[News} Sony’s a7S Full-Frame Camera Realises a New World of Imaging Expression

[obfuscate]

The A7s focussing in low light is outstanding, focusses on things that I cannot even see with my eyes. And this was with the FE55 which does not perform well on the A7 and A7r. I will try whatever M mount lenses I have left on the weekend.

Based on DPR article on the A7r/A7s/5DIII comparisons, I certainly did not see any leap in ISO performance compared to the A7r and 5DIII images downsampled.
And in fact, those were just generic processing of the files, so with better NR and sharpening before downsampling, the difference can be even less.

Surprisingly true, agree that the "normalized" result doesn't seem like a great deal of low light advantage from the a7s. Much less than I expected even compared to the 5d3

Now this would be the reason to get the a7s. Good lowlight AF.

Buy for 2nd body ? =)

nothing that big from ISO 100 to 1600, but there is quite a difference from ISO 3200 onward if you look carefully enough. even till it hits ISO 102400.

Focusing speed remains roughly the same. From infinity to MFD, I could not detect any clear advantage of the a7S. In terms of low-light focusing, tried some indoor shots under challenging conditions, still very much a hit and miss affair switching between the a7S and the a7R. Did not test focusing under complete darkness, or where I have difficulty seeing what I am shooting.

Did you have pre AF turned on? On the A7, with pre AF turned on and phase detection turned off, my FE55 would not lock in or had difficulty locking on subjects with low contrast. It managed to do so on the A7s. Strangely for tha A7, focussing was bad in low light with phase detection turned on.

Good news for those who like to shoot with M mount lenses. I just tested the A7s with my 28-35-50 Tri Elmar. the lens worked great on an A7 with the exception of smearing along the edges at 28mm. The same applied to the Tri Elmar 16-18-21. With the A7s, I could only see a bit of smearing at the extreme corners while the borders on all sides are fine.

Given its 'only' 12MP, I feel they should price it below the A6000. FF for the masses!!!!! :thumbsup::thumbsup::thumbsup:

ya i agree on that!

don't mind a dumbed down non 4K capable A7N, N for newbie like us. I do like the per pixel image quality from the big fat 12 megapixels, reminds me of the original 5D!

The price will definitely drop in a couple of months, just like the A7 and A7r. I recall seeing prices as low as $1.7K in Hong Kong just a month or two after launch, and these had international warranty.

Silent shutter mode is good

Wow! Nice. Pretty sums up. Good for video

 

[richiemccaw1]

To the bros who have bought it, how much does it cost?

Is that a new zoom lens?

AF for stills no different. Watch 8:08 onwards. I

I definitely see improvement in low light focussing i.e. all lights switched off, especially with the FE55, between the A7 and A7s. Tried this for two nights in a row in different locations and noticed the same observations.
