Oh Yes...my Sony S70 which is a digital 3.1megapixel which is already 4 yrs+ and going on 5 yrs and still going strong and is my backup camera to my D70. Accidently melted abit of the front lens casing hehe....it was all fogged up when I brought it out from a cool room to a normal room temp. So I use a shrink wrapping hot air blower to warm up the lens..it was so hot it started to melt abit of the plastic covering on the front element and near the battery compartment hehe...but but it still works fine. Only had to send it in to the shop once to get rid of a fungus "dot" on the CCD. Never was placed in a vacuum box all these years too...kept in a photo bag when not used or in the office which is always air con. I guess I have already got more then my money's worth but it still keeps on ticking...not bad actually. I expect it will last another few years easy looking at it presently.
If my previously electronical cameras like my Nikon EM, FG and FE2 which I kept the longest..tey are all so called electronic cameras but they were still around and working fine. Back then there were also detractors who claim they will never last as well as the fully mechanical ones but there you are...the electronic ones are still chunging along...with the digital ones..it is still too early to say and it is almost exactly where I was when I bought my first Nikon EM. IN fact I had the first electronic AF model from Canon...can't recall the model now..it was the first all dark colour one with all the plastic lens..bought by a compay I work for to use for our inhouse shooting....it died after about 3 yrs of use heheh. Had the FA, F3HP, F4s and F5..and well these models goes without saying..they will last a long time. But since I buy and sell these models the most compared to my older earlier collection, I never had them more the5-10 yrs but I am sure there are still working somewhere with those folks I sold them to heheh..not surprise they have gone through a few other buyers too. Guess that is why I never stop buying Nikon.
The leica are legendary I am sure but that is a difference "tax" bracket ...heheh me pockets are not that deep.
