Oddly enough this may be my favorite of the Limiteds. I say oddly because until now the Sigma 10-20 has been almost welded to my K10. I did not think of 70mm as a focal length that suited me but I was wrong. This paired with the DA 21 make a fantastic light prime kit. I know they are not the fastest of lenses but when coupled with the high iso capabilities of the K5iis it does not restrict my photography in any way.
To my mind there is a vast difference between a photograph and a snapshot.
A photograph is made, the photographer has a vision for the image in mind and sets about creating it. Waiting for the right light or weather conditions and often visiting the scene several times to get it just right.
A snapshot on the other hand is taken as the opportunity arises, often with minimal thought. It is what we do on holiday, when out with family, it aids us in remembering those moments long past.
Having said that, many snapshots are perfect, just like the postcard, whilst some photographs, despite the time and effort, look like a hurried snapshot.
I take mainly snapshots, but occasionally, I get a beautiful photograph.
