You wanna know the use of 85mm focal length?


Miss Hypertune 2010 Finals, Mist Club, Bangsar.
A850 + 85mm CZ. 1/100s, f4.0, ISO400. Flash not fired.

You had been warned.....

e-jump, lets tag-team and inject 85mm poison into lwliam....

my turn:


Avira Model. PC Fair (II) @ KLCC
A850 + 85CZ. 1/80s, f1.6, ISO400. Flash did not fire.

lwliam......

LOL~! e-jump. Continue the poisoning.....


Miss Hypertune 2010 Semifinals, Mist Club, Bangsar.
A850 + 85CZ. 1/60s, f4.0, ISO400. Flash did not fire.

Hahaha.....~!!! lwliam. We love you.....

Ops, this may not be a good idea to post up these photos during puasa month.....

p/s: e-jump, i agree with you on the isolation.

e-jump, I find 135mm slightly long and DOF a bit somewhat difficult to handle... most had said the 135CZ is the better portrait prime, but I think the 85CZ did just as well. Just ask lwliam, as he had tried the 85mm CZ first hand....


Model Shoot. Subang abandoned railway.
A850 + 85CZ. 1/500s, f2.8, ISO200. Flash not fired.

No black laces for you to see here, lwliam....

For this shot, I think I am less than 3 meters away. Not 100% sure, but I know I am quite close.....

The stock 55-200mm? Wow, that is pretty impressive, I must say.

Yes. This lens had been known as a cracker of a lens when it was first launched together with the A200. Wow... what a long time ago... and look at how far the alpha line had progressed now. 3 distinct line of cameras (alpha dslr, alpha NEX and now, alpha DSLT).

Oh is it....? Yes, I am indeed somewhat old already....

p/s: you kid looks so super cute...!

Not machine gun.... it sounded more like a fan flapping furiously. Hahaha.....

Practise SAFETY!

We normally go to isolated places in a team. Can comprise up to 4 photographers, 1 or 2 models, make-up artist and 3 bouncers (just kidding). Basically we look out for each other. And we don't go there at night....

What type of softbox? There are many things in the market, all also called softbox..... there's the type that attach to the flash. another type attach to a studio light. another type is for product shoot. All also called softbox.... *hehehe*

US pricing is about RM2400 (USD 749.00) for the A55 body. But we do not know what is the pricing for Malaysia yet.

I think the pricing you given is about right. The best idea is still to physically check the product before purchasing, as these are not Lastolite Ezybox....

That was simply amazing.... exactly like how we see it in our viewfinder.....

Difficult to explain phase detect AF & contrast AF difference. This link may help:

http://en.wikipedia.org/wiki/Autofocus

With contrast AF, the camera basically has to hunt and continuously compare contrast to get the best focus. That is why you will see the AF goes from blur to sharp, then become blur again, before finally become sharp and nailing the focus (this is when you hear the focus confirmation beep). This is most obvious in PnS cameras and handphone cameras.

However, with phase detect AF, the AF module can know instantly if the subject is in front or behind the current focus point. It will also know HOW FAR away is the subject from the focus point. This gives the camera added information and enables it to quickly nail the focus. For moving subject, the AF module can even tell how fast the image is going out of phase, and in which direction (going back or going front) hence can predict the focus point.

The A55 have a mechanical shutter. Look at the videos carefully and you will notice that there is actually shutter movement in the mirror box. The limit of how fast a camera can shoot photos (i.e. the fps) is governed more by the flipping mirror rather than the shutter. So if the mirror no longer flips, then the maximum fps can be increased more easily.

btw, do yo know that the Minolta Dynx 9xi has a maximum shutter speed of 1/12000s?

don't believe me? check this out: http://en.wikipedia.org/wiki/Minolta_9xi



This is a FILM-era camera, but it has a state-of-the-art carbon reinforced shutter blades to achieve the amazing shutter speed, unmatched even to this day in a consumer grade dslr.

i think sony will go bankrupt real quick if they give full manual control in video mode on an entry / mid level camera like these.... I think the A33/A55 combo is just a first batch of products launched to test the market for new technologies and to provide indication on the direction Sony will need to take in the future.

If I know that answer, Sony would have to kill me....

yeah, i had seen photos of the shutter mechanism of the 9xi too.... but I just don't know where I had seen them. Not the photos you had just posted though. I think I saw it in an old camera magazine or something.

I wouldn't be too concerned with the noise performance since they are using the new EXMOR HD sensors which are supposed to have better noise performance anyway. You win some, you lose some....
