That is such good quality for a shot taken at the equivalent of 6 minutes and 40 seconds at 400ASA!

First, a disclaimer: This is not meant to be a result of a comprehensive testing but rather a subjective account from a weekend of shooting photos in low light. So, during this weekend, I found an approximate level of light at which the AF on my new K5-IIs starts failing. I found that for the scene where the light requires the following settings: ISO 6400, f/1.8 and 1/25s - 1/15s, it is still capable of focusing. But half a stop to a stop below that, it starts failing (depending on the scene/subject) So, if I calculate it correctly, that combination gives me about 0 to -0.5 EV. Now, I haven't looked at how accurate/consistent the focusing was, although I seem to see some good photos. Here is an example of a photo taken at that EV with 77/1.8 (handheld): http://42graphy.org/misc/lvfx/_IR01266.jpg Igor -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
