Hi all:
I just received Lens Turbo II PK-NEX from Taobao last week and ordered a NEX-6 along with it. I would like to share some thoughts for those who is interested.
The adapter itself is hefty but good quality, somewhere between Kipon and Voigtlander. When mounted on NEX-6, it is very stable. The weight itself is 175g plus 345g of NEX-6. Total weight is 520g. Not exactly light but not much weight saving compared to K-30/K-50 given K-30/K-50 has good viewfinder and AF.
Nevertheless, the balance is good and focal length and aperture is multipled by around 0.72X ( MAX aperture is limited to F1.0 no matter how bright original lens is). The DOF is thin with Lens Turbo II and focus peaking doesn't always work but EVF with 10X magnification helps a lot. Under bright sun, GXR b/w mode or K-3 optical viewfinder is definitely better. But overall, for the price, I am happy with the purchase.
Since this week's is starting of raining reason accompanied by busy schedule, I was only able to take few snapshots using three lenses:
K 24mm F/2.8
FA 20-35mm F/4
Ricoh 55mm F/1.2
NEX-6 setting is standard, +1,+1,+1, +0.3EV, AWB, SOOC fine JPEG and resized to 1MP using lightroom(standard sharpen for screen) without any additional tweaking. Uncropped as I think people will be interested in corner performance. I will post more samples with other lens like FA limiteds in the next few weeks.
