My passion for Vintage Glass ...
I have a passion for vintage camera lenses from the 1950's to the 80's, could be Leica, Nikkor, Carl Zeiss or old russian glass. I especially like their very unique texture and how they add something to the pictures. Way much softer than modern glass, they tend to be warmer and more subtle than the modern "cold as ice" look!
I even do love some of their optical defaults, or what lens specialists might call "aberrations"! It often add a lot of charm and a lot of complexity to the final shot. In a way you can compare vintage lenses to old mechanical whatches against modern "cold as ice" quartz, vinyl records against digital, and so on.... (yeah I know I'm kind a old school fellow)
All of this lenses are part of the History of XXth century, some of them were created during the war effort, some other used by NASA for the Gemini space exploration program, while a huge proportion of them served during the Vietnam war for photo journalists. All of these lenses did make it through half a century and through the toughest conditions a photo camera could encounter!
I got to mention that almost all of these lenses have a very unique story related to their manufacturer or to the optical engineer who designed their optical formula! Either they were conceived by Walter Mandler, the genius behind most Leica designs, who invented the aspherical lens element while some other were designed by Carl Zeiss whose optical formulas such as Planar, Tessar, Sonnar and Distagon are more than 100 years old and have been copied by many lens manufacturers.
