Genesis PLL-K1 - ?L?- type quick release plate for Pentax K-1 - Foto-Tip
Unfortunately it's only available in Europe, and shipping is around $30. Even so, it's still about half the price of the RRS or Kirk brand. I went ahead and ordered one. I'll update when I receive it.
Well i got ones of these last week, and so far so good.
The two lugs that stick up from the baseplate fit perfectly just below the LCD screen, and the L section fits snugly on the side. Together these ensure that once atached the K1 is not going to swivel on the arca mount if you turn your ball head so the camera is in the portrait position. I was having problems with movement in the portrait position with a heavy lens (D-FA 24-70) when using a simple arca plate design, so this appears to be well thought out.
This mount has the arca attachment on the L section too, so you could simply mount the camera directly in a portrait position. However as the L section is attached to the main plate by a single allen bolt, I am not convinced that resonance from the shutter would not be an issue if used this way. I will do some testing to find out. But as I said above, simply move the camera through 90 degrees using the ball-head of your tripod head and the K1 is kept firmly in place so this is not a real issue.
Battery and rubber terminal cover are accessible when attached, but the headphone and microphone covers are obscured. If you do limited video with the k1 , this won't be an issue.
Only downside is the plate attaches to the camera via an allen bolt, which means you need to keep the supplied key with you if you want to remove it while out shooting. I may try and see if I can fit a handle/coin-slot screw instead. Having said that i have found when hand holding the camera with the mount attached that it is less obtrusive than the standard size arca plate that came with my Gitzo tripod, so this shouldn't be a practical issue.
I ordered it from the Polish website on a Monday and it was delivered to me in the UK on the Friday by UPS.
I would recommend it.
