HC100mm + 52mm Extension Tube

[meshuggener]

Hi !
I just bought a 52mm ext tube to do some macro. I was surprised of the bad quality in the corners, at full aperture but even at f8. Has anyone noticed that ? Ok, I don't need f2.2 for macro but f8 is not as good as I thought it would be.

Here are some exemples :

f2.2


f8

Yes, I think this is definitely a portrait lens. Why not try the 120 Macro II?

I wish I could ! 
I should sell my 50-110 and buy a 120...
