Sony Alpha SLT-A57K 16.1 MP Exmor APS HD CMOS Sensor DSLR with Translucent Mirror Technology, 3D Sweep Panorama and 18-55mm Zoom Lens

So liking the a57. I read reviews at length, for weeks, before settling on this model and I am so glad both to have made an informed choice and to have that choice proven in reality now that I've had the camera in hand and used it. The a57 is more complicated than a DSLR, with dependent inter-relationships across both common and novel functions and priorities. The a57 is not point & shoot; it's more like a lump of clay, that sees you as a lump of clay as well. If you know what you want from both a visual and a technical perspective and have the right lens for it, the a57 will get you there. If you have blind spots now, but want to learn to be a competent all-around amateur DSLR photographer, then this is your gateway drug. The a57 doubles as an excellent digital photography tutor, and will help you build understanding and skills every step of the way. The Sony way, that is. If you just want a pro-looking DSLR with a big black lens that makes impressive clicky noises on the 50 yd line, but is otherwise a simple point-and-shoot, then look elsewhere. In its' various Auto modes the a57 can serve as the King Tiger tank of point-and-shoot; the issue is that a novice to the camera could select settings or lenses that counter this functionality and then become lost, with mixed end results. The user may not realize dependencies to a setting in some other menu area (where was that, the Menu menu or the Function menu, or wait was I in Movie Mode, or did I hold down the ISO button then roll the knob...?), and one could spend time puzzling over why it's not doing now what it did before, when you're in some manual mode rather than auto. If you haven't done the reading, which I will mention further on, you may find it hard to keep the dependencies straight. When in doubt, reinitialize! In the more manual modes, there are several of these newly arrived Sony tech settings that can throw you off and I'm not talking fstop vs shutter speed, the rabbit hole goes way deeper on this camera. Sony has introduced new concepts and approaches to a pro DSLR while also attempting to maintain "point & shoot ease" and though this camera succeeds at the former two it is initially at least, a fascinating & robust failure at the latter. Works fine though, if one devotes the head space to learning some new feature concepts. Do that, think through your shots and vids first, and this camera will reward you handsomely for the effort. Rolling the dice WITHOUT first reading the manual (THIS manual btw, thanks to TCav of Steve's Digicams forum for the link: [...oops please do a search]), will probably result in some mediocre shots at first.Note that the a57 can take (and I'm doing it) the quality Minolta a mount AF lenses that you can find cheap on Ebay. It amuses, considering that many reviews argue that there aren't sufficient lenses for this camera, when there dozens of pages full of reasonably priced Minoltas, Tamrons etc. that will work with this lens. I got myself a Tamron 90x300, a Minolta 50mm f1.7 prime and an Abeline 500mm for less than $230 including shipping! So if you like to play around and really test to see what works for you there is an abundance of lenses available, from fish-eye to macro to 4000mm tele zooms on Ebay. Keep in mind though, that there's an approximately 1.4X mag factor on these lenses which is going to change your field of view compared to what you might normally expect - a Minolta 50mm f1.7 lens perfect for tight interiors, is gonna be a 70mm lens and you may notice that difference. You also have to remember that the 300mm you are reading on the lens is actually 714mm, etc. A labelmaker would resolve that issue. I got my a57 with the 18x55mm kit lens and I have no complaints thus far. The kit lens is solid but not overly heavy. If it's plastic like the body is, as some reviews have written, then it is a metal-like plastic. It seems more like aluminum to me, but there is little relevance in plastic vs. metal at this level of product engineering. Consider that this is an SLT rather than a true DSLR, for instance. Since there is no mirror-flipping going on for every focus instance, that vibration common to DSLR's is not existent in this camera. This means that the camera does not have to wait around for itself until the mirror has stopped vibrating, before it can image again. And this means, faster finger press to shutter releases, and continuous photo bursts in shorter timeframes. So, even if metal were a more stable material for a body (which, at this level of engineering, I rather doubt), that is hardly helpful when you still have to wait around while your mirror vibrations dissipate through that metal body before you can image again. To say nothing of being able to autofocus real-time continuously while taking 1920X1080P 60P video!The 1.4 firmware update is out, you would want to snag that, just because.The camera has a cool target reticule, that indicates pitch and roll alignment of the camera body, like a built-in level. Since the display can be folded out and around, this does help to maintain a level shot in these awkward positions.One cool, new-to-me feature, is what Sony calls Peaking Level for manual focus. When set to manual focus and with 3 settings, low medium & high, the Live Display (which generally shows the final picture live all of the time, essential) shows a fine pixelated wash across the image, in a plane that IS the actual focal plane of the lens cutting through the 3-dimensional image space, so you move the focus out and this plane of (I choose white) pixelation occurs across the image telling you precisely where the focal plane is hitting! You don't even have to see the fine elements of what you are shooting. Fantastic! For instance, one of my cats is black, so he is a black blob in the viewfinder or display. But