hector_evans Posted July 7, 2008 Share Posted July 7, 2008 I have the 28-135 IS which I use with my 400D. I noticed that it is very soft at zoom extremes, especially at 28-35mm. Is this something I should expect of this lens, or should I look for the fault somewhere else? thanks Link to comment Share on other sites More sharing options...
adam_gifford Posted July 7, 2008 Share Posted July 7, 2008 I have this lens on a 300D and I haven't noticed anything like that. Do you have any example pictures that demonstrate what you are seeing? I've mostly been frustrated by 28mm not being wide at all on a crop camera :) Link to comment Share on other sites More sharing options...
ralph_jensen Posted July 7, 2008 Share Posted July 7, 2008 The 28-135 is one of Canon's most underrated lenses IMHO, a very solid performer. Though nothing close to a prime at zoom extremes, it is supposed to be pretty good in the 28-35 range. So "very soft" seems not right on a crop camera like the 40D. Best thing to do is read non-photo-magazine tests and see whether their experience differs from yours: http://www.the-digital-picture.com/Reviews/Canon-EF-28-135mm-f-3.5-5.6-IS-USM-Lens-Review.aspx http://www.photozone.de/Reviews/Canon%20EOS%20Lens%20Tests/45-canon-eos-aps-c/190-canon-ef-28-135mm-f35-56-usm-is-test-report--review Link to comment Share on other sites More sharing options...
charlesking Posted July 7, 2008 Share Posted July 7, 2008 I've used this lens for a couple of years, and it does tend towards softness at the edges when wide open, but I have to look for it and it's often not noticeable. It's really a medium-to-long zoom on a crop camera. Link to comment Share on other sites More sharing options...
tommyinca Posted July 7, 2008 Share Posted July 7, 2008 Its normal. This lens is softer at 135mm f5.6. My copy is good at 28mm with a little of softness at full frame corners. Link to comment Share on other sites More sharing options...
g dan mitchell Posted July 7, 2008 Share Posted July 7, 2008 No zoom will be equally "sharp" at all focal lengths, especially at the largest apertures. Link to comment Share on other sites More sharing options...
tdigi Posted July 7, 2008 Share Posted July 7, 2008 I did not care for the lens in question. I know many people think very highly of it but I thought the photo quality was just average at best. Link to comment Share on other sites More sharing options...
dan_hall4 Posted July 13, 2008 Share Posted July 13, 2008 Stop it down a bit and see if that helps. Try the f/8 to f/11 range. I had one and got some great shots with it. Also, be sure to use a tripod. That helped me more than anything. The 28-135 is a very capable lens. Link to comment Share on other sites More sharing options...
