If you need a cheap WR lens for occasional usage in rainy conditions or if you want a cheap wide angle lens this, or the DA counterpart, is a reasonable choice, but if you can spare the money you will probably be more happy with a DA 20-40mm or a DA 16-85mm lens in the long run.

especially the periphery of the image circle showing color fringing along lines of strong contrast running tangential (meridional, right angles to radii) as this is where the greatest difference in the magnification of wavelengths exists. But, an inconsistent focus ring rotation rate change can prove somewhat maddening when trying to quickly rock the focusing ring back and forth to fine tune focusing. Ok being picky it has a bit of barrel distortion at 18mm, and it has a teensy bit reduced contrast compared to some other lenses in it's focal length range, but hey it's just a hundred quid! Since CP filters are orientation-specific for their effect, keeping the filter properly rotated requires plenty of patience. The USM, I, II USM and II are similar, differing in the focus motor type (the I and II appearing only as kit option lenses, i.These filters are rotated to dial in just the right amount of effect and when focusing turns the front filter threads, that effect can be adjusted to something less than optimal. The lens if very light partially due to its plastic mounting ring, which really doesn't bother me on a lens this size and it makes it a more carry-able. I wasn't able to do a direct comparison but I feel that the Sigma outperforms the canon in most areas, except CA and color balance. Few lenses are smaller or lighter, and as mentioned, smaller is one of the benefits this lens brings over the previous EF-S 18-55 STM. is a Canon-produced wide-angle to mid telephoto zoom lens for digital single-lens reflex cameras with an EF-S lens mount.

The light weight and compact dimensions of the lens make this an ideal companion for compact entry-level SLRs. From easy craft ideas to origami-style 3D models – bring the paper fun into your daily life and add a personal touch to your creations with the editing function.

There are a lot of people going to bed hungry tonight if the money is just burning a hole in your pocket! I now use a 24/105 L series lens and the image quality is far superior, but the cost was 7 times as much. At 18mm focal length, the lens has a fairly wide angle, which will help you nail some very beautiful landscape shots. This system is virtually silent (inaudible in sound recorded in-camera during video capture) and the image framing does not jump around at startup or shutdown.

As everyone would expect from a kit lens, this lens is designed for everyone's most-common focal length needs. Image sharpness is essentially even across the frame, and doesn't exceed 2 units on our scale of 1-12. Utilisation en paysage principalement pour ma part au grand angle, je n'ai rien à redire des photos réalisées avec un 7D très bon piqué. Not only does rotating the focus ring change focus, but even slight side-to-side pressure changes both the focus and the subject framing.That was the case with the 18-135 IS USM and I am not surprised to see the same again in the 18-55mm f/4-5. It doesn't cost you anything extra when you use these links, but it does support the site, helping keep ePHOTOzine free to use, thank you. Even if you're not interested in the image stabilization that's been added, the addition of the aspherical lens element (and whatever other fine-tuning the lens wizards have been up to in the lab) shows off improved sharpness and resistance to chromatic aberration.

Since this lens is weather resistant it makes a perfect inexpensive companion to my K-50 (also weather sealed). The lens is not of particularly high image quality, which is much more obvious on modern higher resolution cameras. The IS version beats the non-IS version handily, especially in sharpness, but noteably in distortion and resistance to chromatic aberration. This allows photographers to use shutter speeds up to four times slower than normal with no perceptible increase in image blur - ideal for shooting in low light.

The front filter thread rotates during both AF and MF, complicating the use of polarizers, gradient filters, and rectangular systems. IS STM lets you take your EOS to more places, delivering sharp punchy images even in low light thanks to a 4-stop Image Stabilizer.
