so,... do u still wan have a go on water theme? (waterfall, sea, underwater, water droplet, rain)

fuuyoo! salute... very nice, (better if u can WL Flash)

my opinion, dont bother, nobody will know when they look at ur photo anyway. its not like, when i see ur pic, "oh i know, he is using sRGB, limiting the constrast to 244level, saturation of 24bit, blah blah blah" even i am a graphic editor, i dont bother it, because the printer print CMYK, not adobeRGB or sRGB. my 2 cent

fung yun 2 ahhhhhhh teaser of the upcoming fung yun 2

anyone bringing laptop with webcam to the TT? can i join u guys with webcam?

5 day trip, u need recharge ur batt at least 5 times, and each time is about 500 pic taken. 4gb is enough for 1.2k jpeg, NOT ENOUGH. lol... but u can always switch to medium size (5mp) and use it, because travel, u dont really need the 10mp. recently, i been shooting with 5mp only(2mp is required for developing(printing) and 2mp is about FullHD size)... coz my pc lag when edit 10mp pic.

4gb? u shoot raw? even with jpeg, ur battery dont last that much to fill the card iether.

vgrip, buy only. but with the A550 poison so strong, and buying a vgrip now only will loose it value much later. better wait till u prepare to upgrade to A550 or A7x0...

u only have 2 option. F42 or F58. ignore the rest. everyone here will tell u, NO REGRETS.

1. A300 and brothers, doesnt has a AF illuminator, they use the pop up as AF assist.
2. attach ur flash, to use the build in AF illuminator. your tamron Will Not Hunt Anymore.

3. F2.8 advantage is not before shutter release, the advantage is During shuttle release. meaning, with 16105, F5.6, shooting the same subject with natural light, gives u 1/5ss, while the F2.8 give u a decent 1/25ss which prompt to less motionblur. F2.8 is like bumping iso to 1600 on F5.6 with less noise.

4. tammy 1750, well, Practically, its for indoor use. not outdoor with wide ground. even i rate 55200 is better then 16-105 for outdoor street shooting. (my opinion, but many prefer 16105)

u are kinda wrong and right at the same time, i am assuming as, not everyone is using A700 with F2.8 AF sensor. if u are A700, yes it helps the focusing more accurate, not faster, not improve in hunt*(hunt as it will still miss under low light + AF illuminator OFF) but A700 Have AF illuminator for AF assist, thus, well, A700 is like having the right key for night shooting, AF assist +F2.8 sensor.

well, u try this, take ur 1870 kit lens, wide, set to 3.5 and shuttle release, and pls watch as they turn the apperture down to F3.5 to snap, yes, turn down. meaning at normal, ur apperture is not at 3.5, it wwwiiiiddeerrrrr try it with 50mm F1.4, when wide open, it is not F1.4.... i think it's 1.2 ehem L lens?!?!!?

assuming not everyone owns A700, and use A300 as key model, and shooting in natural light (no flash, no external flash attach.)
like i say, not before shutter release. it does not help at all in AF. what i mean during is that, it is resposible for the shutter speed gain VS F5.6. the one that give the AI decision to release the at what shuttle speed.. shutter speed gain is a major difference.

test 16105, at 50mm F5.6 shoot subject 10 meter away,

Vs

test 1750, at 50mm F2.8 shoot subject 10 meter away...

those who owns tammy would really really know the answer and differences.

and even better is, when, very very very malang, ur flash battery dead. F2.8 iso 800/1600 on A300 still can let u continue ur wedding/event job compare to a F5.6

ronnie, does that apply to sony AF sensor?


*edit: if u say, F2.8 and compare to a AF illuminator? i'd say the illuminator helps more.

btw, the A550 has much improved sensor, it can AF better in darker area vs A300 (as both are without AF illuminator)

This post has been edited by ieR: Nov 3 2009, 11:07 PM

yea, but, each sony model has diff set of sensor design. A700 has F2.8+AF illuminator. A300 has so called F5.6 sensor + pop up as AF assist, and when u popup for assist, it will sure fire when u release. and many discussion over and over, A300 doesnt not benefit from F2.8

and summore our sony sensor design, was passing through a mirror (that mirror the image upwards into the OVF) onto another mirror behind the main mirror, mirroring down into the bottom, where the sensor is locates, which is hell of dark area. but first, the amount of light going into the sensor area, is already limited by the tiny hold of the main mirror. me and my bad english... can i write in korean? its easier for me to explain that way...

dear ronnie, only A700, 850 and 900 has the dedicated F2.8 sensor while the others are using common sensor, which wont benefit from F2.8

TRUE


hehehehe, even 550 doesnt have the F2.8 sensor, but with the new design of AF system, they are on par with A700 at night time, but still wont be as accurate as a dedecate F2.8 sensor

Faster, is lens depending, how long the focus screw, build in SAM or SSM or manual (manual is u never get to focus on ur subject.... )

it's due to F2.8 as we know, the DOF is shallow, thus, accuracy is another issue VS able to hunt or not.

on A200/300, it may able to hunt at F2.8, tit teett... but,... the next question is, is it accurate? those with A200/300 with 1750 F2.8, will sure tell, 50% accurate, 50% not accurate. but try attack ur flash gun F42 and F58, with built in AF illuminator, the accuracy increase slighty, or much better.

Added on November 3, 2009, 11:50 pmand worst part is, the main mirror only allows like 30% of light through only, so imagine u shoot at low light, how suffering is the sensor trying to get a decent focus?

Attachhhhhhhhh LOL hahahaahahahahahaha

Added on November 4, 2009, 12:07 amalso the reason why we keep insisting anyone who is thinking about getting 3rd party flash, Get F42 or F58, they have better AI, WL flash, AF Illuminator.

mmmm let me see


Speed depends on SAM, SSM, AF screw length. not how much light.

focus hunt depend on the contrast of image (thts why carl ziess has better focus at night due to it boost eh contrast of subject to focus on) (depends on light)

focus hunt accuracy depend of AF sensor design, like F2.8 sensor* i need to eleborate more, but i have difficulties to explain in english. the shape of the diod/sensor of the sensor will decide the 'pattern' it will phase detect. (depends on focus hunt above, indirectly, related to light)

all 3 added up = performance rating.

but how much a 2.8 light will affect it? not forgetting the mirror cuts off 70% of the light. F2.8 may sound double to F5.6, BUT, not forgetting our lens are wide open all time when attach, thus it could be F3.5, and 2.8 is not double of light of F3.5.. it's about 30% more only.

yes, subject futher then 10 metre. coz the AF illu cant shine that far...

but like we say, photography is not about the machine, but the person behind the machine.

so, let us be smart, try to focus on bright/lightsource, which is in the same focus zone of our subject. not rely on the machine. right? innovative.

trust me, it get worst with 16105 at F5.6 vs any F2.8 lens at natural light shooting


16-105, at 105 F5.6 the bokeh is as good(my opinion is better) then 50 F2.8
with a cobra, every lens is cantik.

*repeat from old post. "and even better is, when, very very very malang, ur flash battery dead. F2.8 iso 800/1600 on A300 still can let u continue ur wedding/event job compare to a F5.6"
