Sony offers a somewhat cheaper option for SLRs cameras with the A390. The CCD sensor with 14.2 megapixels of resolution. It comes with the Sony SteadyShot inside the camera for image stabilization. Aperture is set a basic range of f/3.5 to 5.6 with an optical zoom of 3 times. The ISO is pretty standard as well ranging from 100 to 3200. The LCD screen is 2.7 inches featuring Live View. It also has a Help Guide to aid newer SLR users. The camera takes JPEGs and RAW images. It’s slightly more than one pound at 17.5 ounces.

Digital Trends’ digital camera buying tips:
What about memory cards?
There is no universal memory card to fit all digital cameras – not yet, anyway. Based on internal politics, design considerations and financial reasons, individual camera manufacturers typically adopt a particular style of Flash Memory card for their cameras. Some manufacturers will even split their alliances – one type of memory card for professional-level cameras, and another type of memory card for consumer level cameras. When buying a new Flash Memory card, remember which camera you have and the type of card it requires. Some camera snobs (like your humble writer) will even selectively buy a digital camera based on the type of Flash Memory card they prefer to use!
The most common types of Flash Memory cards are:
Compact Flash, or CF – Roughly the size of a silver dollar (though not round), the CF card is one of the earliest types of Flash Memory cards and is most often used in professional or semi-pro digital cameras.
Secure Digital, or SD – Roughly the size of a postage stamp, the SD Card is available in a wide range of storage capacities. It’s inexpensive, durable and amazingly lightweight.
Memory Stick or Memory Stick Pro – About the size of a small stick of gum, the Memory Stick is meant for Sony Digital cameras.
XD-Picture, or XD Card – Typically found in Fuji and Olympus cameras, the XD Card is about 40% smaller than the SD card.
Don’t Buy Til You Try
One final bit of advice. Never, ever buy a camera purely on its specs or a few positive reviews. What looks good on paper, and what feels good to one person, isn’t necessarily going to be the perfect camera for you. Patronize shops that allow you to spend a lot of hands-on time with your prospective models. Cameras are extremely touchy-feely products, and the truth is that most of them include similar feature sets and take decent pictures. But they come in a wide variety of shapes and sizes, and you’ll be spending many hours with one of them in your hands. Long-term comfort is perhaps the most important factor of all.
What Should I look for in an LCD Display?
Camera manufacturers market display size quite prominently because it’s easy to visualize, but other factors also come into play. Resolution (usually measured in the number of pixels, like 461K) will determine how clear the display looks, and brightness will help determine whether it gets washed out when shooting outdoors. An optical viewfinder makes a great backup when shooting with a less-than-ideal LCD.
LCD screens are measured diagonally and 2.5 inches is a common size. We prefer even larger ones, up to 3 inches. If your eyesight is a bit challenged, definitely look for a larger LCD. Screens are measured in pixels, just like image size. Again, the more pixels, the better the image you’ll see on screen.
How many megapixels do I need?
In 2000, the answer to this question was “more is always better.” In 2010, the answer is more likely “if you have to ask, you have enough.” Even the cheapest cameras these days typically pack eight or more megapixels onto a sensor, which produces superb 4 x 6 prints, all the way up to 8 x 10, and sometimes more. The physical size and quality of the image sensor along with the corresponding optics play a much bigger role in image quality than megapixels alone, so don’t be fooled into thinking more megapixels will produce better photographs. Unless you’re planning to blow up shots to poster or billboard size, any modern camera has enough resolution.
When you’re researching different cameras, manufacturers will state the maximum file (or picture) size you can take. In the case of a 6 megapixel (MP) camera, it’s 2816 horizontal pixels x 2112 vertical pixels, with 7MP it’s 3072 x 2304 and so on. Simply multiply the numbers and you get the effective resolution of the imaging device. We suggest you avoid anything less than 6 or 7MP at this point unless you’re looking for an inexpensive camera for the kids.
Pros have access to 21-megapixel imagers in very expensive D-SLRs. You don’t have to go this route or spend that much money for great everyday photos. However, 6MP should be your minimum and if you plan on making very large prints, such as 13x19s, or you feel you’re going to experiment cropping photos with imaging software, consider 8- or more megapixels. There are no hard and fast rules since so much depends on your final end use
