Echoing the K1000 is also appropriate to the first of the new models, the K100D and its 
stablemate the K110D. Launched simultaneously both are 6-megapixel entry-level cameras aimed at newcomers to digital SLR photography. The only difference between the two models is that the K100D features Pentax’s newly developed moving sensor Shake Reduction system. The new models will replace the consumer-orientated cameras in the *ist range, including the DS2. Pentax’s other new camera, the 10-megapixel K10D due to go on sale this month, will replace the aging *ist D.
The pricing of the new models is highly competitive. The K100D is available online for around £399 complete with a lens, while the K110D is about £50 less. This compares favourably with other entry-level DSLRs, including the Nikon D40 (6MP, £399), Canon EOS 400D (10MP, £480) and the Olympus E-500 (9MP, £500). It’s worth noting that none of these competing cameras have shake reduction systems. The next cheapest DSLR to feature that technology is the Sony Alpha A100 at £490.
