The DA 16-45 is a very consistent performer, particularly in border to border resolution, which is better than any zoom lens I've ever used. While it's not quite prime good, it's very close. I haven't used any of the other lenses, but I did run across the old Pop Photo SQF tests of the FA 28-105 PZ. Supposedly, that lens is quite superb in the middle of the zoom range (with similar scores to the FA* 28-70), but not as good at the wide and long ends.

I like my Tamron 17-50 plenty. It did need a little AF fine adjustment but you should be able to dial that in fine on your K-5. If you don't want to fuss with AF fine adjustment then get the 16-45.

Answering your questions...

DA 16-45 f4: ~200$
Tamron 17-50 f2.8: ~250$
Sigma 18-50 f2.8 Macro: ~300$
FA 28-105 f4-5.6 PZ: ~100$
There're some review of above lens, but i can't decide what's suitable len for me @_@

My taste:
I like lanscape and macro (or closeup). Some time i use my gear to shot some portrait for my family, but not usually
the cheapest 18-55 ALII can do this;

I want a AF lens which can correct AF when use. I hate my lens back or front focus @_@.
AF for sure.

I know the yellow tone in images taken by Tamron, but it's ok with me.
Change the WB or LR/PS it out.

I offten use f5.6-8 when shotting, althought i have Super takumar 50f1.4. When shoting in low light, i'll use flash and tripod.
there will be no bad lens @ F8. And for landscape, I always think F8 is the best choice. These two assumption========》 most lens can do it.

I want my images are sharp, very sharp
Most zoom lens will let you down. However still depends on the F step

I want my images are full of color, even b/w images, lol
Again, you have K5, use the in-camera filter, or PS/LR the contrast.

And there're my situation :
I was used tamron with canon a year ago, and i like it's build. But when it has been back/front focus, i tired and sold the lens.
I never hand on DA16-45, so i wonder if it's build like kit DAL 18-55 or not?
From my experience, could be lightly better. I kept 18-45 for 6 months. It provides good quality, however I cannot see a $200 difference between them. The 18-55 is smaller/ligher, and step-down to F8-----all on the similar level.

DA have 16mm, it's good for landscape, but i don't now IQ when shot at 16mm with K5
Again, it's okey. However compared with DA 15, it is not that good.

And i readed some where that DA16-45 have issue with flash @_@
With in-camera flash, exactly. With hot-shoe flash, NP at all;

I like the sharpness of Tamron but i scare it's AF issue
Tamron I only used A001. It's okey.

I don't know the color tone of Sigma, it's better than Tamron, DA16-45, or not???
Haven't tried Siggy. But I own SIGMA/DP1. It used to be $250 on amazon, and it can blow most zoom lens away by its monster APS-C sensor.

FA 28-105 f4-5.6 PZ is sharp, good build, and sheapest. But seem only sharp at center
Beware of the FA era purple fringe and CAs from the FA lens. You need to PS/LR them out anyway.

So, i want to collect comment here to help "bright my head" and choice suitable lens
Thanks all

Okey here is my conclusion:
1. Between DA16-45, Tamron A16 ( i think it is the model 16-50/2.8?), DA 18 55 AL II and the FA one: pick up the DA18-55 if you have a limit budget ( a used one will be around 50~70 USD). If you don't have a budget limit, think about the A16; If you don't mind ZOOM/FIX, go for DA 15;
2. If you don't mind put another monster camera with you, think about SIGMA DP1X. 35mm equivalent =28mm, good for LANDSCAPE. DP1X+18-55 is my current setup.

There is something I think that benefits me: For wide lens, go fixed; for teles, go zoom.
Hope the best,

Da16-45 or FA28-105 f4-5.z powerzoom

I have both these lenses and both are unique. The prices you're talking about are really good . The 16-45 should be your best bet because it is all around great.
It would be good if you have a little more reach.. The 28-105 would give you that, along with great image quality and works very well in automatic. I find that the 16-45 is not a very long zoom. So when I go out shooting
fall foliage at end of month I"m bringing it along because I know it will give me great results if I need a little more reach.. And for $100. I would not hesitate to buy it. 20+ years old, but very well made: heavy and reliable.
Don't worry if the powerzoom doesn't work. just turn it off , set the lens to "A" position and shoot away in automatic. Those vintage lenses have amazing sharpness and image quality and are very special.
Good luck. Freddy
