Do your resurch this web site compars cameras.
have a look and see.
I sugest you get the best camera that you can aford with the features that you think you will use the most. Remember most cameras only come with a stock len you will have to buy macro and telephoto lens along with filter lens. I had found a site not long ago that did comparisomes side by side and I mean everything including the # of shutter action you should exspect. on all types of camers and lens I could not find it tonight but I will look again It my have been in a magizine.
