Telephoto lens

You cannot get as close to an object but you can get a very sharp image and a good blurred background adding interest to the image. Telephoto lenses are a bit more complicated. They have fixed length telephoto, zoom telephoto and professional series and regular lenses. I t really depends on what you are photographing that will dictate what type of lens you use and then of course money. A good regular zoom telephoto can run 500.00 + a 600mm fixed length professional series lens can run 7500.00+. This is for a 35mm camera. Of course if you are photographing birds in the wild, say small songbirds and you can afford a 600mm lens you will see a large and substantial difference in the quality between that and a 10 – 300mm regular zoom telephoto.
Once we go through some of the preliminary of the lenses then I will move onto how I took some of the photographs that you have seen on these blog post and on Nature Photography with a Purpose.

Conventional automatic focusing is done by moving either the entire lens system or just moving the front lens group. Hypermetropia

Hi Hypermetropia,
You are right. With the image I was trying to describe that effect. That is I was a bit further away then I would be if I had a macro. Also with the focus subject, it depends on the distance of the flowers in front and back of the main focus flower and how the blur will be. This adds a different element and artistic view of the photograph.
If I had used a regular 35mm lense this image would have looked very different.
