I have one of these lenses andf it’s either faulty at point of purchase or it’s jut not as sharp as it sould be, specially for the price!
Extremely disappointed with this lens. Poor focus after 15′, Images never sharp under any condition. Not at all what you would expect from an L series. Lots of $$$$ poor performance. Working on third copy. Unfortunately did not get chance to evaluate prior to warranty running out.
CAUTION!!!!
PS failed to research product reviews prior to purchase, My Bad, Better luck to all!
I’m an amateur photographer with limited skills. I bought this lens to use to shoot waterfalls and other landscapes. I’m very pleased with it.
It’s a great lens with a terrific picture but when it is extended for the widest angle shots the extended part of the lens blocks part of the built in flash from the Canon EOS cameras. It won’t be a problem if you use an accessory flash like a speedlite but it will be a real problem with the built in flash. Most of my flash photographs have a nice dark arc without light because the lens blocks the flash. If you are going to spend that much for a lens you should know it will be a poor buy for photos with your built in flash.
First, I am an amateur. I purchased this lens because I am going to start taking my photography much more seriously and decided to get a good lens right away since I had the funds.
I find that my lens doesn’t seem to be as sharp and crisp as I’d like. My old G5 shot sharper photos. I’m using an EOS 30D body. I’ve take about 2,000 photos with every imaginable combination – auto focus, manual focus, zoomed in, zoomed out, inside outside, built in flash, EX-580, diffuser and so on. The photos look nice, but not sharp. Edges are always seem soft to me.
Is there a known defect in this series with certain makes? I understand that this lens has a short depth of view, and have accounted for that. I am seriously considering returning this lens for the f/4 is 24-105L. Being an amateur, I do want greater depth, especially at close range and I wouldn’t mind something a little lighter.
Is it simply a matter of me needing to learn more and that this lens will eventually live up to it’s reputation? I am a picky person, but I don’t think I am being overly picky in this case. Like I said, my G5 takes sharper pictures. Thanks for any advice.
*EDIT*
I may have found a solution and will test it further later. I bought my 30D with the lens and this is my first round with DSLRs. I moved the dial to the user selectable dials and the menu options are different than in the auto setting dials. The last red menu item (can’t remember what it’s called) is the portal to more manual user settings after pressing the “Jump” button. From there, I was able to adjust the sharpness from the default to the max. It improved the sharpness of the photos a lot. There are also settings for saturation, contrast and a couple others. I’d like to test it out on people before making final judgement.
I still wish I could make the auto settings sharper, but being how this is DSLR, the auto functions really aren’t what I bought this for. I’d still appreciate any input/advice from the pros.
