Lens Test on Cherry and Plum Blossom

TEST-01-A09A6563

Those photos were taken a while ago, the same day I took pictures of Daffodils.

(After this, there must be much better full bloom somewhere else though.  🙂 )

(photo above was taken by a Canon Fisheye lens)

TEST-02-180-002

And the following photos were taken by the Two Element Homemade Lens above.

The beauty of this lens was that there is no focus  😀   (Other than this lens,

rest of the lenses were used with the Tilting Macro Bellows for focus.)

TEST-05-295-001

And the following photos were taken by a lens originally came from a Canon

compact camera G9 = it was their zoom’s front element.

The lens was Epoxy glued onto a lens mount ring and a filter ring was fixed too.  

TEST-06-A09A6621

TEST-07-A09A6577

TEST-08-A09A6622

Unlike first two photos, those photos were (I think) Plum tree.

TEST-09-A09A6627

TEST-10-A09A6628

TEST-11-A09A6614

Next was a front element of a Zoom lens  (I don’t remember where it’s came from,

Canon or Sigma ?)  — The lens was fixed in a similar way to the other homemade lens.

TEST-12-297-001

Front element itself couldn’t eliminate the aberration. —– but this one showed

very strong Coma aberration — (if not a camera shake).  In most of the case,

good softness of the image was created by the Spherical  aberration  

= so, Coma aberration was not desirable here.

TEST-13-A09A6580

Strangely, this Coma aberration appeared somewhat in middle distance.  

TEST-14-A09A6581

And not much so on the close-up.

TEST-15-A09A6638

This one above showed no Coma aberration but the following one did  ? ? ?

TEST-16-A09A6633

Test-17-A09A6634

I need to have more test.

TEST-18-296-001

Last one here came from a cheap Wide-Converter for a compact camera.

It got quite big diameter — hence the effective F-aperture is F1.6 !

TEST-19-A09A6592

 

TEST-21-A09A6593

TEST-20-A09A6594

I like the images from this lens though —– strangely, despite full open F1.6,

the back image was not necessary out of focus or dissolved into big  Bokeh.  

TEST-22-A09A6589

TEST-23-A09A6596

Anyhow, each lens got its own character = pros and cons.  🙂

TEST-24-A09A6597

Last photo above was again by the same Fisheye lens.
