I looked up the D50 on Amazon, and they offer the body only as well as three kits: body + 18-55mm lens, body + 28-80 mm lens, and body + 18-55mm and 55-200mm lenses. Are all three of these kits widely available in stores? I have usually seen it with just the 18-55mm. It seems like the 28-80mm lens would be the most versatile for a beginner, is that correct? Any suggestions? Thank you.

The 28-80 is a kit lens from film SLR's and is just put as a "kit" with the D50 to get rid of old stock, I guess.
50mm is considered the "standard" focal lenght for 35mm film SLR's. Longer goes towards tele, shorter goes towards wide angle. 80mm is a nice length for portraits (its slight tele shortening gives a flattering effect) and 28mm is a moderate wide angle.

Because the sensor of Nikon DSLR's is 1.5x smaller than 35mm film, you need to multiply focal lengths with a 1.5x crop factor to understand the field of view you will get in relation to a 35mm full frame camera.

28mm will become 42mm, 80 will become 120mm.... not really a "versatile lens".

That is why the kit lens for the D50 is 18-55mm... it gives a focal range comparable to the 28-80mm 35mm film kit lens.
18 becomes 27, 55 becomes 82.5. So, you do get a moderate wide angle at 18mm with a D50.

The 55-200 is designed to be a cheap companion to the 18-55. The 18-55 is actually quite a good lens, in areas better than the 18-70 kit lens from the D70s (less vignetting, more contrasty, less distortion (but the 18-70 has better build quality)). But the 55-200 is disappointing... at 55mm it is an excellent lens, but towards 200mm its gets soft and all contrast falls away.

So, depending on what lens/focal range wishes you have, it is best to choose the 18-55mm kit, or to choose the D50 body only, and to get lenses you actually want.

The Body + 18-55 is a standard Nikon offering so is the Body + 18-55 + 55-200.
Both kits seem to be widely available in Retailers (even here in Australia).

I have seen posts about Retailers offering the Body + 28-80 but I'm not sure whether it's a Nikon offering or just something that retailers are doing by putting a Body only box with a lens box.

Thanks! That helped a lot. And so quick, too! :D

Is this the case with all lenses? None of them will have the field of view they "say" they do? Or how can I tell which ones do and which ones don't?

The crop factor is a function of the digital camera not any particular lens.
You need to aaply the crop to every lens ie. a "50mm" lens is effectively a 75mm on a DSLR, a "18-55" is effectively 27-83, a "70-300" is effectively 105 - 450, etc.

That helps a lot. So as I am looking at lenses, I will remember that 75 mm is "standard" -- roughly the same as the human eye. And a lens that has a range on both sides of 75 mm would be the most versatile. Right? Thanks!

Wait ... why is that not a versatile lens? I thought (as I posted just a second ago) that having range on both sides of 75 mm (50 in 35mm) would be versatile. 42-120 sounds good to me? What makes for a versatile lens? I want to be able to do some zooming, some close-up. But I'm just a beginner.

You are round the wrong way.
A 50mm lens in a SLR is effectively a 75mm on a DSLR.
If you want a lens that does the same job as a 50mm would on a SLR then you need a 33mm lens for a DSLR.
Any given lens is LONGER when used on a DSLR than when the same lens is used on a traditional film SLR.
The kit 18-55 (effectively 27-83 if you could use that lens on a film SLR) would be a good place to start.

Ohh-kay. *math is not my strong suit* So a lens with range on both sides of 33 mm would be most versatile for me and my D50 (when I get it. :D) And since the kit lens is 18-55, that's just about right. Whew! Thanks so much.

Well, my interpretation of a versatile lens is that it gives both portrait photography and wide angle photography in one. If you mean with versatile a lens that offers a big tele range, then you should be looking at other lenses...

A more versatile lens that does not cost very much is the Sigma 18-125mm lens (giving you a 27-187mm), but you could also thing of getting the Nikon D50 with 18-55 kit lens and a Sigma 70-300 APO DG lens, which will give you more tele reach for an affordable price (while keeping the kit lens for wide angle and portrait views).

Thanks for all of your help. Being so new to photography, I don't really know what I mean by a "versatile" lens ... basically, I want to be able to do some close-up and some zooming work. I know the kit lens won't be excellent for either one, but it sounds like it's a good place to start. Then maybe get the Sigma 70-300 later, after my credit card cools down :p
