[APML] OT: for sale, Pentax 67 1.4x rear converter

[Wei-Hao Wang <whwang@gmail.com>]

Hi,

I have a Pentax 67 1.4x rear converter for sale.  I bought this from
Matt BenDaniel
about two years ago. I didn't use much so I decide to sell it.  It's
still in perfect
condition.  

These are three pictures taken with this rear converter:

Matt said that he notices some internal reflection from this rear converter when
he shoots the moon.  I don't have such a problem since I'm only
shooting deep sky.
The image quality at the field center is excellent.  I can see
diffraction rings with
I focus with a 60x microscope.  It's not as sharp at the corners of the 67 frame
but is acceptable.

Let me know if you are interested.
