    The switch is turned 90 degrees, and guessing from the online sigma photos where the switch is right under the window (and therefore at the top of the lens for others)
    on mine it's down to the bottom side

    (I already have a gigapan 100, I use it for fun arty panoramas, but I couldn't make the workflow efficient enough for me at work, shot time + stitch time + weak battery life was too much for the volume I want to do, and I don't need that level of ginourmus- that's why I was going for the 4 & done simplicity)
    I guess it is like the Nikon Mount. Can you take a shot like this one

    So that I can do a detailed comparison.

    HI Mark,

    Thx a lot for the images. Just get the sigma 4.5mm Nikon Mount for your Pentax. I will offer you full refund including shipping if it does not fit.

    It fits fine, snapped right into place against the raised edge.
    I can even see through the range window (which I did not expect)

    I haven't found my 'sweet spot' yet- alignment via panoweaver isn't right yet
    but I've only been able to attempt 4 sets of shots at different settings since receiving it
    (my work is about to start up for the season, I've been busy) but the best result unfortunately grabs the edge of the r-1 receiving plate making a perfect little square going around.

    Hi Mark,

    Thanks for the confirmation. good to know it does fit.
    to reduce the square foot print of QR clamp on R1, you can try reversing it. The clamp is asymmetric. reverse it so that the shorter portion is at the front. Use the hex key to loosen the screws on top of the clamp. Be careful of losing the brass safety pin and the spring inside.
