My new job has me pretty busy these days.  Combine that with a long commute and I have a pretty good excuse for not blogging much.  This morning, however, I wanted to test my new 50-200 lens for my Pentax K100D, so I stopped by the side of PCH and took a few shots.  I've strung them together below, along with a shot of my K100D (and of course, some gearhead stuff below that)

The Pentax K100D is a six megapixel DSLR with sensor based shake reduction, which means that the sensor actually moves in opposition to your body when you hold the camera. There are little motion sensors and little tiny motors (!) inside that wiggle it around.
It is pretty amazing stuff, probably gains at least a full stop, if not two.  What that means is better photos in low light.
Since I like available light photography, that seemed like a really good thing, especially considering that I can mount all of my film era manual focus K-mount pentax lenses on here and take advantage of the shake reduction; something which my Nikon DSLRs can't boast, since their shake reduction is built into the lenses.
That's why shortly after I gave my Dad my Pentax *istDS I picked this camera up at the Pasadena Camera Show for super cheap.  The two cameras are pretty closely related, but this one has the SR.
As it turns out, while the camera takes nice photos (I love the way Pentax renders colors) I had forgotten, after using my Nikons, how frikkin SLOW these older Pentaxes are.  I push the shutter button and feel like I can count "one potato, two potato, three" before the shutter actually goes.  I'm sure it isn't that long but damn, it is sluggish.  Bird in flight photos are a challenge.
The new lens is nice.  I have a Sigma 18-200 that I was real excited to get which just doesn't seem to autofocus quite right on this camera.  It can probably be adjusted but I suspect I'd pay more to do that than the lens cost.  Oh well.  The SMC Pentax is smaller, lighter, and focuses better.  It also renders colors better.  
Oh, yeah, it was cheaper too.
