Flower Patch (2) — by Anastigmat Lens


The shot from the same flower Patch as before but by the 100 year old 

German Anastigmat Lens.  There was no fancy operation or trick, but just

click a DSLR Canon 5D on AV mode, while the lens was fully open F5.4.

(Focus was done by a Pentax Helicoid Extension Tube)





On this last picture, there are funny halo on the whitish flowers = almost like

a Focus-Shift or Lens Vibration though they were only a straight shot if not

by a hand blurr (but not likely) —– I’m not sure what caused it.  The 100 year 

old lens has no crisp image still able to show certain details but nothing more.

      Thank you Bente. In fact, I wished if I had or able to access the real
      optical test facility, I could have much more scientifically precise analysis.
      (In japan it would be easier = as 80% of all the camera came from there,
      naturally I could easily find and ask the people who got the facility.)
