    Surprising ResultsComparable to the Canon lens, and a less expensive option. Provides great images at a low budget price.

    A Decent Alternative… Though might as well get the CanonBefore buying the Yongnuo lens I would heavily consider what you may be using this lens for. In general, for portraits, the image quality is pretty great. I am of course always comparing this knockoff lens to the original Canon 50mm. So for purely taking photos, this lens might not be a bad idea although the autofocus doesn’t get quite as sharp as the original Canon nifty fifty. One of the main differences which I just mentioned is, of course, the lens’s ability to autofocus. It can be a little slower than the Canon and a little bit softer in some places. The other distinction which can be quite significant is the autofocus motor is very loud. The canon, on the other hand, is nearly silent. It’s also an STM lens which means the autofocus is quick and quiet. So if you are considering using this lens at all for video, I would highly recommend against it as you will likely hear it in your footage (even using an external mic I was able to catch glimpses of the motor). So buy with caution! The lens does work just fine and it’s a good lens that bears heavy similarities with the original Canon. Of course, what makes the Yongnuo enticing is the pricepoint! It’s about half the price of the original Canon lens. My response to this is that you will likely own any lens you purchase FOR LIFE. It will last you years and years and years. And in the grand scheme of time wouldn’t you rather spend the extra 50 bucks for something that is of higher quality? I know I certainly would. We’re not talking about hundreds of dollars more we’re talking fifty dollars or so more. I’m sure you can buy it used on ebay for even less. With that said, the Yongnuo is a decent comparison for PORTRAITS. For video, just beware that the motor is considerably quite loud. So the lens certainly works as prescribed and the image quality is quite comparable to the Canon however there are a few stark differences that set it apart from the original. Food for thought!


    Stop Agonizing and BUY THIS LENS!This lens is my favorite in my collection and works amazingly well on my Rebel XT. I thank myself repeatedly for purchasing this when I get a shot that just blows my little mind. If you are really agonizing over purchasing this or the real Canon 50mm equivalent lens like I did for months, stop mistreating yourself now. Order this lens ASAP and stop punishing yourself for NOT buying a Canon lens. You’re worthy and the first time you see what you captured, in all its detail, your smile will remind you that you did a great job.The quality of photos you will get for a mid-$50 lens will quickly put your mind to rest. Seriously. I could really care less that the lens is “lesser quailty built” than the Canon version. I do not purposely endanger my equipment because I need it and I do not have a backup. This is not a pro lens and I would expect that for $50 there has to be more plastic than metal. If anything, to me, this is a starter lens to evaluate what one can produce with this focal length and evaluate if you want to get the better built one from Canon. When you put this lens on, you probably will be like me and leave it on a majority of the time because it is a great walk-around lens and also delivers awesome portrait shots.The only problem I ever had was one time it would not auto-focus shortly after my purchase. Not sure what happened, but I removed it carefully, slid the switch for manual/auto a few times, re-mounted it and it was fine. It hasn’t happened since.Also, it’s a prime lens so you will have to make the mental change that there is not a zoom capability in the lens and you must physically get closer to subjects, or move further away. Some people may not understand this at first, or may not be able to physically move. So if you are looking for a zoom built-in, this lens does not offer that capability.Finally, make sure you remove all clear plastic lens covers before you begin to use the lens! The plastic on the internal side was a bit of a hassle to remove with larger fingers in action and I almost did not see it on the glass at first.Hope my words helped you and maybe even persuaded you to get off the fence and just buy it. I am very happy with mine and it’s been on my camera almost exclusively for 5 months now.

    Decent Lens for the Price…….I am a professional photographer and had a failure in one of my high end lenses at the most inopportune time. I sent my “L” lens off to be repaired and needed something to replace it until I could get it back. After a lot of research I just couldn’t find anything better for the limited amount of money I could spend. The ratings were good but I just couldn’t believe that this would give me the quality I needed. Having no other options I ordered it anyway to fill the need.What a pleasant surprise. After a minor glitch (my fault, explained below) I found this lens will give me crisp clear focus and colors. It is an excellent lens for those who cannot afford the top of the line lenses that will last forever but take forever to pay for.This lens is good for probably a year of continual medium to heavy use and then just throw it away and buy another. It is made of plastic and needs tender loving care to hold up for any amount of time but I think you will be pleasantly surprised at the quality of photos you can get from this. If you have a limited budget and need a lens that will get you those low light photos then buy this. Yopu won’t be disappointed. Just be careful on banging it around.Now a little help and the “glitch” I mentioned. When this was delivered I handed the box to an associate and went to a meeting. I got a call that the lens was horrible and the best focus was slightly blurry with a halo around everything. My initial reaction was that “You get what you pay for”. Upon my return to the studio I grabbed the lens and put it on a different body and got the same result. It looked like I was shooting through a thin film of Vaseline. Upon closer inspection I found that my associate had removed the protective plastic sheet from the front glass of the lens but not the small one on the back glass. (think of the plastic on the front of a new phone) If you remove both piece of plastic you should get some pretty good photos.

    CannonSon used for his camera.He loves photography.This allowed professional pictures where the background is blurred out and the subject being photographed to show up crystal clear. Providing and image that people love.Worked well. Compact. Nice

    Cheap rival to the Canon 50mm 1.8 iiThis lens is a great choice for a beginner photographer who wants to try out a 50mm lens but doesn’t want to pay $100This lens cannot compete with the new Canon 50mm STM lens, but when compared to the STM version’s predecessor (the Canon 50mm 1.8 mark ii), this lens stacks up very nicely. I would say that it does 95-98% as good as that lens and at a cheaper price point.I got to shoot some maternity photos for a couple and the lens performed relatively well, although about 50% of the photos did end up being out of focus and unusable and although some of this came from the candid nature of the shots, this lens spits out more of those out-of-focus shots than my other lenses do.Focus – 8/10it mostly does all right, but sometimes it will take 2 or 3x as long to focus compared to my other lenses.Bokeh – 9/10the bokeh in this lens might actually be better than the Canon mark ii’s because this lens has 7 aperture blades while the mark ii only has 5, making these bokeh balls much rounder and softer compared to the mark ii’s geometric design.Chromatic Aberrations: 6.5/10.When shooting into the light, you start to see a lot of discoloration around the shadowed subject, so for sunset portraits, that could be a problem, especially when you begin to edit the image (which you can definitely see in the 4th picture)Value – 10/10For the money, it’s hard to beat and for a beginner photographer, I would highly recommend it.

    It’s FineThe price is good and it doesn’t take awful photos, but I have some fixed focal length retro lenses I got off eBay for cheaper and they look much better. If you REALLY need an autofocus on the cheap I suppose this is your best bet, but definitely not for anything professional or even professional adjacent.
