I already have, * indicates my usual walkabout kit. The others (#) live in another bag, the rest in my cupboard.
Zooms:
* DA 16-45 - My most used lens, may replace with DA* 16-50 (see below re: the 24 & 35 primes)
* FA 28-105 f3.2/4.5 - not used so much now, may sell.
* Tamron 70-300 LD Di - Will be replaced by DA 60-250 (if it meets expectations)
Tokina 20-35 f3.5/4.5 AFII - optically equal to the FA 20-35 but big, may sell.
Primes
# FA*24 f2.0 - If the DA* 16-50 is equal at 24mm from f2.8 upwards, then it may go.
# FA 35 f2.0 - Same goes for this one as for the FA*24.
* FA 50 f2.8 macro - I use this a lot, will stay.
# FA*300 f4.5 - Best (affordable
) Pentax tele prime ever? Will the DA*300 be better?
Hartblei SuperRotator 80mm f2.8 (for my commercial product shot work)
TC
* Tamron 1.4x AF - great with my FA 50 macro and FA*300
Waiting for
DA* 60-250 f4.0, or maybe the DA*50-135 f2.8 (and use my TC for a bit more reach)
FA 100 f2.8 macro (s/h) - a maybe, depends on condition and price.
DA xxx-500, if they ever do one!
Considering
DA 10-17 FE or DA 12-24, I actually find 16mm almost wide enough for a rectilinear wide, although I prefer the IQ and low distortion of the DA 12-24 over the DA 16-45 up to 24mm. The DA 10-17 is nice and small and I like the creative shots I've seen taken by others, could be great fun. Maybe I'll just have to get both eventually, but which one first?
Planned line-ups, in my head, which means I'll sell what I already have that's not listed below.
Financially sound (my wife calls this "sensible"!)
DA 10-17 or DA 12-24 (decision time ahead!)
DA 17-70 (if okay), otherwise stay with 16-45
DA 55-300 (if okay), otherwise spend more on the DA* 60-250
FA 50 macro
FA*300 f4.5 - may sell if the DA* 60-250 rocks!
Tamron 1.4TC
IQ based, no financial restriction!
DA 10-17
DA 12-24
DA*16-50
DA*50-135
DA*60-250
DA xxx-500
FA 50 f2.8 macro
FA 100 f2.8 macro
FA*300 - may sell if the DA*60-250 really rocks, or swap for DA*300 f4.0 if it's better!
DA xxx-500
TC's (If Pentax make some chipped ones for Exif and SR)
Pro-grade 1.4x
Pro-grade 2x
Unlike many who really love primes, I don't use them much except for my macro and the 300mm tele, which is where I really appreciate the high IQ, In general I prefer the higher quality zooms, I do find the convenience over the ultimate IQ gain preferable for 99% of my shooting. I guess that I'll put them up for sale sometime.
Yes, I've tried all the pancakes, and the FA LE's, and they are fantastic, but not for me, I guess I'm just plain lazy.
