Pentax unloads their new *ist DS, OptioSV, and OptioMX4 cameras on us

It's Pentax's turn this week to hit us with a bunch of new digital cameras in advance of the big Photokina trade show which starts in a couple of weeks. In no particular order:

Pentax *ist DS
The biggest news is the *ist DS, their new six megapixel digital SLR which is basically a budget version of their regular *ist D digital SLR and is meant to go head-to-head with Canon's EOS Digital Rebel.

Pentax OptioSV
The Pentax OptioSV (and apparently one must italicize the 'SV') is new ultracompact five megapixel model that uses the same sliding-style optical zoom lens first found in the Optio S, though they've bumped up it up from 3x to 5x (freaking finally, too, 3x was getting sorta tiresome).

Pentax OptioMX4

And rounding things out is Pentax's new OptioMX4, a new four megapixel version of their camcorder-style Optio MX which cops a bit of that retro Super 8 thing (you can record up to two hours of MPEG-4 video onto an SD card—though you'll have to be plugged in since the MX4's battery won't last that long) and has a 10x optical zoom lens, a pop-up flash, and a 1.8-inch LCD screen.
