A reader writes in response to my lenses as an investment:
Lenses like those in your "world class" category, superbly crafted manual focus lenses with aperture rings, certainly, and especially when they can be purchased in excellent condition at a great discount.
But I'm wondering about the expected longevity and adaptability of the newest Nikon lenses for the reasons, for example, given in the some online posts (plastic, electronic, motorized lenses, lacking an aperture ring, unreliable (based on LensRentals.com experience), restricted spare parts to put independent repair shops out of business, reports of "nightmare" warranty repair refusal due to "impact damage" and of refusal of paid repairs based on serial number, difficult to adapt to other camera systems unlike Leica R and Contax C/Y lenses that were able to outlive their systems to retain their value):
Or for that matter, if the Leica S2 system has no S3 successor (or an S4 ... after that), can those spectacular lenses that lack aperture rings (and do they have sufficient retrofocus) to actually be successfully adapted for use on other systems, like the Hasselblad V lenses can?

If we have an EMP (electromagnetic pulse), anything electronic will die. And then there are other worries more fundamental. So I suppose one can take things as far as one wishes in terms as worrying about the worst, but I don’t sit around worrying about the worst.
I wholeheartedly agree that the trend to electronic lenses is a step backwards. The idea of updating firmware in a lens is atrocious. Nikon has taken a HUGE step backwards with its “G” lenses, rendering them useless on Canon and other platforms, unlike millions of prior Nikkors. A very good reason to invest in Zeiss ZF.2 instead.
The older Nikon (non-G) and Zeiss ZF.2 lenses can be used completely manually, so they are good forever. Ditto for Leica M, Leica R and Voigtlander for Nikon/Leica. And this is why Canon EF, Zeiss ZE and the newer Nikon “G” lenses (no aperture ring) SUCK for longevity— they either cannot be used at all cross-platform, or at least not without a special electronic adapter, many of which have various issues.
So if one wants to invest in the best glass, and one is willing to tolerate full manual focus and aperture, conventional lenses with a manual diaphragm (Zeiss ZF or ZF.2, Hasselblad V, Leica M, Leica R, Voigtlander for Nikon or Leica, etc)— those are the lenses to invest in. And the ones least likely to need repair (in my own experience). And the ones I deem most likely to hold future value.
Zeiss ZF.2 lenses can be used (by virtue of the mechanical aperture ring) on Nikon, Canon, Sony, and others. And they a great for video on Canon, with full manual aperture and focus.
As far as Leica S lenses, yes, they suffer from excessive future-creep including lousy manual focus feel— I wish they had been designed with a manual aperture ring and a helicoid and were thus adaptable to a Nikon or Canon body. Perhaps there is an adapter out there. But at least Leica is now quite profitable, and thus there is little chance of a service problem.
