more expensive da better  rclxms.gif
lenses are expensive because of the glasses/elements used , different calculation (optics) , more/less coatings and thousands more to consider. thats why its expensive and good.

i'd prefer the minolta/sony 24-105 f/3.5-4.5, seems as sharp as the 16105 with slightly larger aperture at end focal. the minolta 28-135 is also one of the best, some say a hidden G lens  laugh.gif
A standing wave ultrasonic motor utilizes high-frequency voltage to extend and turn the Piezoelectric (Piezoceramic) element, thus moving the entire element in a standing wave movement. The metal tip is the contact point of the element to the rotor, and moves in an elliptic motion from the swiveling motion of the moving element, and the friction from this motion turns the rotor. Standing wave ultrasonic motors have the distinct advantage of being smaller than their traveling wave counterparts, and therefore allow a more compact SLR lens size.

not really.

the new nonac 70-200 f2.8 IS II cost about twice the one without IS, and almost 1.5 times more expensive than our 70-200G.

does it mean its much much more superiorly optically better than its predecessor or our sony lens?

ok now i got the picture why it cost more..
thanks for enlighten me up!

btw.. it there any advantage if the lens using bigger filter size?

there's more disadvantage than advantages i can think off..

more chances of vignetting..more expensive filters...

lens require bigger filter size is because they need a bigger body to fit all the elements, AF motor and the image stabilisation mechanism..which makes them more heavier and bulky...

16105 is really sharp.. when I had CZ 1680, I think I just waste my money. I can get 95% of the CZ sharpness with longer zoom

canon means canon la, apasal nonac la, nicknack la, tictac la... doh.gif

image stabilization is a technology which costs an arm an a leg, especially when the fact is that they DO work.. considering the size, which is similar to that from 70-200G, WITH IS in the lens, i say that is a pretty well miniaturization of some pretty nifty stuff there. some canon users might use the fact that canon L lenses openly say that their lenses are weather sealed, and myself would take that as a pretty good assurance to use it in the toughest condition mother nature can throw at me without a flinch.. would i do the same with SAL 70-200G? not that i say it cant, we have users who have tried and tested it out on the open dessert, rallies etc... but i'd do that with my own lens with a pinch of salt. their IS consists of different modes of IS, where when used in different scenarios, does give a better advantage over those who doesn't have the option to choose. its all about the details, not only optics are solely taken into consideration.

susah to compare between different brands/company sweat.gif
but for that price it should be better than its predecessor cool2.gif . if not the user would bising and mogok laugh.gif

8tvt : bigger filter look more pro good laugh.gif . but if too big = more $$. also CPL polarization doesnt work well.

this one has 112mm filter sweat.gif

IS is more expensive to implement in lenses with larger glass elements as the IS motor will have to physically move bigger and heavier glass. That is one reason why it is more expensive. Sony's SteadyShot moves the camera's sensor around to achieve the stabilization, so the specification of the stabilization motor is fixed. You only buy ONE stabilization and use for ALL lenses.... in Nikon & Canon, you need to buy ONE stabilization for EACH lens....

shootkk, gotta love your way of saying this. laugh.gif

kopitiam, don't think you will be able to get stabilization with M42 lenses, unless you couple it with the AF confirmation chip adapter (not sure about this also). But yes, all minolta af lenses will benefit from the same SteadyShot stabilization as well. rclxm9.gif

i do wish sony gives the option of lens stabilization in 70-200 f2.8 lens

then at least we can use a mixture (in-lens stabalization on & in-body stabilization off)
