well, performance wise, G and SSM's Zeiss does get the best out of top AF system(it does contribute to lowlight shooting, example of the A700's F2.8 sensor). and A900 will pushes the 70200G SSM to the limit (even better sensor to grab accuracy, and dual Bionz for processing and speed.

so, say, A2/3 series, they dont have F2.8 sensor (special sensor), and older sensor, it might not performce at best at lowlight. A550 has the newer AFsensor but not F2.8, but many review quote it's as good as F2.8 at lowlight. i have not tested it, so i have no comment.

i'd just say, the newer ur system/body/AFsystem, it will greatly benefit it.

for IQ wise, its very debateable... coz each lens has diff characteristic, and diff sweet spot, and also body dependent (FF and BF issue)


ksano: i wont say the IQ is the same FF lens on FF or APS-C. standard FF lens are knowns to have softer corner(no comment on the premuim FF lens),... that why on APS-C... they dont see the corner because they only capture the centre area of the FF lens, which is the sharpest zone. hence, many people will say that APS-C has sharper IQ then FF.

and lugia the A450, i wont mind, coz the price is about the same as A330twinkit...

(A330 has LV, A450 doesnt, but greater iso, DRO, and auto HDR, 7fps then A330)... how to compare?

wait a little longer, the EVIL system will be out soon... it will has the IQ close to DSLR... better clarity to M4/3rd due to larger sensor. and FullHD video with AF!, u can just snap the video, go back and cut out the scene u like since fullHD is 1920x1080, that is big resolution. u can grab a mount to use Amount lens..

but i am praying, at least, give a flash hotshoe!~~~


and WX1 or similiar model are great alternative if u are not those bokeh freaks or high clean iso freaks. they do very well as a compact camera.


m4/3rd lens arent any cheap iether. and limited selections.


lugia (and someone i lazy read back):
when comparing 1855 and 1870, definately the AF speed are taken in account, so is SAM vs body motor. i take it the A300 AI/chip arent optimise for lens motor... coz it works really slow with 70200G too (played with friend's A200+70200G, slow also) but i believe, (have no tested, but it seem the A330 with SAM are pretty fast on my hand) SAM is generation dependent, anything after A900 would go faster? (since 70200G is really fast on A900)

the SAM motor, main reason is being real QUIET. that helps a lot in movie recordings. (SAM are prepare for the future video bodies...)
some of my friend tested, it seem on A550, AF-C works marvelously better with SAM lens. no comment.

and lugia.... MF LV check is not excately LV i guess(i dont see it taht way, the purpose of it wasnt LV at all)... the new model they call it MFcheck (i think, they removed the letter LV, LOL)... instead knowing there is a LV but u have to MF, might as well ignore it and pretend it doesnt exist LOL (joking)... but i agree with ur statement, A450 has LV, but not QLV. (btw, the fast AF LV is called QLV, quick live view)

@.@ wow,... this i really need to hear... how a UWA lens with short focus gear, is slow.... they have sooo much DOF, its even easy to use manual focus....

SP90 available in canon nikon and sony mount.

Sony doesnt has a Sony Alpha Lens 90mm.

u can easily sell it and buys a nikon mount on by topping like rm100... they are pretty cheap lens... anyway, there are a lot nikon selling the SP90 too... lol

lugiamcg: well, AF speed, is influence by SOOOOoo many factor that, is so subjective. there is NO way to Generalize ALL lens characteristic. each lens has diff gearing, diff length, diff IF or EF design, diff gear size, and lot more.... even technology plays a factor, and camera body.

when u compare direct 1 point to another point, like SSM vs SAM or SAM vs body motor, it's easy to compare because we neglect the gearing possibility...

A450 cant 4fps with MF LV check. it cant, the mirror flip cant flip that fast~ unless it has mirror lock up features. i cant comment, i dont own a A450. however so, it has a LV but its for MFLVcheck, which is not practical because it does not activate AF.

Fighteden: depend on ur NEEDS, but if not for mobility, u are making a big mistake letting go the A300! A330 does not have a battery grip option (i prefer to call it Vgrip as Vertical Grip (or vertical orientation grip)). sony was thinking that Entry level is pure entry (family shooter), u dont need fancy tools to make it look big... u wan big, go BIG... like A4xx,5xxx,7xx,8xx,and 9xx

nope... A700 has all of A550 + extra F2.8 sensor. so it triple the sensitivity. but new tech AF is always more sensitive/accurate/smarter

the vertical and horizontal sensor, we call it cross sensor, cross as a '+' shape. all models has cross sensor for the centre AF point (sony calls it focus area =.=)

i didnt generalize 70200G as slow lens... i said it was slow on a A200, hence, yea, it could be body dependent too... but i wont say weaker, it did lock on first focus, it did not hunt, but it felt bout a little faster then 55-200 @.@ hence, i judge is on A200 is slow?

seriously, i cant really judge, might be the sensor itself, or the body tells the SSM to go slow, the optimum of the AF sensor speed? it was kinda slow on A200,... but i heard from a friend of A900, he said it was really really fast... i have no comment, unless someone with A200 and A900 with 70200G can do a control test and tell us the result...

the major noticeable thing is, its total silent... u keep asking urself, is the lens focusing? or not?

