u wouldnt want any of those....
u havent seen how f2.8 lense can burn a hole in ur pocket...
stick wit ur kit lense...
it fits u well...

under 2k already burn holes for you maybe...

both are under 2k.. so which is better?

i wont stick to my kit lense. sold it already.

17-50...tammy...
sigma is crap...
trust me... although i dun trust either of them...
i trust tammy more...

owh anyway...2k wont burn for me...i was worried for u...

get the tammy f2.8, you'll have no regrets.

i tried it..its great...and the bokeh is FOOOYYYYYOOO

thanks

btw, the mfd minimum focus distance of the sigma 17-70 f/2.8-4.5 is 20cm and in that sense it's much better in close up shot than tammy 17-50 f/2.8

the mfd/close up capabilities of sigma 17-70 is impressive compared to tammy 17-50. that's something to think about

difference :

mfd Sigma 17-70 : 0.20m (max. magnification ratio 1:2.3)
mfd Tamron 17-50 : 0.27m (max. magnification ratio ~1:4.5)
Sigma better

aperture sigma : f2.8-4.5
aperutre tamron : f2.8 constant
tamron better

sharpness wise on a canon:

Still confused as to which is better quality wise because I've heard that tamron 17-50 has some focusing problems on d90..back focusing or something

some of the earlier tammy 17-50 have this front-focusing issue. the latter ones with built-in motor does not have this issue

So durability and built quality, which one is better?

Which would be the one that would be less likely to have probs later on?

I have two Sigma lenses bought a few years ago. Both manual focus lenses. Somehow, Sigma applies some sort of rubbery coating on the metal lens barrel. Now these coating have become soft and gooey. The marking on the lens already come off due to this rubbery gooey substance. The smaller of my Sigma lens is also cloudy due to fungus. It is now basically useless. On the other hand, my Nikkors are still solid. Glass is clear, no gooey stuff.

Maybe they have changed the construction method since, but I will avoid Sigma lenses like the plague for the rest of my life.

I'll throw another lens into the equation for you to consider. The new version of Sigma 18-50mm f2.8.

So far, I've heard good things about it and it is possibly even sharper than the Tammy.

And the Tammy new version has problems when used with the D90 LV, especially at tele end if I am not mistaken. With all third party lenses, you will need to check carefully for front and back focus.

Its just something you have to do.

earlier tammy doesnt have built in motor laaa..so cant use on d40/d40x/d60 anyways.

Added on April 24, 2009, 2:24 pmthe sigma 18-50 f2.8 is more expensive than even tamron 17-50 f2.8 right?

hi.. me just newb in this slr thing

i'm looking for cheap macro solution, can someone pls suggest which one is better for my d60 kitlense ??

1) reverse adapter .. where should i get this thing
2) macro close-up filter
3) raynox 250

lets just assume my budget can cover up to rm300 , i just want a setup that can give me good macro at reasonable price... normal macro function with kitlens just doesn't give me extra punch and details.. i need more..

if only rm 300 buy the raynox 250 OR raynox 202 macro filter.

Anyone know what is the current selling price for D40 kit?

Around RM 1.4K ++?

Is this KL price? The package usually comes with a free bag and free 2GB sdcard?

I got the info from lowyat trade zone.

U mean new or used item? I don't think can get any new item....

Some RM1,700, some RM1,6xx. Hmm....

Brand new. Why? Discountinued?

If u wanna get D40 now just get the D60 which is available in the market easily.. and yes D40 has been discontinued and replace with D60..
