I have the Pentax version of the 18-250. When it was on my k20d, it was a great lens. On the K-7 it is still great optically, but now it focusses faster!

I must have gotten a really good copy of the 18-250. I have tested that thing against everything I have. I keep going back to it because it is so good. You would think that it being a "superzoom" it would have IQ compromises, but I am just so impressed with mine. My copy is amazingly sharp even when compared to the DA* 50-135. You have to go to 100% crop to even see the difference. Whenever I take pictures outside now, I keep asking myself: "why should I use anything but the 18-250 since it is so convenient, and you can't see the difference between any other lens?"

The 18-250 is what is attached to my K-7 now. The only complaint I have is the lens creep, so you have to lock it when you are not holding it. Also, it is an optically "slow" lens, but that is the compromise you make when choosing a lens with such a wide range. Distortion is easily corrected with PTLens, or now in-camera with the K-7.

thanks, so you can correct distortion with a non pentax lens?

Yes, with PTLens you can, but I haven't tried it in-camera with any other brand. I have "heard" that some people with the Tamron 18-250 are able to do it, but I haven't seen it confirmed yet.

Yes! That is an area where the K-7 is a big improvement.

DA*16-50 & DA*50-135 replacing the DA18-250?

dafiryde - It's a little off topic, but I'm buying a K7 and I'm thinking about getting the DA*16-50 and DA*50-135 as a "faster" and "weather sealed" alternative to the DA18-250 and I saw that you have both from your signature. How much would you say that you miss having the 135-250 range of the DA18-250 compared to the DA*50-135 If you had to use the DA*50-135 and DA*16-50 lenses exclusively?
