dslr camera zoom examples image
Jessy
I have a Canon Rebel camera with a 50 mm lens. Now, I want to take pictures from birds (as close as possible). If I would buy a 300 mm lens, how far away could a bird be so that it still could be zoomed in well?
I'm also wondering if I rather should buy a digital camera with a 30X Zoom for example because they are cheaper than a 300 mm lens and most have an Image Stabilizer (when shooting birds, one must be fast). What I'm not able to figure out is how many mm correspond to 1X for example or, can I not compare it this way?
Any help is much appreciated.
Answer
Depends how big the object is. A house sonme hundreds of feet away, an insect just a few feet.
Compared with a compact or bridge digital camera offering 30x (and starting around 28mm 'equivalent') a 300mm on crop-frame DSLR would bve around a 10x.
Comprisons can never be exact, and they very from model to model, but for ease of calculation for bridge or compact cameras take a starting point around 25mm to 28mm looking at full-frame DSLR (veery expensive) or 35mm Film SLR. A 'normal' lens on a crop-frame (low-to-mid-price) DSLR is around 30mm, and the kit lens of 18mm to 55mm is equivalent to 27mm to 82mm on full-frame.
Confused? Aren't we all! But certainly a 30x on a compact or bridge camera is much more powerful than a 300mm on a mid price DSLR. I recommend bridge rather than a slim compact because of the eye-level viewfinder. It is impossible to follow fast action (e.g. birds, sports) at long distance (big zoom) with a camera held at arm's length.

Is a point and shoot camera with an interchangeable lens as good as a DSLR?

I've been looking at point and shoot cameras with interchangeable lenses and was wandering if they will take as good of a picture with DSLR cameras? Also with the interchangeable point and shoot cameras, will they capture night shots (for example the sky)? Thanks in advance for your help
Edited: The camera I'm talking about is the Sony Alpha Nex-5 which has interchangeable lenses but it has a LCD screen of the picture you're about to take which DSLR's don't use.
Answer
Two big things that determine the image quality are the lens and size of the camera image sensor. Most compact cameras have much smaller image sensors than DSLR cameras though there are some new more compact cameras that have either 4/3" chips or APS-C size ships which are equivalent to most DSLRs. Interchangeable lenses allows you to install a quality lens catered directly to the type of shooting you need. Don't expect to buy a camera with a kit lens and expect great quality though. Often good lenses cost $1000+ for a decent one though prime lenses (lenses without a zoom) will offer great quality without the huge cost. Some 50mm f/1.8 lenses are available for $100 with great quality. More tips at: http://www.learningcameras.com