with Peaking Level, I can clearly see delineation as to where his nose is, then whiskers, then the surface of his eyeballs, as the Peaking Level effect illustrates the focal plane's position as it moves in - and I take the shot when the white noise is where I want the focus to be. You do need 2 hands, to use this feature. And to be clear, this is not one of the "3-D panorama" features of the camera. I have not used the 3-D panorama or panorama features as yet.The a57 feels solid and heavy, as one would expect. I picked up a Nikon D6 the other day and it felt like a toy in comparison to the a57. Even my Casio EX-FH20 Super Zoom felt more solid than the D6 actually, not that I have anything against Nikon. Just saying, build quality should matter. The image that you take is more important than the image that you want to project as a "serious photographer," ha ha...The a57 sports myriad display symbols within multiple configuration menus, all of which you will have to learn in order to interface with it. This camera takes on the bushel of both tool and tutor, and its' abundance of menus does reflect that. Now that the world has not ended, any familiarity with Mayan hieroglyphic script will find new application as one works through understanding the functionality of this camera. Hey I did it, and learned a lot in the process. The tutorial aspect of the camera is somewhat separated from the controls aspect, so you don't have to constantly work through menus full of advice to get where you need to be. It is there if and when you need it. I found it helpful mostly for understanding the new concepts and terminology that Sony labs have come up with, in advancing the field of digital photography. I wouldn't hold my breath waiting for other companies to figure it out, when many are after all, buying sensors made by Sony to use in their own "cutting edge" cameras.Take it slow with the a57; the amount of information needing assimilation, will overwhelm anyone so take it task by task, in stages. I find connecting the HDMI out to my flat screen TV, lessens the tedium of the small display. I learned the camera (and still do) in 'study sessions' on the big flat screen. You see the complete display on the flat screen monitor, in both movie and pic mode. I'm experiencing macular degeneration for the first time (joy) due to age, and have recently begun using readers, so I rely on the diopter-adjusted viewfinder when taking stills, but for me studying menu settings of a digital camera for long periods, through the viewfinder, is an added strain that I do not want. It certainly works, but learning on the flat screen is much easier. You can toggle back & forth between your camera's HDMI in to the TV, and the .pdf a57 manual on your computer's input to the TV for instance, for learning ease. You can even go picture-in-picture.The autofocus system is fast, and great for video, particularly when you learn all of the autofocus modes and settings and creatively apply that understanding to your project. You can deliberately pace & plan your pans, to take advantage of this amazingly snappy autofocus capability. You may have read reviews that complain of the a57's limited manual controls over video when in autofocus - there is a little switch on the lens that says AF MF. Just set it to MF and focus manually, if you find yourself trying to use AF in an MF environment. If you aren't good at manual focus for pictures, use the Peaking feature. You will get better.There is even an unlabeled 'mystery button' on the camera. Now, any cold-blooded, dyed-in-the-wool amateur photographer would have immediately asked what the little button on the bottom of the a57 is for. I did, and it is the Preview button. If you push this near-unnoticeable button while in Auto Aperture, it will display for you the full depth of field effect of the shot, with the blurred fore-and background to either side of the focal plane. I am still testing this, as I can already clearly see depth of field in the WYSIWYG display/viewfinder.There are lots of APS-C sensors out there. The a57's APS-C sensor has comparatively good sized individual sensors, which is just one small part of all of the tech working together in the a57 to result in great video and picture quality. I know of no camera that works harder to get at what you want, if you know what it is that you want to get to in the first place, that is...The a57 records in AVCHD 60P, and is about the only DSLR under a grand that can do that, apart from the other Sony's, like the a65, a77 & a99. And that is what I needed, and it works. I can rewrap and convert footage on my Macs w/no issue between Free MTS M2TS Converter, JES Deinterlacer & MPEG Streamclip, and get 50% frame rate reduction that way for good HD slow motion, though I can't watch the AVCHD natively on my Macs (no need to yet). I can watch a57 footage via VLC player, but with a stream rate of 26Mbps, my Macs are better at editing than AVCHD playback anyhow, and what I do is use Toast 11 with the Blu Ray plugin to burn to Blu Ray disc if I'm not going to a lesser stream rate. Toast 11 is stable and provides the option of crude Blu Ray menus if you need that for weddings and such, and it's not expensive. The a57 has a separate button for recording video, not the shutter button; it took me all of 2 tries to set that difference to memory. You can disable the button, if your fingers are in a constant and unknowledgeable flail. I've never had a problem with it and even if I did, I wouldn't call that a problem as I have actual real problems in life to deal with. As with any camera new to you, there will be subtle and not-so-much subtle differences.Low light performance is all there with the kit lens. I find that the kit lens has a little stiction in the zoom but there is an element of my own inexperience involved here; hand muscle memory for stylish manual video zooms is something that has to be worked at anyhow.The