      This is a no brainer. BUY THIS LENS!

      • My Best Buy® MemberMember

      I just recently bought my T4i/18-135mm kit. I wanted a prime lens to compliment the zoom. I've already owned the "Nifty Fifty", and 'was' just going to repurchase that one, because of it's decent image quality and it's price. However, after reading just about every review out there, and viewing countless photos out there about the 40mm pancake, I decided to try it instead. I'm glad I did. The image quality completely destroys the 50mm f/1.8. Granted, the Shorty Forty is only an f/2.8, so it isn't going to give you quite as awesome background blur as a wider aperture like the Nifty Fifty....but the image quality, in my opinion, more than makes up for it. Sharp, nice contrast, nice colors, and a nice focal length to work with. I LOVE THIS LENS! I have guys that own L-lenses complimenting the photo quality of this lens. Seriously - for $200 or there really anything to think about? Not in my opinion. I didn't buy this lens for the size, because, if Canon made a cute little diminutive lens that sucked at taking pictures....big deal if it's small and compact, right? But, this lens does NOT suck at taking pictures, AND it happens to be small and compact, which to me is an added bonus. Bottom line: Unless you already have this focal length covered with another GOOD lens that takes GREAT pictures, you should buy this lens. If you're looking for your first prime, you should buy this lens. Nifty Fifty's are cool, they have their place...but the image quality of the Shorty Forty completely blows it away. Like I brainer here. The two attached photos were both at f/2.8, ISO 100, 1/160s. **Side note: For video, it's true what you've heard elsewhere: It's NOT "silent" by any means. However, if you're doing anything serious with video, you're not going to be using the cameras onboard mic anyway. I personally use a Zoom H4N recorder with a hot-shoe mount for my audio, and it works great (and doesn't pick up the focusing noise from the lens).

      Pretty Awesome But Falls Short of Perfect

      • Verified PurchaserVerified Purchase
      • My Best Buy Premier Silver MemberElite Plus Member

      This lens has the amazing new "STM" designation. STM lenses are supposedly made for videographers. I also own the 18-135 STM lens. That lens is good for video; the 40mm not so much. First, the good stuff. The lens is tiny and also fast. Not 1.8 fast, but for its size it's pretty impressive. The overall image quality is pretty phenomenal . . . here are photos for you to check out. Now for the bad: 2.8 is pretty fast, but just not fast enough. And the STM (stepper motor) focusing system is ridiculously loud to be useful at all for video. They say it's silent, fast and accurate. Well, it's accurate, but it's not fast and it's not silent. It's probably about (based on feel alone; not real data) as fast (focusing speed) as my 50mm 1.8. It's definitely not USM. And the focusing noise is stupidly loud in video. It's not all that loud when you're just listening; in fact, you might even miss it. But when you play back the video, it's loud. And the noise is just as apparent whether auto-focusing or manually focusing. Picture quality? Awesome. Size? Awesome. Price? Awesome. Focusing mechanism? Not so awesome.

      Small & Sharp


      This prime lens has it all, it's image quality is excellent, it's well constructed, and it's affordable. Image quality on my 60D is great. At 2.8 it is sharp, and provides awesome bokeh. It is very similar to the 50mm 1.8II, but is a bit more user friendly for those of us with APS-C sensors. I can shoot indoors easier due to its focal equivalent of 64mm compared to the 50mm being more like a 85mm when used on an APS-C camera. No vignetting in the corners either. Build quality is excellent, the metal mount and mechanicals give the feeling of quality beyond its price. The lens is really small, it will probably become a lot of people's body cap when traveling. It's size makes it perfect for candid photography, it's not imposing or distracting to the subject. Finally affordability, at 200 dollars, I would recommend it to anyone with a camera. It's extremely versatile and does not require a large investment, I would say Canon should have a camera kit with this lens, much better than what the kit 18-55 offers.

