ownership:I own this lens
compared to:SAL1650 16-50 F/2.8
Sony 24mm F/2
price paid:330 USD (used)
positive:Widest F/1.4 AF you can get for APS-C
Good for low light
Pretty sharp in the center even wide open
reasonably lightweight
negative:Noisy AF motor - just forget it for onboard audio for video shooting.
No AF/MF switch
Focus ring makes noise even in MF mode
APS-C only
NO HSM in Sony mount! Why?
comment:The widest autofocus lens you can buy that opens up to F/1.4. Next is the Sigma 20mm F/1.8, then the 24mm F/1.8. All three (for me) are far inferior to the Sony 24mm F/2. I use this lens to shoot low light MF video with the A77. For shooting indoor kids pictures and movies I feel it's a tad too "tele" for my purposes with the A77. Since the video crop factor with that body is an effective 1.86, this is 55mm equivalent in video mode. 45mm effective for pictures is much better.
This is a great all around lens especially for the money, but I will sell this and stick with the Sony 24/2 and 16-50/2.8. Colors IMO are a tad on the flat/warm side; definitely not as nice as Minolta colors.

If Sony would release an updated version with HSM focusing and FF compatibility it would FLY off the shelves.
