New Addition to the Collection: Sony SLT a33 Camera

Since getting my Sony Nex-5 camera, photography has been a lot of fun. The Nex is wonderfully portable and takes so many different lenses via adapter like Leica and Voigtlander glass which take beautiful dreamy pics. I’ve been drawn in by Sony’s entire new line including the new translucent mirror a55 and a33 cameras.

Translucent Mirror Technology provides performance previously unattainable with traditional DSLR technology. Using the new technology, theα55 andα33 models can continuously and quickly focus (with TTL phase-detection) while shooting stills and recording video—even in full HD, allowing desired moments to be captured in tack sharp focus, high-definition video. They can shoot continuously at up to 10 frames per second on theα55 (and up to seven on theα33), achieving shooting speeds that are the fastest in the industry for an APS-C size sensor-equipped interchangeable lens cameras under $1000.

Both cameras are equipped with a translucent mirror, which enables light passing through the lens to be simultaneously received by the image sensor and the auto focus sensor, allowing continuous shooting and continuous focusing at speeds never before possible. The α55 offers the world’s fastest 10 fps high-speed burst shooting with continuous AF (TTL phase-detection) in an interchangeable-lens digital camera with APS-C sensor.

Because of its structure, the Translucent Mirror Technology does away with the motion of raising and lowering the mirror. The absence of the moving mirror mechanism contributes to making the whole body size significantly compact compared to traditional DSLR cameras.

By eliminating the need to raise and lower the mirror between shots, the technology makes it possible to achieve focusing while images are captured. Existing systems can only focus in the interval between image capture, limiting the ability to track fast moving subjects. The cameras also have continuous Advance Priority AE Mode and will automatically adjust for the best exposure to help you get the most professional looking results.

Along with the camera’s photo capabilities, the continuous phase detect AF also works in movie shooting for the first time in the world. The Translucent Mirror Technology also allows the α55 and α33 to be the first cameras to ever maintain continuous phase detection AF while recording Full HD AVCHD video. With fast, precise phase detection AF continually tracking subject movement, even fast action and subjects that move quickly towards or away from the camera are easy to keep in focus.

With a large 16.2 megapixel (for the α55) and 14.2 megapixel (for the α33) Exmor APS HD CMOS sensor, background defocusing effects can be easily captured. The APS-C sensor size is nearly 20 times larger than a traditional compact camcorders’ 1/2.88 type image sensor, providing more creative control.

Compatible with all A-mount lenses, video and photography enthusiasts alike can choose from macro to telephoto lenses to achieve their desired artistic effect.

These are just a few of the key points for the a55 and a33. I decided to grab an a33 body only as I didn’t want to bother with the kit lenses. The a33 has the slightly smaller 14.2 megapixel sensor and a smaller buffer allowing 7 shots per second as opposed to 10 in the a55 and the a33 lacks GPS. Other than that they are pretty much the same camera.

They are also much smaller than typical DSLR’s which is another reason I was drawn to them especially when paired with smaller lenses like the first lens I used today, the Minolta 50mm f1.7 RS. This lens is only 186g and sits at 38mm long.  Paired with the a33 the combo barely exceeds 600g in total weight.

I received the camera this morning and decided to take it out during my walk with our Shiba Saku and maybe snap a few portraits of the dog and my wife and I didn’t really expect to be taking high action shots but that’s what ended up happening when we hit the open field near our house and ran into our neighbor and their Shiba . Even though the 50mm is not a great focal length for action shots it worked quite well and I was very happy with the lens’ quick focusing and vibrant warm colors which Minolta lenses are known for.  Working with a prime is challenging in getting in the right position without a zoom so I found myself scrambling around for the shots but the a33 performed admirably thanks to its quick and accurate focus.

Glad to say this will be my camera for all our golf club shots in the next few months as well as the camera accompanying me to the Japan Golf Fair which is believe it or not less than 3 months away!

Here are some of the pictures I snapped today with this combo (note the last pic was taken with a Sony 30mm f2.8 Macro lens)
