My Panasonic DMC-GX85K locks up after 20-40 exposures when used on electronic shutter with my Olympus 17/1.8 lens. When this happens it is necessary to cycle the camera on/off or remove the battery to get the camera to resume functioning. The camera works perfectly with the Panasonic 12-32 lens it came with. I wrote about this problem previously in this thread: Panasonic DMC-GX85 Refuses to Fire Sometimes I sent the camera and lens to Panasonic and then Olympus. Their service technicians were able to recreate the malfunction but both blamed the other company's product and suggested that there may be a marginal incompatibility between the camera body and lens. Is this explanation plausible? I found no reports of this issue in online searches even though it seems likely that many people use this camera and lens combination. In any case I need to decide whether to live with the problem or perhaps throw good money after bad by replacing the camera body or lens. (I would use the Panasonic 20mm if it had faster autofocusing.) Any suggestions? Thanks.

Thanks for the reply. I will try your suggestion. I notice that when the problem I described is occurring none of the usual lines or grids or other indicators that I have the screen configured to display are actually displaying. So perhaps there is a software or hardware issue.

Hi All, My GX85 eventually stops displaying autofocus boxes or making exposures when I am in the midst of taking a batch of pictures. I press the shutter button and nothing happens. Then I turn the camera off/on and this resolves the problem until the next time. I use live view exclusively and mostly an Olympus 17/1.8 lens. Shutter is configured for half-press and either mechanical/electronic or electronic actuation only. I changed the settings to allow exposure without locked focus but doing this made no difference. I think this problem occurs most frequently in low light but it could be that that's because I take most of my pictures in low light. I can't tell if the camera is faulty or if I simply need to change a setting somewhere. Does anyone have any ideas as to what may be going on? Thanks.

Probably 3200.

A friend of mine has a roll of 35mm Tmax 3200 that was exposed perhaps 20 years ago. Can anyone suggest a developer and developing time that would be most likely to yield usable negatives in this situation? I realize that this film doesn't hold up well over time if undeveloped, but we have nothing to lose. Thanks.

<p>Thanks, Dick.</p>

<p>I have a new EOS-M and 22mm lens, firmware v. 2.0.2, always configured for auto-white balance. Occasionally the WB of the camera's LCD goes out of whack and both live-view and images replayed from the camera's memory card display with a bluish or reddish cast and sometimes too dark. Changing the camera's WB setting has no effect. The problem always goes away eventually, usually if I turn off the camera but sometimes only after I remove the battery. (This problem only affects image display on the LCD; the actual saved image files, both RAW and JPEG, are fine.)<br> A Canon rep told me that based on my description there is definitely something wrong with the camera. If that's the case I can return it to B&H. However, before I do anything I want to find out if this is a known problem with the EOS-M. Has anyone else experienced these issues?</p>
