And the answer is, “no.” You should not own a lens like that, not if you’re an amateur photographer anyway. No great amateur photos have ever been taken with a telephoto zoom lens. (OK, I am sure that of the billions of photos posted on the web, you can find at least one great amateur photo taken with a telephoto zoom lens, but the point is that it’s a rarity.)
If you’re a wedding photographer and need a telephoto zoom to take pictures of the wedding ceremony, then sure, go for it. But if you’re a “professional” photographer, then you probably aren’t reading my website for equipment advice, and honestly I don’t have any good advice for you anyway. The only thing I know about wedding photography is that my sister overpaid for mediocre photos (but she doesn’t realize the photos are mediocre).
Somewhere out there, someone may ask, “but maybe I ‘need’ this lens to photograph my kid playing sports or something like that.” No, you’re kid doesn’t want the embarrassment of their parent carrying around a massively huge lens while every other parent is just snapping pictures with their iPhone.
Still don’t agree with me? That’s why at the top of the blog it says “For entertainment purposes only. Don’t take anything in here too seriously.”
