My 16105 focuses very fast at 16mm, but slows down at 105. Izzit normal?

motor in lens is faster than motor in body?

as long the person u want to focus is more than 5 meters, just put it into infinity & shoot away

or use smaller aperture, really no need to focus with the 8mm samyang

a bit fortunate to get this shot with the nobody in sight.

or you can use ND400 filter with low shutter speed to eliminate those passerby

that would be a wrong way to do it. that case, your near subjects will not be sharp. using hyperfocal, setting it to focus at 1 meter at f/4, everything from a few inches in front of the lens all the way to infinity will be in focus

need to play more with ier's fishy

if you are asking about the SSM/USM in lenses,then YES,they are faster & more quiet than screw driven lenses. For SAM,I feel the AF speed is same or sometimes lower than screw-driven Sometimes depends on the lens also,my tamron 17-50 f2.8 is much faster than SAL1870

I found that her right cheek was very weird lighting problem or my eyes problem?

btw,was that another girl's shoulder near her tummy?

all lens when reach further extend (zoom in) will slowdown in af. no matter ssm or magic motor.

hmmm...nowadays agency cut cost?

yeah...the someones shoulders there

but the key point is, 8mm crop is wider then 16 ff... that is the fun in the 8mm

codyx: that girl pweety la...

i'd love to see sony make something like canon's 8-14mm f/4 though.

Agnes Lim is pretty.

yup yup. too bad no 8mm fisheye for FF

Yup..i made my choice d..just asking opinion only..scare later gt same price and better lens..xD

I m not bug lover..but i like to do closeup..

So worth getting?..my main usage is for portrait and closeup..and sharpness!!!!..

if too sharp later can see all the face imperfections

how much is the lenses u gona get ??
