Of these I have purchased and sold #1. Which ironically you say that you kept. The FA 35 f2 I found more satisfying.
I also sold off my copy of #4. It was purchased in a kit with a K100d super and an 18-55. Both lenses are long gone. But they served me well when I first got back into digital.
I still own and have no plans to sell #3,#5,#6,#7,#10. Technically my #5 isn't the same, mines the older DA55-300 without HD or WR.
If you're not getting good shots from the 18-135 I'm not sure why, there's an entire thread on this lens that shows how versatile it is.
As for the 55-300, that's a good albeit slow and noisy lens. Every version is pretty good. The alternatives are expensive and most have limitations (Size, cost, focus speed)...
The FA 50 is an interesting lens, once stopped down to f2.8 it is very good, before that it can be used for special needs. Wide open it is very soft which can be useful but is mostly annoying. Still it is small and can go into dark scenes with a lot more light than many lenses.
The DA* 16-50 shows some age on the wide end. It isn't bad, just isn't as great as the rest of the range. Plus sdm issues and it gets moved more often. My copy is screw drive and was obtained cheap.
The DFA 100 is a great lens, but it has two glaring issues. 1) no focus limiter... This makes using af a real pain in some situations. Coming from there F100 macro that was sorely missed. 2) no aperture ring (the non WR version haas this at least). Not having an aperture ring limits the use of this lens with bellows and stacking or reversing. Some would also bemoan a lack of a focus clamp but that never bothered me.
I rarely use my FA 50 since I own the DA* 55 F1.4 and F 50 F1.7.
The prices on some of these like the DA 55-300 have crashed in recent years due to changes in the market. The highly desired 55-300 PLM has driven down the price to the point it isn't worth selling for me.
