Hello! Looking forward for an upgrade from my 70-200L Canon EF lens onto something a little bit bigger. The reason? Even 200mm on my cropped 7d isn't enough to reach some points at my home airport. Larger lenses, on the other hand, do (https://www.jetphotos.com/photo/10398513 — a picture from my friend with a 400mm lens), but right now I am short on money to afford myself a Canon EF 100-400. So I am looking to buy Canon 2x extender of the first or second generation and use it with an already-owned 70-200 f/4.
Did anybody here use it? Is it worth buying? Does the quality of a resulting image suffer significantly when using a converter? Thank you in advance for your answers!
