Q: 1. Hello,I am concerned about how a person determines if a subject is in focus or not. Will my focusing green dot on my Nikon D610 work with this lens? Do I have to look at the image and determine focus by the picture quality. I have tried magnifying eyepieces and my eyesight will not allow me to use them.Thanks in advance.Bill

A: When the lens is stopped down the dot indicating that focus is achieved works fine. When working at a shallow depth of field, live view or a zacuto z pro finder helps with focus. If using live view a helpful hint I found on the internet is to program the center button of the multiselector (option f2 in the custom settings on a D-810 so that live view will immediately go to zoom mode when this button is pushed when you're in live view. This button can also be programed to zoom during playback to quickly check focus. You can program it for 50%, 100%, or200% magnification and it zooms centered on the site of your focus point. On a sunny day a hoodman is very useful. It's much smaller than a zacuto and can be quickly placed over the review screen to check exposure or focus in the sun when you can't see the liveview screen well. If relieing on the in camera focus dot for focusing with a narrow depth of field, there is quite a distance that the lens focus ring can be moved and yet still indicate that the camera thinks you are in focus. I did some test shots and I found that sometimes even though I thought I turned the focus ring until it was about in the center of where focus was indicated when coming into and out of focus as the ring was turned, the picture sometimes was still slightly out of focus. I found that if I started focusing in front of my desired site and turned the focus ring until the camera just indicated in focus I often achieved good focus, but when I began focusing behind the subject and turned the focus ring until the camera indicated in focus then the image was always fuzzy. This also happens with my other camera, a D700.