a57 is only dust sealed, not weather so one should have a rain sleeve in their bag just in case.Battery life is long with the camera. Though it doesn't have GPS, I happen to have a Pentax WG-2 GPS for that. The Sony a65 at about $200 more than the a57, has GPS that I believe tags every video key frame with GPS data, if you need that. Double-check first before picking one up, it's just what I read. If I thought the a65 were a better camera overall, I would have bought one of them, but 24mp is a lot of video color data and though I wasn't certain it would be a factor in post processing I'm happy to have avoided that possibility. The a77 though weather sealed, is a lot of money and some users have noted sloppy knobs after significant use cycles; I can't attest to that but since I can't afford an a77 anyhow, I am indifferent to the issue.I can't comment on the on-board stereo audio recording capability, haven't needed it yet - but there is a stereo mini plug jack to connect an external microphone. I haven't been paying ANY attention to sound yet and that bit me in the boo boo recently as I learned from a colleague that a slow motion test of mine had slowed audio, that then cut out halfway through the video leaving silence for the remainder! Of course I had expected the audio would be played back at 1/2 speed, but I did not anticipate the truncation. When I get to the point of working with on-board camera audio in a project, I hope to remember to post my impressions of it here.The a57 is dust sealed however the sensor cleaning is accomplished through vibration cycles. I find that a bit unnerving and so I try to carefully prep when swapping out lenses; if swapping where you can ground out static electricity with a wrist ground strap that might be worth the bother; setting down a lens on a surface with a pre-existing static charge and dust, could cause a static attraction with dust lifted to the lens that could then become pulled in to the camera sensor if the camera were differently charged than the lens, and we don't want that. The sensor can do 16X9 or 4X3; in 16X9 you are not using the whole sensor, but since full HD is only 2.1Mp or so anyhow the subset of this 16MP sensor is sufficient. I have been running in 16X9 but then I mostly shoot video with it. The low light capability, short focal length of the 18X55 lens, huge sensor (comparative to camcorder) and enormous fun of playing with depth of field in video, and smooth realtime video autofocus make the a57 just hugely fun to plan and shoot video with, and there is a uniqueness to DSLR video shot with this feature set. It's a frontier camera, but sans weather sealing, not perhaps a camera FOR the frontier.About the viewfinder, it is a full WYSIWYG so you don't have to push down the button halfway to know what you're dealing with, in most instances. And you don't have to look from the viewfinder to the display all of the time to change settings, it's all on whichever you want. It has diopter adjustment which is a big help for those of us who need it.The feature set is so rich with this camera and I haven't done it justice but you can read of the camera's excellence in other reviews. I will update this review occasionally, as I learn more about the a57. It is now my primary camera.Thanks for reading, hope this helps you to make an informed choice.

This review is specific to the camera I purchased from Replay Tech in November 2017. Now, 4 months later and the camera has stopped functioning. It began sucking the battery dry while turned off, to the point the battery was dead if left in the camera overnight. Yes, it was used but was advertised as in 'excellent condition' with almost no signs of use or wear. Seems something that I paid $300 for would last more than 4 month. Last night, I tried taking photos but the menu and FN buttons were going haywire as was the center dial. Even the slightest touch and it would scroll madly through the selections and tabs and land randomly wherever...but never where I needed it. The flash would pop up unexpectedly and would not close until the camera was powered off. I requested a return/refund and was summarily denied. So, keep that in mind if you're thinking of buying anything from Replay Tech, especially if it is a Sony A57 in 'excellent' condition. I have been blocked from leaving seller feedback.

Item was returned.

I purchased my Sony A57 from Amazon it arrived without any problems, it could have been packed a little better, the camera box was packed loose in a larger box with no padding and was free to move around freely in the larger box. I have taken a couple hundred test shots using all the functions and this is my report:This camera has a nice weight and feel and very fast and is fun to use. The 18-135mm kit lens is really nice and pretty sharp but very soft around the edges, the colors this camera takes are beautiful and true to life, but I'm getting grain (color noise) in the shadow areas even at ISO 100 and it really shows much worst at ISO 400 and above in bright light outdoor photos. At ISO 1600 and above with available light photos indoors the whites really show color noise pretty bad. The software that comes with the camera is horrible in my opinion and the instruction manual is a joke! I encountered a large dust spot on my sensor in the upper right hand corner. Fortunately, I was able to remove it using a Giotto blower. I put my lens on the camera when I received it and never removed it, this spot came from the factory! In conclusion the images are sharp and colorful, and there are tons of special features. Since this camera is very inexpensive you really get a lot for your money. I also want to mention that I'm not a new comer to photography or DSLRs. I was a wedding and portrait photographer for over 25 years and my travel photos are all over the web and are very well acclaimed. Not a bad camera but not outstanding either, it is however a good buy!
