I, for one, would certainly have preferred a less noisy, lower pixel count with my otherwise excellent 8MP Pana FZ30. The higher MP figure was not the reason I upgraded from my earlier 5MP FZ20. It was the major overhauling of other features like the much faster startup, zoom ring, swivel LCD, relocation of the memory card slot, extended shutter speed range, higher resolution EVF and LCD, addition of RAW and 3:2 format, etc. etc. I'd even hoped that the change from 1/2.5" sensor to 1/1.8" would have offset the noise of a higher pixel density, but I was disappointed in this respect. What resolution do you use it at? I have several 8-, 10- and 12-megapixel compact and ultracompact cameras, but normally I set them all to 5 MP. I believe that helps a little, though it would probably be better if they were 5 MP natively. I sometimes set it to less than the max resolution but it doesn't seem to make that much of a difference regarding noise. At least not for pixel peeping. Towards the end of last year, I helped my nephew with a small commission to take pictures in various locations for a calendar. He used a DSLR but I also shot the same scenes with my FZ30. The night before we visited one location 150 km from my town, I set my camera to 1.2 MP (1280x960) and fogot to change it back and took several dozen shots at that setting. The people who did the final selection chose two of those 1.2 MP shots. The picture area on each page of the calendar is 10x16. Now that's 80 ppi and some pixelation is quite noticeable on straight slanting lines, but the rest of the picture came out much sharper than I expected. I've personally shown it to some two dozen people, including some who are taking up photography as a serious hobby. With the exception of one advanced amateur, none of them spotted the pixelation until I pointed it out. Admittedly most of them didn't possess an experienced critical eye, but it goes to show that a high pixel count is not essential for most people. |

I sometimes set it to less than the max resolution but it doesn't seem to make that much of a difference regarding noise. At least not for pixel peeping. I've never really made more than a casual comparison, but some of the high-resolution Coolpix models which offer ISO 3200 do so only at much lower resolutions like 5 MP. Since this is obviously for reasons of noise, I'm just assuming it must help a little at somewhat lower ISOs also. I will have to test this out more thoroughly.

I've tried my small cameras down to 3 MP a couple times and still could see no difference, but normally leave them at 5 anyway to stay on the safe side. But your experience at 1.2 MP is certainly an eye opener. |
