The SLT-A33 hits a home run with its groundbreaking design for capturing crisply focused photos and detailed HD movies. Sony's innovative Translucent Mirror Technology works to deliver professional-grade, high-speed continuous shooting at up to 7 frames per second. Plus it makes for visibly faster, more accurate autofocus in its live view and movie modes. A new electronic viewfinder that displays comprehensive shooting information and a flexible tilt-and-swivel LCD screen make it easier than ever to get fantastic looking shots of a fast-moving world.
Traditional DSLRs rely on a moving mirror that flips out of the way when you press the shutter button. When that happens, the camera momentarily loses its ability to autofocus, and your viewfinder or live view LCD screen go black at the same time a less than desirable situation. Sony's fixed-position translucent mirror works around the problem by splitting the light coming from the lens, sending it to the camera's imaging sensor and autofocus sensor simultaneously. That means the 'A33 can continue focusing and shooting at the same time. Fast-moving subjects will always stay sharp, whether you're snapping still shots or recording full HD video.
Get everyone in the picture, even in 3D
The SLT-A33 also has other cool tricks up its sleeve. The next time you find yourself admiring a stunning mountain vista or beautiful cityscape, you can put Sony's ingenious Sweep Panorama mode to good use. It lets you capture the scene around you by sweeping the camera across your field of view the camera automatically stitches multiple shots together to form one seamless photo. The 'A33 even lets you record your multi-shot panoramas in stunning 3D for playback on a compatible 3D television. You can connect the camera directly to your compatible HDTV with an optional mini HDMI cable.
You don't have to be an expert photographer to use an SLR they all offer easy automatic shooting. Because of their build quality and the physics of good glass and large sensors, even their built-in automatic settings will get you better pictures than most point-and-shoots or mobile devices. But experienced photographers and budding hobbyists can get more creative by manually adjusting settings like aperture and shutter speed. SLRs let you expand your shooting options with additional lenses and flashes to suit just about any situation. If you'd like to record the occasional video, look for a model with high-def movie mode.
A VERY amateur photographer, I am a bit disappointed with this camera. I got much better shots from my Sony A200. After pressing the shutter release very often this camera seems to pause and process before actually snapping the picture - this means that a moving subject was no longer in my frame! The built in menu guides and explanations seemed like they would make this camera so much easier for an amateur like me, but in reality they have not improved my photos. I think you need to be very tech-saavy to learn to use this camera effectively. EATS BATTERY LIKE CRAZY - even professional review comment on this, so I know it's not just me.
Pros: nice, small size; video feature; swiveling LCD screen; LCD screen or view finder can be used for shooting; menus, settings can be read in viewfinder (nice for bright situations)
Cons: EATS BATTERY LIKE CRAZY. TWO ARE A MUST. If you are traveling where there is no electricity to recharge (like in Africa) and plan on taking lots of shots, two batteries will be dry in two days - without taking any video. This is my BIGGEST complaint.
Many features on this camera are so good but I'm having trouble getting sharp
pictures. They look excellent on the LCD and in the viewfinder when played
back but if they are enlarged at all they are not sharp and mostly soft and out of
I'm using a Minolta 50mm 1.7. I am trying all the aperture and shutter speed
I am not new to photography as it has been a hobby of mine for at over 50
My previous main camera is/was a Minolta Maxxum 600si. Which always
produced sharp photos. I have a pocket sony DSC-W100 that gets sharper
photo's then the A33. I have experimented a little with the auto focusing points
but so far manual focus has proven superior to the auto focus.
I've only had the camera a couple weeks maybe I'll find a way to make it work yet
I have not contacted Sony or Crutchfield regarding this yet. Will see if there is
something I can do first.
This is an excellent all around camera for novice to pro. Don't let the Canon crowd fool you, this setup is 1/2 the price of comparable Canon. The biggest limitation and hidden info, is the HD video is time limited, especially if you are using the stabilization mode. Most people have camcorders though for this purpose, so probably not a major issue. I have numerous lenses I use, and sold my Sony A350 to upgrade to this. I have not been disappointed, as this camera has it all, from full auto, to full manual, with everything in between !!
I've been looking at Sony digital SLRs for several years, primarily because I have a
stockpile of older AF lenses that I really don't want to give up. This camera is
great for the casual photo taker. More robust and feature rich than the less expensive
camera, but not wallet busting like the top of line models.
The burst mode is great for shooting sports and wildlife (or pets), and the panorama
mode works pretty well for landscapes.
The HD video is very impressive, however the one downside of the camera overall is
one of its best features, the continuous autofocus in video mode. The sound of the
autofocus is very audible in the video, so if you're planning on using an external mic,
make sure it is one that won't pick up on-camera noise, or alternatively, just use the
I'd recommend this camera to anyone looking for something that they can use in any
situation, and especially to anyone that has old lenses lying around.

