Qylur Qylatron Baggage-Screening Locker.Going through airport security never Favorite job everyone, but the locker system could change the process considerably. Canon's EF-S 18-55mm kit lenses have always been small, light and cheap and the latest versions have the very useful image stabilization feature.
These lenses have been and continue to be a good value when purchased as a starter lens in a DSLR kit, but they have never been a strongly desired lens otherwise. As one would expect from a kit lens, this lens is designed for everyone's most-common focal length needs. This is a moderately wide angle of view that is common with EF-S zoom lenses, but you will likely wish for wider on occasion. This is a nice angle of view that encompasses portraiture – but save the headshots for a telephoto lens. Portraits taken from a close distance will start showing perspective distortion - including big noses - and are best avoided. Though this lens is not far from the normal variable aperture crowd, few lenses have narrower max apertures than this one at comparable focal lengths. Being a variable aperture lens means that wide open exposure settings are going to change as the lens is zoomed to the longer focal lengths. Here is a table comparing the aperture step down focal lengths of some other Canon alternative lenses. Image stabilization has (practically) become a standard zoom lens feature these days and it is extremely valuable to me. In-lens IS will allow a camera to be handheld at very long exposure settings and provides a stabilized viewfinder image that aids in subject framing. Image stabilization does not stop subject motion, but it makes a remarkable difference in still subject photography.
This IS implementation is virtually silent (will not be heard in sound recorded in-camera during video capture) and does not causing image framing to jump around.
The rate of sharp images slowly drops until about 1 second where my sharpness rate reached 0%. Don't expect sharp images at these long exposure times under less-than-ideal conditions, but expect the amount of assistance to be similar. Here is a with and without image stabilization example captured at .8 seconds (handheld of course). You will get less vignetting from full-frame-compatible EF lenses on an APS-C format camera, but these results are not bad. The 18-55 STM shows a considerable amount of CA (Chromatic Aberration) until the long end of the focal length range. The colors you see are the different wavelengths of light being refracted by different amounts. Because software can (often) nicely clear up CA, it is my favorite lens defect (if I have to pick one). Stopping down (narrower aperture) a stop or two makes little difference in image sharpness in this range. The IS II lens is slightly sharper at 55mm, but the IS STM has some minor advantages in wider focal length comparisons. While the flare pattern is different from the IS II, which lens is better in this regard is mostly a matter of opinion.
This distortion is going to be noticeable in images with straight lines near the borders – such as in the photo shown below. The big issue with barrel distortion (or pincushion distortion) is that straight lines are rendered as curves. Relative subject sizes are also distorted with center-of-the-frame subjects becoming larger. Distortion also makes the original capture more difficult as it is hard to level a curved subject in the frame. The results of distortion are usually correctable with software, but this is a destructive process to pixel-level details. The 18-55mm IS STM lens gets a nice upgrade in the bokeh (background blur quality) department. The 18-55mm IS II's aperture blades are curved, but I could clearly see 6 blade edges in OOF highlights in some stopped-down-aperture images. Because this lens does not create a strongly blurred background unless shooting at minimum focus distance at 55mm, few will significantly care about this improvement. So quietly that you will need to put your ear next to the lens in a quiet room to hear the click sounds autofocusing makes. No longer does this kit lens model extend and rotate the front element during focusing as all of the previous EF-S 18-55mm lenses have done.


These filters are rotated to dial in just the right amount of effect – an effect that can greatly enhance some photos. When focusing turns the front filter threads, that effect is adjusted to something less than optimal. The lens hood can now be installed without the lens barrel extension turning the focus motor gears to one extent or the other – to gain enough resistance for the hood to turn into (or out of) place.
With a generally deep DOF (Depth of Field), this lens' AF system is not overly challenged to focus accurately enough.
The STM AF system is designed to allow continuous autofocusing during video recording when mounted to certain compatible DSLRs (Rebel T4i, Rebel T5i, Rebel SL1 and EOS M at review time). This feature works, but don't expect to track your kid running the bases at a close distance and don't expect production grade focus pulls. Slow subject motion is indeed tracked with reasonable performance – and the autofocusing prior to video recording is helpful. The 18-55 STM has FTM (Full Time Manual) focusing, but it took me some time to figure out this feature as it is not the same as with many of Canon's other FTM focus-supporting lenses. The key is that the shutter release must be pressed half way to enable manual focusing after autofocus lock. You can't just pick up the camera and manually focus this lens unless the lens is set to manual focus-only mode (a switch). This lens is far from being parfocal – the subject does not remain in focus as the focal length is changed. And, if camera is powered off or in sleep mode, adjusting focal length typically results in a very out of focus subject. But, if the camera is powered on and awake, the lens automatically adjusts the focus to remain on the subject.
Instead of a slim, raised, knurled area molded onto the end of the wobbly extending lens barrel as found on the IS II, the 18-55 STM gets a real manual focus ring. No longer does the image framing change greatly while manually focusing the lens and focus adjustments can now be very precisely made. Manual focusing is only available when the lens is mounted and the camera is powered on (and awake).
