I have read user comment that the coating on the shell did peel off, but I haven't use Sigma for many years so I do not know. However, I know that poor flare control remains one of their major problem. This is particular annoying with wide angle lenses. |

In fact, Sigma is still making poor coating on there lenses.
Unless you must use that range or aperture lens, avoid Sigma.

In general, Sigma's selling point are good in pricing and photo quality (in some lens). However it has no second hand value.
Peeling off the coating is a problem but only affect the lens appearing not the photo quality. It has no second hand value anyway.
As you're looking for a 定焦 lens, why don't you consider 正廠lens as the price point are not that big in different? Of course, neither Cannon nor Nikon have aperature 1.8 at 20mm. They only offer 2.8.
I havn't tried 20/1.8 but I have 17-35/2.8-4. Well, photo quality is surprising me especially the aperature open at f5.6 or above.
When 焦距 set at 17mm, distortion is obvious at the photo edge.

Yes, I highly recommend fixed focal length lens!!

Several years ago, I also have a sigma 15/2.8 fisheye for my canon EOS. Yes, it has flare but the price is reasonable. In terms of quality, sigma is not recommended but if you just want to have the felling of fisheye, you can buy it for playing. |

其實Sigma 鏡的最大問題是那鍍膜容易變質的問題. 那變質的問題到現在也未能解決. |

就算Sigma的鍍膜會變質，正常用兼唔係次貨既話，用你三、五年無問題卦？OK！再睇睇價錢，就俾你用三五年哩，都抵啦...下話？原廠鏡貴幾倍，咁就係咪會長返幾倍命先？（我就覺得未必羅。）仲有，Sigma鏡平咁多（尤其EX系列與原廠同級既鏡頭比），有咩碰碰撞撞都無咁肉痛，大家睇睇的記者，幾多用Sigma鏡，反正佢地用鏡無耐就殘哂，何必買咁貴者？爛左咪買過枝羅，又唔係貴。咪一樣都係羅去「劈」！有乜分別？
況且，Sigma既光學其實唔差架喎，佢幾枝EX係重頭鏡既解像度拍得住原廠既喎。而且佢有好多鏡的焦段都好獨特得來又好用喎。所以大家唔好將Sigma彈到一文不值。
如其間中用枝好耐用既鏡頭影少少相，不如成日用枝唔係咁襟既鏡頭影多的相好過啦！ |

幾同意bus fan的意見.如果o下o下都同原廠鏡,好鬼甘,仲有好多原廠唔出o既焦距,副廠都會出 |

可能買Sigma的人都認為Sigma用兩、三年就完了，所以就很"粗用"，引致有大量這種問題出現。原廠鏡價錢貴一至幾倍，當然會加倍愛惜，不會亂操。 |

我想先講在畫質方面的問題，我成日都同人講，你買本Leica特集，同本Sigma的影集看，你看得出有何分別嗎？不是同一地點、光圈等相同條件下一齊拍攝及放大，很多時是看不到有何差異，就算真的同時拍攝，又未必個個分得出，首先我再聲明本人絕對相信Leica的威力，請各位Leica人不用護架，我這樣說是想說很多情況下，我們是很難看到當中差異，當你能分辨出亦好自然咁唔會再買或再睇所謂副廠鏡，再說很多人說不耐操，我記得我十年前買了枝Sigma 28-70mm f/2.8我是很常用的，大約一年多拍了400筒菲林，鏡頭的麼打壞了，現在用28-70mm f/2.8L，兩年拍上千筒多了，未壞，但也因虛耗驚佢壞而買了換了枝一樣的鏡，所以我覺得你如果成日影，咁一年壞左都抵啦，返正你買枝貴鏡，咁用法枝鏡未壞你都一樣會換的了，好多人買好靚好貴既鏡頭當佢貢品咁，拿出來影張相又搵個套包番住佢，錫野唔係唔對，但記住鏡頭係愛黎影相既，唔係愛黎招呼人客既，招呼人客用你的相片，我想會好很多，現在我仍有玩副廠鏡，圖麗，騰龍、Sigma都有用，自己鍾意咪得囉，返正要自誇的應是你的作品，而不是你的器材，不過我成日比人話我偏激的，所以自己過濾啦，祝你買到枝鏡後，好好的用，不要祇顧望住人地的鏡頭。用得好就係好鏡，用得唔好就即係浪費。 |

