16-35mm f/4. I took the wrong lens for this as I thought I'd be able to get some cool ultra-wide angle shots of the wind tunnel and it just wasn't the way. I needed a zoom but f/4 was too slow as to avoid subject blur I needed to shoot at 1/500s and that meant up to ISO 20,000. The Sigma 24-70/2.8 would have been a better choice, or f/2 primes and put up with changes.
