Some first impressions of the 50mm f/1.4 lens on a NEX-5 using the adapter. First and formost, the lens weighs much more than the kit 16-55mm. Seriously, even without the adapter it feels twice as heavy. The Kit lens is almost flimsy in comparison.
There is no autofocus, but that was to be expected. The adapter supports it but the lens doesn’t. Since stabilization is done in the NEX lenses, it’s missing as well. The lens is so fast, though, that you would never miss it.
Peaking makes focusing much much easier, but it’s still a challenge. The depth of field at objects three to six feet away is so apparent that focusing on a specific part of the object is important. I haven’t had a chance to use it in too many environments, but where I have it’s performed very well.
It is noticeably sharper than the kit lens too. One of my biggest gripes about my NEX was how soft the images came out. It was definitely caused by the sub par lens offerings from Sony.
Moving forward, my biggest concern it focus. With no autofocus to assist, snapping quick pictures is going to be tough.
