Q: 4. I live in an apartment , its tiled floor .The people who live in the down floor complaining me that my drum kit noice is to loud . If I buy this Auralex Hover Mat will I be able to reduce the sound goes to the lower floor ?

A: Hi Ramesh, The Hovermat will help reduce the noise of your kick pedal, but it will not diminish anything that is not directly being transferred into the ground (such as toms, cymbals, snare). Sound is like water, it travels in every direction and gets through every gap. If you covered your entire rooms floor in a layer of something, that would diminish the noise traveling through the floor.

Q: 8. I see aperture ring and numbers in the product image. If this was used on D7200, does the camera recognize the aperture selected on the ring? And how do the 1/3 aperture stops work?

A: The aperture selection on the ZEISS Milvus ZF.2 lenses can be done using the ring on the lens barrel, or via the sub-command dial on the camera. This choice needs to be made in the set-up menu on the camera (refer to the D7200 user manual for more information). When the aperture ring on the lens is chosen, the aperture is changed in 1/2 stop increments. When the aperture is controlled via the camera using the sub-command dial, then the aperture can be controlled in 1/3 stop increments. When using this method, the aperture on the lens should be set to the lowest level until it clicks into place. Otherwise you will see EE readings in the camera menu.
