Abstract
The present invention discloses a wide angle lens. The wide angle lens comprises, from an object side in sequence: a first lens with a positive refractive power, a second lens with a negative refractive power, a third lens with a positive refractive power, a fourth lens with a negative refractive power, a fifth lens with a positive refractive power, and a sixth lens with a negative refractive power. The wide angel lens further satisfies specific conditions: 0.80f1/f1.50, −0.50f2/f3−0.05, 1.15d1/d91.40 and T56min/d110.50. The wide angle lens can achieve a high performance while obtaining a low TTL.
