Originally posted by philbaum The DA 300 will fit those requirements. And its F4. The 18-250 very quickly gets to F6.3 when its out at max tele. And thats when you need a faster shutter to get a non-blurred image. It weighs 34 oz, excellent contrasty images and great bokeh if that matters. And its water proof/resistant whatever. And its handholdable, it easily doubles the 50-135. It also gets great images when attached to a 1.4 Tamron TC but you loose a stop of light with the 1.4 so i don't normally use it. Also, i think these lenses have good resale value so you would not have a problem selling it, but i'm keeping mine :-) The con to this lens is you need a backpack style bag to carry it, or perhaps a special holster style.
I have the Kata 3N1-30 and it should fit fine. I am actually looking at the DA*300 due to the weather sealing, f/4, and high quality glass. I just have to get past the fact that it's not a zoom lens. As you can see from my signature they are my preference.
I just wish that Pentax made a 100-300 DA* zoom. That would be perfect!

Thanks! This is very helpful!
I did go outside on lunch today and try focusing on a far away tree line and the angle of view from 135 to 250 was much more apparent to me.
