Some old lens questions! :)

[Fotografer]

Hey everyone, I recently acquired two old lenses. One is a Cimko MT series 100-300mm, and the other is a Soligor 75-260mm. I have a Canon Rebel XS and I was wondering if I can use them with my camera and if so, what mounts would I need?</p>

<p>I appreciate any help I can get! Thanks <img src="http://thephotoforum.com/forum/images/smilies/icon_smile.gif" border="0" alt="" title="smile" smilieid="105" class="inlineimg" /></p>
