無超聲波自動對焦一般來說,超聲波對焦鏡頭比傳統對焦鏡頭靜和快。 使用了一個或更多的低散光度鏡頭元素低散光度鏡頭元素能減低彩色的色差。 不穩定影像穩定器能減低手震時產生的模糊影像,特別在長焦距或陰暗情況下。根據倒數的定律,影像穩定化比無影像穩定鏡頭能有1到3個光圈優點。 塑膠接腳平價鏡頭通常會使用塑膠接腳,而較昂貴的專業的鏡頭會使用金屬接腳。一般來說,金屬接腳會比較耐用的及當鏡頭改變很多。當相機主要使用一個鏡頭,接腳物料並不是很重要。 內置對焦內置對焦鏡頭不會因設定焦點而改變其大小。 無內置變焦內置變焦鏡頭不會因改變焦距而改變其大小。 固定前鏡頭固定前鏡頭在變焦及/或對焦時不會轉動,故可容許攝影師用花瓣狀遮光罩,固定前鏡頭能更容易利用極化濾鏡。 無天氣密封天氣密封鏡頭可防止塵埃及水份浸入。當鏡頭不是防水的,此類鏡頭可適用於下雨及朝湿環境。有些密封只可防水或防塵。天氣密封只適用於類似天氣密封相機內。 無插入濾鏡支援插入濾鏡使用於那些前鏡頭過大或視野不容許於鏡頭前傳統濾鏡的鏡頭。通常遠攝及超廣角鏡頭支援這類濾鏡。 |

This lens is a newer version of the standard kit lens that comes with E-series Olympus digital SLRs. It is about 1/3 smaller in length and girth and weight than the 14-45 lens. It has the same apertures (3.5-5.6) as the old one but focuses a little closer. The first thing I noticed is that manual focusing is quicker, quieter and more positive than the old one. It has the feel of a "good old" prime lens when focusing manually. The smaller size really helps it fit in my bag better; the lighter weight makes carrying the camera (E-330) much easier. A fine point: Olympus now supplies a front-pinch type lens cap that makes it possible to remove and replace the cap with the lens hood in place. The previous model had an edge-pinch type that made it necessary to remove the lens shade first. The technical reviews suggest that this lens produces images that are sharper in the corners at full aperture than its predecessor. But what I do know for sure, is that although the near-focusing distance is about 1 foot, I was able to produce a sharp image (in Macro setting) at 5 inches on my E-330!! The mounting bayonet flange appears to be plastic. Only time will tell about its durability. I don't do a lot of lens changing, so I'm not concerned. The images I'm getting are excellent, so I'm glad I made the change. Recommended.

Pro: Very sharp for a kit lens, very light, very small. Good focal range (28-84mm full-frame equivalent), really well built for a plastic lens
Con: plastic mount, not that fast (5.6 at the longest end)
This lens is so light and small that even if you have better ones, you should still have it in your camera bag as a backup. As a primary "walk-around" lens, it's more than up to the task.
