The Sony A77's high ISO performance is terrible - Page 4

post #31 of 37
24MP plays a big factor here i think. And this could be fixed in the next FW just like the A700 before.

I doubt it, if the noise is really as bad as people say even in unproccessed RAW, then no firmware fix can fix it.
The only "fix" is to improve the in camera noise reduction, which I would rather do on the computer as in camera NR can sometimes soften detail too much for my likings.

sony does make sensors for nikon but that doesn't mean that sony is licensed to use nikon's own designs for sony's own cameras.

sony was always terrible with high iso performance. the sensor having 24MP isn't the issue because canon makes a great 21MP sensor with great low-light performance (5d2, 1ds3). i wonder what it is with sony's own sensor that make it that way.

according to DPR sony forums the a900 at least has a weaker *something* filter (been a while since i read the thread). its suppose to give better colors, could be completely made up just to make us feel better...

What may be visible is the increased sharpness due to higher resolution.

If your only going to print 8X10 and not crop then why buy a 24 megapixel camera in the first place though?

The whole point of adding extra megapixels to a sensor should be to increase resolution but if your doing so at the cost of adding more noise to even base ISO then your loosing much/all of that extra resolution to noise reduction. This is the kind of dishoniest marketing thats been going on for years with compact cameras and its disapointing to see Sony trying to get away with it on a DSLR.

Interesting thread. Here's a pic I snapped tonight with my A33 that I got monday.

zoomed in.

800 ISO 1/40 f/4.5

It's my first DSLR type camera and I couldn't be happier. I've used my dad's T3 at length and IMO this blows it out of the water.
