Lol at its the glass. It certainly is not. It's the processing and web sharpening. That's all.
For the web stuff, I agree the sharpness is in the processing; but I've used high end glass on high end cameras from both Canon and Nikon, and I assure you there was a difference to me. Canon glass was more clear, realistic, vibrant and crisp when comparing the exact same shot from both. Of course, this test of mine was 5 years ago. So, that may have changed in the past few years. They may be neck and neck today, but I was serious as to why I chose Canon. The only thing that attempts me to swap from time to time is Nikon's raw sensor color and Canon's dumbass issues. lol
