Shooting with Primes.

My blog has moved, see the new site at http://blog.badlightgoodlight.com

 

My main reason for buying a Pentax DSLR when I outgrew the previous camera was the value it represented. Compared with the equivalent Nikon or Canon models it was significantly cheaper. And, according to the many reviews I had read, there were a lot of little features that were useful that weren’t present in competing models.

One of the things that I have now learned is of significant value is the number of fixed focal length (prime) lenses that are available for Pentax SLRs. Lenses that were made decades ago for Pentax SLRs can still mount the new digital SLRs that are available now. The Pentax “K” mount is well known and popular and has been around for over 30 years. And lenses from the preceding M42 mount can be fitted with a simple adapter.

The point of this is that, more than any other manufacturer, there are hundreds of cheap, excellent lens available for the Pentax DSLR. Most of them prime lenses. Having such an abundant resource is a major selling point for a manufacturer that always seems to appeal to the hobbyist, rather than the pro.

Zooms have become the pervasive standard but t wasn’t that long ago when the lens you got with your SLR would have been the standard 50mm lens. The ubiquity of the zoom lens sees most DSLR kits being sold with what is now called the “kit zoom”; a lens covering a reasonable zoom range usually from a wide angle to a moderate telephoto. These tend to be made as cheaply as possibly and, though competent for what they are, are not considered “good” glass. These kit zooms tend to be fairly slow also, having a fairly narrow maximum aperture.
