Sony Alpha A450 - Test Shots

Sony Alpha A450 - Test Shots - ISO Performance

Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using shaded natural light.

----

This is the full frame at minimum ISO.

----

Image quality at 200 ISO is very good, with no visible trace of noise.

----

At 400 ISO there is some distortion in the red channel colour gradient, and a light dusting of noise.

----

At 800 ISO the noise reduction kicks in and blurs out some fine detail.

----

Noise is again visible at 1600 ISO.

----

Noisier still at 3200 ISO.

----

More noise at 6400 ISO, and colour distortion in the green channel too.

----

Image quality at the maximum 12,800 ISO is very poor, with lots of noise and little fine detail.

----

This is the full frame at maximum ISO.

You guys realise that this camera has been available for close to 6 months or so... so isn't all that new?

fatmikel - Yes, we know. Unfortunately we're limited by the availability of review samples supplied by Sony. Usually we're able to get samples within a month or so, but sometimes there is a delay. If it's any consolation I'm hoping to get the A390 in very soon.

Seems like this a very basic DSLR dressed up in a fancy shell. The kx does everything and a lot more in a much smaller package, and similar price.

Smoke and Mirror!

That is the business model and philosophy that Sony use for all of their new products. instead of listening to their customers for feed backs, Sony produced clones of cameras from their competitors. And service supports are almost non-existent.

Sony as a business entity is dying slowly, their Walkman had been replaced by Apple I-POD, their playstations is lossing to X-Box and Nintendo, their TV is overwhelm by Samsung and Panicsonic, their camera are being overshadowed by Canon and Nikon.

So far, the Sony NEX-5 is the only DSLR camera that meets the photography market standard, all the other Sony DSLR cameras lack features(like movie mode) and are too expensive compares to other manufactors.

I just picked on of these up at Comet for £300 and now it is on sale for £330. How does that effect the numbers? It is cheaper than many other things on the market.

Yes £300 is true price, that's why I got it. Cos you wont get any DSLR for this price from others companies. So my value fro money is 10/10

@ Money your right Sony are getting dominated. They are a top company with great products but the fail badly at certain stuff. There walkman line is finished, people don't understand what OLDED technology is and sound quality Driver size, frequency etc....

Only tech geeks or enthusiasts know that kind of stuff and fully appreciate it.

@Money: 'Clones of cameras from their competitors'? Hardly. Think A700, A900 and A350 - all of which differed radically from what their competitors were doing (affordable full-frame, Live View with phase-detection AF, sensor-based stabilisation, and so on). They've lost the plot since then, but not because they're cloning competitors' cameras - on the contrary, they're removing features that their competitors would consider essential (DOF preview, MLU, fully functional A-mode, and so on).

I bought into the Sony brand with the A200 and consequently invested MAJOR money in Alpha fit lenses. I didnt require all the features of the A550 because I am more interested in producing better pictures rather than playing with the cameras features!The A450 fitted the bill with its 14.2 exmor, Bionz etc. Ok, so there are better cameras out there, but I cant use my lenses on them! In my case Sony have got this spot on. What p*****s me off is I paid £450? If you can get it for £330 its a bargain.

I started with an a100, moved onto a350 and now have a 550. In terms of how they compare relative to the opposition they've steadily gone downhill. What's been most disappointing about the 550 is noise and consequently the lack of 100 ISO. Despite the puff from Sony, the noise level from their cmos sensor is very poor, blue sky noise at ISO 100 from the old chip is considerably better than the new one at 200 ISO, at 200 ISO they're comparable. In fairness other parameters such as colour response have improved.
