The Sigma Collection

My Sigma lens collection:

 

 

 

From left to right:

85mm f/1.4 hsm
105mm f/2.8  macro
18-50mm f/2.8-4.5 hsm
28mm f/2.8 manual focus  (this one is for sale)

On the wish list:  35mm f/1.4 hsm Art  (new lens not yet available in the Netherlands.)

I prefer the Sigma lenses over the Pentax lenses because of their ratio price/ quality. Also the hsm type lenses by Pentax are known to have motor problems.
With a 35mm lens added, I cover a good range with prime lenses, which are usually better than zoom lenses.

Sigma 85mm f/1.4 portrait lens

The lens on the wishlist arrived just after Christmas and having played with it a lot, I can now handle it properly. The beauty of this lens is it's extreme sharpness, but very shallow depth of field at f/1.4, creating these creamy backgrounds.
At f/1.4 and iso values of 200-400 it is hardly necessary to use a flash indoors. The focussing is internal and happens by an HSM motor (hyper sonic motor) silently and very quickly. All this makes the lens ideal for children's photography. Some examples of our grand children:

At nearly 800 grams it is a very hefty piece of high quality glass:

Highly  recommended!
