Pentax Optio E90 Digital Camera Review
If you are looking for a cheap digital camera and gay on a budget so I may have found the digital camera is ideal for you. The camera is the camera Pentax Optio E90 digital, which is simply that it is affordable and easy to use, even for a beginner, 
but there are bad points.
The E90 features a 31mm wide-angle coverage and is capable of optical zoom up to 3 times, as you know is not as far as some other cameras on the market, but says there is also the option “Smart Zoom.” This Smart Zoom option allows you to expand up to 17 times the initial distance and without “losing the image quality” because, according to the manufacturer, but after trying this function was as I expected and is in fact a digital zoom.
If you do not know what the difference between digital and optical zoom, then I quickly explained the latter. Optical zoom is a real ability to magnify the subject without losing quality, digital zoom, the other simply crop the image and enlarges it, and this method reduces the image quality. Now you may think this sounds bad, though, that every digital camera has digital zoom.
