First of all, which Urth adapter did you get? The one without the lens inside won’t achieve focus at infinity as the lens sits too far from the sensor.

 

You need to shoot in full manual and either guesstimate the exposure, shoot a test frame and adjust from there or use liveview to judge the exposure, I think. I haven’t played around with adapted lenses on F-mount, myself, and there might be some way to use stop-down metering on the D610.

Most of the M42 adapters I've seen don't have the necessary linkage, either mechanical or electronic, to transmit aperture data to the camera. So, if that's the case with your adapter, you'll need to use stop down metering.

Replied to your other post

The exchange between lenses and cameras happen by electric signals and brand specific protocols, therefore, while an adapter allows you to mount an « alien » lens on a camera, no information exchange occurs between the two pieces of hardware (lens and camera)

The most important to do is to set the camera to M(anual).

Setting the lens and/or camera to M is not necessary (as no information exchange happens)

For setting the aperture, use the ring on the lens.
For setting the shutterspeed, dial it in on the camera. Same for the setting of the (Auto) ISO

Hope this helps
