ABSTRACT
|
The SMC Pentax lenses and other stuff database, SPLOSdb,
includes contemporary prices and information on SMC Pentax and selected
“third party” lenses for Pentax K-mount bodies, and other stuff including:
teleconverters; flash; macro accessories; special adapters; Pentax LX and
accessories; and, the *istD. The
prices are mostly for used equipment in excellent to mint condition, based on
over 2000 eBay sales during a three month period from to , and on list prices
at about 70 camera stores with online inventories. A total of 470 lenses and 100 other stuff
are itemized in SPLOSdb. Each item has
specific information on prices, dates the prices were observed, and the
number of sales on eBay over the three months. The database also includes a lens quality
rating system and a variety of physical properties such as minimum focus
distance, weight, size and other relevant properties. The database is distributed in .pdf format
for printing and viewing, and in ‘comma-delimited’ data files. This paper provides an overview of the
database, documents the categories and procedures used to define the
database, and discusses lens availability (i.e. common vs. rare), including
“Top-10” lists. |

I also want to thank Bojidar Dimitrov and Harold Merklinger (www.trenholm.org/hmmerk/) for

reliability discussed in SPLOS.pdf suggests that the accuracy is high, but
there certainly are errors and omissions - use this information at your own

which are camera shops with online inventories of used gear. These prices may not be the lowest
available, and the items may not be still available. I can’t guarantee that these Other
Suppliers are reliable, but I’ve personally had consistently good
results. I am not affiliated in any
