My collection is getting a bit out of hand, pretty much all of them I would consider "wanted", certainly not needed.
I have a K1-II and a K3-II (+hardly used MX and Z-1P) and mainly shoot street/travel
Pretty much all lenses were bought second hand.
The list
DA 15 (apsc essential)
DA 21 (ditto)
DA 35 (which one? If macro, ditto above)
DA 40 (fun, but not essential if keeping 35)
DA 70 (HD or SMC? If HD, I'd keep, the 77 might struggle with some lighting that the 70 will handle due to coating and narrower aperture. )
DA 20-40 (if keeping the da21 this is on the fence, it's a great zoom, and WR, but it might be possible to say goodbye to, on the other hand it's a good walk about lens for travel)
DA 55-300 WR PLM (do you travel with apsc? If so essential)
DA* 55 (apsc essential, and nearly ff in a pinch, lighter and more travel friendly than the DFA 50)
DA* 200 (good lens, versatile length on both formats, how often do you use it with travel and street photography?)
DA* 300 (see above, less versatile, more specialized, same questions on use.)
DA* 16-50 (unless shooting a lot of low light with apsc, it's a luxury, but not essential)
DA* 50-135 (hard not to keep, best zoom lens for apsc portraits and versatile short telephoto, but not a great travel or street lens)
DA TC 1.4x (luxury, unless you are shooting extreme telephoto there's no reason to keep)
DFA 100 macro (keep, ff and apsc macro, but this didn't appear to be your focus.)
DFA 24-70 (essential only if low light is a concern, but superb)
DFA 28-105 (must keep if not keeping 24-70)
FA 20 (ff da 15, must keep)
FA 28 (not essential, fa 31 is close enough)
FA 35 (lovely and compact, less obtrusive than the fa31... Tough call, the HD version might be essential...)
FA 50 (which one? Keep either f or fa for lightweight compact travel or street use)
FA 135 (nice lens, but if telephoto isn't a focus...)
FA* 24 (I don't recall shooting this lens but comments are mixed, how often do you shoot this wide with a prime?)
FA* 28-70 (see DFA 24-70, definitely keep only one of these)
FA* 80-200 (fine lens, nearly essential on ff, but the 70-210 DFA is smaller and more travel friendly ..)
FA ltd 31(essential)
FA ltd 43 (if keeping, dunno the f and fa 50?)
FA ltd 77 (essential)
F 28 (nope)
F 50 (see fa 50 and 43)
M 28 2.8 (only if the mx is going to get used)
M 50 1.7 (see above)
M 135 3.5 (see above)
If you think anything is missing, I'm curious as well!
(from a collection point of view I would say the FA*85, DA*11-18, DA*60-250 and any missing current DFA lenses, I'm not really interested in tele stuff)
