josseee: "significant improvements in image quality" does this mean the optical formula was changed? I doubt that, since the elements info looks the same as previous version, the length and weight also looks more or less the same (VII seems to be 2 grams lighter) Anyway, since my old 24-70 is already deadly sharp as it is and my only concern about "not so great" bokeh in some situations seems to be unresolved, I will skip this one...
Still good to see that sony is giving something to the A mount crowd

same concern here. but maybe SONY uses better speical glass to deliever better IQ, in same fomulation. or slightly addjust the design of some glasses.

because my copy of 70200GII has show much better sharpness wide-open, comparing to GI.SONY shows the same optical-formulation as well.

TristanW: f1.4 /F2 sharpness looks a little bit soft. Can any one help to comment that?

it seem not as sharp as my 50/1.4ZA @f1.4, but MTF shows should be a lot better.

Yes, the 'close up'shot is ok, the eyelash looks good. Just when i check the landscape shots, especially the later ones with F1.4/F2.0, i expected them sharper.

Maybe i expected too much.

On Sigma goes wide with 24mm F1.4 DG HSM Art lens article (184 comments in total)

like to know the F8 MTF. so far, sony F2 ZA has a slightly better wide-open MTF.

for this 24 prime, i would like to go for FE verion, maybe will have a better edge/corner IQ.

TristanW: seems the battery life of Canon's new body, is gettting shorter & shorter.

actually, i'm comparing it with a99/a77MII. Previously, that's a obviously 'shortcoming', but now, the gap looks smaller.

In reply to:

Naveed Akhtar: Very happy with the 5x-IBIS and better handeling

But few things you don't wanna know about A7 ii
- unimpressive native lenses
- no touch screen functionality
- no 4k video support
- no e-shutter

and few things I want to ask about A7-ii
- Does its shutter release sound as loud and terrible as the original one
- If it gonna possibly support 4k video with a future firmware upgrade, even with a crop mode?
- Any possible kit option with 35mm prime lens

Rumored upcoming a9 would likely to implement all your wishlist, maybe.
a7II is positioned as entry level even in a7 family.

In reply to:

Wilight: I already bought the A7s and was intending to buy the A99 just to use the Zeiss 135mm 1.8 + IS. So, I have some questions about A99 vs A7 II.

I know that ergonomically A7 II + LA-EA4 + Zeiss 135mm would not be that good, but I'm more concerned about the IQ/results.

1- In this specific case, could this new 5-axis IS give a better stabilization than the A99 system even having to be connected through an adapter?

2- What about the sensors? Is A99 worse in low light just because of the translucent mirror (which the adaptor also has, anyway), or the A7 / A7 II sensor is really different/better?

I would like to wait for 1 more quarter, to see what a99m2 looks like.
If next generation SLT will comes out with it

Very nice summary!

Of course,i can wait for studio test shoot to find out the answer. But i'm still wondering if gapless on-sensor micro lens design is implemented or not. Just because Sony store(online) US has listed out it as 3rd highlight.

In studio test, a7 has more color noise even comparing to 1-2 year older RX1R (from iso3200 /6400 &above). Just hope a7II, launched in end-2014, can have at least 1-stop improvement.

Rooru S: So far, EVERYTHING in Photokina by Sony is aimed for E-mount cameras. Maybe it's time to sell everything I got of A-mount and jump ship?

looking at a77MK2, especially the new AF moduel, i guess sony is splitting the announcement of FE mount and a mount.
took the best options from both FE & a mount, that would be perfect.

waiting for 24/1.4 art.
especially if sony FE mount has no plan for F2-F1.4 24 prime. I will take sigma DSLR version.

comparing to rumored A7, D610 might be somewhat out-dated....

bobbidog: Sample shot DSC01165 (the one with the two birds) - is this really an ISO 125 example? I am a bit disappointed concerning all the smearing and loss of detail ...

DSC00141 looks very sharp.
