Three months ago I purchased a new camera body. A Nikon D700. The D700 has a larger sensor chip than my older D70. This meant that the lenses I use on the D70 would crop the images in on the D700, so you don’t get the fill benefit from having the larger sensor.
I knew at the time I would be looking at having to purchase new lenses when I brought it, so I researched to see what was available, other than the Nikon brand. Nikon Lenses are top of the line, but unfortunately they are over the top in price too.
I knew I wanted a fast glass lens, f/1.4 or f/2.8. I love the idea of zoom lenses because its like having multiple lenses all in one. But the down side is you lose a few stops of light as you reach the zooms full capability. So I questioned myself often, should I go fixed focal length or zoom. Well times have differently changed and other lens manufacturers are producing really great stuff.
In the end I went will a Tamron SP24–70mm f/2.8 with vibration control. The great thing is, it’s 2.8 all the way out to 70mm. Awesome!!
The only down side was I had to go on a waiting list to get it. Two and half months it took before I could hold it in my hands. I picked up on the Friday just gone and I am stoked with it.
