Below you’ll find out, as I did, that contrary to reviews<\/a> on the net, the 28-135<\/a> wasn’t as bad as they said it would be.<\/p>\n\n “Reviews on the 28-135 IS USM”<\/p>\n “Canon EF-S 18-55mm f\/3.5-5.6”<\/p>\n “Canon EF 28-135mm f\/3.5-5.6 IS USM”<\/p>\n “Canon EF 50mm f\/1.8 II”<\/p>\n “view original file”<\/p>\n “view original file”<\/p>\n “Canon EF-S 18-55mm f\/3.5-5.6 details”<\/p>\n “Canon EF 50mm f\/1.8 II details”<\/p>\n “Canon EF 28-135mm f\/3.5-5.6 IS USM details”<\/p>\n The sample pictures comparing the 3 lenses were shot from our window, down to the condominium grounds, taking shots of “car detail and whatnot” of whatever the view provided. I tried my best to find which settings could be “compared.”<\/p>\n These were taken at approximately 2:00pm (+8 GMT) with natural outdoor light. To make sure the testing environment was controlled, I went as far as putting a marker where I was supposed to step on, which part of which car to focus on, and how I leaned on the concrete.<\/p>\n Feel free to check the EXIFs on each original<\/em> picture (linked), but here’s the information nonetheless:<\/p>\n The pictures output were 24-bit 3072×2048 JPEGs (large setting) and the only post processing tasks done were level adjustments (and cropping for the examples you see in this blog). 50mm at 1\/80 and f\/8 in that lighting environment were obviously underexposed. So I just equalized the levels, making sure that I wasn’t affecting edge contrast in any way.<\/p>\n The three original (level-adjusted) photos can be viewed here:\nWARNING: large files<\/strong><\/p>\n NOTE: Image Stabilization on the 28-135 was NOT<\/em> used for the objective tests above<\/strong><\/p>\n The cropped images are at 100% resolution and not resized in any way. Since I was after objective comparisons of sharpness, I chose the plates of the cars, where the edge contrast of each lens was apparent. here’ they are in cropped 300×300 pixel samples.<\/p>\n As you can see, the kit lens, is the worst of the lot (that’s not to say it is a louse lens of course, and the 1.8 prime having the best edge contrast among the three.<\/p>\n Here’s another batch of cropped areas from the full-res pictures:<\/p>\n Again, similar results. At this point of my tests, a sigh of relief now swept over me as I thought “this was indeed the right decision for me.” So I now wanted to test the Image Stabilization (IS) feature, and here’s what I got. Used the same settings as above with these differences:<\/p>\n As you can see, the 28-135<\/a> is spectacular considering the reviews circulating the internet.<\/a> I guess those having negative feedback about this lens were indeed either used to L-lenses, or people simply comparing it to better, high end lenses<\/em>.<\/p>\n The 28-135<\/a> is a decent lens and definitely better than the kit lens.<\/a> With a great zoom range and simple macro capability, it is indeed a good single-lens replacement for the “budget-hobbyist.”<\/p>\n The only drawback I guess would be the slower AF, and sometimes downright irritating AF in low-light. Howerver even the prime<\/a> lens seems to be suffering from this problem so I guess it’s a trivial matter.<\/p>","protected":false},"excerpt":{"rendered":" “Read post” “Reviews on the 28-135 IS USM” “Canon EF 28-135mm f\/3.5-5.6 IS USM details” In my previous post, I mentioned adding a couple of lenses to make my life easier.
