Overall, its probably better to get a less expensive body and invest in lenses. That said, just starting out, the best overall - body and lens value is a kit, which contains the body and the kit lens together.
So with that, what to buy. Currently, the Kx is a very good value for a body. In time it will probably be replaced by the Kr which has some additional features, however these futures, you will probably be hard pressed to use, so by getting the Kx you will have everything you need. The Kx essentially has all of the most modern features. By going backwards to the Km/K2000, or K200D or K100D Super, you progressively loose technology upgrades and features. The price will go down but not that much. You also loose the warranty since the warranty has expired. With the Kx you get a 1 year warranty on the body and for an additional $20-$29 you can extended it for an additional 2 years. So my advice is the Kx (and with the release of the Kr, it will push the Kx price down possibly a bit lower).
Lenses - The kit lens. For the price, it is an exceptional value, and compared to Canon and Nikon - its a very good lens. Check out this link.....
Right now, you really do not know what you are going to be taking pictures of, so to go out and invest hundreds of dollars for a wide angle lens is not recommended. Buy the kit and it will work very well for you. It will also help you determine potentially what you may want to do next. There is also a 2 lens kit - the 18-55 lens and either the 50-200 lens or 55-300 lens. If you have and want to spend the additional money, the 55-300 is excellent (better than the 50-200). Between these two lenses - you should be set to really do anything.
If the 18-55 kit is too narrow, you can electronically stitch multiple images together as a panorama. For low light, you can bracket with three images and stack them in a HDR. There are a wide number of techniques that can be applied. With the basic kit, you have all the tools. Its just a matter of learning how and when to apply them to various situations.
Quote: okay, what is a better lens? 55-300mm ?
I really dont know even what to look at or for....I dont want to buy a body and crappy lens kit...
For a really fast prime you can get a k 50/f1.2 Special for a mere $2000
For wide angle you can spend $700 for a DA 12-24
For a really fine telephoto you can spend $1600 for a DA 60-250
For an excellent prime telephoto you can spend $1500 for a DA* 300mm
For a really specialized telephoto you can spend $9000 for a K 1200mm
I cherry picked specific lenses with high price points to try to make a point here. What I am trying to say, is that these are pretty specialized lenses with specific glass for specific purposes. You are not going to buy any of these unless you feel the need or have particular purposes in mind.
The kit lenses are not crappy lenses. They serve a purpose for a pretty large population of photographers. They work , work well and are affordable. They also let you discover where you want to take your interest in photography with out breaking the bank.
There are alternatives, also...
- The DA 16-45 for about $200 a kit alternative. But it is larger and heavier. It also extends out such that it leaves a potential shadow in the image if used with the pop up flash. The kit lens is much smaller and lighter. It fits into a coat pocket very nicely, as the 16-45 does not.
- There is the 16-50/f2.8 good lens for low light, but even larger and heavier. If you are not going to do a lot in low light, why go to the size, weight and expense.
I could go on, but I'll stop here....
The Kx kit you link to (Pentax K-x 12.4 MP Digital SLR with 2.7-inch LCD and 18-55mm f/3.5-5.6 AL and 55-300mm f/4-5.8 ED Lenses (Black)) with the 18-55 and 55-300 covers everything extremely well. The 55-300 lens is the basic zoom that most use and is a very good 300 zoom until you have the need to get a 300 prime for something like birding, etc.
