1) yap...some days ago i saw lightroom taking 2.9gb on my Windows 8 laptop...so i upgraded to 8gb...as the people shooting videos would upgrade to 650D if the new autofocus in live view mode would turn out a useful features even without ml
You should upgrade your memory to 8GB years ago.  Memory is a small investment and bring huge benefit if you use PS and LR.  None of my computers is running under 8GB of memory.

So...I don't suppose anyone knows if rolling shutter has been improved or not on this camera?

Besides, Digic 5 is VASTLY more important than pixel count, vastly.

In additions to the good replies above, I have to say I'm at a complete loss how people can think the cpu is the most important part of a dslr when it's mainly shoving pixel data from a (sensor) to b (card). Sure it can do in-camera jpeg what you could only do in postprocessing before (nr, ca correction), it might save some power and for video noise reduction it's certainly important, but that's about it.

If someone offered you two computers, one with windows 8, 256mb of ram, on-board gpu and a core i7, the other with windows 7 (magic lantern!), 4gb ram, dedicated gpu card and w/ a core i5 - which would you take?

Pixel count over processing, really?  Good luck with that one.  Besides, I never wrote that "the cpu was the most important part" of a DSLR--it's A/F accuacy followed by A/F speed.

Canon lost around 18MP, saying this is a brand new technology. sick of u.

didn't they know about 3200???

For most entry level users I think they've taken the correct route, FF DSLR's like the D800/5D mk3 are one thing as most buyers there are going to be willing to invest in quality lenses but 90% of entry level users stick with either kit zooms or superzooms. Those lenses(and indeed many more expensive ones) simpley arent going to make the most of 24 MP while the extras on the 650D(better AF, higher FPS, better viewfinder) are going to be a bonus to pretty much any users even if they don't shoot video or care about the touch screen.

Personally the impression I'm getting from the 650D is that its partly a response to the mirrorless market looking to emphasize the advantages of DSLR's with the better AF and VF.

If Canon introduce there own mirrorless as rumoured I'd guess its going to be positioned below the 650D as the entry level to large sensor cameras.

1200usd  [including lens] is a cheap alternative for entry level user???? great as long as u have money.

really important things are always missing for example flash sync speed WE WANT CANON TO GIVE US 1/500 to say the least, 1/160 - 1/200 is a joke, this "new" camera doesnt worth the stretch.

That was why Canon invented HSS so that sync speed didn't matter.

so now that they are essentially the same price and based on the info we have now, would you buy a 60d or a 650d? Ive been waiting ages to upgrade from my XS

This certainly fixes it for the most part, but as you know it's no real replacement: higher battery drain, lower flash output & no 2nd curtain sync.

For enthusiast's standards of this forum, this is extremely cheap relative to other Canon gear people are getting for their recreation -  "entry level" means "anything below the 7d" and L lenses, get used to it or buy a Nikon, you cheapo :-p ...

How are you finding Win8? - I am not keen on the new interface

The kernal is of course almost pure Win 7 so there shouldn't be problems there

my laptop is used mainly for work, so it's used more as a terminal than a workstation and i dont used PS at all, but for lightroom i have a server at work with 64gb, 8 xeon cores  and 1.4GB/sec bandwidth to a EMC2 VMAX; of course it's not a dedicated machine, i do different kida games with them.

a nice upgrade you should do is to get a good ssd for you workstations… i saw SSD Sandisk extreme getting cheap enough lately...leass than 200€ for 240GB

but we are going OT

10x for the good advice anyway

Back to the camera...  its looking to me like the new 18MP sensor itself is not making any real contributions to IQ/DR/ISO.  the marketing thrust of this camera is about the AF and in-camera jpg processing, such as the four-image noise reduction capability.  I'm just not seeing anyone suggest that ISO and noise were addressed in this sensor technology cycle.

4 SSDs in my 6 systems.  I put 128GB SSDs for my laptops and 64GB SSDs for desktops + HDD RAID.  All systems and applications are on SSDs.  HDDs are only for data storage.  Actually when you have HDD RAID, the HDD's performance are also great.  My 5 2TB RAID(total 8TB storage) can reach about 200MB/sec.

I think the value is depends on how much you care about photos.  One of my friend makes more money than me.  Last weekend he asked me which DSLR is good to buy.  Since he hasn't used DSLR, I believe T4i might be a good one for a beginner.  When he heard the T4i + 40mm is about 1K, he asked me for other suggestion.  Thus, when he asked me how much I spent for my gears, my answers is that you have better not to know.

it really looks like the same 3 years old sensor from the 7d..

basically what does the digic5 do which digic4 could not?

from wiki

"DIGIC 5 is now featured on Canon compact cameras like PowerShot SX40 HS to achieve a capture rate of 10.3 frames per second at full resolution in High-Speed Burst HQ, Full HD 1080p Videos and Intelligent Image Stabilization. The new DIGIC 5 processor is 6 times faster and creates 75 percent less noise than the DIGIC 4 processor.[7]Designed to achieve new and advanced levels of image quality, DIGIC 5 analyses four times more image information to create each pixel, recording more detail and colour from a scene than ever before. Processing speed is also six times faster compared to the previous processor, efficiently managing the increase in scene information and simultaneously reducing the appearance of image noise by up to 75%.

DIGIC 5 Is used in the Canon EOS 650D/Rebel T4i/Kiss X6 (announced June 8, 2012 and available later that month)

If I read that correctly it is saying that it used the Digic 5 for NR?

If true then surely that NR could be achieved in pp??
