Good afternoon Bing,

Thank you for your email, Leica in Solms has forwarded your email to us as their Australian representative and asked us to provide the answer.

Unfortunately there is no current fix available for this problem. We understand that the Product Management team at Leica are investigating this issue and could have a fix for it soon. Any fix would be be included in future firmware upgrades which are available on the Leica web site. Perhaps we could advise you to check this site from time to time and also subscribe to Leica's email newsletter. This newsletter usually advises its subscribers of firmware changes.

I hope this is helpful.

Details of inquiryHi Support

I am a Leica D-LUX 4 user from Australia. I recently found an issue of Auto Review that, I think, should be a defect of D-LUX 4 firmware, which is inherent from the LUMIX firmware of Panasonic DMC-LX3.

The issue is: while Auto Review is working on the "HOLD" option, the aperture is on hold, too. That means, the lens does not return to full open aperture after shutter fired until Auto Review stops showing the last shot. The issue also applies to the other options of Auto Review, of course, except the "OFF" one, though the duration is less than 2 seconds with other options ("1 SEC" / "2 SEC" / "ZOOM").

This is really not good for the lens, one of the most expensive parts of the camera. The aperture of this lens should be better at the wide open position while not at work. As you know, the aperture is fully opened when the camera is power off.

As it is not necessary to keep the aperture working while reviewing a photograph because the shooting procedure has finished, I speculate it should be a defect of the firmware, and hopefully it can be fixed in the near future.

At present, my fix is just to turn OFF the Auto Review, at all. Do you have any method to get rid of this issue?

I am looking forward to hearing from you about Leica opinions on this. Thanks in advance.

Kind regards,
Bing Bao
