EasyShare DX7590: Kodak's Second Ultra-Zoom Digicam

Noise
The noise test consists of pictures of our studio shot taken at increasing ISO levels to show the effect on the image. The pictures were taken after resetting the camera to its factory default settings. The camera is then set to record with the highest quality option with Tungsten WB. Click on a 100% crop below to view the full-size image. All images are sRGB.| ISO 80 |  Click to enlarge. |
| ISO 100 |  Click to enlarge. |
| ISO 200 |  Click to enlarge. |
| ISO 400 |  Click to enlarge. |
As the crops above demonstrate, the DX7590 is able to produce acceptably low-noise images from ISO 80 through to ISO 200. The difference between ISO 200 and 400 is very striking. In the ISO 400 sample, there is a large loss of detail and clarity. In addition, discoloration begins to be a problem as red, green, and blue blobs are visible throughout the image.
| ISO 800 (1.8 MP) |

Although ISO 800 is only available at a resolution of 1.8 MP, we have included the above sample. At ISO 800, the image is saturated with noise and details are very soft. In short, it is nice to have the option to shoot at ISO 800, but don't expect good looking prints (even at 4"x6").

I could be wrong but isn't Kodak well known for making relatively low quality consumer and prosumer digital cameras while making really good top of the line digital cameras? By top of the line I mean REALLY top of the line.bpt8056 - Saturday, February 12, 2005 - link
I have been looking at both the Panasonic FZ20 and the Kodak DX7590. I just spoke with the VP of Digital and Film Imaging from Kodak the other day and she basically said that the DX7590 is considered a "prosumer" type of camera, but with simplicity in mind. There's the keyword: simplicity. I like to take good quality pictures and I know the FZ20 is the one to get. However, my wife does all the organizing and printing since she's a consultant from Creative Memories. She wants the process of organizing, printing, ordering, etc. as easy as possible which the Kodak cameras can help her with. Even after repeatedly showing her the procedure with our current camera, she still needs my help and I tend to be busy doing something else.Here's my take on the DX7590 and the FZ20:
FZ20:
Pros
+ High resolution, sharp details
+ Image stabilization
+ Hotshoe
+ TIFF Mode
+ High Zoom (12x)
+ Colors are good, but shows a hint of yellow
+ Chromatic aberration almost nonexistant
Cons
- Poor low-light/indoor shots (external flash can fix this)
- Noise level is nasty above ISO 100 (hence indoor pics won't look too sharp)
- Not quite as compact as DX7590
- Simplicity??
DX7590:
Pros
+ Kodak Color science
+ White balance (the best I've seen)
+ High Zoom (10x)
+ Noise level is pretty good
+ Can be configured as point-and-shoot
+ EasyShare (simplicity)
+ External flash can be used (need to have bracket)
Cons
- Aggressive compression
- Soft details (grass looks muddy)
- Chromatic aberration is apparent
- No image stalization
- No TIFF or RAW mode
The FZ20 will give better results with pictures, but the DX7590 provides a better ease of use.

Don't forget Panasonic FZ3: small size and 12x zoom with image stabilizer at ~$320.BPB - Friday, February 11, 2005 - link
The Panasonic reviews are impressive. Interesting that it too has slow frame rates for video with sound.One big plus, to my way of thinking, is the Kodak printer dock. We have one and love it, even though the price per print isn't that cheap. Still, it's a lot easier than heading out to a store or emailing to an eshop.

#5 - If you are running the native and highest 1600x1200 resulution on your Dell, you are still compressing your image from 2576x1716 to 1600x1200 when you view it. Your Dell screen is less than 2 megapixels, so filling the screen is not any great indication of the quality of a 5 megapixel image. You would likely be better judging quality by viewing actual pixels on screen and scrolling around the image.ironman67 - Friday, February 11, 2005 - link
I've had a Lumix DMC-FZ20 for over a month--Fantastic!!! Pictures taken at medium quality at sharp and detailed even when I enlarge them to fill my 20 in. Dell LCD.BPB - Friday, February 11, 2005 - link
As a DX6490 owner, I think I'd be very happy with this camera. We may sell the 6490 and upgrade. Not being a bigtime photographer, the problems they mention here wouldn't matter much. The few annoyances the 6490 has for us seemed to have been bettered in this model. So, as an average camera schmuck, I think this would be a good camera.But I am going to look into the Lumix mentioned above.

I bought my mom the DX6490 (the 4MP version) for Christmas 2003, and it's a GREAT digicam. I'm thinking of getting this one for myself.The Doc is a nice feature for technophobes like my mother, with simple instructions like "Put the camera on the doc, and press the big button". That's one reason I reccomend Kodak cameras to less tech savy people. combined with Picasa2, they're absolutely perfect for those types of people. I get a lot less "support calls" for the Kodaks than other digicams.