Camera Body Only: The Sony SLT-A33 α (alpha series) DSLR camera is compatible with Sony A-mount lenses. This product contains the camera body only, along with a rechargeable battery, adjustable neck strap, USB cable, and software on CD-ROM. No lenses are included.
Translucent Mirror Technology: The A33 is the first DSLR with Translucent Mirror Technology, which directs light to both the image sensor and the Phase Detection AF sensor simultaneously. This allows the camera to focus and capture the image at the same time. Since the mirror never moves, the time needed to raise and lower the mirror is eliminated.
3" Tiltable LCD Screen: The A33 uses a 3" TFT TruBlack LCD screen with 921,600 dots. The LCD can be tilted and swiveled so you can frame your shots from difficult angles overhead or down low.
Electronic Viewfinder: The 0.46" electronic color viewfinder has 1,440,000 dots (0.43"/1,152,000 dots displayed), and provides approximately 100% field of view. The built-in diopter lets you adjust the viewfinder image to your individual eyesight. The adjustment is -4.0 to +4.0 m-1. If you're using the electronic viewfinder to frame your shots, the LCD turns off automatically when you bring the camera up to your eyes.
Live View: The A33's Live View lets you use the LCD screen and Electronic Viewfinder to frame your photos as you shoot. The Live View image will provide an accurate preview of your photo, including the white balance, focus, depth of field, exposure, and framing. In addition, the on-screen displays will keep you informed on all your settings and recording information.
Still Image Recording Formats: Still images are recorded in JPEG file format in Standard and Fine compression rates. You can also record still images using the RAW format, which is uncompressed with no processing performed in the camera. RAW images must be transferred to a computer for processing, editing, and printing using the supplied Image Data Converter SR software.
Movie Recording Formats: The A33 can record 16:9 Full High Definition movies (FH: 1920 x 1080/60i) in AVCHD mode with MPEG-4 AVC/H.264 video and 2-channel Dolby Digital audio. Movies can also be recorded in MP4 mode (1440 x 1080/30 fps, 640 x 480/30fps) with MPEG-4 AVC/H.264 video and MPEG-4 AAC-LC 2-channel audio. The recording bit rate is 17 Mbps for AVCHD, 12 Mbps for MP4 1080, and 3 Mbps for MP4 VGA.
Panorama Photos: The 3D Sweep Panorama mode lets you record panoramic images by holding down the shutter button as you pan across the scene. Panoramic photos can be taken in 3D or Standard in several different resolution settings:
Dual Media Options: The A33 camera accepts two types of media for capturing still images: Memory Stick PRO Duo (including Memory Stick PRO-HG Duo), and SD, SDHC, and SDXC Memory Cards. The maximum number of images that can be recorded on a memory card formatted with this camera varies slightly between the two types of media. The number of images that can be stored on a Memory Stick PRO Duo:
Capacity based on images taken at L 14M/Aspect Ratio: 3:2 (4592 x 3056):
|Size \ Capacity||2 GB||4 GB||8 GB||16 GB||32 GB|

|S: 2.9M||2288 x 1280|
SteadyShot INSIDE In-Camera Image Stabilization: The SteadyShot INSIDE in-camera image stabilizer shifts the image sensor to compensate for camera shake without sacrificing image quality. The compensation effect is equal to 2.5 to 3.5 shutter speed steps, giving you more creative freedom when shooting in low light. And, because it is integrated into the camera body, SteadyShot INSIDE technology works with all compatible α (alpha) system lenses.
Eye-Start Auto Focus: The camera features the Eye-Start Auto Focus system, which begins precision auto focus adjustments the moment you raise the camera to your eye. This feature can be turned off in the menu, if desired.
15-Point AF System: The A33's high-performance auto focus system uses 15 focus points to deliver fast and precise focusing. It has a predictive focus control to automatically calculate the position of fast-moving subjects. You can choose from the following Auto/Manual Focus Modes:
Focus Lock: If a subject is off-center and outside of the AF area, you can lock the focus of the camera.
AF Illuminator: When you press the shutter button halfway down a red illuminator is emitted until the focus is locked. Under dark lighting conditions or when you shoot a low contrast subject, the AF illuminator allows the camera to focus more easily on the subject. The AF illuminator has a range of approximately 3.3 to 16.4 feet.
Drive Modes: The camera offers the following shooting modes:
Exposure Modes: The camera offers the following exposure recording modes:
Exposure Compensation: Exposure compensation is used to alter the camera's standard exposure setting. You can make the image look lighter (increased exposure) or darker (decreased exposure). The exposure compensation amount can be set up to +/-2 EV in 1/3-step increments.
AE Lock: You can fix the exposure before deciding on the composition when taking a picture. This is effective when the metering object and focusing object are different or when you want to shoot continuously while keep the same exposure value.
