No luck again: 18-55 IS vs 17-55 IS problem again
Jul 30, 2010

Hello,

This is the second 17-55 I had bought. I hoped I can make razor sharp pictures - as lots of user suggested it as a better solution than a 18-55 IS.

I bought a new 17-55 IS today, and I had compared with my 18-55 IS. I am using 7d body.

I am not impressed. The 18-55 IS much sharper AGAIN. No I haven't tried microadjustment, because I expect some quality from a 1000+ usd lens.

1. 18-55 IS at 18mm:

2. 17-55 IS at 17mm:

3. 18-55 IS at 55mm:

4. 17-55 IS at 55mm:

What do you think ?
