Summary: I always wanted a camera that I could literally take and use anywhere. The Pentax W90 fits the bill very nicely. And indeed it does go everywhere with me. I reviewed it for ePHOTOzine and liked it so much that I bought one. If you want a tough camewra that you won't worry about to carry in your jacket pocket, one that will withstand the kids jumping on it, one that you can use in rain, sleet, snow, ice and even underwater, this is it.
Pros: Waterproof, crushproof, cold resistant and very compact. Buy the pentax Neoprene case to go with it - it hardly adds any bulk and gives good protection and fast access. It's a very liberating experience to have a carry-anywhere camera that can be used in all conditions. My picture of the inside of a working dishwasher has caused some interest, but eqyually well I've shot images from the street floor covered in water, driving rain, and when doing camera club talks pop ...
Cons: Infinity is not the best area of performance for the lens. It's much better at morer modest distances, but given its take-anywhere uses, this is probably not an unreasonable compromise. The flat glass cover for the lens also needs to be kept scrupulously clean, so in the very long term it gets more cleaning than camera lenses normally would. No scratches after 18 months or so, but eventually it may take its toll. This would be equally true of any waterproof camera.
Summary: I purchased the Pentax W90 mainly for it's Macro picture taking abilities. I love taking macro pictures! With the Microscope mode I am able to get within 1 inch of a subject and take an incredible picture. I also love taking pictures underwater in the ocean. This is where I ran in to problems with the Pentax W90.
Summary: I had this camera for about 2 years for using on my kayak. The picture quality is not as good as non-waterproof cameras, but if you take your time you can get some high quality shots. The macro mode produced some of the best results. I had used it several times in depths down to about 3 feet without a problem, but when I took it down to about 8 feet the seal succumbed, water leaked in, and that was it for the camera.
Pros: Lightweight, convenient for pictures while kayaking, canoeing or just hiking in the rain.The zoom works well and the macro mode works very well.
Cons: Difficulty controlling the focus spot, flash is useless on the water. Should only be used down to 2-3 feet and not for long periods of time.
Summary: We have not used the camera enough to write much. However the camera and kit was shipped quickly. When we opened the kit we found that the SD card would NOT format, we contacted the seller and was quickly given an RMA #, we returned the bad SD card and a new was was shipped immediately. We chose this camera due to the fact that all of our previous camera have died due to sand (from beach trips) or contact with the ground (i.e we dropped them).
Excerpt: I selected the Pentax WR90 over other cameras in the class for the following reasons (http://www.dpreview.com/reviews/Q209waterproofgroup/). 1- Slim design to fit in shirt and side leg pockets. 2- Pentax reputation for solid construction. (I used to repair cameras and found Pentax to have superior construction to Cannon.) 3- Recessed shutter and power button for ease of sliding in and out of pockets.
Excerpt: Solid, well built and easy to use. I take my W90 when shooting in wet and extreme weather conditions. The digital microscope mode is a nice feature. It activates three LED lights around the lens to produce a macro lighting effect and delivers clean, crisp 1920 x 1080 images. The IQ is acceptable but should not be compared to a P&S camera with a larger sensor.
Excerpt: Had the camera for a couple of days. What i like: Very solid feeling camera. Very rugged. Interface is very good. Half pressing the shutter will get you out any menu or playback mode into a shooting ready mode. I love the built in intervalometer mode. W90 does an excellent job with macro photography. Nice wide angle image quality. Tons of great features. Green shortcut button is very handy. A grat camera for those days where you don't know what you may run into.
Summary: Pues a mi cámara le pasa lo que a muchas otras, como he podido leer. Al encenderla, tira dos fotos y se queda totalmente bloqueada. Le he instalado el firmware que ya tenía (la misma versión), la he dejado una semana sin batería ni tarjeta... y nada. Alguien ha tenido alguna experiencia con el servicio técnico de España? Me van a dar un palo? Merece la pena arreglarla? Me parece una buena cámara. Gracias y saludos.
