"Uncle" was a term that meant "I've had enough, stop now" in bygone days. Ah well...
Time to pull the plug on lens changes ASAP. I let the 18-135 go, as the recent hike made it clear that in good weather I'd prefer primes. I picked up yet another 18-55WR for foul-weather shooting; this not only good enough for me but nicer on the lens fund and much more compatible with my 52mm filter set!
A few others can go now too, though for the price of postage it might not be worth the effort - but we'll see. A couple of other 50mm lenses should go besides the macro - though perhaps the 50mm/1.7 'A' or f/2 'M' lens should stick around for times when f/2.8 won't do. Given the hi-ISO talents of the K-5 though, those times are impressively rare!
So today's roster, sorted by filter size:
49mm* - DA40, SMC-A 50/1.7, DA70, SMC-M 135mm
52mm* - Rikenon 28mm + 70-150, SMC-M 200mm (all fully manual), DA18-55WR
58mm - DA55-300
nosuch - Sigma 15mm fisheye
* I have a 49-52mm step ring so I can pretend these are equivalent. Somewhere I have a 52-58 step as well, if I really feel like leaving filters at home!
