kev da man: Er, the A550 does have an Exmor APS-C sensor! You mean Exmor R, using backlit technology, which I've explained, will not work on current APS-C cameras.

Backlit technology on a big sensor only makes sense when the pixel density is as high as the point-and-shoots. Let's say a 12 megapixel point-and-shoot sensor has a crop factor of 6x - multiply that to APS-C's 1.5x and you get 12 * 4 * 4 = 192 megapixels.

Conservatively, we could say that backlit technology will make an improvement once APS-C sensors have 192 megapixels.

There is also quantum technology, which we have yet to see how it performs in a practical scale.

Some people have modified the Carl Zeiss 135mm F1.8 to mount on EF mount. They don't mind the manual focus or aperture because they prefer the Zeiss optics.

Nice shot, by the way, and I like how in-your-face your picture of her is!

later you might see a [WTB] alpha to canon bayonet mount converter thread CZ or G on canon, anyone? LOL

Planning to change only. Shouldnt all primes be cheaper? But a hassle to change lens every time when I wanna shoot. Getting slow n steady instead of spending an amount of money on 1 lens.

I love my 50mm n it's always attached to my body. Just sometimes I feel its a little too tight at times. So plan to get either a 24mm or 28mm. But I'm keeping my 50mm of course.

well, the first most obvious point is, non of us are professional "editor" hence, whatever video we shoot, we never get result like those :/ those are undergone editing and encoding cut paste etcetc, look for raw video from 7D,

the point is must be friendly, out of the camera if possible, undergone PP video are just another production video that many of us can never reach. just my 2 cent

many of us do no have those type of time to edit, cut paste etc, we i just prefer 'out of camera' vid i did editing(15min to hours videos), but it was years ago, and i do not own a powerful pc, still using window XP... i doubt it can even process AVCHD properly.

now, i just throw my video(normal HD format) to my partner to do the editing, coz i am too lazy to do it . when i buy A7xx, and if i requires to edit, then no choice buy new pc lor

so if u DIY a bigger bounce card, it will result in increase of % front fill light, the bigger the bounce card, the more it light comes from front, u notice the cheek will start to pop up oily look like PNS.

The main reason we use a ceiling that's low enough to bounce is because the ceiling provides a huge space for the light to bounce from thus creating a large light source that is the main cause of 'soft' light. Isn't that correct?

I personally dislike ceiling bounce method as it'll create a harsh shadow under your subject's neck.

Then I suppose that's the user's problem aka preference.
I beg to differ. I myself using a huge bounce card and I don't see how it look like PnS. It's the matter of how one control the settings.

ieR : I am under the impression that a larger surface will be better in diffusing light. Thus if you have a bigger bounce card, it would be more diffused.

Have you actually tested out that with a bigger bounce card than the one built into the F58, you will get 'oily' effect?

I have tried strapping on a folded A4 paper to the flash head and it worked out quite well for me.

I already know how the 7D does video and their orientation-detecting zone focusing (which was a major disappointment), and how the D300s is. They have the same noise performance as the A550 by the way.

Compare that to the phase-detect-on-main-sensor patents that Sony have registered, and I would say potentially, Sony has a true APS-C video dSLR killer which gives smooth AF in video.

If you want jello shake (rolling shutter), manual focus video and jumpy auto-exposure, you can buy the EOS7D/D300s now.

is this a good lens?
tokina 80-200f2.8?

lugiamcg: Yes the D90 has a bad case of rolling shutter (a few of my colleagues have it.) I haven't played with the 550D but the 7D does have the rolling shutter effect.

I have a Cybershot WX1 with Exmor R but I haven't really recorded video from it. I'll try to.

Sony has recently launched a full-frame 35mm format CCD video camera:

CCDs have global shutters - they capture everything at once instead of scanning, so you don't get that effect.
