At under $500 each, these fast Sony E mount primes should not be ignored.
Something extraordinary is happening in the world of Sony E mount lenses. We went through a period of massive prime lenses that required a gym membership to use. Now, we’re being graced with super small, fast primes. Not only are these prime lenses outstanding when it comes to image and build qualities, but they’re also priced right too. After the break, we’re going to look at nine Sony E mount primes that cost less than $400 each. You simply can’t ignore lenses this good that are also wallet-friendly.
One of the biggest lies is that you have to spend large amounts of money to get great lenses. This simply isn’t true. You can get lenses that are more than good enough for the vast majority of photographers that cost under $400. These fast Sony E mount primes prove this. All of the Sony E mount primes we feature here scored well in our reviews, and we highly recommend them. If you have a budget of $400 or less, and want a new lens, take a look at these Sony E mount primes.
