The Yongnuo YN EF 50mm F / 1.8 lens is one of those secrets that China has well-kept. It is an investment with nice dividends. I invite you to lose the love of a couple of dollars and give this accessory a chance. Buy it here on eBay.
The Yongnuo brand is a perfect alternative to Canon. Its versatility, its price, and its definition are an indisputable couple for those who wish to master the art of photographic portraiture. Although, be aware: the lens is ideal for photography but not for video; it defocuses the background very well to give you that impressive bokeh effect that you see in many professional photos but it is slow in motion scenes. This is a good option if your budget is not enough to buy a Canon 50mm f1.8. But, compared to it, the Yongnuo lens autofocus is extremely high and much slower than the canon lens. The autofocus seems surprisingly accurate but you don´t have to take anything for granted. It also has manual focus, but is not full-time like in some Canon models. As if that were not enough, it is a relatively fast lens (f1.8) and adapts quite well in twilight situations, and works well enough for portrait photographs.
The truth, when I bought it, I expected a lens less defined or worked, but to my surprise, the images are clear and the bokeh is good. Again, I would not recommend this lens for those who seek to photograph their children or pets in movement or use it on events where fast movement prevails: like a wedding or a Quinceañera, for example. Bad idea. The autofocus is slow and, sometimes, imprecise, and makes a lot of noise. If you are a manual focus person, this lens is perfect for you, the image quality and the bokeh effect are very good, especially for portraits. I do not regret buying it and it is THE lens for most occasions: perfect for the price and ideal for beginners. In sum: this is a very light lens and a little noisy, but for the price on eBay, it’s worth it. Fantastic for manual focus portraits, not so good for autofocus subjects in fast motion.
