I am so confused as to which SLR to get. I have never had one before but have always had SLR like cameras such as the Sony DSC-H5. I like that the Sony Alpha has image stabilization built into the camera, but is this necessary? Will a non stabilized lens and the Nikon or Canon be ok. Can I live without IS? Also my dad has an old Canon SLR and tons of lenses from the 70's. Will these lenses fit the Canon Xti? That would be great cause I would not have to buy additional lenses other than the kit lens! Of course since they are 30 years old they are not image stabilized. Has much else changed with the lenses since the 70's other than IS? If his old lenses will fit and I can do without IS then I will prob go with the Canon Xti. I have always had IS in my cameras, so i'm a little nervous about not having it cause I usually do handheld shots. Any help would be great!! Thanks.
