Re: Is Canon EF-S 18-135 STM lens too soft in large apertures?

I just bought Canon 70D with 18-135 STM (Kit)

Guess what, I did extensive experiments and here is what I concluded:

18mm - Horrendous front focusing issue.

Gradually reduces to almost none by 100mm.

Micro Focus adjustment that seem to fix it:

Wide: +5

Tele: 0

Try taking a picture with 18mm in room with objects in range approx 3 ft. all the way to 14 ft.

Focus (Use single center focus only) on farthest object.

Viola!! The image focuses best on the object that is close to you. It sounds ridiculous but almost 4-5 ft object is in focus.

SHAME on Canon!!!!

Did I say S..H..A..M..E... on Canon !!!!!!!!!

Why? Because I might be ok to live with this Microfocus Adjustment only if it worked in all modes.

No, it does not work in any "Auto" mode. Only works in P,Tv,Av,M Modes.

Guess what, the kit is going back!!
