Definition: In this task, you're given a review from Amazon. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral, 4: good, 5: extremely good.
Input: The lens produces incredibly sharp images with very low distortion as advertised. My main complaint is the amount of flare produced when this lens is used in bright sunlight. I purchased this primarily to use as a landscape lens and had to throw away more than 2/3 of the images i captured with it due to flare and chromatic aberration. If you plan to use this indoors or for astrophotography, you will likely be very pleased. If you intend to use it in bright sunlight, you will likely be very disappointed. For me, it was not a keeper so I returned it.
