The Blue IR/NDVI Lens Filter from Kolari Vision transmits both blue and IR, making it ideal for NDVI crop analysis applications, allowing an NDVI to be generated from a single image using the blue and red channels of the image. This filter is also handy for landscape photography, as it produces a similar effect to the 590nm after a channel swap, right out of the camera.

A: The Canon RF 600mm f/4L IS USM Lens would be a great lens to use for baseball photography. One thing I will state is it may depend on the size of the field as to where you may need to be positioned for the best image due to the lens' magnification. You may need to be further back if you are on a small field, but this would be a great option for large fields and for capturing intimate, up-close moments of players in action.
