Sigma 18-50mm f/3.5-5.6 DC

see the whole gallery in large	APS-C sized image Lenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. No Ultrasonic AF Lenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. No Low Dispersion lens element is used Low Dispersion lens elements help to reduce chromatic aberration. Not stabilized Image stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Metal mount Cheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important. No Internal Focusing Internally focusing lenses don't change their size while setting focus. The front lens is rotating The fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. No drop-in filter support Drop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type.
Compact-Lightweight zoom lens has a maximum diameter of 62mm, overall length of 67.5mm and weight of only 250gr and filter size of 58mm. Compact dimensions offers superb handling and mobility. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance. We took digital characteristics into consideration when designing the lens power layout and created the most suitable lens that makes high quality images a reality throughout the entire zoom range. We used the most appropriate coating for digital products to cut down flare and ghost caused by digital SLR cameras and to produce the best color balance. It can be used with the supplied lens hood to block out extraneous light. 18-50mm F3.5-5.6 DC zoom lens has a minimum focusing distance of 25cm at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5. The focus ring provides easy operation in manual mode. A distance scale on the focus ring is an easy to use and convenient addition.

Basic zoom lens, for cheap

Nov 29, 2009

What can you say? I bought this as a cheap back up lens. This is a basic, no-frills, inexpensive lens. It is well-made, but picture sharpness is hit or miss, it seems. I am an amateur, so I can't tell if there is any distortion at either end of the zoom range, or in the middle. I haven't seen any significant chromatic aberration yet, but I expect there to be some considering how cheap this is. The auto-focus has difficulty in dim light and bright (sun) light. I wouldn't say it is better or worse than the kit lens that came with my XSi (450D)...but, that lens has the benefit of IS (image stabilization), which the Sigma 18-50 mm f/3.5-5.6 DC does not. If you are on a tight budget, this may be for you, otherwise, steer clear. There are other, better lenses out there (but they will cost you more). By the way, it does come with a small lens hood.

Inexpensive Sigma Lens

Jun 11, 2010

I purchased this lens because of is low price. I recently purchased a Canon 7D and wanted a wide angle lens but really couldnt afford good glass. This lens gets the wide shots but it's not the sharpest.(nor is it close.) I am happy witht he lens based on my current need for a wide angle and it's super low price.
As soon as I get the funds I will be upgrading. Good for now.

Better than Zuiko 14-42mm

Mar 29, 2008

I've been using the Zuiko 14-42mm for over 3 years now on my Olympus evolt e-300 , and the Sigma 18-50mm lens is far better. I have just recently got it and have used it many times. It's now become my favorite lens.

The Auto Focus is far faster, the Manual Focus is very smooth. It's easy to switch from one another with a click of the button. The images are clearer and the focusing is amazing on it for selective focusing. Fits good in the hand and everything turns and moves smooth.

The price is amazing.

Only problem I see, is it feels delicate compared to the Zuiko and the shipping was not 2-3 days like I order, more like 8 but it's all good.

Excellent lens

Dec 8, 2005

I purchased this lens to use with my Olympus E-500 body. I was skeptical as to the image quality because of the low price. I'm glad I decided to give it a try. It takes excellent sharp pictures. I would highly recommend it!

Awesome Macro and Aspherical Lens from Sigma

Oct 29, 2007

I give this Sigma lens a five star.

This Sigma lens is a improvement than the Olympus E300 Packaged lens I got from: Zuiko 14-45mm f/3.5-5.6 Digital SLR Lens.

I get sharper and clearer pictures then the Zuiko lens I got with my Camera.

Thank You and Merry Christmas

I saw the price of this lens and I was alittle skeptical. I read the the person's review of this lens, so I decided what do I got to lose and bought it. This is an amzing lens for the price I paid for. I'm really pleased with the results of the photos. I recommend this lens to anyone who is on a budget. You will be suprised when you see your photos.

Excellent Lens

Mar 25, 2009

This is a very good Lens, I'm using it on my Olympus E-300 and it is better than the original lens the camera came with. Gives you a good sharp picture and it operates very well in the zoom mode. Also adds a classy look to your camera.
