hi All,
I would like some help please,
I have various lenses, (ie) Pentax Sigma & Canon,

the Pentax & Sigma have adaptors to attach to the Canon 1000D DSLR,

I would like to attach the above lenses to my Nikon D5100 DSLR,

can this be achieved with an adaptor?,
or do I use both camera's!!!,

thank you in advance for information,

regards,
Peter.
