Untl I purchased a K20 I was a staunch Leica user. My rangfinder was made 30 years ago and my SLR about the same. The lenses are at least 20+ years and are absolutely fantastic to use. I feel in love with my K20 also outdated. Leica has dropped all production on their R series equipment and have abandoned those users in faver of a $28,000 S series digital with a starting price for a standard lens at $5,000+
Pentax IMHO has not abandoned it clientel, in fact has tried and suceeded in producing quality equipment and optics that rival the best. Yes there is a definite something to leica images and I still use the equipment.
I am an Audiologist by trade and the hearing aid industry upgrades and introduces new digital aids on a quarterly basis-that's just the nature of digital technology and hearing aids. Digital cameras are no different. Despite my love of leica equipment my K20 will only leave my cold dead hands ....or maybe for a K7
