Let the living discuss this!;p

Wow.. I'm impressed by the Noise controlled. Though it's not a fair comparison, A55V beats both 5DMII and A900 by huge margins. Just look at the 3200 ISO images and above. Amazing. Makes me wanna try this camera. :think:

edit: Btw I'm not sure whether A33 and A55 are of same sensor. A55 still wins at higher ISO! Check them out!

I think different sensor a55 using a 16mp sensor while a33 is 14mp.

I am interested to get a a55 but am concern with :

1) The translucent mirror which is receiving only 30% of the incoming light. Was stated that the shortfall results in 0.5 stop only. Is this confirmed and accurate ?

2) The stationary mirror gets dirty or dust. What is the consequence ? Can we clean it with a blower or a solution Q-tip ?

The rest of the camera's specs are amazing ...........

;p;p;p

My friend ,A33 kana over heated when going a Pano sweep... I tin he did it 3 to 4 time t one shot than the LCD stated over heating... Anyone encounter this problem??

I think this mirror is not actually fixed you can also move it when you want to clean he sensor. Cleaning the mirror is much easy than the sensor it self just dont scratch the mirror when cleaning or use any cleaning agent that may ruin the mirror finish the problem here is when the translucent mirror become hazy or foggy then you'll have problem.

U think this happens to most cam. I used to have EPL1 so 100% of the time you are forced to use LCD to frame and take shot after a while it'll get very hot anf you'll see warning message on the LCD. If that happens just turn off the cam and wait for few minutes this is also true during really hot and sunnt day. Also change the LCD setting uptime from default (norally 30sec) make it 10 sec. Means LCD will auto off when there's no activity. This also saves some battery.

Bt if the over heating happens very frequesnt even at short time usage then must check with Sony CS.

Yeah Sony handle the noise pretty good but it seems to use strong NR at higher ISO making the image a bit washout but the good part for use normal user this is good meaning the photo is still usable and good for small prints

On top of A55 higher pixel count, A33 Sensor is the same as NEX 3/5 while the A55 is Sony newest Sensor (based on some review site I've read)

Hi,

Wonder if anyone of you experience the same thing. When shooting with the built-in flash. After pushing the shutter button, it takes 1 - 2 sec for the flash to fire and for the shutter to open.

Is there anyway to shorten this?

Thanks.

I have just switched from a Sony Cybershot DSC-W120 to a Sony alpha a33!
Took it out for a few shots today and I like what I see...
Bought a Tokina UV filter from Cathay Photo and got a screen protector from Sony Gallery Jurong Point.
For those who have trouble getting screen protector, go to your preferred Sony dealer and look for Sony PCK-L35WCS. It is a 3.5" wide screen screen protector for Cybershot. But it fits the a33 to a T. SRP: $19.

Cheers!

Thanks for the suggestion. But to all others.
I have to say that the protector does not fit the A33 perfectly.

A perfect fit means it fit corner to corner. This however, will have 1mm
excess in length. 1mm may not be much but
1) it will collect dust as 1 side is sticky.
2) the excess length sticks out making it easily removable by accident.
e.g. hand brushing against the protector.

just wait for the actual protector as suggested by sony. http://www.sony.com.sg/product/pck-ls1em. cheaper somemore

LS1EM 44 x 76 x 0.1mm $12
L35ECS 45.3 x 78.8 x 0.05mm $19

But can it perform in low light as wont the translucent mirror block 30% of the light reaching the sensor?

Although the high iso is not bad.

But can i say that using a f1.4 lens and iso 100 on the A33/A55 will give me a slower shutter speed compared to DSLR cameras using the same lens and iso speed ?:dunno:

 

[albertri]

i think alot of people are placing too much emphasis on so called "high ISO performance".

Those who own/have owned DSLRs before, go and look thru ur photos' EXIF file, and u will notice that in almost all situations, u will wanna use as low ISO as possible. I previously was using A550, and even though it has usable ISO of up to 3200, I always stick to ISO 200-400 if possible, else 800. Seldom go up to 1600, and i don think i ever used 3200 before.

When taking pictures indoors, flash > ISO
Night landscape, no amount of ISO can win a tripod
Long telephoto zoom (I got the 500mm F8 reflex), I still stick with ISO 400, its usually enough even at this focal length, not to mention we got build in Image Stabilizer to compensate for it.
High ISO is something that is good to hv, but its not critical.

Using high ISO performance as a comparison of a camera's capabilities is simply not realistic. If purely using ISO to compare, the Canon 1D MK4 must be a lousy camera then, as its so expensive, even costing more than the Nikon D3s and yet has lousier ISO performance when compared to the D3s.

Similarly, the A33/55 might not be the best ISO performancing entry level DSLR in the market, but it has the fastest frame rate, fastest AF speed, fastest live view, not to mention tons of functions like auto HDR, sweep panorama, and they have the biggest view finder among entry levels, with 100% FOV somemore. Not to mention some highly useful function which is not available in any DSLR in the market right now, like the ability to magnify the image in VF for micro focusing adjustment (which is extremely critical for shallow DOF and macroing), the horizon indicator (not sure the exact term), and the single most important thing that no DSLR can do, which is the absence of mirror slap. Yes there are alot of DSLRs which can lockup the mirror, but generally MLU is more useful for tripod usage. The DSLTs hv no mirror slap, thus when taking photos handheld (again, for shallow DOF and macroing), it lessen the chance of any vibrations caused by mirror actions.

I certainly feel that for $899 (body only), the A33 is simply the best all rounder DSLR you can get. The closest contender is the pentax K-X, but while the K-X hv slightly better high ISO performance, but it loses in so many other ways, the A33 simply can offer much more in those areas.

I agree with you all your points bro I am using Oly E620 and thinking of getting A55 when release I too never use ISO higher than 800 more than that it's almost a wate of shot .

Also agree with you A33/A55 is feature pack and for the price I thnk is value for money I dont minf the 1/3 stop lost due to tranalucent mirror it can easily be compensated by shutter, Aperture or even ISO... of at P-Mode just push the exposure +1/3

it's just 1/3 stop down so not that bad. The worst is you slow the shutter 1/3 more e.g 10sec make it 13Sec. This is similar to ND filter effect

For me low light (relatively) high ISO performance is critical. I take stage performances during my kids events where flash is not allowed and I have to do handheld.

Had a go at A33 during lunch today, very impressed with the build quality and the EVF. The AF is probably the fastest I have experienced in my short years of using a few cameras. The shop let me tried with 50mm f1.4 lens, very nice.

Will probably wait for A55 and weigh my other options when the other manufacturers will probably announce more new cameras during Photokina from later this month.

Getting exciting.

Nope. A33/55 seems to have adjusted the exposure by increasing the sensor gain by 0.3ev so you wont even notice any diff in exposure. Thats where the high iso performance comes into play and compensating for the light loss.

In short, the iso800 of a33/55 is notthe actual iso level, it may be iso1000 or 1250 in order to compensate for the exposure diff. But in even with this, the high iso performance easily matched the best out there.

are you on fill-flash mode ?

honestly i think the 1/3 loss isnt a deal breaker la, high iso performance isn't the only indicator for camera performance as well.

AF accuracy and speed, AF tracking , metering accuracy , white balance etc are equally important.

what i am interested to know from the a33 owners bro is , hows the battery life ! haha

So any comments on batt life usage so far ?
