So I've read through some current threads and am looking for somewhat the same answer, slightly different circumstances.... I have a Nikon D70 and am mostly taking posed pictures, such as weddings, engagements, senior portraits, babies, etc. I have the standard equipment that came with the D70 kit, lens and body, and bought an SB-600 flash. I also have a 70-300 Vivitar lens that I had bought for my N65 when I worked at the local newspaper, but I haven't been satisfied with the output when using it on my D70. Question is - in recent threads some have been posting about getting better lenses than putting money in a newer body, which I'm very receptive to - I like the camera but the output is to be desired, although I'm still learning. My digital pictures are grainy and not always sharp when I zoom in on them in Photoshop to look at detail. Some of you have mentioned that it would be wise to invest in a better lens to remedy this. What would you suggest I should invest in for my D70 for better pictures?
