A77 has HUGE noise in RAW

ogl · 09-27-2011, 12:33 AM

A77 has HUGE amount of noise in RAW from ISO200 and above.
K-5, 5D Mk II and D7000 are much better.

have a look - A77 at ISO200 is worse than K-r at ISO800....
K-7 is better too. He-he...

When I bought my first digital camera in 1999, I was advised: "You should only buy camera's from camerabuilders. Not from, for example, Trust, HP or Sony." Seems like it still goes.

I compared the A77, the K-5, D7000 and the 5Dll at 3200 and raw. The K-5 is the clear winner. The A77 is noisier, but the term "huge noise" is a stretch.

Images printed at 4x6 or 8x10 would provide negligible differences. between all 4 models

Sony made that sensor in your K-5. Today's generation of SLR digital cameras are more high tech electronic gadgets than anything else. As far as I know Kodak never produced a digital camera worth a darn.

That could easily be turned on its head to say "You should only buy complex electrical products from electrical companies..."

But anyway, back on topic

For giggles I compared the A77 RAW files with the GH2 (because I own one...). Now, I know that pure sensor performance isn't the GH2's strength, and I bought it knowing it's 'limitations', but I swear I'm seeing less noise and more detail in the GH2 files... Even more so the higher you go with sensitivity...

Odd, seeing as the A77 has a newer sensor and larger fotosites even with it's extra megapickles...

See for yourself

DPReview - A77/GH2/D7000/K-5

***EDIT*** It's probably worth reading this thread before you judge the A77 to heavily... Apparently DPR was using a beta version of Adobe Camera Raw's A77 profile. People have been reporting much better results with Capture One and others :/

I would hope so: the Pentax K-5 has noise reduction in its raw starting at ISO 3200.

There's also the matter of the transparent mirror and its associated loss of light. Comparing the A77 with the A35 or A55 would be a more accurate representation of the sensor's capacities.

I was not aware that at iso 3200 you are unable to turn off the NR on the K-5 when shooting raw.

Maybe in 1999 but today the hybrid still/video cameras are the fastest growing segment and the Panasonic GH2 is lightyears better than any Canon or Nikon DSLR with still/video modes.

Ubuntu_user · 09-27-2011, 09:42 AM

Makes me glad I've got the K-5...

Although I do imagine that the A77's images will clean up when Adobe get's things straightened out.

aurele · 09-27-2011, 09:54 AM

I just saw that the A77 is in fact, as noisy as the K7.

Is sony doing a big "back in the old days", if i may say so ?

Everyone chill, considering that we're losing a third of a stop to a mirror and adobe hasn't gotten things together yet with the conversions, I'm sure the naked sensor itself (as we'll see in the NEX7 and hopefully future Pentax and Nikon DSLRs) is more than happy to match and likely surpass the previous 16mp generation of sensors in terms of total image noise. Those who compare noise-per-pixel rather than noise-per-area can, as always, go back to their padded rooms now.

Now, saying that "Kodak never produced a digital camera worth a darn" is very ignorant. They produced the DCS-100 back in 1991 which was groundbreaking and the first viable commercial DSLR. They made a monochrome-sensor DSLR (760m) with at the time exceptional image quality. They made the Pro DCS-14 which was a FULL FRAME 14MP camera released in 2002, and STILL holds its own against the latest and greatest at lower ISOs.

(Kodak makes a lot of sensors too, just see what goes into many of the high end cameras today, including for instance the Pentax 645D.)

And where are they now?

I am fully aware that Kodak made digital cameras as I have seen many of them over the years, but none really stood out as anything other than run of the mill.

Well, the DCS-100 was as I said the first viable commercial DSLR and a revolution.

The DCS-14 was untouchable by anything else back then, 14MP full frame with no AA filter. It is still an outstanding performer.

The 760m was the only monochrome DSLR sold on the market.

"Run of the mill"? You have to be joking.

Yes, Kodak today is a shadow of its former self, but do not deny that they were a major player in DSLR development.
