That's like complaining that the $3500 oven you just bought tops out at 500F...who the hell cares, lets apply a little logic here and a little less MTV teen mom drama

Hey Stephen, I really dig that second photo you posted!


Thanks! That was taken in my pitch-black bathroom. Lighting was from a parking garage a full block away -- about 150 yards. I showed her the screen, and she was amazed, because the photo has more detail than we could make out with our eyes. The metering worked well, too. It was shot at 1/25 at f/1.4, which I guess makes this the absolute minimum amount of light I could shoot the camera hand held.

As for the other photo, well there's been a real shortage of cat pictures from the new camera. ;)


My first shots with the camera were of my new kitten... To be honest the kitty makes more noise then the camera. http://www.timothycapp.com/blog/new-kitten/


Aww! What an adorable kitty.

mine has it too, even (ever so slightly) noticeable at 25600. It's too bad but hell, I wasn't ever gonna use H1 and H2 anyways. Seems they all have it.

I looked closely at some images that had a white wall and could see the pink in the lower RH corner even at ISO 12800.  I had noticed something not quite right with the right top and bottom corners, but now that I've looked, it is AMP glow.  Supposedly, that went away with the move to CMOS.  It was quite noticible with the CCD sensors and long exposures, but with ISO 12800 and a 1/40 sec exposure, I'm suprised to see it.
 
Here is a image.  Note, it was in my laundry room at night with lights off and the lighting was about -1 LV, and was darker on the right side due to light coming down a hall at right angles and the doorway shading a room that was almost totally dark anyway.
 
 
All my low light test images had a slight pink tinge in the lower RH corner, and to some extent in the upper RH corner.  The one below shows it the most.
 
I wonder if this will be a big problem for astronomers, I would certainly think so.
