Pitch and yaw done by lens, roll and shift (X, Y) done by camera?

http://www.sonyalpharumors.com/full...cirption-and-new-image-samples/#disqus_thread

Read the description: it appears that IBIS is only three axis for non-stabilized lenses, and that OSS in the lens is needed to get 5 axis.

So much for A-mount and legacy glass...

A 3-axis implementation is easier to fathom than a 5-axis one.

Nope, 5-axis will work with any lens. If OSS lens is used then the unnecessary stabilisation is turned off in the 5-axis IBIS. See photo illustrating this:

No OSS lens can fix the rolling movement. The A7ii and a legacy lens will have better IS than an A7 and an OSS lens! :D

Don't worry - be happy!
 
Announced, not released...

I'm very excited about it and will buy one pronto, but it's only been announced.
 
Add the new lenses to the awesome IBIS-Sony has won the World Series!
 
Makes me wonder then the update to the 7R and 7S will be launched. I mean, the 7S was launched over half a year after the 7R and 7.
 
Canon and Nikon are changing their underwear about now.

Gift and a curse for existing a7 owners. I wonder how that will go.

Looks like it has really solid 1080p video features: XAVC S / S-Log2 / s-gamut. Nothing fancy outside of that mentioned (120p / 4K).

I wonder how the AF stacks up to the current a7 and the a6000.

Agreed - among the few Achilles heels of the A7, the battery life is certainly one of them.
Click to expand...
It's a deeper grip, so maybe there is enough room for a bigger battery... Maybe part of the (announced) 90g increase of weight lies there! :)

If that's not the case, put another spare (battery) in your pocket... ;)

All the best,
Pedro

Very impressive specs. No doubt this is will be a worthwhile upgrade from the A7 and a maturing of Sony's FF mirrorless line.

I for one hope they are still cooking up either a Nex 7 replacement or a small, light FF body. The A7II body by itself weighs nearly as much as an A6000 with 16-70 attached. I hope Sony don't abandon the Nex philosophy of small size and weight with high quality. It's a very important differentiator and one of the most compelling reasons to buy them over a midrange DSLR.
Click to expand...
Agreed. The tech is impressive but the increase in size/weight (and price - at least of the recent zoom lenses) is less welcome for those of us that bought into NEX because of its size (and the promise of high quality for reasonable prices)

If Sony are looking at the FE and APS-C ranges having different philosophies with 'performance' being the priority in the FE range and 'size' being the priority in the APS-C range (though where that would leave A-mount is an open question) then I would be cool with that, but the problem is that we have seen a reduction in the APS-C range from four bodies to two (both of which are in some ways downgrades on the previous NEX series bodies) and no new APS-C lenses for a while now which does beg the question of where the APS-C range is going

Has anybody verified whether these changes will also appear in A7rII and A7sII camera bodies???

I don't think 5-axis IBIS will work with any lens. For x- & y-shift the camera need to know focus distance for correct motion. The higher the magnification of the shot is, the more the sensor will have to move.

So on adapted lenses where the camera only know focal length the camera can only use 3-axis shift. But on the other hand x- & y-shift is really only needed for high magnification, so on most lenses it will not make much difference to only have 3-axis shift.
Click to expand...
The x,y shift and rotation of the sensor around the axis is not caused by tilting the lens and does not depend on the focal length.
Click to expand...
No, but X- & Y-shift depend on focus distance (magnification), which is not known on lenses that do not communicate focus distance to the camera.

If the lens is focused on several meter away (or further) a few tenth of millimeter shift of the camera will be difficult to notice on the image, but the same shift on a macro shot will be very noticeable.
Click to expand...
If the camera shifts by a few thenths of millimeters (say a few tens of pixels), a sharp line or edge on anything that is in focus will be blurred by the given number of pixels. So when there is only shift, it doesn't matter if the object is close by or at infinity -- you will get the same amount of blur on the sensor. If the object close by has the same image size (on the sensor) as the far-away object, then the blur will be noticable the same.
Click to expand...
No, a 1 mm x- or y- shift on the camera will result in a 1 mm shift in the scene, no matter how far or how close you focus.

If you focus on 100m away a 1 mm shift of the scene will be a tiny fraction of a pixel and will not be noticed, but if you focus on 1:1 magnification (macro) 1 mm shift of the scene can be hundreds of pixels (167 pixels on Sony A7 II).

No. The camera moves by 1mm so there is one 1mm of blurr around the edges of the image of the object on the sensor. This is regardless of the distance to the object. 1mm on the sensor is 167 pixels as you mentioned.

Exactly the same number of pixels.

Look at it this way. If you take a picture of a car and a macro picture of a toy car in a way that they both fill the frame, a shift of the camera by the same amount in both pictures will result in the same amount of blur around the edges.
Click to expand...
Sorry to chime in - but I think the impact is worse on the macro of the toy car because of the angular shift, no?

I don't really know all that much about a-mount bodies, but I thought IBIS would be the reason they would be continued. With IBIS in the A7 series and the Sony LEA4 for PDAF, will Sony continue with the SLT bodies?
Click to expand...
Otherwise, why would there have been an A77II so recently, and likely an A99II as well? There have certainly been rumors about a 36MP A99.
 
body wise yes .. hopefully they have added a user settable minimum shutter speed/quiet shutter sound as well

.. the native lens range choice is pretty poor still and althogh you can use a bulky adapter for A mount lenses just loosing a bit of battery life/around half a stop, the lens range on at least the short bright tele should be better than a big bulky video centric constant aperture zoom.

still not sure i would want to get rid of my nikon lenses and take a long term punt on Sony though (bodies come and go lenses last a lifetime) until they show they are serious about stills rather than video
