Choosing a Lens

Howdy, all!
I have a Pentax K100D with kit lens, 50-200mm and a 50mm 1.4. As well, I have a Phoenix 100mm, but I'm not really loving it. To get true macro from it, I have to attach a 1:1 screw-on magnifier. It's a clunky, noisy lens, but produces decent photos when I actually do pull it out to play. From all these lenses, I find that my 50-200mm is on my camera the most, then my 50mm. I admit I like the versatility of a zoom.

I would like another lens or two and I'm having a hard time deciding which one[s]. My favourite thing to shoot is macro. Winter doesn't give me many opportunities to do so, but once spring is here I get out and shoot a lot more. After macro, I'm into outdoors shooting. Not lots of landscapes, but shots at our cottage, family snapshots, etc. I rarely shoot portraits and rarely shoot indoors, but I do on special occasions.

So, I'm thinking these might suit my needs and I would like your opinion!!! Based on my criteria above, what do YOU think? Any comments or suggestions are welcome!

- Macro lens - like the Tamron 90mm or the Pentax 100mm.
- Wide angle - like the 10-17mm or the 12-24mm
- 18-250mm [ this would eliminate the need for both the kit lens and the zoom I have]
- 28-300mm [Tamron] - same as above

I don't know how much of a response you'll get in here, since a lot of the people in here are still beginners, but I'll give my suggestion. If you really like macro I'd go for the Pentax 100mm, from the reviews it is a solid piece of glass.

The Pentax 100mm macro is a great lens. I don't get a lot of use from it in the winter also, but I guess I could be imaginative and give it a whirl to see what I can do.

I just recently purchased the DA 16-50 2.8 and took it with me to Hawaii. That lens was definitely my favorite and on my camera most of the time. Great for landscapes as well as for the more snapshot type of pictures. The focusing motor is super super quiet. It's a really solid piece of glass IMO. I'd definitely recommend this lens for a great all around lens.
I also got the 18-250 thinking it would be a great carry around lens. It's a good lens, but not as good as the 16-50.
For fun you can't beat the 10-17. It is a fisheye and an awesome lens. I wouldn't use it for an everyday type of snapshot lens though...unless you are into that.

So you must have got a good copy of the 16-50 then? A lot of people have been getting bad ones. So bad it doesn't look sharp anywhere in the picture. Some people have had to ship their lenses and get new ones from Pentax 4 or 5 times before they got a good one. If you got a good one I think you are lucky. I have heard that lens is awesome, unless you get a dud. My next lens will be the DA* 50-135.

I guess I got a good one. You can be the judge. The pic I submitted for the challenge was taken with it and only minor sharpening in Lightroom was applied. I'm always afraid of the good copy/bad copy thing. I think I've been lucky so far. Watch the next lens I buy is a dud. Or maybe my eyes are so bad I can't tell if it's a bad copy LOL.

Over at pentaxforums a lot of people are complaining about it right now. There are some that got a good one right off the bat, others had to trade a few times, some are in the middle of trading them in right now. From what I have read it is obvious if you have a bad one, so yours is probably good. Your shot looks sharp, but it is harder to tell with a low-res version.
