Originally posted by tele_pathic I consider three important factors: 1. Pixels: K30 has 16mp while Canon has 18=Not that much of a difference, so it's a wash. 2. ISO performance: both can be expanded to 25,600=another wash. 3. shake reduction: as baro mentioned, you get shake reduction in the BODY of the K30, which means you can buy a pentax lens from 1980 and it will have shake reduction. Canon puts the shake reduction in the lenses, which has two effects: 1. makes the lenses more expensive; 2. makes the lenses more complicated with more things likely to break.
I looked at Canon stuff quickly and I think that's where you get the $200 difference the OP is seeing. The Canon is probably coming with the 55-250mm f4-5.6 zoom which is Image Stabilized. Their 18-55 is also stabilized. They offer packages with their 75-300mm f4-5.6 but it's not stabilized. I have steady hands but really like having SR, especially for a long telephoto. It extends the ability to use the lens in marginal conditions.
The weather sealing on the K-30 makes the camera feel like it's built twice as solid as the Canon. Even an unsealed K-r feels like a much more substantial unit than the SL1. The SR works against Pentax here a little, because the sensor unit moves and you can sometimes feel it move. The dials on the Canon really suck, and honestly I don't know why. They are the same design and materials as Pentax, probably the same lifespan, just terrible execution.
I never thought I would use weather sealing because it hardly rains here and I don't like being out in rain. But it gives you extra peace of mind when it just might rain, enough to bring the camera instead if leaving it at home.
