Sharpness is not that great. I think the posing is not ideal to show off a little bird. Try getting a shot sideways, it's more appealing this way.

I know photographing birds is not easy, they move around a lot and everything has to come into place to get a good shot. I show off only the good pictures but if you look at my harddrive the amount of bad pictures is very high.

But at the end of the day you only need one good picture.

I think it's a little unsharp. Need to go up higher than 5.6 aperture. Shooting wide open is not going to get you razor sharp shots. I know you think you will have to raise the ISO and that is what you will have to do. Also might need to micro focus adjust that lens.

The noise doesn't bother me. The lack of sharpness does though...

Re: Is this photo noisy or normal according to you (A77+SAL70300G SSM)

I think its noisy...quite a bit really.  You should be getting better files than that and i imagine will once you get used to the sensor.  With high iso and the a65 at least, if you shoot jpegs and say 1600/3200iso it helps to set sharpness -1/-2 in settings.

As others have said the image not being truly sharp to begin with is suffering from adding sharpness thus creating more noise.

A couple a65 edits at 400 and 3200 12mp setting.-Good luck -brian

edit from a 12mp jpeg

original j -peg shop  shot in 12mp mode full size- set red back a bit to avoid a 'red burn' or blotch. thats why the balance is green/blue

Re: Is this photo noisy or normal according to you (A77+SAL70300G SSM)

Thanks Brian. Your A65 shots look very clean to me. Fantastic shots, by the way!

Since I have to shoot in RAW, the camera won't let me choose 12MP. But I really need to shooting RAW and get clean photos like ours. Looks like that is going to be tough.

This is where I hit the wall...I really don't like the photos over ISO800...too noisy in my opinion.

the focus is more on the white wall, that's why the bird itself looks blurry, if you just look at the white wall part, there isn't much noise and would be a good wall shot

Yup the focus is also an issue here. However looking at Brian's A65 photos 3200 ISO, I think I might have gotten one of the noisy A77s out there. My eyes can see noise even at ISO 100 (when zoomed in 100%). I am comparing 24MP Nikon D7100 photos (the only other reference I have as test files) and the sky has zero noise at ISO 100. So instead of having buyers remorse, I ended up ordering a A99 body only from eBay 6ave for $2023 (I think that's a good deal as other retailers are selling it for $2798).

http://www.ebay.com/itm/Sony-SLT-A99-Digital-SLR-Camera-Black-Body-Only-2-Batteries-32GB-More-/321182235263?pt=Digital_Cameras&hash=item4ac7f3fa7f

Sorry but the A77 is back on its way before my return period ends (end of Jan).

For me, since the cost was not an issue, I should have waited to see more comparisons of the A99 vs A77. I hope the A99 lives up to its expectations, considering its more than twice the price of the A77 (body). My bundle of the A77 and DT1650 was $1400 so in essence I paid $600 more. Since I already have the 70300G and the Minolta 50mm, both of which are FF lenses, I think I made a wise decision (at least my conscience thinks so).

Here is another A77 shot at 200 ISO. Isn't the noise quite visible in this sky shot (See full size)? I am afraid I might have got a bad unit as dpreview samples and the ones posted by Brian seem so noise free.

Re: Is this photo noisy or normal according to you (A77+SAL70300G SSM)

To my mind all these pictures are really really noisy.

Do you shoot RAW or JPG ?

If you shoot RAW, can you try DXO 9 (free evaluation version for 30 days : be carrefull DxO 9 is not working with XP) to post process your shoots and then please post the result again here.

The one above of the blue sky is a JPEG SOOC. But the RAWs are noisy too. Even without any adjustments. I know the A77 does produce noise >1600 ISO but I really expect clean ISO200 and ISO400 images.

The bird shots are both RAW converted in Camera RAW - one without NR and one with NR (as mentioned in the details).

Here is one exported from DxO 9 (Preset->No Correction->Export JPEG 90%)

What do you think?

Better noisy than soft either due to lens sharpness at aperture, DOF, or motion.  ISO 800 is very usable on my A700 so I certainly don't see why 1600 or higher shouldn't work fine on your camera.

Looks out of focus to me.  I'm not seeing noise as the major issue in your photographs, but either out of focus or motion blur definitely is.  Not sure which is happening in this last photo.

Thanks! In the last photo the shutter speed is 1/200 - so blurring shouldn't be an issue right? But look at the blue part of the sky.

I sold my A77 after two years and now have an A99. So I know a little about noise and the 77. Usually, you will get a good bit of noise in a blue sky.

Another thing is you can go to 2000 ISO generally and get pretty good results. I think most of your problems are the lens needs to be micro focus adjusted. And get a demo copy of Photo Ninja and try it. It's really hard to beat the noise reduction in that program.
