Pentax 16-45mm or Pentax 18-250mm

Which of these lenses should I buy. I understand the 16-45mm f/4 is a super sharp lens. I'm expecting that the 18-250mm f/3.5-6.3 will be a great performer as well since its Tamron cousin has received rave reviews.

I currently have these lenses in this range

Tamron 28-300mm f/3.5-6.3 (I use this when I only take one lens)
Tamron 28-75mm f/2.8 (really sharp and fast)
Pentax 18-55mm f/3.5-5.6 (kit lens)
Pentax 50-200mm f/4-5.6

If I get the 16-45mm it will give me a great lens with some some really nice wide angle and will replace the kit lens.

If I get the 18-250mm I wont get as wide an angle but I can replace three of the above lenses. selling those lenses will help with the cost of the new lens.

Of course I'm going to keep the 28-75mm f/2.8 either way.

At the wide end the 18-250 is a f/3.5. The 16-45 is constant f/4. So speed below the 28mm of the tammy i'm keeping is similar.

So what would you guys do? Is there really much if a diference between 16 and 18mm? Is the 16-45 such a great performer that I should get it and keep the longer lenses? Or would I be better off getting the 18-250 and replace three lenses with a great performing all purpose walkaround lens?

Yes I would like to get both but that's not an option at this point.

I should add that I also have a Sigma 135-400mm and a Sigma 50-500mm to cover the long end as well.

Do you find yourself using the 28-300 a majority of the time? If so, get the 18-250. However, if you are looking for a super-sharp 'normal' zoom, the 16-45 seems to be a wonderful choice (see this thread for more praise about the 16-45). I don't own the 16-45 myself, so I can't really comment on it's performance, but the general thought seems to be that it's a great lens.

It really comes down to what you need. If you want something a little sharper and a little wider than the kit lens than the 16-45 is your guy. if you're looking for an all-purpose zoom that will go a little wider than your 28-300, go with the 18-250.

I vote the 16-45. Swapping lenses in the field is easy and the 50-200 is tiny.

I was really leaning toward the 18-250 since it seemed to be the simpler solution but after reading the 16-45mm thread and all the glowing reviews I went ahead and bought the 16-45mm. Now I just have to sit back and wait for it to be delivered.

Thanks clawhamemr and SupremeMoFo for answering my post.
