Hello gurus, I hope you can help me with a problem. Thanking you in advance!
I have a new K3 but some of my lenses arent working with it - the lenses that worked with my Kr.
In particular this lens is not working with the K-3: Sigma 18-125 F3.5-5.6 DC
A Pentax legacy lens doesnt work with it either: 50mm f1.7 SMC
Two other lenses also don't work:
An MF legacy ricoh rikonon lens
Another sigma MF lens
All of the above lenses work with my Kr.
All the aperture blades are working on the lenses & they all work with my Kr.
TESTING:
Set to M (manual)
MF lenses set to MF and aperture ring enabled
The result i get with the lenses that arent working is that no matter what aperture i set the exposure comes out the same.
Can you tell me why the lenses don't work on the K3 or how I could fix the problem?
Thank you!
