Look at the background of each comparison, notice how the back of the playing card is much more detailed for the a500 across the whole ISO range. The colour of the card is also closer to that shown in the complete image. Maybe the a500 is the better choice after all? Thoughts?

Try D300s, A550, and Canon 7D. This time with in-camera HDR for A550. For still subjects, HDR can boost high ISO performance. Could that be a ligitimate use of HDR, i.e improving high ISO performance for still subjetcs? Perhaps A550 might beat 7D with HDR.

@Suffi – Thanks. I am looking forward to toying a little more with the HDR features.

Check the HDR function in A5xx. It can be used to improve high ISO performance and it’s possible handheld.

@Suffi – I wondered about the same thing. I wondered if mirror slap might be a problem (there’s no MLU on these cameras); however, the A550 didn’t have the same problem. I’m going to take a closer look at it soon.

@mike2008 – The exposures are the same. I just used the A550’s settings as a baseline. I shot the A550 in AV mode and chimped on the histogram to get it balanced. Because of all the white in the scene, the A550’s metering was underexposing. To get the exposure more balanced, I gave it a 2/3-stop EV bump. I then took the exposure settings and shot the same with the A500 in Manual mode. So, the exposure settings are exactly the same. Oddly enough, the A500 metered the same scene a little different, so that’s the reason for shooting in Manual on it.

Hi,

I think your A500 has focus issue. Same thing happened when you previously posted A500 vs 7D shots. Maybe you can ask for a different body if true?

Interesting. There is an +0.75 EV adjustment in the A550 shot at iso12800, which the A500 doesn’t have. Why is this? Was the lighting identical?

wow… A550 is really THAT better? Nice… and I thought that ISOs will be the only thing A500 gonna win with A550 – yet it didn’t. Hehe, seems that A550 is worth it’s money.

BTW: I’ve heard that A550/500 tend to loose much more details from red color than any other while applying NR – is that true?

Sony is really trying hard to make a name of itself.
But Sony better put a movie mode in as well.

Sony usually does innovation, But the DSLRs are very retro.

Waiting to hear more from you mate.
