I had a Canon Rebel 2000 SLR with 28-80mm lens. I want to buy a Nikon D80 DSLR and can I use the above lens if I just buy the body only?.
Is this a good fit and compatible.
Thanks for advice.

I have been using a Conon Powershot SX10is for some time
I have been looking at DSLR cameras
And I feel that the Canon EOS Rebel XSi is the best camera for me
Does anyone have any Hands on experience with it
Or camera suggestions

I would like to buy a DSLR camera for commercial use (in studio and outdoor) but i need a good recommendation. Which of the two is better? Any other model in mind? Please note: I only have about $800-$900 to spend on both camera body and at least 1 lens.

Everything about a digital SLR seems to work more quickly and responsively.That’s important when you want to make a grab shot on the spur of the moment, or expect the camera to take an action photo right now when you press the shutter release at the peak moment. Most point-and-shoot digital cameras are downright sluggardly compared to dSLRs when it comes to performance. You can find improved speed in three key areas, which I explain in the following sections.

Wake-up time
A non-SLR digicam that can be powered up and ready to snap its first photo in as little as two seconds is considered fast. Many take three to four seconds to emerge from their slumber. Worse, because they consume so much power,these cameras go into stand-by mode or shut off completely if you don’t take a picture for 30 to 60 seconds.

When you flip the power switch of a dSLR, the camera is usually ready to take the picture before you can move the viewfinder up to your eye. Some are ready to go in 0.2 of a second! Digital SLRs don’t need to go to sleep,either, because they consume so little power when not in active use. I’ve left dSLRs switched on for days at a time with little perceptible draining of the battery.Certainly, the autofocus and autoexposure mechanisms go on standby a few seconds after you move your finger from the shutter release, but they’re available again instantly with a quick tap on the button.

Shot-to-shot time
Conventional digital cameras have limits on how quickly you can take pictures in succession. Unless you’re using the motor-drive-like burst mode, one shot every second or two is about all you can expect. Even in burst mode,you’re lucky to get much more than about 1 frame per second for 5 to 11 shots, max.

Digital SLRs have large amounts of built-in memory that temporarily stores each photo you snap before the camera transfers it to your memory card at high speed. You can probably take pictures in single-shot mode as quickly as you can press the shutter release, and for at least eight to ten shots before a slight pause kicks in. With faster dSLRs and some quality level settings, you can often keep taking pictures for as long as your finger (or memory card) holds out.

A DSLR’s burst mode can capture 3 to 8 frames per second for 12 to 30 shots,depending on the speed of the camera and the quality level you’ve chosen;lower quality (higher compression) settings produce smaller images that can be written to the memory card faster. No point-and-shoot camera comes anywhere close to that level of performance.
