whats a good Digital SLR Camera that is affordable?

OK here is my short answer for your price range. for digital I have a Nikon D40 and I love it. The D40 has a full manual mode, Flexible progam, aperature priority, shutter priority modes. These are the same modes on all DSLR. It also has several other programed modes for things like portrait, night, children etc. As a photographer improves and learns to use metering better these additional modes seldom get used so they are usually found on the more amature cameras and seen as not needed on the professional cameras. I feel I have a fair amount of experience as a photographer and it performs well for me but I can give it to my 12 y/o grandson if set on program and he can get good usable pictures as well. His photography is improving as he is already learning to use many of the functions himself ( yes I'm a proud granpa) .

I also would not get caught up in the megapixel hype and instead look at the entire sensor issue. Look at the article I linked below The D40 will do everything a beginner to intermediate photographer needs at a great price. It comes with an 18-55 lens. It will let you use any other money to buy more accessories. And by the time you outgrow it cameras will have advanced to the point that most of what is on the market now would be obsolete. I bought a D300 last year and only had a it a few months when the D700 came out. The canon would also serve you well but I am a Nikon person so I suggest them. I have friends that are very happy with thier canon's and take great photos. You will have others that like Pentax and Olympus and they are not bad cameras but if they were in the same ballpark you would see many more professional photographers use them

Now for the longer answer as you already have some experience I will be preaching to the choir on a good bit of this.

I would say the Nikon D40 Its an entry level DSLR. A digital SLR will give you a much larger sensor than any point and shoot camera. Larger sensor = more light to each pixel = clearer, crisper photo with better color saturation. DSLR will also let you grow and take more control as you learn more and you can change lenses when you have a need to. The sensor on the olympus is smaller than on Nikon or Canon

I am a nikon person and have had nikons since the 70's I personally think the nikon D40 give you more for the dollar than any DSLR today. There are some that do more but you pay a good bit more. Do not let the lower megapixels concern you if you do not do very very large prints you will never notice the lower DSLR. My brother recently needs a DSLR for a class and I recommended the D40 to him So I would also say get the D40 not the D40X. The Nikon D40 does not have limited functions compared with other entry DSLR. Yes it has fewer funtioncas than a 1500 dollar camera body would. It is not a a cut down version its equal or above most any entry level DSLR.

There is a great article in this months Digital Photopro Magazine that is titled "Megapixels how much is enough" EVERYONE looking at buying a new digital camera can profit by reading this article. Its here

I have a d300 and a d40 and when I am shooting for fun I grab the d40. Its weightless, a joy to use and gives good results

If you have a bit more money the D60 give you a number of things you want. It has newer firmware and image processors, designed for the 10 mp sensor. It has an "Active Dust Reduction System with Airflow Control ". Nikon not putting a system on the D40 to deal with dust is one of the biggest drawbacks I see to the D40 ( though I think its still a great camera for the money) If you change lenses dust will get in and the camera needs a system to deal with it. With the D60 you get a VR lens. That will help with low light situations ( they may offer that now with the D40 but originally it was not) . The D60 has Adaptive Dynamic Range. Nikon calls it "Active D-Lighting," it lets you save some highlights that my otherwise be lost. It has a newer better metering system than the D40. So you can get the D40 not the D40 x and spend the other money on lenses or a flash

Some people will want to make a big issue out of the fact that there are some nikon lenses that will not autofocus on these cameras. Right now there are "only" about 39 lenses that autofocus on these cameras. They cover the range of focal lengths. I doubt any photographer would be seriously limited with "only" this many lenses to choose from. If you want to manually focus you can more than double this and do so at a low cost. Manual focusing is easy and how we did things for decades before the advent of autofocus.

Cannon and Nikon chose to put the vibration reduction in the lens rather than the body. Somefolks put it in the camera and make of that. Yes that means you get stabilization only on lenses with that feature built in. In the body in theory it would work on every lens. But in fact image stbilization in the lens has proved to work faster and smoother with a lower impact on focus times than image stabilization in the body/ One problem with in body stabilization comes from the fact that the sensor would have to move different amounts for different focal lengths. A canon white paper says an in body system would have to move the sensor 1/4 inch to account for movement on a 300 mm lens.

Now a comment on liveview. Have you ever tried to hold several pounds of digital camera and lens steady at arms length while you look at an LCD screen. It not at all the same as holding a few ounces of point and shoot camera steady in the same position. One of the things we preach to new photogrpahers is to learn to hold the camera properly so the body mechanics give you a steady shot. You can't really do that looking at the LCD. So liveview is really something that will have very limited applications in a DSLR. . Usually only when its on a tripod. I have liveview on my D300 and have never used it.

Nikon also has great service. I was just reading the other day on eyefetch in the Nikon forum where someone posted that they had dropped thier lens and broken it. It was not a fault of the company they messed up. The sent it to Nikon and Nikon could not fix it. Nikon offered them a brand new identical lens at half the price. They did not have to

In closing all major camera manufactures make good cameras get out and compare the features and how they feel in your hand. Go to places like kenRockwell.com and DPreview.com to compare them. Nikon and Canon have the largest market share and I personally think there is a very good reason they do. Not bashing other brands but photographers tend to be very very demanding folks and they then tend to be loyal to what has worked for them well and consistently. That is not a pavlovian response anymore than it is a pavlovian response in my work at the fire department when I trust the brands of turnout gear and airpacks that have worked for me time and time again. Sometimes even going beyond the published specs. People in ANY demanding profession gain loyalty and trust from thier experiences. And if the product did not perform it would not be favored for long.

Okay it's always concerning when somebody asks about a professional camera! You see as a professional you should know what type of equipment you need and then find a more affordable alternative. Furthermore a professional will be able to operate a camera to it's full potential. Now to a professional they would look for something like a Nikon D200, Canon 40D, Canon 1DmkII, Canon 5D or Canon 1Ds mkII, with the appropriate lens for the subject. If you're photographing landscapes you'll need 10-22mm lens for the D200 or 40D, and a 16-35/17-40mm lens for a 1D or a 5D. Portaits will need a 50mm or an 85mm on the 1D/5D and probably a 100 or 135mm lens. Wildlife demands longer lenses and the 1Ds and 5D may not have the speed of a 1D. You'll at least need a sigma 150-500 or Canon 100-400mm L, possibly a fast prime instead. Basically "technology" doesn't matter. Quality does. That's why a short zoom or fixed focal is better than an all-in-one which is useless. And an older prosumer or professional body brings you better control, and fewer gadgets and gizmos that get in your way, because all you need is Av/A Tv/S and manual modes.

Nikon D40, D40x, D60 or Canon XS, XTi or XSi.

the nikon d40, i love mine. i'm not a professional nor am i looking to become a professional, i just want nice pictures.
