i have many M42 lens .....
wanna to use adapter to use DSLR
pentax or canon ??
I know that ist DS support K mount and M42 mount (with adapter) and its focus screen plate is changable too. which is a very good design for manual focusing.
however, canon can use contax lens with adapter ,where pentax cannot.

any suggestion?
