Originally posted by funkythiru I have tamron adaptall 2 lenses that work well with my camera but not K lenses (50mm/1.4). Is there a work around for them? Tried turning of SR/ put all the settings on manual didn't help. Focus length input & lens correction are grayed out. Any suggestions are welcome.
Are you using the Tamron Adapter with A contacts? If so, that’s why your Tamron Adaptall-2’s permit on-body aperture control.
To enable Green Button metering and manual FL input for IBIS when using manual lenses without A contacts you must first set Enable Aperture Ring to Enable in the Menu C >> 4 >> 26 (inexplicably, the default is Disable). Your K lenses will now ‘Work’ in M (manual) Mode with your K-1 (of course you’ll need to set the aperture on the lens). Lens corrections are only available for modern lenses with contacts that communicate with the camera.
This article in the Camera Help Central Forum will help you use manual lenses with your K-1.
Have fun! I use manual lenses constantly with Pentax DSLR’s. Click ‘thirty’s not enough’ in my signature. Under KX | MX | LX, those lenses (and many more) are all used on my K-1
