a question on SB600, is there a faster way to disable flash instead of turning the SB600 off?

function button?

Now im using the fn button on the cam to disable flash but is there a better way? Because i prefer setting the fn button to spot metering

alpha_company : alright, I was dead wrong

though you are right, most people with D40/x/D60 go with the Sigma basically to auto-focus.

what camera do you use? Tokina 11-16 is actually very very good

ur using D90? eh i forgot D90 got 1 function button only ke?

d300 got 2 ka? yeah using the lower end d90

the definite plus for the sigma 1020 is:

- The widest u can get on a lens which is 10mm
- Has a speedy HSM (AFS equivalent)
- Can AF on D5000/D60/D40
- On D60/D40 bodies the Sigma's weight is more suitable because it is lighter

I use a D90...early ths year i owned a D60.

For those looking for 1750...wait for the VC one:

a nice addon but not necessary at that focal range..

the thing that i would really like to see on the tamron 1750 or any other tamron is a high speed motor like Sigma's HSM, Nikon's SWM, Canon's USM or Sony's SSM. or if they want to cut costs, just take out the motor so that users with built in motor bodies like D90 can have faster af with their lenses.

Yea prefer without the motor.. Would be so much faster to AF.. But added VC also not bad..

1 function button only.. the other one is dof preview button, but u can assigned it to other function also.

so, its like this? bodies that have built in motor will focus faster with lens without motor?

yup yup and yup
aah I've seen a lot of people using D90 with Sigma 10-20mm.
but the Tokina is very popular too.
you got a big decision to do mate

It's not like that at all actually. Tamron DO NOT YET produce lenses with high-speed & silent autofocusing motors like HSM (Sigma), SWM (AF-S Nikon), SSM (Sony), USM (Canon).

There's basically two types of built in motor, Ring-type and Micro.
-- Ring-type is normally found in large-aperture and super telephoto lenses.
-- Micro is used in more compact lenses. Tamron lenses which have built in motor all use the micro type motor which is slower than the internal bdoy motor. It is also noisier.

Example:

Ring-type motor - Nikon AF-S 17-55mm f/2.8
Micro-type motor - Tamron 17-50mm f/2.8 (A16NII - model number which indicate the built in motor version)

Sigma distortion is pretty ugly.

Some people like the distortion. But I don't.

yeah..me too.. afaik all ultra wide lenses have that prob but the distortion with the sigma is quite ugly at the edges at 10mm (at least imo) and the worst part is that the distortion is complex and cannot be fixed by software while other uwa's distortion is still correctable. can clearly see the faces of people getting stretched etc...just unnatural.. but if landscape only ok la..


how's my panning? the car is slow la..cant see the blurring effect in the background so much..unlike f1, a1 or other circuit races..hdr'ed it..hehe

Been playing with Sigma 12-24 on FF, Nikkor 14-24 on FF, Tokina 11-16 on D90, Sigma 10-20 on 40D, Nikkor 10-24 on D60, Tamron 10-24 on D60, Tamron 11-18 on Canon and etc.

And my vote goes like this.
For FF
1. Nikkor 14-24
2. Sigma 12-24 (Freaking wide)

For DX
1. Tokina 11-16,
2. Nikkor 10-24
3. Sigma 10-20,
4. Tamron 10-24
5. Tamron 11-18.

1 being the best right? did u test any tokina 1224?

how wide can a lens do on FF? 12mm?

on a aps-c 10mm right?

Nope. The only 2 famous UWA i didn't manage to play is Nikkor 12-24 f/4 and also Tokina 12-24 f/4.

12mm is quite well already. 18mm equivalent on FF

Does the Tokina 11-16 work with older film cameras such as the Nikon F90, F100? Anybody knows? This is because it doesnt have the aperture ring. So I know it wont work on my FM2. Also is this Tokina easy to find? I'm also reading about bad batches and focus problems on online discussions. Have you encountered this?
