Hummingbird

 I popped over to Middle Creek in the week to try out a new focus range limiting feature in a new firmware update for my Nikon Z8. Most telephoto lenses have a switch that limits  the range of the lens mechanical movement which allows faster focussing, this is typically something like 6M to Infinity. In the latest Z8 firmware Nikon has added a software limit so you can set a lower focus point and a high focus point. I wanted to try for some Hummingbirds at the nectar feeders at the Visitor Center. I focussed on the feeder at around 5M then set the lower limit to 4.8M and the high limit to 5.2M. As the Hummers are lightning fast it's easy to misplace the focus point so rather than have the telephoto snap onto the background which is a lot of mechanical travel for the focussing mechanism to get back to the bird it only has to travel with the set range. It works very well, I will use it a lot at my backyard feeder setup.
