With all the emphasis on the backend of the business and especially the copyright issues that have become center stage we need to take a break from that part of the business.
Here is an article that I wrote back in 2009 about whether you need a dslr or not.
I get a lot of questions on different sites about the sensors size and what is better. I am going to approach it this way. I used a D300 with a DX sensor with a 1.52 crop factor and a D700 full size sensor camera. The link for the crop factor takes you to Ken Rockwell’s site on this and he has several photos up that show the differences.
A simple calculation for the Nikons for people who might be thinking about a camera, the first decision is really the most important. What are you going to shoot? If you are going to shoot long distance shots and do not have a very long lens here is what I did. I used the D300 for that purpose. I put a 400 Nikkor prime on the camera and it litterly became a 600mm lens instantly. Then I have a 1.4 extender for it so it in effect was the same as 850mm. Now there will be quality drop off with the 1.4 but not with the lens.
If you are going to shoot a lot of low light or close photos I recommend a full size sensor camera. There is a difference but for small photos there really is not much. A camera with the DX style sensors or Canons or Pentax and all the others will be fine. The difference really does not show up until you start enlarging the photos and files and you will definitely start seeing a difference.
Now with the D700 you can use the DX lenses if you choose to do so. I have heard you cannot do that with the Canons. That is something I will leave for you to do. No matter what kind of camera you are looking at or who the manufacturer is go get your hands on one first to see what you like and do not like about it. I love the grip on the Nikon cameras. Go to a camera shop or store and put the lenses on the camera and look at them. You can do that at a camera shop and most of them know about the average things concerning cameras. A retail store that has a camera section will not have the selection of cameras, lenses and the personnel in most cases to handle the questions you need to ask.
It is not really very hard to figure out. You need to make a decision on what you are going to shoot and how. As you grow you will probably become of the camera guys that carry more than one camera. It is really a must for the working photographer. I had
