they will work with a 1.5 mag factor. ie your 28-70 will give a feild of veiw equall to approx 40-105 mm and your tokina 120-600 mm.
you may find yourself wanting to get the kit lens with your k10d to cover the wide angle range.

As long as it isn't three times as large as a typical post.....as in 2400x2400 pixels..... there is a trade off that levels the playing feild, one larger image with more detial vs three smaller images with less detial........
there's three different images in this one:

I'm gonna have to agree with George's earlier post...somwhere in iether of the two manuals, there is an answer....but we've ruled out defective card, defective frame and defective camera.
It's a compatibility/setting issue on either the camera or the photo frame.....
either the frame or the camera should have a setting you can adjust.....
trial and error and manuals are your only options....
other than keeping a card for the frame and having to transfer through the laptop every time.

my bet is the way the camera writes to the memory card, creates a folder for the viewing thumbnails and a seperate folder for the hi res images, and your photoframe is reading the low res folder only. it may even be the file structure or file names that's doing it.

take the images from the camera, to the laptop, then format the memory card with the laptop and copy the images back to the card. then see if the images look good on the photoframe.

it's probably playing the thumbnails, not the large images.

WTF???!!!

Reminds me of my childhood Christmas's...