      Perhaps the best bang for buck all around lens

      • My Best Buy® Elite Plus MemberElite Plus Member

      First off, I am somewhat of a DS:R beginner, and this lens is pretty simple. Bought this just to pair with my already small Rebel SL1 crop body, and I love the portability. Even with a protruding filter on it, the lens is still low profile. Build seems solid despite it being plastic. Mount is metal, and goes on body with a tight but snug fit. Thin focus ring is made of textured rubber, and feels smooth but not loose. Image quality is pretty impressive. GREAT bokeh can be achieved. This is not a macro lens, but I am able to take beautiful shots from about 8 inches away from subject. However at this close range, I have to use manual focus, as auto will not pick it up. Speaking of which, auto focus is rather slow, so not really a good lens for action shots. Because of size and portability, this lens is great for a "walkaround" lens. I bring this lens mounted on my SL1 almost everywhere I go, and snap away using only one hand like its a point and shoot!

      A Little Gem

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I already own 7 or 8 Canon lenses and this was largly an impulse purchase (at under $200.00 it's well within the reach of almost all photographers). After reading many positive reviews online I was curious as to its' image quality. The quality of the images this lens produces is excellent, very sharp, very clear with an excellent depth of field. The focus hunts a little but locks on fairly quickly, the 2.8 max aperture makes this a good choice for low light. The Canon 50mm f1.8 is a few dollars less and offers one stop more light collection but doesn't seem as well made as this lens. The 40mm field of view is close to what the human eye sees so the framing is very natural. For me this lens is useful for candid and street photography, it makes a camera like the 5D very un-obtrusive and non threatening, my professional cameras look like slightly oversized consumer superzooms with this lens on them and people go back to acting naturally much more quickly than when a giant white lens is pointed at them. If you are curious or just getting into photography I can highly recommend this little gem of a lens.

      Excellent optics, weird manual focusing

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I'll keep this brief... This lens has excellent optics. It easily bests my Canon 24-105mm f/4.0 L lens at 40mm, hands down. This lens is much sharper across the entire image. The only down side to this lens is the STM system it uses for focusing. While STM is faster than the conventional motor used in the 50mm f/1.8 lens, it is still noisy enough to be heard on video. In addition, manual focusing only works when the camera supplies power to the lens, so when your camera goes to sleep between shooting images the focus ring doesn't do anything at all. It's easy enough to wake it back up -- just a half-press of the shutter button -- but something to be aware of. At f/2.8 maximum aperture, you won't get as shallow a depth of field on this lens as you will on the 50mm f/1.8 (which is considerably cheaper) but the image quality overall on this lens is significantly better. So if you're most concerned about sharpness, get this lens. If you're after a shallow depth of field and maximum bokeh, the nifty fifty is the better choice.

      Great addition to every lens collection

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      This is a very light weight fixed focal length lens. Image quality is very good as sharpness is concerned, not that great as vignetting is concerned, though adobe Lightroom can fix that in a second. I'm using it on a EOS 7D, which makes it a 64 mm equivalent and as such a bit too long for outdoors/landscape but good for portrait and mixed use. I use it outdoors where my primary focus is on longer range pics (ef 70-200 or 100-400 mm) and I want a wider lens available without having to carry the additional weight. Turns out the very low weight allows me to shoot at longer exposure time without blurring the images. wish it would be a f1/1.4 but f1/2.8 is what can be expected for that price. This lens now is part of my standard selection. The lens is good enough to deserve a well coated UV filter such at the B+W MRC 52mm to avoid glare; the bestbuy cheap UV filters protect the lens but add noticeable glare when shooting toward the sun.

      Really nice Len

      • My Best Buy® Elite Plus MemberElite Plus Member

      Bought this before black friday of 2013. Great Len, shoots really fast just like any other prime lens. I do like the 50mm more but love the pancake look. it drawns people attention when i put this super small lens on my T4i and 5DM2. The bad... if you get one, Please update the firmware to the most current. there is a problem on the lens when using filter or putting pressure on the tip. it gets stuck and does not focus no more until remove the lens and reattach, that resets the Len to go back to normal. If you are shooting with no filter, chances are you won't notice it. I believe it's pressure on the lens and makes the motor stuck. Was going to return it but decide to update the firmware to see if it fixes it. after update, it's been working fine for me. I stop using the filter recently as it's so cheap that if gets damage i can just get a new one. Have fun
