Hello All, I have always had a liking for photography ever since I saw the first camera. At early days I had a Yashica film camera. Then 4 years back I got a HP camera with Pentax lens. The HP was very good considering the shots a novice like me takes. However unfortunately I broke it while trippiing over a stone. The damage is to the lens and the motor unit I guess and it would take almost 60% of the cost of the camera itself. So for now I am not inclined to touch it. I have been thinking of getting another one but a digital SLR this time. My budget constrains would be around $600. The problem is that I am not able to compare camera's due to the lack of the knowledge on the technical specifications that the web sites give. All I would need is that the camera fits my budget, would be compatible with lenses (i would be investing in the future). With this knowledge when I researched I came up with Nikon-D40. But a few ppl suggested NOT to buy this.Not sure if its because of the lenses compatibility with camera. The other one would be the Nikon D-80 or Canon 350/400. Would you suggest considering any other models? Appreciate your response.
