With my Sony A7 full frame camera system now, I have got 2.5 lenses which I can use.
A kit lens 28-70mm f3.5-5.6, nice daytime performance but wired shakes often appears. I will talk about it days later.
A pancake lens from APS-C E-Mount system, 16mm f2.8. Disattached its rear shell to get full image circle for full frame sensor, however, it barely covers it. So it’s a 0.5.
Of course, and a 50mm f1.2 nikkor manual lens. Today’s pics only use this one.
