Originally posted by Raylon I am hoping someone can get some good shots of Jupiter with the K-5, just to see it's cropping power and IQ.
This is one of the first things i'm planning to do with my K-5 when i eventually buy it!
A few comments:
Firstly, is it true that the camera must be powered down to switch between grip and internal battery? If so, this won't help for long exposures!
Secondly, when you use the "long exposure NR" in-camera DFS, does it save the dark frame, or does it only put them together in-camera and give you a single output file? If so, wouldn't you be better off to take two exposures manually, so you can do the DFS in post-processing?
Finally, if you did want to make your own dark frame, would the lens cap really block out ALL the light? I know on some other cameras i've owned, the lens cap doesn't block out quite all the light. Multiply that by 100 minutes and you could get quite a spurious result!
