anly: hi, have u even been to alphanatics? there is many people selling 55-200 2nd hand under rm500. choice to choice.... if u are looking for tele.. i recomend
i. SAL55200 (better then tamron55200)
or
ii. Tamron AF 70-300mm f/4-5.6 Di LD Macro (better then SAL75300 in terms of IQ and CA issue)

for superzoom (18 to tele)
the SAL18-250 is great with shorter focusgear then other tamron, but all super zoom suffer the F6.3 and softness at end tele.

well, its up to u eh, if u top up rm100 for the extra 50mm on 18250...

but if u willing to carry 2 lens, u sure ask u get a kitlens +55-200 (sharper, F4 till 100mm)

the 18-200 is great lens too. but i never owned it so i cant comment much

if SAL18-250 compare with SAL55200, issit same IQ and CA ? or which one better? but SAL55-200 is much more cheaper than SAL18250,since i got 18-55mm lens already..  sweat.gif

+1, same here. 55-200 anytime over 18-250

cutting all the jumbo crap.... 55-200 is indeed better in all forms of "photo result". (putting practical aside)

(if u were to go birding, noone carry a 18-250 for birding, they carry straight a 70-400G LOL... kidding wink.gif i carry my 200-400 for birding)



johnmeng: u dont think u wan CC, sure get bomb only, in a photographer eye, that hurts the eye. massively UGLY HDR.

shootkk: yo bro, i shoot wedding too, my opinion,
i. get 2 body.
ii. upgrade ur anticipation skill. always change lens before the fall of event. knowing the event is very important.
iii. i shoot a whole wedding with just a 50mm, not just once, but many times. and they still stunned with my work.


-----------------------------------------------------------------------------------------------
18-250 is nothing. i sold it off after 1 year sitting in by drybox when i realize my 18-70 and 55-200 can do sharper photo.

summore, 250mm (for wedding) that distance, ur flash cant even efficiently be used la...

i can change my lens in 3 sec. i remember once the F1 (Ferrari team) missing 1 wheel during pit, the next following 30 days, all crew are to train pitting non stop whole day for 30 days. hence, today, Ferrari team has the fastest average pit time. so... PRACTICE changing lens improves you.

and to be honest, how many times a person need or fully uses a tele INDOOR?, i might just take that few step forward to snap with my 18-70/55 (i using 17-50F2.8 as kitlens)... and pls pls stop BS like that few step u lost the moment.... u should have anticipate that moment if u intent to go pro.



BUT if u are just a family man that wanted to shoot ur kids or at birthday party or picnic at the beach, just get the 18-250 and IGNORE the IQ, because it is already at the best it can offer. and u will not use the whole 1xmp to do a 50x40 large print (do u?) at most, u will put as ur wallpaper (fullHD is only less then 3MP) or 5R prints which only require 2mp to get max sharpness off it.

u are better off spending money on a F58....

Added on October 5, 2010, 11:13 pmbtw, the drawing is ALL wrong. as i mention earlier, reflection is 100%, reflection do not filter out light, unless is passthrough, then only result in 30% lost of light. the diagram sucks so much because, who the hell wan a EVF+OVF? might just use EVF la, why all the trouble to filter out more light before reaching the AF sensor?

nex has outstanding iso, it doesnt need hotshoe for flash,.... and sooner or later, they will have replacement with even better iso.... m43rd if they pack more sensor diode, it will eventually has more noise (due to the packed diodes) compare to APS-C size sensor

the EVF+OVF is to satisfy the two groups of ppl who either love or hate the current a33/55

i would think OVF plus electronic details of EVF on it is not a bad idea
*
but u see... the OVF of that design, is no diff from A300 small OVF ler... u know why A700,850,900 or D90 and 550D has large OVF? because they uses penta prism.... but which that design, without pentaprism, no matter how u say it, it will not satisfied a OVF group.

