Best Professional SLR Digital Cameras

I am looking to purchase a Nikon D40 and there are several kits available that comes with extra lenses. I am only just beginning to get into photography and do not understand what each lens does. The camera comes standard with a 18-55 mm lens. But there are kits with 55-200 mm lenses or telephoto lenses or wide angle lenses…

Could someone explain to me what each Lens is used for so I can get a better sense of which lens is the best for me?

I am thinking about attending there are two days of instruction, but it is pretty pricey around $150 each day. The first day is to teach basics on the digital slr camera and the second is about software programs to enhance your photos etc. Has anyone taken these courses, are they worth the price? I am not a complete beginner, just need some additional instruction, would these benefit me?

I have a Minolta Maxxum 7000 with two lenses: a 100-200mm AF lens and the 50 mm AF lens. Is it possible to buy a digital SLR body that I can use my film SLR lenses on? If so, do you know which digital SLRs would work?

I am considering, eventually to make profit with photography, but my budget for now is restricted. Do you think I can start in the photography business with a D70. Which other SLR cameras that can be affordable should I consider?

I am planning to buy my first digital slr camera. In my small business I shoot approximately 60% id photos, 20% portraits and 20% other photos. Price is important but the quality of the camera comes first.

Im young but i want to start early on my career as a photographer and that means i want a good camera. I already have a digital camera and a 35mm SLR. I want a DSLR but is this the right one for me.

I own a Nikon D80 DSLR and I want to know what kind of standard(prime) lens will give me a close enough result to the standard 50mm lens on a film SLR?

I am a teenager and i have a birthday coming up. I am a beginner but I would like to take photography a little more seriously. I dont know much about cameras, but i am highly interested. money is a little bit of an issue, so cheaper would be better. my cousin has a nikon d40x and she loves it. she highly recommends a nikon. what do you think would be the best camera?

I have a point&shoot 7.1 megapixel Sony Cybershot camera, and I want to get a Nikon D40. It has 6.1 megapixel. Should I get it? Is it worth it? Is there a difference between the megapixel and quality I’ll get between the two cameras?

You can remote control big flash units like softboxes. Some SLR bodies have a wireless controller, and you can fire the softboxes remotely using the signal from your camera body. Does the D80 have such a thing?
