## Questions & Answers

**Q: How wells dose the Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens perform in low light situations?**
A: This is a bit vague, so I am going to shotgun you some responses here.

1.  Depends on camera - If you have a full frame camera like a 6D or 5D, you can use higher ISO without gaining too much noise.  So this lens can be decent, though I would think the lack of a wider aperture or IS will still hurt you.  IF you have a crop frame camera like a Rebel, mid range (80D, 77D), or 7D, then it is not the lens for you.  On those camera the EF-S 17-55mm F2.8 IS USM is a much better choice for 50 dollars more.  It has several advantages over 17-40mm; just as wide with a longer reach, a full stop more light, image stabilization, and significantly less distortion (the 17-40mm is worse at all levels of the zoom, even 40mm is worse that the 17mm of the 17-55mm).  The 17-40mm is designed for full frame cameras, and while it will fit, the 17-55mm is made for a crop sensor body, and thus is optimized for sharpness with that setup.
2.  Depends on the intended use - We talking indoor sports?  Then no, this will not be good for that on any camera.  Astrophotography?  Also no, you would want somethign that is at least F2.8 for that.  Taking shots of kids playing in the house?  Maybe, if you can live with having to bump your ISO up to higher levels to get exposure up.  Museum?  Again, higher ISO to get that better exposure, or a flash.  Can't be a built it flash either, has to be a speedlight, as a built in flash will cause a shadow in your photos from the lens Blocking part of the flash.  Landscape?  If you are using a tripod and can therefore shoot whatever shutter speed you need at whatever ISO you want, then it can work.  But if on a crop sensor, there are less expensive options for all that, so if you have one of those then look at the EF-S 10-18mm instead.

I just really don't suggest this lens to people most the time, as I feel that for the money there are better choices.  On a full frame, from Canon, this is the least expensive option, but if you can save up a little longer, then I would suggest the EF 16-35mm F4L IS USM instead.  Not only do you get 4 stop IS that will allow you to shoot at much slower speeds in low light, it is also the sharpest wide angle lens that Canon makes.  It's 1000 USD compared to 750 USD, and worth the investment if you can wait until you have the money.  If you have a crop sensor, then the other two lenses I suggested are a better bet.

**Q: Im replacing a 18-135 efs lens. its between this and 16-35mm. i will use it for street photos, landscape, and portraits. money is an issue. thoughts?**
A: That is a tough question.  While both lenses have similar focal ranges, the key difference is that the 17-40mm has a max aperture of f/4 and the 16-35mm has a max aperture of f/2.8.  That allows the 16-35mm to be more useful in low-light situations, as well as situations when a relatively shallow depth of field is desired.  I take mostly landscape shots, and the 17-40mm has served me well for that purpose.  I also imagine it would be good for street photos, assuming you wouldnât be needing a shallow depth of field.  Given I donât usually take portrait photos, I canât comment much on that, but if money is an issue, I feel you could get by with the 17-40mm.

**Q: Wondering how this lens will do with shooting sports?  thanks!**
A: It really depends on what your looking to achieve with your shots. If your looking to get the "Big" picture then this is a capable lense. If your looking to get the sweat flying off someone's eyebrow then this wouldn't be the lense to use. I shoot with a 300mm 2.8 for sports. Sports are extremely tough to shoot.

**Q: I'm looking for a lens for my RebelXSi to shoot interior shots of rooms, aka House Beautiful, Architectural Digest look. Yea, nay or what else?**
A: Remember you'll need to factor in  x 1.6 for the crop sensor... But it should work but expect to see 27.2-64mm not 17-40mm

