I am an amateur photographer and this is my first step up to a more professional type of camera. This is my first DSLR. The things that grabbed me were how fast the autofocus works and how quickly this camera fires off pictures. I was also happy to discover it takes very good low light pictures using the kit 18-55 lens. Even when using ISOs near 400, there is almost no noise in the pictures. My Nikon P90 was uesless with an ISO higher than 200, so this is wonderful. I'm surprised that few of the reviews mention that Sony inputs "SONY DSC" into the caption metadata of EVERY SINGLE picture you take. This is extremely annoying since I have to remove it manually. The Sony software used to transfer the pics is also horrific. It does not allow you to use an automated folder structure other than the way it wants it, it also does not let you insert values into the metadata such as author or copyright information automatically when the pics are transferred. Nikon's software does all of this. Sony's software insists on using a folder structure based on mm-dd-yyyy which is uesless if you want your pics sorted chronologically after a year of taking pictures...they should be using yyyy-mm-dd. Again, if you want to use your own folder structure, you have to type it in every time you transfer the pics - it also doesn't separate them by date taken, it groups them all into the folder you are creating for that sync. I've resorted to using a third party app called PIE for transferring the pics to get around the folder structure problems. In addition, the battery is bulky and heavy and has a very short life. You'll want two or three spare batteries with this camera. I've read they don't hold their charge long in storage either, so charge them before heading out! A plus side to the batteries though is that they will display a percentage of how much juice is left - which is invaluable. Finally, the door for accessing the USB ports is extremely difficult to insert the USB cable into - it requires both hands and some fiddling for 20 seconds to line it up while holding the door back far enough. I was concerned enough that I would eventually drop the camera doing this that I gave up and bought an SD card reader to use instead. Since the clock syncs from the GPS signal (provided you can get one), there is no reason to connect it to the PC. The review may sound negative, but these are small issues and I decided against returning the camera simply because it is so brilliant at taking pictures. I do love it and can't wait to add more lenses. Sony just really needs let users have more control over how they want their data organized.

I was very excited about this camera. All the reviews made it sound like the second coming. Initial testing was promising. In my work I frequently deal with difficult light conditions that are beyond my control. This camera, and more particularly the non-traditional electronic viewfinder, suffered in these adverse conditions. The viewfinder was overwhelmed by bright light or glare, to the point where it was practically unmanageable. This would be a problem with other cameras as well, but in my experience is still manageable with a traditional prismatic viewfinder. I found the autofocus to be slow and not as solid as the AF on Nikon and Canon cameras that I have used. The camera didn't feel very solid. For my purposes this made me uncomfotable, as I use the camera in harsh conditions. On the plus side the camera was lightweight, and the images were solid. There were many great features that would be perfect for any user from casual to pro, so long as they can control the environment and won't subject the camera to the kind of beating that I would. I don't think that the camera should be discounted because of my review. I use cameras in very harsh and difficult conditions, which would tax any camera. Unfortunately, this camera was hobbled moreso than other cameras I have used.

Great Camera


Overall this is a great camera. It takes awesome pics and movies. Number one con: the included lens is cheaply made. Zooming in and out is not smooth at all; very rough. I also experienced this in the 55-200mm lens I ordered with it. Very aggravating as you would expect very smooth zooming for the price of this equipment. Second con: overheats when filming video and shuts down. While this is a "still" camera as opposed to a "video" camera, Sony should not have included an option that was flawed and would not operate properly to begin with. Very poor taste on Sony's part. Having said that, as a first DSLR, I'm happy with it.

almost perfect


i was a minolta owner so i bought this camera because it was compatible with my old lenses. it was also new technology that i would like to try out. the first problem i encountered was whenever i use it on full auto and the flash goes off, the shutter lagged so the images were coming out blurry. i fixed this problem by using the manual setting on shutter speed with flash. the problem with this is i can't get too close with my subjects otherwise they come out too bright. so by standing at least 10 ft away, my pics came out ok and sharp. my second problem was the video. the camera will shut off after 2 mins of recording due to over heating. this also happens when you're outside in the sun. you have to shield the camera from the sun while you're walking otherwise it will not turn on. i resolved this by removing the battery and fanning the camera while shielding it from the sun and it will turn on again. this would not be a good thing if you're outside taking pics for like an hr continously with the temp over 80 degrees farenheit cause this camera will shut down. i gave it 3 stars because of these 2 problems otherwise i would have given it 5 stars. i still love this camera because it focuses quickly and especially the panoramic and rapid fire shots that it can do. with my 18-250mm lens this camera can still hold its own. i've taken pics of insects from 5 ft away that i was able to magnify that made ppl say wow! i hope these problems are fixed with the next generation of alphas so i don't have to keep using the manual modes at night.


Eventual problem


I've had this camera for almost two years. Yesterday it just cut out on me. I've read that other users had this problem resulting in a costly repair. I love the camera but I was expecting more life out of it before I had any problems.


Camera of the Year 2010 - Love it!!!


I am not a professional, just like taking pictures. I take mostly landscape and wildlife photos. I also do alot of macro shots of flowers, bugs etc. I recently bought a second A55 Sony body. I wanted to be able to put another lens on it, so I wouldn't have to keep changing lens all the time. Once I was familiar with the camera I loved it. It is not heavy, and has alot of great features. If I had one complaint it would be, getting use to the small grip it has. I was use to the Sony A100 before I got the A55.I would reccommend but phasing out for newer models!


Great Package Deal


Purchased to upgrade to an APS-C sensor camera. Far preferred the DSLT approach to an outdated flipping mirror. Lens is a great all around zoom from wide angle to long telephoto. Battery life is a small challange, but bought a package of 2 spare batteries and a travel charger for a trip to Italy. Worked great. One in the camera, one spare, one charging. AF challanged at full zoom, but easy to address by focusing closer then zooming out, which AF always held. Used different settings to take the same pictures, had a very high success percentage with that approach.


easy to use and gets a pretty good photo


very fast focus and shutter. great all in one lens. auto focus is great for shooting video but camera will overheat very fast 2-3 mins, short clips is great. 10fs will not miss anything. Be sure to buy extra battery and car charger, cuz batter life sucks


good camera, very short battery life


This set is very good for traveling. However, 2 sony batteries are not enough for a day trip. VDO recording is interrupted due to overheating after 5 minutes shooting. Don't buy it if you want to shoot lots of VDOs.


Great New Technology


Have been using for wedding and vacation shooting since May 2011. Love the sweep panorama for doing a bridal party shot. My customers love it when I present an 8x24 group shot as a thank you for their wedding business. The 16mp is more than enough for the enlargements and handles well in all situations.


great camera


I find this camera very easy to use and the resulting pics are great. My only compaint is the on / off switch location and action makes it easy to turn on / off by mistake. Good battery life.


Deserving of "Camera of the Year"


Advance innovations with internal HDR, sweep panoramas, and many other leading features. Very reasonable price for all that it offers.
