Why waste time on it, pictures and video show everything,the most important is the pricing that so far at present,the same level cam that is unable to beat.:bsmilie:
A55 or A580?

Hi, The price determines whether it is worth buying. U pay for what u get. Though u have fast AF for recording video, only 35 frames Jpeg u get on recording and playback. EVF and LCD can't
catch up. In high-end DSLR with prices from more than $6K-, RISC processors with speed of 60/40Mhz are used to speed up video /fast-moving subjects in shooting, recording & playback stages. Still images are of better IQ. It is cheaper to buy separate sets. i will wait for the coming VG10 handycam.

Bro, ....go start a thread on the VG10 and quit the OT on this thread ! ...Dslr/Dslt cannot and should not be compared with Videocams !!!
I would think the reason of not having live view during bursting is not due to lcd or evf. Reason is live view is provided by the main sensor so u cant possibly have the sensor capturing burst shots while giving live view.
The lv on a3xx/5xx are able to provide live feed during bursting, albeit with blackouts as the lv is provided by a dedicated sensor.
Maybe u would like to introduce us a DSLR that can shoot 10fps without liveview lagging or blacking out? Even the 1D mk4 or D3S which cost so much money cant hv such a fast live view.
Actually I don't think so... the sensor is live all the while... i.e it is reading the light that falls on it all the while. Hence the liveview... technically it's possible but to read out the light for liveview while the processor at the same time records the image to the buffer and then writes to the card. This is heavy lifting as each image is 16 MP, requires lots of processor power... many digicams that promise such bursts actually reduce the resolution in order to cope with the huge amount of data coming through... not surprising that the A55 is unable to show the live view at all during the burst shooting phase.

yeah the A33 one only up to about 300 plus shots... as for the A580, the older A550 could shoot close to 1k photos on a fresh charge. so it should be about there too.

dpreview put the a580 uses the same battery as the a33 leh.. so means same number of shots?
Nope. A33 uses the same battery as Nex so battery life is about the same, appr 300.
But do take note a500/550/560/580 takes around 1k photos ONLY for using the ovf. If using liveview all the time (which nex and a33/55 does), then the battery life drops about half.
So taking into consideration of smaller size body and battery, 300 vs 500 is not that significant.
In fact most m4/3, pns and bridge cameras also rated about 300-400 per charge.
Even for canon 550d also around 500+ using ovf, where if use liveview also around 300++.
So i would say a33/55 and nex battery life are reasonable.
I just dunno why there is big fuss about it. Most importantly all 300+ photos are of good quality rather than having more but lousy photos.

anybody know what is meant by
*22 Can not use contrast AF function, on the a580/560?

The Manual Focus Check LV on A500/550 has been replaced by Focus Check LV on A560/580.
Meaning to say you can still AF while the mirror is flipped up during this mode, but only with slower Contrast Detection AF from the main sensor.
From that list, it seems many of the old lens without SAM/SSM are not able to use CDAF. That's probably the reason also why the NEX a-mount adaptor is not able to AF with these lenses due to some issues.

Not quite... The non-SAM/SSM lenses cannot have the fine, smooth adjustments needed for easy CDAF. As for the e-mount adapter, it can't AF with non-SAM/SSM lenses because there's no screw motor in the adapter.

Ok got it.
So can we sense that firmware is near for the A-E mount adaptor since CDAF should be possible now with SAM/SSM lenses on A560/580?
Could be...

hi seniors
tried to read up on phase detection, contrast detection AF until i blur...
my question is what effect will it have on the non-sam/ssm lenses? especially with the new DSLRs
is it only in focus check live view where the AF relies on the sensor itself that i cannot AF with screw lens and need MF?
thanks