Metering Mode: A 1200-zone evaluative sensing system provides multi-pattern measuring for superior exposure control accuracy in a wide range of lighting conditions. You can select the method for measuring the brightness of a subject from the following three methods:
White Balance: You can adjust the color tones according to the lighting conditions. You can choose from the following WB options, and adjust the +/- 3 to fine tune the colors:
Color Temperature/Color Filter: You can adjust the white balance further by selecting Color Temperature or Color Filter in the Custom White Balance option. With Color Temperature, the higher the number, the more reddish the image, and the lower the number, the more bluish the image. Color Filter achieves the effect of Color Compensation filters for photography. Based on the set color temperature as the standard, the color can be compensated to Green (G) or Magenta (M).
Image Processing (Creative Style): This camera is pre-programmed with image styles optimal for various scenes and purposes. For each setting, you can adjust the contrast, saturation, and sharpness. You can choose from the following settings:
ISO Settings: ISO is a unit of measurement of sensitivity to light. The larger the number, the higher the sensitivity. The camera's ISO can be set manually or automatically, depending upon the exposure mode:
Built-in Flash: In a dark location, using the built-in flash, or optional flash, allows you to shoot the subject brightly, and it also helps prevent blurred photos due to camera shake. The SLT-A33 features a pop-up flash, and an accessory shoe for attaching an optional external flash. The range of the built-in flash depends on the ISO sensitivity and aperture value. The A33 offers the following flash modes:
Noise Reduction: The camera offers Long Exposure and High ISO Noise Reduction (NR) to automatically reduce the grainy noise found in photos during long exposures or high ISO settings.
Anti-Dust Technology: Changing lenses in a DSLR can allow dust to enter the camera. To help keep the image sensor cleaner for better pictures, the A33 utilizes a static-free anti-dust coating on the imager's filter. The camera also has a cleaning function which vibrates the image sensor for a short time to knock off any dust that may have settled on the imager.
Playback Options: You can view images on the LCD monitor with 3 options: with recording data displayed, without recording data, or histogram display. A histogram is the luminance distribution that shows how many pixels of a particular brightness exists in a picture. The histogram display of this camera shows the brightness on the horizontal axis (left side is black, right side is white) and the number of pixels on the vertical axis.
Auto Review: After an image is recorded, you can have the camera automatically display it on the LCD monitor for two, five or 10 seconds. You can also turn off auto review.
Image Rotation: Vertical shots can be rotated automatically so that they are displayed upright during playback. This can be done manually or automatically.
Playback Screen: You can view your photos back as a single image on the LCD monitor, as an Index or as a Slide Show . During Index View mode, you can view 6 or 12 images at once. You can adjust the Slide Show mode interval from 1, 3, 5, 10, or 30 seconds.
D-Range Optimizer/Auto HDR: The camera allows you to correct the brightness and contrast of an image automatically, using the D-Range Optimizer (DRO) and Auto High Dynamic Range functions. The DRO optimizes the gradations of a recorded image in each area of the image; you select the optimal level from Lv1 (weak) and Lv5 (strong). When Auto HDR is selected, the camera shoots three images with different exposures, then overlays them to create one image with the correct exposure and an overlaid image.
Image Enlargement: During single image playback you can enlarge an entire image or a select area of an image from 1.1 to 11.8x depending upon the image size. Small images can be enlarged up to 5.5x, Medium images to 8x, and Large images up to 11.8x. Once you have enlarged the image, you can pan around the image to view the desired portion.
Rotating Images: Images can be rotated counter-clockwise 360-degrees on the camera's LCD monitor during single image playback.
Protect Images: You can protect all images on your memory card or select only certain images to be protected from accidental erasure.
HDMI Output: The SLT-A33 provides direct mini-HDMI output to your HDTV screen, so you can view and share photos in clarity and detail. You can choose between standard 3:2 or widescreen 16:9 aspect ratio. When connected to a Sony BRAVIA TV, you can control the image playback using the TV remote. A mini-HDMI-to-HDMI cable is not supplied.
Printing Options: The camera offers the following printing options.
InfoLithium Battery: The SLT-A33 is powered by the NP-FW50 InfoLithium battery (supplied). The battery communicates data to the camera, so that the percentage of battery power remaining can be displayed. The approximate number of images that can be recorded with the supplied battery is as follows:
|With Flash||Without Flash|
|LCD Monitor||340 images||380 images|
|Viewfinder||270 images||290 images|
Charging: The supplied InfoLithium battery requires approximately 250 minutes for a full charge. The battery should be fully charged before initial use.
Power Save: You can set different time intervals for the camera to switch to Power Save mode. You can set the interval to 10 seconds, 20 seconds, 1 minute, 5 minutes, or 30 minutes. Once the camera goes into Power Save mode, you can return to the shooting mode by pressing the shutter button halfway. When the camera is connected to a TV or the drive mode is set to Remote Commander, the power save mode defaults to 30 minutes regardless of the setting.
