想請問各位有買這兩顆鏡頭的前輩，我想要為D50添購超廣角鏡，請說說看兩顆鏡頭的表現：
1. 各焦段下的色彩表現如何？
2. 廣角端(10、12mm)的畸變控制情況，在不同光圈下的銳利度與四周邊緣鬆散的情況？
3. 在抗耀光性的表現如何？
4. 拍夜景的表現如何？
5. 搭配哪一牌的UV與CPL後廣角端的暗角情況如何？
6. 對焦速度的表現如何？
7. 鏡頭的耐用性如何？鏡頭的質感與外觀如何？
就以上所述幾點，各位大大可以貼一些圖給我們想買的人很好建議，或者推薦一些不錯超廣角鏡的各方面表現，謝謝！!

kuankuoyun2002 網路會員	4) 2005/09/21 12:44 Re: 12-24mm wich one to choose : Sigma - Tokina - Nikon 1. Tokina 12-24mm F/4. I have this one and very happy with it. it's built like a tank and razor sharp! even at wide opened, Someone here in the forum think it sharper than the Nikon. Noticeable CA but if open image with NC, it will be hard to see it. Little to acceptable distortion, and good contrast 2. Sigma 12-24mmd f3.5-5.6. I used to own this lens. it's huge and bulky, soft at wide open, can't scew in a filter in front! can be use with FF body. I exchanged it for the Sigma 15-30, very sharp but I can't live with the gel type filter and sold it for the Tokina. 3. New Sigma 10-20 F4.5-5.6. Lot people with possitive with this guy, there are nice sample on this forum. if you refer 2 extra mm rather than constant F/4.you could be happy with this lens. 4. Tamron 11-18, I've seen sample with lot CA, distortion. http://forums.dpreview.com/forums/read.asp?forum=1030&message=15040879
kuankuoyun2002 網路會員	5) 2005/09/21 12:53 It is prone to flare - it could hardly be otherwise given the wide field of view and that bulbous front element - but a little attention to shadling the lens with a had or a book removes that one. Where this is not possible, some flare may occur. The one below was taken with the sun just out of frame, though I have partially cloned over the two flare blobs which resulted. Colour rendition, given the field of view, is also very good. It does soften a little at the wide open end and is happiest aroind f7 to f11, but the detail is in fact there - a touch of sharpening brings it back nicely. Its one major failing is the difficulty of using filters - you can fit 82mm ones into the adaptor but it will vignette shorter than around 17mm. I cannot speak for the others apart from the Nikon, which we rejescted as (a) its level of architectural barrel distortion was unnacceptable, and (b) we felt the Sigma was every bit as good, but half the price - and it's a riot of a full frame body!!

kuankuoyun2002 網路會員	6) 2005/09/21 12:54 I recently bought the Tokina 12-24mm. I really wanted the extra 2mm of wide angle with the Sigma 10-20, but even stopped down with manual focus at infinity the background was quite soft with the Sigma I tested at the camera store on my camera. What I finally boiled down to for me was I would rather have a sharp 12mm shot than a soft 10mm one. -- Brent http://forums.dpreview.com/forums/read.asp?forum=1030&message=15048557
morlinyu 網路會員	7) 2005/09/21 13:00 Sigma 10-20(在10mm端)真的與Tokina 12-24(在12mm端)銳利度差很多嗎？有Sigma 10-20的大大可以說說看你的使用新得，謝謝！!

kuankuoyun2002 網路會員	9) 2005/09/21 13:04 Couple of test shots from Sigma 10-20 at 10mm The lens seems to be very soft at 10mm, at least the sample I got. First shot - f9.5, second - f22. Tripod, remote, RAW, no postprocessing (no in-cam shapening). 100% crops directly from NC (jpeged as "excellent quality). http://forums.dpreview.com/forums/read.asp?forum=1034&message=14725110
kuankuoyun2002 網路會員	10) 2005/09/21 13:08 Vignetting and Sigma 10-20mm Trying to understand the dark upper left corner in my Sigma 10-20 IR shots discussed in: http://forums.dpreview.com/forums/read.asp?forum=1030&message=14666124 Or just look at this 10mm IR image: http://forums.dpreview.com/forums/read.asp?forum=1030&message=14677652
kuankuoyun2002 網路會員	11) 2005/09/21 13:09 20mm worse than 10mm Just realized vignetting of my copy is worse at 20mm (than 10mm). This explains why the 20mm IR shot has more serious upper left corner darkness than 10mm shot. 20mm IR http://forums.dpreview.com/forums/read.asp?forum=1030&message=14678155
kuankuoyun2002 網路會員	12) 2005/09/21 13:12 sigma 10-20 does have some vignetting Got my 10-20 today at 4:00 p.m., and of course, it was drizzling all afternoon. I only got 5 minutes outside this afternoon and about 4 minutes outside tonight before some light raindrops started coming down. Oh well, will be fun to play with tommorrow. Generally I like the build of the lens. The only thing that I'm a bit disappointed with is the degree of vignetting which is quite noticable: Here is the sigma 10-20 on my d100 with a test shot of the sky, 10mm at f/6.3, 1/160 sec. http://forums.dpreview.com/forums/read.asp?forum=1030&message=14591694
