The Sony A33 Live View result on DSLT is actually reacts the same resolution(very high resolution) as those DSLR rivals with Live View like Canon and Nikon and also those EVIL camera (Olympus PEN, Panasonic G-Series camera and NEX) because the lights is directly access through the sensors (for DSLR they flip the mirror up for live view)

While in previous Sony system Live View, they use secondary sensor (Phase Detection AF sensor) as the Live View on the top of the viewfinder so that we can see through the Live View under the mirror without flipping the mirror unlike those traditional DSLR do and can make Phase Detection AF together with very fast burst speed on the Live View where else traditional DSLR must rely on slow contrast detection and cannot do burst shot like what the Sony Alpha DSLR can do

Downside for the Sony Phase Detection AF in Live View system is you cannot get 100% accuracy in focusing (because they not allow you to magnify the pictures) and the Live View screen resolution was very poor because they transfer the visual through the LCD screen from the small AF sensor not directly from the main sensor

On A550/A560/A580, they use 2 types of Live View, one is the Sony quick AF Live View (Using Phase Detection) and another one the Manual Focus LV which is the traditional Live View style which display with maximum resolution and able to magnify the pictures for checking the sharpness BUT no contrast detection

On A33/A55 which is the new DSLT had break through the original phase detection system by using the translucent/transparent mirror so that the light can split on both the Phase Detection and the camera sensor at the SAME time so it can do phase detection with crisp resolution live view and EVF, because it was directly access the light through the sensor, the camera it self can do like what the rivals Live View do BUT with autofocus in very fast burst rate and focusing speed and also high resolution magnification


(correct me if I'm wrong)

lol... EVERYTHING has risks involved. Even if u buy a BRAND NEW set... theres some risk...

1) factory defect (you never know)
2) after you buy, suddenly u fall down and break the glass
3) kena curi (touch wood)

warranty or not... it doesnt really matter.. but of course it provides or a peace of mind.

zstan - don't be so harsh with that guy la.he's just like me when i was looking for 55200 or 75300..

Newbieeeeee - if you have the budget,for all means go for f58 (gosh i wish i had the money).warranty wise i don't think you have to be so concerned.i bought my 55200mm lens with no warranty and it has served me well without giving me any problems at all.but if your budget is kinda tight then go for the f42.yes,the performance and the angle where you can utilise the lens might differ but cut around the corner and try using your creativity to cover for the loss.hope this 2 cents of mine can be of some help to you.and by the way,compared to you,i have less gears.i don't even have a flash gun.but i am still living with it.. (although already planning to look for 1)

Note: whenever you buy a secondhand product/item (or anything as a matter of fact), they WILL be risk involved. and a little hint of luck. if you buy a secondhand item and it turns out to be faulty, then too bad... you're just unlucky... but of course you have to be smart as well, advisable to do COD rather than by postage. and the necessary thorough check of the secondhand item.

i buy my tamron first hand also giving me focusing problems at 1 metre liao...


everything also got their own risk la...@_@

terence88: No A33 body only kit. A55 body only got lah.

wingster: I love #2! The groom's expression, the catcher, and the bride! This is a classic in a very old-school street photographer way.

This picture, if cropped wide (crop off a lot of the top) would make a great two-page spread at the end with credits.

The A560/A580 can use contrast detect AF in Focus Check Live View (they renamed it from MF Check Live View).

fatnir: Then tell your friends that a SLR is not professional enough, you need a medium format Hasselblad or a large format Alpa view camera.

SLT gives very fast AF in video. There is no SLR format body that gives fast, smooth AF in video.

electron: Have you experienced the overheat issue yourself on the NEX-3?

evilhomura89: Phase detect is faster because with one look it already knows how far to focus to. However due to phase detect sensors and the main sensor having a variance it may cause backfocus/frontfocus. Contrast detect keeps adjusting focus slowly but is accurate and can happen anywhere on the frame, not just where there is a phase detect sensor.

right.. I see.


Simple! Get my metz36AF-4.. =D 2 months old only, scratches-less.. 10 months warranty.
1. U can own a flash
2. i can have a higher chance to own f58. Haha.. =D

no prob
as for the PEN, the feel somehow not so "right" compared to NEX

bro.. im confused... now u say PEN no so 'right'....

but few pages ago u said this:

*wingster, i help u do some minor correction to avoid misunderstanding , btw QLV is a capturing sensor, not the AF sensor or phasedetect sensor. the phasedetect sensor sit below the mirror box there. always been there. all other SLR design are base on this ideal by minolta.
*hmmm i think i edited too much

eh im wondering... whats the lifespan of the NEX? in terms of shutter count... (if there is)

kesian u plak want to come to damansara...i'll ask from moo if he is available...where's wonka ehh...he's nearby my workplace...can borrow from him...

adik...gi blaja utk PMR dulu yer...u kawtim straights A's ur parents wont make noise if u ask them for a brand new Cobra...no need pening2 with warranty anymore...easier rite...??? (kang speaking penang tak paham plak kan )

considering to buy A33 for my fiancee (ive tried tembak2 with a33 once, and i think it is suitable with women palm hu hu) and Minolta Maxxum AF 100mm f2.8 macro for my A550.. any comments?

ini adalah cadangan yang merangsangkan.

merangsangkan dan makan rumput bulan depan....
seriously, did Minolta Maxxum AF 100mm f2.8 is a good macro lens? is there any "cheaper and better" macro lens...?

haha... I dont know about the lenses.. But the a33 for future wife sounds good. Haha. I think sifu albnok once said he prefers the 100mm macro over the sp90... But i could be wrong, if so, my apologies.

A33 body is so small, sesuai 4 women. plus i can use as 2nd body.. ha ha..

please sifus, guides me on macro lens...
what about SIGMA 28-300mm F3.5-6.3 DG Macro LENS?
