The Asahi Takumar 135mm f3.5 tested with a Canon 5D with an m42 adapter. <br />Amazing bookah at 3.5. Focus ring is smooth and the image appears nice and sharp. The lens does add a yellowish tint (though these clips were altered in Color).<br /><br />The GOOD:<br />Amazing Unique Bookah<br />Vivid Colors<br /><br />The BAD:<br />Tough to maintain focus<br />No Auto Focus<br /><br />http://www.PentaxForums.com/<br />http://HD-DSLRvideo.blogspot.com/
