>>4007466You can get a 50-300mm f4.5 AIS constant aperture zoom lens from Nikon for less than $350.00 or less on Ebay.
It is the perfect budget full frame lens for video and for photo. Plus it is a 5x zoom lens that is relatively rare even for modern zoom lenses.
For some reason no one know knows about this lens and next to nothing has been posted on youtube.
+ something like a Canon EF 28-300mm f/3.5-5.6L will cost you $2500 to buy new and it is not even constant aperture.
