When photography was introduced to society, there were very few people who were interested in photography since the camera were rare and expensive. The pictures taken at that time were only black and white, however after few years the field developed so much that black and white photography became a category of the vast field of photography. Photography has been a famous and an old art which has flourished a lot through time. Camera became cheap and affordable, and several types of photography developed which was adopted as per the person’s own choice. Some went towards landscape photography, some were flourishing in the portrait and some were fan of black and white photography.
With the advancement and change in the equipment changed, not only the size of the cameras were modified but extensive work was done on the optics as well and several different size of lens were also developed. The camera manufacturing giants Canon, Nikon and Sony have been in the market for a fairly long time and have been selling the best equipment. There are several other companies which are also developing the equipment like lens at nominal prices which can be afforded by anyone even on a small budget. If you want to stay on a budget and purchase lenses as well, you might want to consider these companies to make the purchase. A major advantage of using lens from these companies is that you can use them on any camera body, be it canon Nikon or Sony. One of these companies is Sigma Imaging UK who has manufactured a lot of lens of various sizes. The company also faced hard times when they were unable to sell their Sigma 70 200 F 2.8 Pentax to maximum number of people in the market.
The lens was made specifically for Pentax which is another camera equipment selling company. The news of the discontinuation of the lens came when a Pentax user contacted Sigma sales operations supervisor to inquire about the lens availability in the market. The sales representative told that company discontinued the lens since it was not making enough sales in the market. However, there was one still available in the Amazon store. No wonder, the lens manufactured by the company are the best available in the market for anyone who wants to stay on a budget, however, if the company specifies it for use it gets harder to make the required sales.
If Sigma starts producing the lens which can be used on more than one equipment, it will be easier to make more sales. The same mounts from Canon and Nikon are making exceptional sales. Another reason for this huge difference would be perhaps that there are more Canon and Nikon users than there are Pentax users all over the world. As a result, the lens which was made especially to mount Pentax made least sales. Sigma has been making and selling lenses for various companies and hence is very famous in the community who are fond of buying lenses and increasing their collection.
