Update added Feb 2008. Still using it. Build quality lovely. Fires up and is ready to shoot very quickly. Konica lenses are well known for being nice. I bet you could get one of these on ebay for next to nothing. They're not well known or sought after but they ARE nice quality. They're actually heavier than many cameras because there's so much metal in the casing so if you want something light, don't get it! Original review follows .........
I bought one of these from Morgan Computer Company (see their web site for latest deals) for £140 in 2005. I use Morgan quite a bit.
I looked at jpg photos taken on my KD-510Z (5 megapixel) and a Casio Exilim Pro EX-P700 (7 megapixel .... with a Canon lense)bought in April 2006.
I found it hard to see any difference between the shots at extreme magnification so if you just want to shoot jpegs and a bit of video, this camera's great. If someone is selling one used, as long as it works OK, consider it. It's perfectly capable of satisfying most peoples' needs.
I bought the Casio because the battery charger for the KD-510Z failed and whilst I was getting a replacement, I thought I'd see what 7 megapixel digital photography was like.
If you want to sell pictures, most printers want tiff format pictures, not jpg. The KD-510Z only saves files in jpg format. The Casio saves in tiff format but the files, if shot at full 7 megapixel resolution, are 22mb+ in size and take a while to render so I use the Konica to shoot whilst the Casio is rendering tiff shots.
If you just want to photograph stuff for ebay sales and web sites, even a 2 megapixel camera will be easily good enough. Get one used for about £30! The resolution on computer screens is so dreadful, you can't see much difference above 1.3 megapixel resolution.
The ultimate camera in the Digital Revio range, the 5 megapixel KD-510Z features Konica's pace-setting Dual Slot memory technology. So you can use SD Memory Cards, MultiMedia cards and Memory Stick recording media. You can choose which to use for a particular shot, or swap images from one to the other - effectively doubling your memory options.
You'll have plenty to capture too. An exceptional start-up time of only 1.3 seconds, and a negligible pause between shots, means you'll rarely miss a photo opportunity - including up to 30 seconds of movie! The new Fixed Focus option also enables you to lock on at 1, 2 or 4 meters for an even faster shooting response.
The Macro mode gives you superlative close-ups. In this Mode you can switch between Wide-Angle, and get as close as 6cm, and Telephoto, getting as close as 50cm and so staying far enough away from small, sensitive subjects to avoid disturbing them.
The zoom performance is equally impressive. Combine the 3x optical zoom lens with the 3x digital zoom, and you have a 9x effective zoom performance.
The experienced photographer will find plenty to enjoy in the KD-510Z! Three different menus provide many tasty options. Or you can create your own customized mode, by locking the focus, exposure, exposure compensation and White Balance.
But despite its sophistication, the KD-510Z is very easy to use. Just three buttons control the main functions: Play, Display and Delete. A simple, four-way button lets you cycle through the various flash and shooting modes without going through the menu system. And to ensure that you see what you're shooting, the TFT color LCD monitor is adjustable for brightness and hue.
At a comfortably slim 29.5mm, the handsome, stainless steel case has a high quality look and feel. Naturally, you get all the regular features: Auto Flash, Flash ON or OFF, Night Portrait, Red-eye Reduction, Self-Timer. You can also add up to 30 seconds of voice to comment on your still shots, or as a voice memo.
There are some brilliant new features too. You can now control the flash volume; set up different levels of saturation, contrast, hue and sharpness of each shot - and reduce 'noise' and camera shake at slow shutter speeds.
But for real attention to detail, how about this: For digital camera users who miss the reassuring sounds of film cameras, Konica have even added the shutter click sound from the award-winning Hexar RF!
