Wide is Wide!!! I am a noob and wish I would have done a little more homework before trying to find the perfect wide angle instead of buying them all at once so if your a noob and have questions about any of the lenses listed in this review please hit me up. Below are pics taken at distance from the subject with same Canon 5D Mark II, keep in mind on a cropped sensor camera these pics will not appear nearly as wide. let me show you the ranges of each, the primes are fixed of course but I shot the 2 zooms at their widest points. I hope this helps someone make their choice a little easier instead of outright buying all of them at once, let me save you some trouble. Please if you have any questions on performance of each and your thinking about picking one up hit me up, I can tell you how I like them. I am not selling any of them just trying to help a fellow photog out... EF 15mm f/2.8 Fisheye, paid $649.00 @ BHphotovideo.com EF 17-40mm f/4L, paid $750.00 @ BHphotovideo.com EF 20mm f/2.8 USM "Super Wide Angle," paid $469.95 @ BHphotovideo.com EF 28-135 f/3.5-5.6 IS USM paid $409.95 @ BHphotovideo.com Does anyone have any advice for me??????? What lenses am I missing in my lineup???
