got la for sony mount, it got for all brand mount C, N, S (click n snap )

what moo is trying to say is that the older sigma lenses for sony were without OS (even if there is OS for other mounts).

from dpreview, it says that
"For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an anti-shake function. As the compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement"

Something new for sony then....u can now feel the OS in the VF!

1770 f2.8, is a walk around lens 2470 f2.8 also cant beat it wide angle

it/s f/2.8-4 right??

Cant imagine the size if 17-70 f/2.8

it'll be much bigger than 16-35 f/2.8

lwliam: Shooting wide open to increase vignetting is a common tactic used for full-frame cameras. It is far more obvious.

Soony: Here is one from the A900 with Sigma 30mm F1.4 in full-frame mode hence even more vignetting:



You could say the Sony is better - it's one of the best 50mm lenses there is. However the Sigma definitely stands on its on.

0168257061: Studio Zaloon, Pudu Plaza, or any Tarita, Boeing or Sony Center or Sony Style.

Well the Zeiss T* filters are so much easier to find than the Nikon NC or Canon filters!

neo_lam: For your 16-80mm, yes.

jimlim_007: If you use Kelvin WB all the time, you will not have a problem. Use Live View to set your Kelvin lah easier that way.

gizmo_pony: The framing will be steady (but some people do not like the swimming look in the viewfinder.) Also, some lens-stabilization is very audible (if you have good ears, you can hear an annoying high-pitched sound e.g. Nikkor AF-S 18-200mm F3.5-5.6 VR.)

Sweet, 17-70mm gets an upgrade! It used to be:
Sigma 17-70mm F2.8-4.5 DC
Sigma 17-70mm F2.8-4 DC Macro HSM

Unfortunately they have chopped off 2 cm from the MFD - so the original 17-70mm is the true 20cm MFD champion with 1:2.3x magnification. The new 17-70mm only does 1:2.7x.

SpOOkY: There are Sigma OS lenses in Sony mount.

You can't turn on both OS and SSS though...

Kul | Mo0: The old Sigma didn't have OS for Canon/Nikon mount!

vignetting is a bad thing? i used to see the limix LX3 shoot with vignetting, it look like more creative...

Not all photo suit to vignetting.
But I noticed some wed-shooter their photo contain a lot of vignetting after pp. Maybe a style ?

this picture is also not in focus right...

jimlim007: The focus is on the strings near the mike. F1.4 obviously has very shallow DOF and that is why his face is not in focus.

hi albnok, for those prime lens, can we get the picture have same DOF (the person face n string), eg in this picture, can it be done?

IF the face and strings are both in the focus plane, yes. Often, guitar straps and faces are at the same focus plane when shot from right in front. In this case though, if I shot from a higher angle and turned the camera downwards, I might be able to get both face and strings in focus.

Soony: 30mm is sweet, like shooting ur date from ur sitting on a dinning table, just fine, with large apperture softening the background, w00t. but i think 1750 can easily do this, but lack of the bokeh though.

gizmo_pony: i rather pay rm400 less for Non-OS version. i'm not sure, when using 200mm, i felt SSS are more stable compare to VR/IS at the same shutter speed(although it dont physically shows in OVF). so i would stick with SSS, summore the newer alpha model will have even better SSS

i see. some time prime lens also have weakness due to dof

but you do have the option of shooting in smaller aperture to keep everything sharp, right?
