This zoom lens was exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of digital SLR cameras, and this produced a compact lens with a maximum diameter of 60mm (2.3 inches), overall length of 67.5 mm (2.6 inches), and weight of only 245 grams (8.6 ounces). It has a variable angle of view of 69.3 degrees to 27.9 degrees. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produces a high level of optical performance. The 18-50mm f3.5-5.6 DC lens has a minimum focusing distance of 25 centimeters (9.8 inches) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5.

Nice wide angel lens giving out details in footage

I've used this lens for family portraits and weddings. It fits the bill for large group shots, and when I need to get wide. It is reasonably sharp for an inexpensive lens. Not as sharp as Canon's 17-40L but it's not priced to be either. My only issue is the red CA that is in nearly every image. I know when I process my pics from this lens the first thing I do in Lightroom is fix the CA.

Love to play with this lens. I bought it used from Adorama, but it has been fun. Sometimes, in auto mode the exposure is too dark, but it easy to work around.
This simple and inexpensive lens has for the price pretty good performance, better than the Canon kit lens. For general use I would recommend stepping up to the 17-70mm or 18-50mm 2.8ex dc that have much better performance.There is one alternative use for this lens: Infrared and Ultraviolet Photography. For IR (using a Hoya R72 filter) you will not get hotspots and most Canon SLRs are sensitive enough to IR. This lens only has 8 elements and simple lens coating, so it actually can be used for near UV photography as well (with a B+W 403 filter). I must warn that Canon SLRs are very insensitive to UV and records on the blue channel only, so expect 30-45 second exposures on sunny days and you'll get significant IR contamination through the red and green channels. ... MoreThis simple and inexpensive lens has for the price pretty good performance, better than the Canon kit lens.

Nikon and Pentax SLRs are much more suitable for UV photography though with exposure times around 5 seconds on sunny days.
For the price, it would be a great lens, if it wasn't for the front focusing issues. In fact, this was my first introduction to front focusing - and this lens had it in spades.Construction seemed fair - but I'm no expert on that, yet. And for the price...
I bought this lens as a back up wide angle and with the good reviews I was reading for such a "cheap" lens I didn't think I could go wrong. So far I must agree with all the others it has proven to be a sharp lens. Most of my pics have been taken outdoors so the f/stop doesn't bother me but I think for indoors shooting it could be an issue...but easily dealt with. The lens feels very light on my camera and does not interfere with handling while not in use. My only complaint thus far with this lens is the manual focus ring feels very loose...I don't feel it is a fault with the construction of this particular lens, just an overall design "flaw".
Great lens with tack sharp focusing capabilities, works extremely well in low light and great construction.
Construction seems good. I droped my original Zuiko lens from a few feet and it broke. This one has'nt been subject to any stress Yet. The price difference made it worth a try.
