is your opinion?

I think you have possibly hit on the cause there, subject to further investigation and testing, it very likely is the cause. It cannot be the lens design since I and many others have excellent TZ100 & 200 lenses. If it were design they would all be bad or good and not have inconsistencies as they appear to do. So, the only sensible conclusion to draw is that it is the Quality Control (Q.C.) of the assembly process causing the problem. I think, in all honesty that fact has already been accepted

The other factor to consider is that the perception of a sharp and soft lens is of course subjective and miniscule differences can be amplified somewhat depending on one's level of pixel peeping tendencies.

The constant comparison of the TZ200 & RX100M6 isn't helping either. Both cameras have a similar purpose as travel cameras but they have substantially different lenses. If you go from a prime to a zoom you will lose IQ. That is an undisputed fact. To go from a 3x zoom to a 7x zoom will see the 3x sharper than the 7x. Again it's accepted. The RX100M6 has 8x zoom, the TZ200 has 15x zoom, virtually twice as much, yet we get constant comparisons.

I have concluded that they are acceptably close in IQ, but to expect the latter to be equally as sharp as the former is crass stupidity. However Panasonic could do a lot better with a higher level of Q.C., of that I'm sure

VERY interesting in view of so many instances of "one-edge-soft-focus" reported on this forum.

I'm not sure about the ZS50, or other newer cameras, but with an older Panasonic I cleaned for a friend. I noticed that pictures could be taken with the lens/sensor unit sitting on the disassembled camera, looking off to the side, could function to take pictures.

Possibly a camera with a "soft edge" could be set up in a similar manner so the 3 screws can be accessed, and adjusted until the image is sharp all over, then re-installed in the camera. Perhaps this is what you did?

Maybe a drop of glue or fingernail polish on the screws to keep the adjustment permanent.

It could be worth a try.

I must say, it is very easy to open the camera, so you can access the three little screws. The adjustment I did was more trial and error, and I had luck... :-) It should be possible to adjust the screws while looking at a screen, I do not know...

Yea - it includes a Panasonic model decoder ring!

It gets worse! What's the difference between a ZS100P and a ZS100PP?!!!

I thank you too. I have taken apart and reassembled 4 different Lumix cameras, including my old TZ6 (clean sensor), TZ30 and TZ70 (miss behaving zoom control ). I also own a TZ100 which is working fine, but the service manual may be useful in the future.

I found in the service manual the procedure to calibrate the level sensor. My TZ70 level meter is slightly out, so I need the service manual for the ZS50 (TZ70) to get into the service mode and fix it.

Any assistance will be appreciated.
 
I disassembled my DMC-zs50 to clean grit out of the lens. The cleaning and reassembly went well; the camera take pictures, zoom works, but focus is erratic and sometimes fails altogether. Also, even the best photos using spot focus under ideal conditions do not have the resolution this camera was known for (ie. even a little cropping loses definition). It is like the camera has forgotten how to focus . I have the service manual which covers all the measurements and adjustments. Is this something one can take on at home? Or is it worth sending in for servicing?
 
I would give it a try if you feel confident enough. Even if you make it worse, you can still send it off for calibration. If you get it right then you won't need to send it off!
