Im going to have to do this slowly as this is a very interesting lens , that needs some delving into ..
@ 105mm it has that GLOW / hue , halo effect when close ( 1.5meter minimum focus - Normal ) and when using the close focus function ..
Not so much an issue @ 35mm , in fact , 35mm is some what impressive ..
Lets look at the lens ..

No 1 - Your f stop ring or aperture ring
No 2 - Zoom ring
No 3 - Close focus ring
No 4 - Focus ring
Now you can use both the focus and close focus rings , this is very nice , the close focus is some what of a course adjustment , while the normal focus ring is very fine , or large amount of movement to go in and out of focus ..
There are only 5 aperture settings , 3.5, 5.6, 8 , 11 and 16

This is a somewhat large and heavy lens , I mean , its a brick .. And in front of the little istDs , yeah , you can feel the heft !
Now lets check out what happens close up @ 105mm
http://i1033.photobucket.com/albums/a420/old4570/IMGP7508_zps8c85a48b.jpg
This picture was taken @ 105mm and f3.5 just outside ( few centimeters ) the minimum focus distance ..
In the next images , we will examine the close focus , now the exact same thing happens using the close focus as taking pictures @ 105mm just outside the minimum focus distance , so why double up ?

Thats @ 105mm
Next lets take a look 35mm , here are some images @ 35mm just to see how close you can get at this setting ..

Well , its a dark dreary day outside , but at 35mm and f3.5 , hand held mind you , the lens is working rather well ..
I went outside to take some more pictures - unfortunately the weather is a little topsy turby outside .. The sun came out as I was taking the pictures , and you can clearly see how this affected the images ,
but we are examining the halo or glow .

First image @ 35mm and f3.5 using close focus
http://i1033.photobucket.com/albums/a420/old4570/IMGP7573_zpsc4d2507a.jpg
Second image - f5.6
You will note the lack of the halo or glow effect , unfortunately at this point the sun began to peek and the wind picked up ( very poor conditions for testing )

Third image - f8

Fourth image - f11
http://i1033.photobucket.com/albums/a420/old4570/IMGP7576_zpsf558c102.jpg
Fifth image - f16 and the sun is blaring down
Now next I went back to 105mm and f3.5 to see what effect moving away from the subject would have ...
First shot is about 2.5 meters ..
http://i1033.photobucket.com/albums/a420/old4570/IMGP7579_zps6eee8cb6.jpg
Now the problem here is the wind , the subject is moving , and the wind is only growing in strength , so there might be some BLUR in effect from movement ..
In this next image we are still @ 105mm and f3.5 .. My focus point is the pin wheel ..
http://i1033.photobucket.com/albums/a420/old4570/IMGP7584_zpsa1a147af.jpg
Now will notice the limitations of f3.5 in this image , again be mindful that the wind is in effect : And its going to be a few days before the weather settles ..
So I will come back to this lens , this is a very interesting lens , but for now , mother nature wins .