同意樓上幾位的說法. 由於本身沒有太多錢, 所以早前只好買了支Sigam的70-200mm F2.8 HSM, 初時還戰戰競競, 很怕這支的質素和耐用度不夠, 到頭來只是賠了錢紙得個桔. 但是, 用了幾次, 拍出來的相也很滿意, 解像度很好, 顏色也很自然, 而且對焦又快又靜. 有時候看過由原廠拍出來的相, 可能我只是一個初學者, 我看不出有太大的差別. 至於耐用度, 我只是用了幾次, 不能多說一二吧!
其實, 我並非有意挑起品牌之爭, 只是覺得像Sigma和Tamron 等的副廠, 他們有時候出的鏡頭真是很好用. 而原廠鏡頭的售價, 有時候對於像我們這些窮等人家來說, 真是望而卻步. |

其實講真心，原廠和副廠質素係有分別，但好多時候買原廠鏡，係比客睇的，所以自已玩如果追求質素不如買120，貪方便自己玩就玩副廠好啦，最近目標是Sigma的100-300mm f/4，希望到時有機會黎個副廠攝影行山團，hehe。 |

I think in most situations, only when you are shooting digital photos and view them at 100%, you can easily find the differences between a Sigma and Canon. |

An naive assumption. Many very old manual focus equipments have been heavily used for many years and still working, even thought they looked absolutely ugly. I have never abused my equipments but the Sigma products that I had couldn't stand years of light use. Well... not that mean years actually. In 2 years time, my MF24/2.8 showed worn electrical contacts, worn rubber coating, worn focus ring rubber, worn plastic aperture ring. It was obvious that Sigma chose to compromise on quality for quantity. I am not saying they were wrong. But when one buys into Sigma, they should at least realize what they are buying into. They are good choice if one is on very tight budget. But if one can afford something better or looking for long term investment, don't waste money on Sigma. |

Press photographers are the minority. They do not represent most photographers, not even close. Not everyone purchased their equipment 羅去劈 (I don't know why the average photographers would want to do that anyway unless they tried to pretend to be professional press photographers). When buying expensive lenses, you are buying many quality. Built quality is only one of them. My opinion is that 性價比 means nothing in reality. This term was created to fool people because one cannot compare them based on price alone. Poorly built super cheap products would also score the best based on the 性價比 term. We all know high quality products are much more expensive to manufacture and often costed a few more times than low end products. One cannot assume double the cost must double the quality (only the boss would expect this from their employees).
>況且，Sigma既光學其實唔差架喎...
If this opinion is based on how many stars they scored from the test results, you are being fooled. Many lenses score high on resolution tests but in reality, they aren't that great. I am not saying EX lenses aren't good, but have you compared EX lenses with other high end lenses to draw this conclusion?

How about "用枝好耐用既鏡頭影多的相"? |

Well, you paid what you got. All company are going to make money by there products and you paid for their livings.
Sigma owning good resolution and contrast in certain extend. But, the built quality (not the finishing) is ugly to me. My APO 400/5.6 has glass fog and Sigma don't have stock to get it repaired. An old friend of mine has an aperture blade dropped in his newly purchased Sigma. There are many many failure report from all kinds of defect, and it is the fact of Sigma.
I purchase 3rd party lens base on original one is either too expansive or not in production. If there is original brand one, save more to get it.
By the way, many of my old cameras and lenses are more elderly than me, they still working good. And I forseeing that my Pentax are working great within my lifetime. I never think that buying a lens just working for a few years.

可能我們都是先入為主，認定Sigma鏡就是不耐用，鍍膜易變質。事實上可能有用上十年八年的大有人在，而我們就只記得壞的地方，也聽得太少好的反應。
"副廠平鏡粗用，正廠貴鏡加倍愛惜"的大有人在，是否"naive assumption"？可能"七三"吧！但我心裡有數。
現在用副廠鏡擔心的是，新出品的機身對副廠鏡的兼容問題。買鏡時要加上機身升級作考量。
