View Full Version : DMK21F04 vs DMK21BF04 sensitivity

February 19, 2005, 20:57:52
I compare the sensitivties of of these 2 cameras. The 21F04 is 0.8lx at 1/30s, Gain 0dB, while the 21BF04 is 0.05 lx at 1/30s, Gain 20 dB. The gain was set really high for the 21BF04 to get the 0.05lx sensitivity.

How do their sensitivity actually compare under the same condition?

there is no objective way to compare cameras by their technical data. In general: the DMK 21BF04 is more sensitive and the SNR is better.
You should order a DMK 21BF04 for a free evaluation.

Hi Johannes,

Did you mean you have free evaluation unit available? I called last week. The sales guy in the US said they don't have that in stock right now.