While this lens is built modestly better than the IS II (the extending barrel has less wobble), it is not much different in this regard.
Upon installing the IS II, the camera could no longer set the aperture and then gave an 01 communications error. If I was photographing something important, this may be the last lens I would choose for doing so.
This lens is most compact around 30mm and increases in size modestly at both focal length extremes. In the first 18-55mm group picture, the STM lens shows that it is modestly longer with a trimmer waist line. In the second image with each lens fully extended for both focal length and focus distance, the lenses appear to be equal without taking their hoods into account. But, this is a positive change because the new hood provides better protection from bright lights and from impact. Of course, there are probably not too many 18-55mm STM lens owners who will pay the relatively heavy price for the hood. Note that the hood will sometimes create a shadow in some images taken using a camera's built-in flash.
There are not many situations where I would recommend a quality UV protection filter for such a lens (I rarely recommend low quality filters) because these filter cost too much relative to the cost of this lens. Circular polarizer filters, however, are worth adding to any lens unless your photography never makes use of such. Put poor quality between your subject and a good camera and you typically get poor quality. The small size makes this lens ideal for kid-sized hands and the light weight keeps photography fun for kids - for long periods of time. If you only need the wider angles, this lens might be an OK choice (from an optical standpoint). If your wallet is light or you need to keep your DSLR light, this lens might be a good choice.

We asked on Twitter what our followers favorite digital slr camera was and nearly every answer was different, or was a wish for an upgrade to an existing model.
We can however show a list along with some explanations, that way you can make a more informed decision for buying the best dslr camera (and most affordable) that meets your needs.There are hundreds of dslr cameras on the market, some with very close matches of specification or price. The process we used to come up with this list of the best was based on the same process we used to buy our favorite dslr, the Canon 7D.
Our criteria for choosing the best dslr camera for your needs is based on price, resolution and speed. Tallying up the scores gave us our results, with the best overall camera listed last.What features were we interested in when considering various models of dslr cameras?
Our review of cameras was assuming that most people reading this article are not professionals but also I not absolute beginners either.
We assume that most people looking for a DSLR are likely to use at least some manual settings, but we also appreciate consumer type features such as a built-in flash. Of course, because we are not targeting high-end professionals with our list of the best dslr cameras, we appreciate lower prices versus high costs (the more affordable the camera the better)! For us, HD video in our DSLR camera was not a huge factor in our decisions though we are certainly happy when a camera has that feature.Why are speed and resolution major factors for our list of the top rated DSLR cameras? We know some people would argue that your lens and sensor have a bigger impact on the output quality, and the end result is the whole point, right? Well, sure, but I started out in DSLR photography with a Canon 350D and two areas where I felt really limited were the frame rate and the resolution. Canon EOS 1000DThis DSLR camera was launched in 2008 and is aimed squarely at the entry-level market but despite that positioning and age, still packs in some serious features. If price is your main factor then it is well worth looking at, as this is one of the best and affordable DSLR cameras on the market.Click here to buy the Canon EOS 1000D DSLR9. The specs won't set the world alight, especially the low frames per second, but the price is competitive and the resolution is decent at 14 mega pixels.
Many people tell me they prefer the ergonomics of this Nikon body, which is worth considering into the equation.Click here to buy the Nikon D3100 DSLR8. That said, even though the product was last refreshed in 2008, it is a fantastic performer. Full frame sensor is probably the headline feature, giving it extremely good quality in every environment you can throw at it. Resolution-wise you are looking at 21 mega pixels, which is good enough for some excellent prints at large sizes without much post processing. The full frame and the resolution mean many professional photographers use this as their go-to DSLR camera. As mentioned earlier, expect this to be rectified soon, in which case it will likely be a dominant player once again.Click here to buy the Canon 5D MkII DSLR7.
Unfortunately, while an excellent and popular camera, the newer Canon 60D beats it in all departments in terms of specs. Still, Nikon fans will tell you it works and feels better in actual use, and it is a good choice if you already have a Nikon lens collection.Click here to buy the Nikon D90 DSLR6. Nikon D3XIf you are looking for a pro level DSLR camera then you are going to be heading up the price scale but also getting better performance for your money (and usually build quality). Obviously it will price out all but a minority of camera buyers but the image quality served up by its superior innards and 24 mega pixel sensor are very impressive.
Canon Rebel T3i Another entry-level DSLR camera, the Canon Rebel series has historically been the sweet spot between amateur price but respectable specs.
This brand new refresh is the only 2011 camera on the list and packs 18 mega pixel resolution for a low price, potentially below $800 if you spot a deal!
Canon 7DIt has to be said, the Canon 7D won out among our top ranked DSLR cameras but not by a huge margin.
The faster frames per second helped, plus the build quality and hand feel (many Nikon owners would disagree there).
Yes, you might be able to get a good deal, seeing as it is already being seen as an older model. If you are anything like me though you will love the results.Click here to buy the Canon 7D DSLRSummaryThe best DSLR cameras is the kind of subject that naturally leads to discussion, arguments, and a lot of subjective personal taste, so let me pre-empt the flames by saying this is MY list of the best DSLRs.
