with such shallow dof manual focusing is pretty useful - the camera doesn't always know what you're aiming for. getting it just wrong would things way off.
forpetessake: It looks longer and heavier than 28-70/2.8 FF lens. Did Sigma simply glue those 4 elements from SpeedBooster to the 28-70 lens and cut the long end due to vignetting?
Designing a new lens takes more than a couple of weeks... This lens will have been planned for a year at least and the SB is what - 2 or 3mths in the wild?
FTW: 850$ for a 10-18 and only F4. they are kiddding. So, again the lens one waits for will be out of price for the normal user. The 16-50 seems ok to me, at least. So, I will stick to the Tokina 12-24 F4 with adapter. She performs great on NEX-7, despite being much bigger and half the price of this Sony lens. Seems to me that the NEX will get pocketable with the 16-50, was great time that Sony moved there backs and made something.
+1 for Tokina 12-24. At F4 16mm mine is much brighter than the SEL16mm 2.8@F4 - weird since it has so many more air-to-glass surfaces. Could even be brighter than this new lens.
In reviews - the Tokina pretty much neck-to-neck with the Nikon - so it's perhaps a bit more than a substitute!
abi170845: I've been waiting for the 10mm zoom!finally! F4 but it has inbody image stabi for the nex7? 850 RRP, I hope the street price is lower, just like my fav 10mm EFS, it was about the same price when it came out. but now I can get a mint second hand for about 520 U.S
I knew the 10-18mm was coming, but I didn't want to miss the whole summer without an ultra-wide lens for my NEX C3.
Bought the Tokina 12-24 instead (Nikon G mount). It's pretty large, but manual focus is the norm at this focal range. It even has better/comparable performance to the Sony Alpha lens. It's pretty awesome - so sharp, contrasty, sumptuous colours, v. useful range etc..
Very relieved I did - since it's less than half the price of this e-mount!
