With today's announcement that Sigma will finally release their updated version of the 30mm f/1.4 Art prime lens for Pentax K-mount, I'm now trying to decide which lenses to get rid of to fund that purchase. Due to my lens hoarding tendencies, however, I may very well just add the new lens without subtracting any, but my wife (and limited bank account) would certainly prefer if I got rid of some overlapping lenses.
My current prime lens lineup is:
DA 15mm f4, DA 21mm f3.2, Sigma AF 24mm f2.8 Super-Wide II, smc Pentax-F 28mm f2.8, FA 35mm f2, DA 40mm f2.8, FA 43mm f1.9 (MIJ), FA 50mm f1.4, DA 70mm f2.4, D FA 100mm WR f2.8
In order to clear space for the new Sigma 30mm f/1.4 Art, I think the primes I'd put up for sale would be: smc-F 28mm, FA 35mm, and FA 50mm. Maybe even my DA 40mm limited even though I enjoy that compact little lens' fast AF and image quality. (It's been hard keeping both FA 43 and DA 40 but I love both for different reasons and would be sad to get rid of one).
Should I do this? I think of trades in professional sports, specifically basketball, and how a team could trade 3 good players to get 1 all-star, super-star player. But I'm afraid I'd regret getting rid of some of my favorite primes: my FA 35mm is very good optically, lightweight, and compact, as are my F 28mm (so sharp, small, and light) and FA 50mm (a sentimental favorite as my first prime lens). Certainly the Sigma 30mm would replace the F28 and FA35, while my FA 43 and DA 70 can easily take the place of my FA 50mm as a portrait lens. (And my love/needs for f/1.4 capability would be met by the Sigma, at a more "convenient" focal length on APS-C than the FA 50).
Note: Full-frame compatibility is not a concern for me, so me getting rid of 3 FF-capable lenses for a APS-C only digital lens is not a big concern. And yes, I could also sell off the 3 lenses to try to get a FA 31mm limited but I prefer the f/1.4 and HSM motor of the Sigma 30 art lens, plus it's at least half the cost.
Any suggestions/feedback would be appreciated!
