i think new 16-50 f2.8 also have same features..
just wonder if the lens itself support dmf.. why still require from body..
like the 18-135 not fully support..

AFAIK if lens no DMF only than use from body...

but even have in body.. the 'old' SAM still not support... end up to use the lens switch..

Damn. Im waiting for my A57M. Stock is coming. Didn't tried this feature before.

Or maybe firmware update can help?

View Page 117, DMF. Not sure is the forumers are correct or the user manual is correct.

whats the problem jimmy?

-_____- errrr not really likethat... come TT la tomolo at KL central 1pm~ lol

its a logical issue u have to think a bit.
DMF is there FULL TIME... u can refocus anytime, its the body's AF system that will "dont understand your are Manual Focusing" and go refocus after u play with DMF... coz DMF once u let go, the clutch activate back to AF mode...
u need the camera to lock, and 'deactivate refocusing'.... so it wont kacau your focusing during DMF

hey jimmy give to me la 18-135 like that lol..
actually i no use the DMF.. so i won't care much.. i just play with the sensor only to make it focus right.. easy AF..

even though A77 has DMF in the body.. most of it only can be used with normal screw driven lens only...

ever since have the peaking mode.. i more prefer to toggle AF/MF.. so i can use with all lens lol.. no double standard..

Hi all Sony A57 users, do u find out u can switch to the middle between AF and MF located on body? Does it means DMF? It does not do autofocus anyway.

ya, so half press the shutter and adjust the focus. Nice lens, pretty good in macro at full zoom. This lens is poisonous!

Added on November 21, 2012, 9:56 pmbut can your A57 body AF MF switch set to the middle(between AF&MF)? Or mine got problem?

dear jimmyyap03, A57 do not have DMF

only A100, A700, A900, A850, A77, A99 has DMF

and DMF also available "in"

Crop lens:
SAL1650 SSM
SAL18135 SAM

and all SEL (Emount) lens.

and FF SSM lens

but my fanboi fren said sony camera take picture suck vs other well known brand~

if u can spare a little more, yea, jump on the A57, the image quality is slight better in term of lowlight, body feel also more solid (bigger compare to the A3 series).

as for lens, there are currently 2 packages, one with the shorter zoom lens, 18-55 (which is a lot cheaper) and the longer zoom lens, 18-135 (which cost a little more around 700-800)...

my advise is go for the 18135, it is very sharp lens, and very friendly zoom range.

as for "wide angle" topic, first thing you need to know is that you are on a Crop sensor, anything that is larger then 24mm is consider wide angle on crop. and 16mm vs 18mm on crop has not much different... unless u are talking bout "Ultra Wide Angle" UWA, which should range from 10-18 in crop factor. but it will cost u another 2k+ just for that lens. so the advise is still try to shoot with the kitlens (1855 or 18135) and try to understand more how does the lens work,... until then, u will know how to pick the next lens to purchase.

A 18-135mm user here. If u shoot a very wide range, and doesn't care a lot for img quality, go for 250/200mm ones. 135mm isn't quite enough for me(I can use clear image zoom to reach it), but damn. I love to use the DMF function, and use a lot.(Nearly break my fren focus ring, its not a DMF lens >.<) Not sure if half press the shutter & turn the focus ring will do any harm? A57 body doesn't support DMF.

yeahlor! spend so much but still not giving DMF DMF! NEX also don't have DMF!!!    

ARGGGGHHHHHHHH    

Mengkiat, darkholedevil, shuddap u two pro body users, shoo shoo...

jimmy, All, Allll Sony e mount(nex) lens are DMF... So no need body dmf.. they trolling only..
