help needed for my first slr camera?
I saw this camera on ebay.....
http://cgi.ebay.com/Nikon-D80-Digital-SLR-Camera-2-Lens-Kit-D-80-NEW-USA_W0QQitemZ160136748913QQihZ006QQcategoryZ147174QQrdZ1QQcmdZViewItem
it is coming with two lenses 18-55mm and 70-300mm. here im missnig 56-69mm range...is this a problem to be worried about or its not a big deal??? I dont have much understanding of the focal lengths..plz explain
Here is a mini-tutorial I made myself to compare focal lengths. This is NOT a lens test or a camera test! It is merely intended to show the difference between various focal lengths. The lens was the Nikon 18-200 VR lens, which is (by definition) an 11X lens, but that 11X does not tell you what the final image will look like. The camera was a Nikon D200 so there is a 1.5X "crop factor," "lens factor," or "focal length multiplier." There is further explanation on the image itself. It would help if you click on "All Sizes" above the image.
Your first lens would cover the first four pictures (18 - 24 - 35 - 50) and then skip to the next four (70 - 135 - 200 - 300). Of course, you already know that the zoom from18-to-55 is continuously variable and it does not skip from 18 to 24, etc. There's not a lot missing here, especially considering that you will have 10 MP to work with. We talk down about digital zoom all the time, but cropping and enlarging a little bit will easily allow you to bridge the gap from 55 to 70 when you edit your images.
I have dealt with Cameta a couple of times and found them to be very helpful. They WILL ask you if you want this or that extra thing, but I felt no pressure. They will probably suggest a UV filter or skylight filter for each lens and maybe an extra battery, so be sure that you are ready with comparable prices for these items. Their prices were fair when I bought from them. Also, since you actually finalize your deal on the telephone, you can add anything else you want. You MIGHT want to spring for the Nikon 70-300 VR lens, which is awesome. Its price is somewhat on the awesome side, though.
Here's my stock answer on that topic:
~~~~~~~~~~
Image Stabilization - Vibration Reduction
This technology is known as "image stabilization," "vibration reduction," "shake reduction," "optical stabilization," and "anti-shake" by the various manufacturers. It is "for real" and makes a visible difference most of the time. If you are using an average point and shoot camera without a monstrous zoom lens, you will see the difference in lower light situations where the camera will be using about 1/60th of a second or lower. If you are using a telephoto lens, the effect will be noticeable at roughly anything slower than the inverse of the focal length, which used to be our standard for deciding when you should use a tripod. If it's a 200 mm lens, you will see the benefit of "IS" or "VR" at speeds of 1/200 or slower. If it's a 500 mm lens, you will see the benefit of "IS" or "VR" at speeds of 1/500 or slower. Actually, you will notice a difference at slower speeds than this, but I'd say that this threshold is where it can be called a distinct advantage. Macro shooting benefits from "IS/VR" also, because any movement will be greatly magnified when you are working at extreme close range with high magnification. Also, I feel that "IS/VR" helps if you are using a point and shoot camera at arm's length as you compose in the LCD monitor. It is much harder to hold the camera still with your arms out in front of you. "VR/IS" would be helpful there, even with the shorter focal lengths.
Please understand that "VR" or "IS" (etc) will NOT stop motion in a moving subject. You need to use a high shutter speed and/or pan along with the subject in order to do that. VR is only to minimize the effects of camera movement to give you a better chance at getting a clear picture. It won't work miracles there, either. You have to at least TRY to hold still. You can't go down a bumpy road in speeding car and expect to get great shots.
This is a composite I made to demonstrate "vibration reduction," which is also called "image stabilization" and "shake reduction" by various camera and lens manufacturers. For the best results, you should click on "All Sizes" and then "Original" before making your comparisons. I tried to remain consistent for all three shots, but I guess as clouds move in and out, things varied by an f-stop or so. I do not think that depth of field is an issue in this test, though. I did not move my feet at all during the test, so the point of view is identical. All three images were made using 1/60th of a second, which I consider to be the low shutter speed for hand-holding a 60 mm lens. I made a reference shot with my 60 mm Nikon macro lens, since I know this to be a fairly sharp lens. I tried to hold as still as I could, but I did not use a tripod. I then made two more exposures with the Nikon 18-200 VR lens, set at 62 mm. I was trying to match the 60 mm lens, but I did it by just remembering some landmarks and zooming to match. As I used the VR lens, however, I did my best to actually "vibrate" the camera by inducing a tremor in my hands as if I was shivering in the cold. I took one photo with the help of VR and one without. It was extremely odd to look through the lens as I shook my hands.
Since the VR was working, even though I knew I was shaking the camera, the image appeared steady in the viewfinder! Okay, compare the shots for yourself. You won't see too much difference in the top two, but the effect of vibration reduction is very obvious when you see how the picture comes out when "VR" is turned off.
Nikon D200 - ISO 100 - Nikon 60 mm Macro and Nikon 18-200 VR with and without VR
I realized that the first VR demo (above) may not be a "real world" demo, as I was TRYING to shake during the exposure. Who does that? I was originally trying to answer a question for someone who had a problem with severe tremors, so I was trying to induce tremors in my own hands. Well, I should ask, "Who does that on purpose?"
So in this pair, I was trying to hold still for both shots. The white balance is different, as I am trying to learn about that, but I realized that the first shot I took had the "VR" turned off. Everything else is the same, because I didn't move and the shots were made less than 30 seconds apart. The exposures were the same for both shots. I did not do ANY post-processing at all, as that would defeat the purpose of the demo.