perfect10: i wont put too much hope up on bokeh. it will have a soft blur background with large aperture, but most ppl use UWA for wide shot of big object which usually end up with large DOF, hence low chance of nice 'bokeh'

im not saying it cant or doesnt have it, but at a very limited situation where u will have really big round bokeh,... mostly are simple soft background. unless u use UWA to snap miniature toys or food.

why F2 (2.8)? wedding photographer just love wide aperture lens, eg: F2.8. because the wide aperture creates low DOF hence able to isolate the background from the subjects.

eh.. i want to ask...
which 1 better a33 or a550?
i want to buy a33 but a lot of issue to the "slt" things..
they believe slt less professional than slr..

and a lot of people say that the slt is similar to sony NEX...
i don't know what's the different
can anyone tell me? biggrin.gif

please i need your suggestion biggrin.gif biggrin.gif

who? can i say, if i see a DSLR with video mode, that DSLR is Not Pro, its a lowest wanna be pro camera... will u now go and ask ppl DSLR with video is less pro? tongue.gif

may i repeat?

to define a photographer is by his(her) works, not the gear he uses.

SLT is NOT nex, not even close. very farr farr summore hahahaha...

SLT is just mumbo jumbo that sony is good in, MARKETING with lots of stupid names to confuse people. its just a static mirror that improve shooting speed, AF speed, and it still has the sensor that to capture crispy photo~ biggrin.gif

when u buy car, do u look for "VVTISWTSNTEDLSD"(seriously those jargon in car not my thing) in the car? or just 4 wheel, steering, and bring u to destination?

a camera, should snap a photo, and give u the closest result to ur settings/expectation.

but if, u were to ask does sony worth it? i will tell u, sony by far, everything, has at least 10-30% cheaper(then the 2 big brother) in budget after u completely spend on a WHOLE family of gear. wink.gif

The Sony A33 Live View result on DSLT is actually reacts the same resolution(very high resolution) as those DSLR rivals with Live View like Canon and Nikon and also those EVIL camera (Olympus PEN, Panasonic G-Series camera and NEX) because the lights is directly access through the sensors (for DSLR they flip the mirror up for live view)


While in previous Sony system Quick Live View, they use secondary sensor (Phase Detection AF sensor normal capturing sensor (low resolution)) as the Live View on the top of the viewfinder so that we can see through the Live View under the mirror without flipping the main mirror unlike those traditional conventional LV DSLR do and still can make Phase Detection AF together with very fast burst speed on the Live View where else traditional conventional DSLR must rely on slow contrast detectionflip down the Main mirror, do phase detection, and flip up mirror losing 1-2 sec before release shutter and cannot do burst shot like what the QLV Sony Alpha DSLR can do. the Phase detection Only can work when the Mirror is DOWN, so conventional LV has to let the mirror down to focus (unless u activate MF, but the closing of mirror then up again would taken a sec delay)

Downside for the Sony QLV(A2/3 series) is that, they do not uses the Main sensor to do LV, that u will not have 'zoom in' manual focus like other conventional DSLR LV Phase Detection AF in Quick Live View system is you cannot get 100% accuracy in Manual focusing (because they not allow you to magnify the pictures) and the Live View screen resolution was very poor because they transfer the visual through the LCD screen from the small AF sensor not directly from the main sensor

On A550/A560/A580, they use have 2 types of Live View, one is the Sony Quick AF Live View (Using Phase Detection the same low resolution capturing sensor) and another one the Manual Focus LV which is the traditional conventional Live View style which uses the Main sensor and display with maximum resolution and able to magnify the pictures for checking the sharpness BUT no contrast detection.

