Hi Faith,
I own a DL and have for about a year now. This camera has served me very well. I have never had any problems camera wise (Oh a dirty sensor and focus screen but this is normal) I'm not going to tell you to trade the DL that has to be your decision. I will tell you that a second body is always a good thing to have around. On photo shoots when you need a lens change and don't really have time or you want another perspective, always great to know that other camera is ready to fire and get the job done.
I preordered a K10 months before they came out and was waiting and hopeing for it to arrive soon. Two weeks ago the shop I ordered it from packed up and went out of business with no warning. They returned my deposit and I was crushed not only to find out the shop was gone but also realised I wouldn't be getting that new K10. I have since had some time to rethink my shooting and my camera needs. I have finaly come to the conclusion I don't need 10 mp. (yes it would be nice but...) and all the bells and wistles. I'm not a pro and I never expect to be( however I am a good photographer and am experienced in many forms of photography, Landscape, nature, portrait, and just plain fun shooting.
I finaly decided I need the shake reduction (I'm getting old) and I do find my self in low light situations. and I want the 11 point AF And I won't have to buy a new computer (that's what my wife thinks
) to store al those gigantic files on. So as I said the rethinking helped to decide to get the K100D and I'll have that for Christmas (or soon after) untill then I have my trusty DL and I will never get rid of it. I will always be glad for Two bodies.
Good Shooting.
Cheers: David
