Frage von Jendrik Hill:
Moin Leute,
I'm not sure if someone can help me here, but I have the following problem / question:
I bought after a very long time ago and read through and consider, among other things in this forum, the Canon 7D.
Since my father a Pentax K10 with some very nice lenses (at least the SLD's), I ordered at Amazon this adapter ring:
http://www.amazon.de/Halbautomatikadapter-PENTAX-Bajonett-Lens-Kameras/dp/B002U0O5H2/ref=pd_rhf_p_t_1
The Lenses I would like to use with the ring, both of Sigma.
(Http://www.amazon.de/Sigma-10-20mm-4-5-Lens-Pentax/dp/B000ELC666/ref=sr_1_1?ie=UTF8&s=ce-de&qid=1268480172&sr=1-1
and

Unfortunately, all this does not seem hinzuhauen really.
Although the ring fits perfectly onto lens, and then the two together perfectly synonymous 7D in the body, but unfortunately the whole picture for photos, such as video is extremely dark. So, almost black.
Aperture can clearly no longer pretend, maybe she is almost completely.
I'm still relatively new as far as photography, so I hope a bit that there is some kind of rookie mistakes that can can be resolved.
So, if anyone has an idea what can be done, someone has similar experience with such an adapter rings? Is it the fact that they only work with original Pentax lenses, and not with Sigma? (If this comic, yes, they actually fit perfectly), or the parts are just crap?
Thanks schonmal event that someone takes the theme.
Lg Jendrik Hill
Antwort von alibaba:
Aperture was supposed to be quite frank, if not strap the lens again s.The Pentax and they do it.
Self-adjusting you can do it s.der Canon but not (at least not useful for your projects), provided that a lens has no manual aperture ring, or is just built for Canon connections.
