NDP NE1 on the Hexar RF and Voigtlander 90mm f/2.8 [Kodak Gold 200]

I wanted a 90mm for the occasional longer reach and decided on the Voigtlander over the Hexar counterpart. Its definitely a lens that does it's job but looking back now, I'd definitely pick the Leica 90mm f/2 V1 from the 1960s because of its characteristics. Nonetheless, this is a very compact lens and something easy to carry around. What better way to test it out and the Hexar RF's speed than shooting some planes?
