Amazing lens. Well worth the price. I primarily use this lens for weddings. Weddings tend to have dim lighting so I love primes. This was a great prime to add to my collection. The 1.4 F Stop makes everything look great.

I have had this lens for one and a half years. It takes great images, and seems to have good quality materials. I like having the aperture control right at my fingertips. However be warned: the shims that hold the rear element in came un-threaded on my model, and although it seems like a fairly...

One of my favorite lenses on the planet and I couldn't be happier with my purchase!!!