This post has been edited by ieR: Mar 5 2010, 11:07 PM

actually no need so such find 70200, any G lens can test... or CZ SSM 2470. anyone here has SSM lens and A2 and A7 body? got diff in speed?

erm well to comfirm it, u have to use an SSM with control environment, said a well lit room. my 50mm focus pretty well, due to assist light from my F58.

hkhk, more or less the same,... all suffer the same problem... they also suffer the same lowlight focusing problem... lucky D90 has the AF assist illumination else like D60 hunting only... every camera faces the same issue... even in speed. but the A550 shows a leap in technology in the AF system... not to say to the iso breakthrough... the AF, some say, better then D7(also equip with latest canon AF system!). no comment. we really can see sony is going all out. others should be worried.

albnok: opps, my mistake, i thought they remove the word LV from the MFLVcheck... instead they lengthen it

so, A550 wasnt excately 'PRO' sensor like 7D, but its because 7D is so complicated and 'messedup?' that it give inconsistent/inaccuracy result?, hence, A550 how come 'cheated'(found) its way to 7D's backside? well, result is result, A550 give better result in the end, right?(for now, until 7D fixes their problem thats it?) (i tot practical result is more important then spec, rite?)

A550 is a little below 7D in DxO iso points. but 550D is Same as A550. (given A550 is cheaper,.. and 550D has higher megapixel)

in the future, u wanted to buy model like A550 and A7xx, or FF series. because it has better ISO (far much better) and the speed u may need.

a Vgrip is a very subjective needs. i have shoot over 10k pics of vertical orientation (My current shutter is 38k+), non is with Vgrip (i dont have one iether... , but i have around 1-2k might not be horinzontally equal thou , but i can always re-align with photoshop and loses 2-7% of border, depend how sengek, so it doesnt bother me)

i remember an old story, happen to me (real story)... i was studying in this college, where they have a library even smaller then my bedroom... all the student were complaining how small it is, how little books there is to read... how limited the selections.

one day, the dean got pissed off because of our constant nagging and complaints... and gathered everyone to the hall.

she said, she knows the library are small, limited book... but she herself hand picked the books to put on the shelfs... she knows the book very well that she only picked the books that are good to us, and needed by us, and enough to cover what we needed. although it is small... can we really read everything in a year?

i nodded in agreement. to think of the ironic of it,... now... sony might has small range of lens... sony hand picked the best required lens to market. they knows the lens very well that they hand picked the lens that are really good for us, and needed by the field and enough to cover what we needed. although small range, can we actual owns all the lens? and the best thing of all, sony got carlzeiss to help make the top piece of sony's gems.

IwanAGP:
the grip is pretty small, some ppl likes it, most dont. but everyone lives with it.
the AElock, do u know what is it? 70% of shooter here hardly ever use that button. u can always use M to overcome it.
2.5fps.... 90% of people here hardly need 5 frame recorded in 1 sec.
lens. we have more then enough to cover the most basic lens, then tamron and sigma does make lens for A mount, and tokina is jumping into sony bandwagon
batt life. i have no comment, but i always leave house with batt fully charged. and buying an extra batt is not that expensive.

i hope this convinces u...

NBTD... shoot something to clear up some 'body driven motor' issue.



ohya, shoot with tamron 1750F2.8.exif: 0.6sec, F4, autoiso400. no flash fired... a table lamp from the right side.

marvelous! just the 2 stupid spotlight thou... if u could somehow photoshop them under a little.

i got the meaning, and it's pretty nice... just the color could do a little editing...

braindead_fr3ak: WOW! nice!!!!!!!!!!!!!!!! btw, the extreme top right of the pic (the wall) its a little, not 'pretty' or balance, the hinge one tall one short... and the 'nails' looking thing spoiled it. but the bliss from the picture... wow! i give 9.0 out of 10! (the 1 point due to the wall hinge and nails thingie)

braindead_fr3ak: keeping it simple, and simple minded of me...

i just love, how the wall is there, even thou it's plain... let it be plain or full of graffiti, a Not many photographers shoots wall.
i also love the way the lighting, natural or cause by ur vigneting... it still felt, like a room... a room dont always have to be Fully Lit. the partial lighting works well.
i love how there are human subject there, although, they are just props.
i loves the wooden floor....a lot, because it is so perfectly imperfect wooden floor. (instead of capturing a 'pattern' of perfect floor, where everyone does it all the time)
i love the angle, of all angle, u can shoot straight, vertical, but no, u picked a nice angle to represent it.

i Dont think of sorts of wild imagination of what stories the photo tell. to me, it's a simple art, and it's beautiful.

aiyo... i dont see it as simple... LOL i see it as a good photo that have nice element (that u think simple coz i said the word simple minded) LOL...

'
LOL, if can bulk, i'd bulk 50unit of 70200G, (1 unit = 6699-1674.75(25%) = 5024.25, i think the cheapest 70200'G' in history... lol) and sell it at 5200, still untung damn a lot... wait... 50unit x 175 = 8750! wow, a new A900~... ok, i am talking non sense...

i think he will have bigger problem then that... one from east, the other at west... LOL

give another 5% spacing on top, then perfect~ but it's already nice on its on.
