Exposure metering and focus confirmation work. I tend to use it in manual mode but aperture priority works also. Most of my use with this lens is on a tripod so liveview (exposure simulation) works well. I manually focus using liveview, adjust shutter speed and shoot. The adapter does not use a set screw so changing it out is straight forward.
In order for the exposure to work, does the chip need to be installed on the adapter, I know that there are two options with and without chip (For AF confirmation). Will exposure work without the chip?
