hkhk: Also, a F5.6 line-pair AF sensor would look through 2 points of a lens, while a F2.8 line-pair AF sensor would look through another 2 point of a lens (further away from the center, compared to the F5.6 one). If the lens is irregular, it might cause problems where the AF system thinks it is in focus but it is not.

Then, there is the aperture-related focus shift - some lenses like the Minolta/Sony 50mm F1.4 and Nikkor 50mm F1.4D exhibit this, where even if you've focused using a F2.8 sensor, when you use a different aperture, the focus shifts. The new Sigma 50mm F1.4 HSM and Nikkor AF-S 50mm F1.4G have been redesigned to avoid this optical design problem.

On the plus side, from the A900 onwards, Sony seems to have added compensation for these tricky lenses. The Minolta 50mm F1.4 used to be notorious for focusing issues but I don't get it anymore on the A900, A230 or A330. Some new A700s also are good, but I have not done a survey at a TT - often there are many cameras with perfect focus; it's only that we hear a lot about backfocus from the few who have it. Some on Dyxum who have sent their cameras in, suspect that they flashed new firmware that corrects for the tricky lenses, too!

Sorry... i was referring the SAL55200 in yr geavity...

i brought mine 100 last year from yanick

Thnx for the very detailed info. Will keep my 55200 for now and learn to take better pics first, and save for better glass when i out grow the kitties...

any macro sifus here shot bee before?
what is the "safe working distance"/tips for shooting bee? XD
i wan to take macro of bee but... scared kena sting by bee..

Today Test results come out suprisingly... The Tamron on my A100 seems to have higher accuracy compare to my A700... or could be the A700 advance F2.8 Spot focus confused the real focus area..

Could be the higher noise level on A100 tat makes it look sharper n in focus... im getting very depress now......

Does Sony Alpha things do price down after 1 January?
After the AFTA which all tax goes down..

Not Sony...

No brand one..

Bought it at lowyat (sri computer)

ala... come la... later we push to the front like I did during mr muscle that time... hahahaha... also using kit lens that time woo... come la... come la... also wan to test out the 1750....

Yup2... I pushed my way to the front to get better view and angle... hehehe...

Ok la... I'll get the 1750... hehehe... since I might be getting a Tamron SP90 and 70200 f2.8 sometime next year also... hehehe...

Ya la.. hezda... come la... come la... 8 least we can meet up...

hi guys .. morning ..

any of u here want to sell your BG for A700? .. .. thanks ..

morning guys..jsut back from another tiring night..sigh..feel like quitting sometimes..lol

wah..u getting 70200G ?? >.<

aiyer... don't poison... not the G... but the T(amron)...

Tamron 70-200 is really nice. Just such a pity that a "fast lens" like that can't do fast action photography coz of the lame AF. if u need fast AF take a look at the Sigma instead.

how bout the 1750? is it a fast lens? or the Tokina 28-70 f2.8?

A shot I took few weeks back



C&C please

nice one... but the head in front kacau la... should try and crop it and just show the fireman...

ianho: The Tamron 70-200mm F2.8 for Alpha was pretty alright on the A700/A900 because it's screw-driven - anything you've heard about lousy AF is on the Canon/Nikon versions with Tamron's micromotor inside.

It let more frames fire during a simulated catwalk comparison between the Tamron 70-200mm F2.8, Sigma 70-200mm F2.8 HSM, Sony 70-200mm F2.8G SSM and Minolta 80-200mm F2.8G HS. Some people might also like how the Tamron has less longitudinal chromatic aberration (bokeh CA). Would also agree that the Sigma is weak at 200mm.

Braynumb: Eh don't simply buy lah. There is a big difference between a zoom that starts at 17mm and 28mm.

Haha yeah terlupa bout that one

One Noob question : Does EV = 0 means the shoot is underexposed a little bit? When i shoot EV=0 and EV=0.3 / 0.7 the results are different (more properly exposed)
