I remember that the Canon EF 24-85mm f/3.5-4.5 USM lens was released at the same time as the EOS 50 film camera. The silver version is a kit lens that comes with the silver EOS 50 body. The second-hand price is around NT$4,000-5,000. The focal length is the most common 24-28-35-50-85 on full-frame cameras, which is equivalent to 38-136 on APS-C cameras, making it a slightly telephoto zoom lens. In terms of image quality, the soft feeling when opening the aperture seems to be magnified a lot on APS-C bodies. It is significantly improved when the aperture is reduced to f/8. According to my research on the internet, the image quality of the full-frame body is said to be better than that of the APS-C body. For full-frame cameras, there are three 24mm-start zoom lenses available. If you have a limited budget and can't afford the 24-70mm f/2.8 or 24-105mm f/4 IS, this lens should be your top choice.
Canon EF 24-85/3。5-4。5 USM 這顆鏡頭印象中是隨著 EOS 50 底片機上市一起發售的。銀色的版本是搭配銀色EOS 50機身的 Kit 鏡頭，二手市價約 4000~5000台幣。焦段是全幅機最常用的24-28-35-50-85，在 APS-C 機身上等同焦距 38-136，可當作稍望遠的變焦鏡頭。論成像品質開光圈的鬆軟感覺在 APS-C 機身上好像被放大了不少，光圈縮至f8則有明顯改善。網路上爬文結果，全幅機身的成相品質據說是比 APS-C好一些。針對全幅機，24mm起跳的變焦鏡有3顆，如果預算有限買不起 24-70/2。8，24-105/4 IS，這顆鏡頭應該是首選。

I haven't been to Sanxia in a long time. The last time I came, the Minquan Old Street hadn't been renovated yet. Now it's been completely restored. There are several specialty shops that shouldn't be missed, such as Kangxiyuan's Jinniujiao and Chashanfang's floating soap. However, my favorite is still the streetscape of the old street. Whether it's the broad streetscape brought by the wide-angle lens or the compression effect of the telephoto lens, the geometric beauty of the old buildings is like a painting.
很久沒有到三峽了，以前來的時候民權老街還沒有整理，現在則是煥然一新，幾間特色商店
如康喜軒的金牛角，茶山房的浮水皂。。。等等都是不能錯過的地方。不過我最喜歡的還是老街的
街景，不論是廣角鏡頭帶來的寬闊街景或是望遠鏡頭的壓縮感，老建築的幾何之美彷彿化身
成一幅一幅的畫作。
