As said in a previous thread I lost my d50 and will be buying a new one with the insurance money. Well me and the wife were thinking about upgrading to the d80. I then got to looking at the d40x. It is almost $300 cheaper than the d80 and comparing them side by side the only difference I could truly see is the d40's lack of an internal AF drive motor. All the lenses I am looking at getting, there is another thread in this forum, are AF-S except for the 50mm f1.8 I was looking at. So is the extra $300 for the D80 justified. I pretty much shoot whatever I see. I am too new at this to have something I specifically shoot. The main reason for the upgrade was for the greater ISO capabilities. The D80 will give me 100-1600(3200 with ISO boost) in smaller increments. the D40 will give me 100-1600(3200 with ISO boost) in increments of 100,200,400,800,1600,3200. Is the smaller incrementations os ISO better? I really want to get as much camera as I can since I don't plan on buying a new one for a long time. I really don't mind spending the extra $300 but I want to be able to justify it. Thank you for all your help in advance.