On A33/A55 which is the new DSLT had break through the original phase detection system by using the translucent/transparent mirror so that the light can split on both the Phase Detection and the camera sensor at the SAME time so it can do phase detection with crisp resolution live view and EVF, because it was directly access the light through the sensor, the camera it self can do like what the rivals Live View do BUT with really fast Phase Detect autofocus even in very fast burst rate and focusing speed and, also high resolution magnification  *(i dont get the last part, we can do burst while zoomed in meh??)lol, i get it, i not suppose to stuck all the sentence in one meaning. added a comma
(correct me if I'm wrong)
*
*wingster, i help u do some minor correction to avoid misunderstanding smile.gif, btw QLV is a capturing sensor, not the AF sensor or phasedetect sensor. the phasedetect sensor sit below the mirror box there. always been there. all other SLR design are base on this ideal by minolta.
*hmmm i think i edited too much sweat.gif

Haha thanks for correction , I'm actually dunno how to explain it well and something that still figure it out xD

But just 1 question that the Quick LV visual (the sensor) doesn't it with together with the Phase Detection sensor as well (on the top)?
*
well, Albnok explained. but i think u are confused with that capturing sensor. IF (i say IF) the AF rely on that secondary capturing sensor, then its a Contrast Detect AF already~ wink.gif it wont be Phase detect. Sony designed QuickLV so that, able to project image to the LCD and still able to use the Phase Detection in realtime. unlike others which has to close down the mirror in order for the phasedetection to work in split second, many nikon/canon user do not like LV, i)because of the delay, ii)many complained bad focus in lowlight(not enough time to hunt/lock). hence, when me meet other N/C 'fanboy', they will go around and talk about how real/Pro photographer uses OVF, not LV (or EVF) sucks... they just dont know what they are really missing, the Quick LV.

so when u on QLV, the phasedetect sensor, and the top secondary capturing sensor are both activated, the top sensor is calibrated so that it fits nicely to view as like the OVF and share the same AF points.

BUT there is a Major diff when using LV and OVF, is the Metering sensor.

in OVF, it uses the 40-segment honeycomb metering sensor.
in LV, it uses the capturing sensor 1200-zone evaluative segment, which, is far better in giving more accurate metering. hence, Sony QLV is in fact, far more advance and reliable then N/C smile.gif



cplow1, freddy manson: when added strobe (flash) in a photography, ur photo metering now is divide into 2 area.

i. the foreground,... aka the subject, usually being lit up by the flash....
ii. the background,... aka ambiance light...

the strobe, usually controls the foreground metering.... while, its the camera setting (the Exposure Triangle) that controls the background metering. how people play with highkey and lowkey must understand these key.

boosting up ur ISO, does brighten up the Background, hence why in early days of A300, a lot people love Canon's banquet shots, because they shoot at iso1600, where they have brighter (or same) background/ambiance light as the foreground, while those iso400 shooter(aka A300) will have 'dark' background. if u have A550, go iso1600 all the way, and u will definately felt like canon effect smile.gif


Added on October 7, 2010, 12:28 pmanother way to add brightness to the background is to use, SlowSnyc Flash (or SL flash, or BL flash whatever other company name them)....

the metering will run base on the ambiance light, run the setting on ambiance metering, giving u slower shutterspeed(on low iso) so it will have enough time (slow shutter) to capture the backlight ambiance... but most people would like to avoid this, because it might cause a lot of ghosting image, and imbalance WB issue later on.

before everyshot, i adjust my flash knowing where it will lit. i use all angle even 140degree(backwards)



bouncing flash is like bouncing a BALL.

when the ball fall at 90degree, where will the ball bounce to?
when the ball fall at 60degree, where will the ball bounce to?
when the ball fall at 45degree, where will the ball bounce to?

when ur flash is bounce at 90degree, the light will always come down at "????" degree... hence lighting on that "area"

when ur flash is bounced at 60 degree, judging on the ceiling height, where will the bounce light land? and that landed area, is the lit area of the flash.

so, now, in practical, what degree to use, is judge by the distance u going to shoot, u will not bounce 90degree if ur subject is 8 meter away.... because it will only lit the area u are standing, or the flash will FIRE max hoping some 'leak light' will reach 8 meter away to brighten ur 'subject' @.@

if u were shooting at high angle (camera tilt downward), then ur flash might need to bounce 'backwards, or 90degree UP to lit ur subject when they are 1-2 meter near

Well said ieR!

cplow1: Harshness is due to a small light surface at close range. If you use a higher ISO and wider aperture, you let in more ambient light, making harsh light less obvious.