### ⭐⭐⭐⭐⭐ Must-Have for APS-C Cameras
*by P***V on December 28, 2009*

If you're shooting an APS-C Canon and you've decided that you only want EF full-frame lenses for future use on a full frame camera, the 17-40 is a must-have. The focal range on the cropped sensor is 27 to 64mm which covers a large range for the majority of shots most people are likely to take. I've found this lens is perfect for social gatherings and essential for group shots. The size and weight is perfect on the 7D, making this my favorite lens for handling (compared to the 24-70 f2.8L and the 70-200 f4L). The build quality is superb. The focus and zoom rings couldn't be smoother and AF is fast. While this is a sealed lens, I hear that it's not fully sealed until a filter is fitted. With one in place, the zoom extension is completely internal, so there's no change in length when zooming from wide to the long end.This lens is a fixed f4. If you buy the lens with the understanding it is not an f2.8 and will not get you the lower ISO and/or faster shutter speed of an f2.8, the lens does very well in most shooting situations. On the 7D it's even better with the excellent high-ISO performance of that camera (I can shoot at ISO 3200 to 5000 without much concern). While it is reasonably sharp at f4 across the focal range, it is not as sharp as when stopped down to f5.6. Also, boarder sharpness falls-off a bit wide open and close to 40mm. However, these are not big issues. Contrast and color with this lens is excellent. My only caution from experience is to be careful when adjusting the point-of-focus to depth-of-field balance with the micro AF adjust on the camera (if you have that feature). What may appear to be a correct adjustment with a focus scale sheet that uses the center of the field, may end up causing excessive edge softness of your images due to the edge of the frame starting to fall out of the depth of field. I believe this may be due to the field curvature characteristic of a wide angle lens where the focal plane is not equidistant from the camera lens but slightly curved. I spent some time setting the correct AF micro adjustment by photographing a large bulletin board with very small lettering and symbols across both dimensions while making sure the camera was pointed square to the center so that all corners were equal distance from the camera. Once you have this dialed-in, you can test the center-to-corner sharpness of your lens at different focal lengths and apertures and determine whether you may have any sharpness issues with your copy. Initially I thought I had a bad lens copy that was soft and de-centered, but after getting this procedure right, the lens proved to be sharp.While there are other excellent options such as the Canon 17-55 EF-S f2.8 lens, this one is full-frame compatible, it's weather sealed, it has superior build quality, it's an L lens with that unmistakable red ring at the end, and it's the next greatest lens bargain second to the 70-200 f4L. While the hood may look odd, remember that it was intended for a full-frame camera where this lens would be a true 17-40mm - making a shallow hood necessary.

### ⭐⭐⭐⭐⭐ Wonderful step into the L world!
*by J***N on February 28, 2009*

I purchased this lens to accompany my new 50D. The first thing I will note is the amazing improvement upon image quality when moving from the 18-55mm IS kit lens to this one. As there is quite a bit of difference in build quality as well as price range, that should come as no surprise.If you are shooting with a crop body camera, Rebel/XXXD or xxD body. The extra range on the short end of this lens becomes really important when shooting group pictures, landscapes, or your shooting space is really tight. The difference seen between having 17mm at the short end and 24/28mm is really REALLY noticable and allows you to get some landscape and close quarter pictures, you might not have been able to take.As far as build quality goes, the lens is VERY solid. Metal construction with LD glass elements and very smooth focus USM motor and like butter zoom ring, it all just feels wonderful to use. You will definitely notice a difference if you try to use a lower quality lens.Optical quality is amazing. As the sensor on the 50D is very dense, it becomes easy to see the flaws in lower quality glass. This is not the case with the 17-40L. Though I would have like to be able to get the extra f stop that comes with the 16-35mm 2.8L , the decrease in weight and the HUGE decrease in price makes the 17-40L a better deal for me. After all, the bokeh becomes the only reason that the fstop is so important(i wouldn't discredit this because smooth bokeh makes portaits great) , as the difference between f4 and f2.8 is going from about ISO 200 to ISO 400, and with the dramatic increases in high ISO perfomance, it is likely you will not greatly notice the difference. If lighting is THAT bad, you should really be using a fast prime, such as the 50mm 1.4 or an external flash.The EF mount makes it easy for one to make a switch to full frame camera in the future and will leave you with a very useful ULTRA-WIDE lens on FF cameras.Overall, I am very pleased with my purchase, and if given the opportunity to purchase again, I would happily do so. In the future I plan on paring this lens with a 70-200 f4 L which I understand is one of the best priced and best value canon lenses made.
