I checked today. The best focus i can get is when i turn the focus a little past 0,66m towards infinity mark. After that the picture in the EVF becomes more and more blurry.

And as you can see from the picture above that is probably the best i can get at f/5,6.

I am really concerned about the corners, but also in the middle of the picture i dont get enough depth.

Can this be fixed with your method or should i complain to Venus optics? I bought it directly from them.


Sorry for the delayed response. And thank you for letting me know by writing on my blog. Judging from your picture, your corner seemed very blurry and a bit unusual. My lens does get soft at f/2 on the corners, but at f/2.8 and smaller, the corners look fine. I don't think this problem is solvable using my spacing method. If you can contact them for a replacement then that would be great.

My spacing method will only solve the lens' inability to focus to long distance objects or to infinity.

Hope this helps and once again sorry for the delayed response.
