Sony Announces Alpha-System

[sulhan]

Hiee...Drudkh..

Frame selection has been there for awhile....even in point and shoot cams like those from HP. It allows user to select through a video stream and then select one frame to print out.

This will really mean that you only need to frame the subject and then select the expression of the person (if its a person shot) later...

Well isnt it similar to the fact the SLR with large FPS...say 8 frame per sec drive...eventually requires the photographer to do the selection post-shot. Like the bird or journalism type photography for example...you select the frames afterwards.

It goes Bratt-tat-tat-tat-tat-tat-tat-tat....and then you select later.

Now with the maturity of memory speeds and semicon state(tech)...60 fps is not impossible.
Come on...taking a shot at a rate of 60fps.....and able to select the image......

Like this...Its the time...

I didn't think 60fps is not possible. It is possible and it will be possible but there'll be limitation(s). What I mentioned was regarding your point on "60fps to solve shake", which I doubted it to be the solution. Maybe its just me. I can have AS working as slow as 1/10 but I doubt this new technology has that ability when it comes to slow shutter speed. Like the newer digicams from Sony that promotes high ISO as a solution to solve shaky hand problem, it just confuses the purpose of IS/VR/AS.

60 frames per sec, better than movie camcorder liao :bsmilie:

 

[sulhan]

Hehehe...

AS/VR/IS......all are to "avoid/reduce" shake. Due to imagers(ccd/cmos) that are nto able to capture "that" instant in time. A shaky image/blurred due to movement - are due to "all instances at that exposure time" are overlapped to form a movement blur image.

So imagine you can break these series of images that forms the blurred image and select the specific instance in that series - you will get a "one instant" no shake image. All are limited by ISO sensitivity. Sensors may not be able to capture high rate due to sensitivity limitations. Well...now that they may have "solve" that limitations.......60fps may not be a next century wonder

Data flow for such systems may require fast data feeds and processing and fast memory.....i think...its an either/Or situtation.....
You wouldn't want to put a mechanical AS when your Electronics can take of it... all about $$....the less it cost them to put it in....and the more they can make us get the perception to charge us more... Replacing an IC chipset may be easier and cheaper than a chunky mechanical AS. system.

To achieve 60fps.. the slowest possible shutter speed would have to be 1/60 then... maybe 1/80 if taking into the account of time to flip down and up.. but in any case.. if it's really flapping the mirror at 60fps.. i would have 2nd thought of using it

Well...most sensors now have electronic shuttering...no need flip many times....
FLip and stay...:bsmilie: :bsmilie: - at the same time preview on LCD:bigeyes:

Some pns cameras dont even have a shutter leaf.......it shares the shutter with the aperture...hehehe...
time change.....people change..... our cameras too

At that speed, it doesn't really matter if the mirror flips or not. Its pretty hard to follow through the subject you're shooting, especially in fast action sports.

It could be, plausible. We'll still have to wait for Sony to unveil their secrets.

Imagine being able to select - Mirror mode or Live preview mode...hahahaha:bsmilie:

Lets sit back and see whats up thier sleeve.....sekali a camcorder with A-mount...:bigeyes:

That'll be excellent! :thumbsup:
We'll start a new forum call ClubDV or something. :bsmilie:
I believe forbytes will be jumping in joy! :bsmilie:

Olympus E-10 does not have shutter nor mirror flipping at all. It's so quiet that the shutter sound is emulated. It uses an electronic shutter. It has a permanent beam splitter to split the light between the view finder and the CCD and has live preview. This design infact is good as the beam splitter permanently protect the CCD from dust if used on a changeable lens design. The electronic shutter has the advantage of able to sync with flash at a much higher speed. With no shutter and no mirror, it's zero vibration and no sound when taking photo.

The tradeoff is not all the light falls onto the CCD and a dimmer view finder.

Wonder why they did not improve on this design ?

wow...compatible lenses, compatible flashes, then the bomb drops....can only take memory stick! :bsmilie:

:angry: then can tell them to stick it up their Alpha Sony Sony

2 screenshots i took off the flash, wonder what they mean.

First pic noise control chips like Canon Digic II?
Second pic: APS-H image sensor with 1.3x crop? Or Full Frame Sensor?

I'm particularly interested in the Japanese writings.

what do you guys think of this one:
Minolta (?) 28-70mm f/2.8 G
Photoshop? The lens look huge to me though.
May be will come out as Sony lens?

Yup, saw it before on some website. It was a prototype.

Some "rumour" from DPreview forum :think:
Sony Update re Digital Imaging Division

Sony has decided to make a greater commitment to the SLR camera
business acquired from Konica Minolta by increasing its stake in the
Malaysia camera body factory to 100% from its previous plan of less
than 50%. It is also moving toward participating in the lens business....

 

[yeocolin]

All these sound very promising. :thumbsup:
