Sony Alpha DSLR-A390

Released June, 2010
  • 14 MP
  • APS-C 23.5 x 15.7 mm CCD
  • 2.7" LCD
If you're a Sony Alpha (or Konica Minolta) user that shoots mainly at base ISO, in live view and Auto mode the Sony DSLR-A390 is worth a look, and is definitely a more agreeable camera to use than its predecessor.

Reviews Word on the street for the Sony Alpha DSLR-A390


6.0
The A390 is essentially an A380 with some subtle ergonomic changes, specifically a new, more substantial grip, and a reshaped top plate.

What People Are Saying Give it to me straight

Lens

The Sony Alpha 390 is a minor upgrade to its predecessor, and ultimately, the new model can be safely summarised as 'the same camera with a new grip.
by DPReview (Jul, 2010)
However, Fast AF live view is less impressive in 2010 than it was when first introduced, and compared to a camera like the Panasonic Lumix DMC G2 (which at least matches and with some lens combinations beats the A390 in terms of live view AF speed) the Alpha 390 is bulky, slow and unrefined.
by DPReview (Jul, 2010)
Also note that in our tests, the Sony Alpha 390 gives exactly the same image quality as its predecessor the A380 (any fractional differences are well within normal margin of error).
by DPReview (Jul, 2010)

Image quality

We test to confirm the image quality is identical, then concentrate the review on the differences between the two cameras.
by DPReview (Jul, 2010)
That said, image quality at low ISO sensitivity settings is certainly good enough to satisfy the demands of small prints or screen-sized web galleries.
by DPReview (Jul, 2010)
As far as its performance and image quality are concerned, the A390 is an exact match for its predecessors, which is to say that it was fairly respectable two years ago but now sits towards the bottom end of its large group of competitors.
by DPReview (Jul, 2010)

Sensor

Detail resolution in JPEGs is acceptable, but masked by an overall softness that sells the sensor rather short.
by DPReview (Jul, 2010)
Things fall apart a bit above ISO 800 though, at which point images become very blotchy, even in small prints.
by DPReview (Jul, 2010)
At high ISO settings the A390 gives adequate performance but it's nothing special, and it is roundly outperformed by competitive cameras like the Canon EOS 550D.
by DPReview (Jul, 2010)

Viewfinder

A coverage of 95% is low for modern DSLRs, although the penalty in coverage may mean very little in normal use except that the occasional tree branch or piece of trash might appear in your images without you noticing it when you pressed the shutter.
by DPReview (Jul, 2010)
The A390 comes alive when the camera is switched into Live View mode, at which point the optical viewfinder is masked off (shown here on the right) and the LCD screen takes over.
by DPReview (Jul, 2010)
The optical viewfinder is small and dim, and despite its 'TV at the end of a hallway' viewing experience, we found that when wearing glasses, the entire image area is still hard to see from a fixed eyepoint.
by DPReview (Jul, 2010)

Screen

Whilst this ensures bright, punchy print-ready JPEGs, it can be frustrating if you want to capture a wider tonal range.
by DPReview (Jul, 2010)
Left to its own devices, in bright conditions the A390 consistantly overexposes to an extent that it is often impossible to recover highlight detail in the captured images.
