It's reassuring and encouraging at the same time to read your sharing. At least I know I'm not alone in the "How can I utilize my 20+ lenses and 3+ camera"
and I agree with you, we have got to the point where our lenses are not purely necessity for our photography (from hobbyist perspective, I don't know how pro guys do), but also they are collector items, they bring emotion, they have stories, and it's quite hard everytime I have to part with one. For example I got my Super Tak8 elements from and old lady, her husband passed away, and he was a respected photographer in the past. The lens is a beautiful object, it has a fascinating story of Pentax vs Zeiss, it's older than me, it was own by an old photographer before, and I'm almost certain it has seen people, places, stories, ups, downs ... much more than what I've been through. Just thinking about that, I already love the lens so much, though admittedly it gets used just occasionally, and its main job is to ... sit on a shelf above my working corner, with a black Spotmatic, as a decorated object.
Not all lenses I own bring me that emotion, but it's true they have their own story, reason of why and how they arrived here. Some of them give me great photos, great memory. On the other hand, while the idea of collecting lenses by the time is great, I have to also rationalize between my hobby and the financial responsibility to the family, hence I have had let go quite a few lenses, some of them really good, even rare and fit the "collector" norm even better. Still, my overall line up has grown along the time, and reaching this point, owning these 21 lenses with 2 cameras, I started practicing photography for the first time just 3 years ago. Will I have 42 lenses and 4 camera in another 3 years time
