Want to know the brutal truth about Canon camera lenses?
They're far from perfect........... but then again, so are ALL the other lenses made by other manufacturers. The truth is that with the purchase of a brand new lens comes the possibility of disappointment. With a new lens, it's a very tiny possibility, but it's there.
Advancements in lens design and manufacturing have come along way and we are living in a remarkable time in the history of photography. I hope you are enjoying it.
As a typical human being, I am far from perfect, although I like to believe that I still have some value to offer. Lenses have more imperfections that I care to learn about, but here is the point I am so desperately trying to make in just the right way:
It's only the imperfections that can be noticed that matter.
The defects you can't see don't really matter, do they? Seriously, if a slight chromatic aberration, or a minor lens flare, or a 7% decrease in contrast at the corners can't be noticed, should you be concerned that a technical lens test revealed it?
If you have a small barrel distortion and you don't notice, has it ruined your photo? I'm not so sure.
Photography is an art and I sometimes still catch myself getting to focused on the technical stuff. Yes, it is important to get the best equipment and accessories to help you get the best photos.
Just remember, it's not the size of the magician's wand that counts, it's the skill of the magician that matters most.
The hard work that lens testers do is important and valuable. The methods they use, the testing equipment they employ, and the significant time they invest all add up to scientific data that can be interpreted for evaluating lenses.
So my next comment is meant with no disrespect intended. Your own tests are so much more important than the test done by the professionals. You need to please yourself first and then the people who are viewing your photos.
The simplest thing to do is to test a lens yourself. You can even use an affordable lens test chart if you;re serious about testing.
The third step is very important. While it may be true that a high percentage of the photos we take don't become large prints, get published in magazines, or used for billboards, we do want to examine them closely when we are testing a lens.
When you buy a lens and match it to the same brand of camera you should expect a perfect union, both in terms of communication and optical performance as well. If your camera-lens combo aren't "talking and listening" properly, you've got a serious issue.
Their performance together can vary. Just like every shoe doesn't fit perfectly on your unique feet. Yes, I know cameras models are much more uniform that are our feet, but you can get the point, I hope.
There are tiny differences in focal distances or camera mounts that can affect focusing points, particularly at wide open apertures where depth of field, and depth of focus are so narrow.
That's just my opinion on the truth about Canon camera lenses. If you want to share your opinion on lenses, I'd love to hear from you.
Watch less TV. Shoot your Canon instead!
Unfortunately, it's often a lack of knowledge or poor technique that causes consumers to complain about lens sharpness or focusing issues.
About 2% of new lenses will truly be "defective." Whether a lens was banged around too much in shipping or there was a blip during it's birth, it could be a bad one.
