Question about Sony Cyber-Shot DSC-F505V Digital Camera
I just got my new 505V today from Ecost.com. As I suspected it is an earlier version with serial number of 1128nnn which means it is a unit without the BOCS firmware fix. That's fine but what I want to know is how does your 505V perform in long shutter speed exposures? Do you have alot of hot pixels that show up? I did the hot pixel 8 second shutter speed test and my 505V looks horrible! KAzillions of hot pixels lit up all over the place. I even see a few hot pixels at 1 second shutter speed. Is this normal for the 505V CCD's? My S75 is really quiet with respect to long exposures, I hardly see any hot pixels at 8 seconds on the S75. 505V the whole dang screen is lit up with pixels! Please let me know if this is normal or a defect. Ulysses, Pondria, Ron and whoever knows their 505V well, HELP! Aside from this the camera is taking very decent focused pics in outdoors scenes. Indoors with flash of course I see what you all mean about that BOCS problem. Yuck! Aperture mode does fix the color balance but is limited in shutter speeds. And focus in low light is a terror. Oh well, as long as I can get sharp focused pics is what counts. But I am very concerned that I might have a defective CCD because it seems to be terribly immensely noisey on the 8 sec shutter speed in the dark with lens cap on test.

This is quite normal for the F505V and Cyber-shots of its generation. Starting with the S75, the Cyber-shots perform a bit better in terms of this type of noise reduction. But even these cameras display it at extended shutter speeds of over 1 second. Have a look at this typical 8-second crop from my own F505V. It was taken only moments ago. I had just fired the camera on. Room temperature tonight is about 72? F indoors (I need to open some windows!). The room is lit only by my monitor screen (black background on Phil's page with very little white or bright areas). The wall I'm aiming at is about 2.8 meters away, or at least that's what I set the manual focus for. So things are DIM! At the top, you see a crop of my original shot. It's full of several different types of noise brought into play by the long exposure of the sensor to light. Below, you see the results obtained by using the BlackFrame NR program (it's FREE). It can accomplish wonders with a shot such as these, though it is not perfect. It can save a lot of your shots, though. So all is not lost.

I don't know if it's considered "normal" or not, but my F505V does the same thing. The original in the msg above was only 2 seconds -- take a look at it and see how it compares to yours.