Also, for shooting telephoto, just go direct. The light would've spread out so much already that any harshness is not obvious.
*
TQ. smile.gif

cplow1: well. the harshness only happen if u have super reflective skin surface. else, its really nice... direct flash is no different from WL direct from another angle, but no ppl call it harsh~ hmm.gif

the wide panel in fact, is better then bare flash, because the widepanel spread the light so much, it actually bounce everywhere that bring more directional light to ur group photo tongue.gif

seriously, that link is more misleading then it teaches... bounce flash is depending on the distant u and subject... but the link uses a static subject at the same distant, it will mislead people thinking 90degree is best light. summore its missing bounce card for front fill tongue.gif

@Albnok & ieR : "1200-zone evaluative segment"

So far I know thats from the spot metering doesn't it? I can't tell the difference between conventional OVF and Sony LV in terms of sensor accuracy :/

40-segment Multi Segment, Center-weighted, Spot; (1200 zone evaluative metering in Live View)
*
ahhh, u are now even more confused. LOL.

metering has 3 mode.
i) multi metering (or all zone metering, or wide metering, other brand will name it differently but its the same)
ii) center weighted metering (this take a small area of the middle zone, best for portraiture of subject in the middle where it will ignore strong backlight around the corners)
iii) spot metering (take 1 segment only, of ur AF point, this is the only metering that can move around... logically, wide/multi mean all segment, it can move, center weighted is CENTER weighted, so Spot is the only metering can move around and meter according to the selected point.)

sony uses 40 "honey comb shape" boxes, to evaluate the exposure. how? (actually i dunno the actual value) it take reading from each of the 40 segment, and get the AVERAGE(balanced EV) out of it, and calculate the setting to shoot.

it works the same way with 1200 zone metering. just that, with more 'zone/segment' the averaged unit is more accurate then just 40 segment. hence, when u shoot are with light source (light bulb) the 40segment sometimes will goes underexpose to control the light thinking it was overexposed. while 1200zone will detect more accurate metering by having more meter to average, it will have more balanced because it calculate better of how much did the lightsource overexposed the segment. but the weakness of the 40segment is also due to it uses penta mirror, if its penta prism, i believe its much better and the prism are brighter then the mirror.

go and try it out smile.gif

conventional OVF is just OVF.
sony "quick" LV is diff from conventional LV. But, sony MF LV check is actually, same as conventional LV (or works the same way) jsut that, it wont try to AF when the mirror comes down.

how QuickLV focus is, the Mirror stay there like in OVF Mode. the mirror box is untouch or unaltered. it still reflect the image upward to the OVF area.... its just the OVF area of A300 (or any model that has QLV) is using Penta Mirror instead of Penta Prism, you will notice there model has much smaller OVF. the penta mirror is tilted slightly, reflecting the image from the Main Mirror below, into the QLV capturing sensor.
now, since the mirror box is unaltered, mean the AF module is still intact and able to still uses Phase Detection. hence with QLV, u still get fast AF then other conventional that, they need to Lift up the Main mirror, making the AF module below unable to work.

yo, i advise A560/580 no matter what. its a A550 replacement.

i) 15 af point
ii) HELL LOT faster AF detection and lock
iii) i heard from insider who tested A55 for a whole week, it focus marvelous in Pub, so i guess the A560/80 has better more sensitive night shooting.

as a photographer, u know those top 3 thing is more important then iso, megapixel or grip.

it is soft when u zoom in to 100% (friend send me samples) at F3.5, but the sharpness is okay at F5.6 and better at F8.

but if u resize the 10mp photo to 50% (5mp is still huge photo), it is tack sharp smile.gif
