What mount is this? And does anyone know about it?

[tkruger]

I bought this lens fo $12. I need to know what mount it is so that I can get an adapter to fit it to my EOS Rebel T3. I understand the disadvantage of using the adapter but for the price to try a different lens it is worth it.

Also does anyone have any experience with this lense?

Pentax/M42 thread-mount by look of it, 'though it would be easier to say for sure if the images were sharper. The lens looks like a cheap, knock-off and probably not worth the price of an adapter.
