I found a solution for the double adapter mistake that results into that Image stabilization isn't working with Pentax 645 lenses on Fujifilm GFX cameras. Because I use the electronic Finger EF-GFX adapter - together with an additional Pentax 645 to EF dumb adapter. THAT confuses the camera due to the electronics in the Fringer EF-GFX adapter.
So, i use a piece of black velour / velvet - covering the electric contact on the Fringer adapter. Suddenly, the camera did again recognize the (manual) input of the focal length - I had earlier registered in the GFX camera.
Now the image stabilization works - leading to better images and somewhat more stabilized viewfinder image when i try to focus with the manual Pentax 645 lenses.
Wonderful !
This was my earlier solution
because I already had the Fringer EF-GFX adapter, and felt that a whole new (dumb) Pentax 645 to GFX adapter was too expensive. Therefore, i bought a lower priced P645 to EF adapter instead - by merging that one with the Fringer.
As I mentioned, the electrical contacts on the Fringer EF-GFX adapter confuses the GFX camera, disabling in-body image stabilization when using Pentax 645 lenses.
Covering the contacts with velour, solved the problem. Now you can dial in a focal length manually on your GFX camera, and it will register as such accordingly.
The new Fringer (AF) P645 - GFX adapter
Fringer brand new adapter for Pentax 645 lenses, will make my double adapter obsolete. Thanks to their tech, the new adapter will enable AF (with FA and DA lenses), enable image stabilization on all Pentax 645 lenses, even dynamically with zoom lenses, and register EXIF data in the image files.
So, all type of Pentax 645 lenses will benefit from the new Fringer P645-GFX adapter. I will get back to it, once I have it in my hands and can test it more deeply.
Adding the 11 mm extension ring
to the manual 645 Pentax-A 150mm ƒ3.5 lens - shows good properties. You get a lot closer than the lens' original min focus of 1.5 meter. Due to that the lens has no floating lens elements, the quality in sharpness does not really decrease. Even at wide open aperture ƒ3.5 - you can pull out fine details after some mild sharpening.
It shows that this old film lens from the 80s, has unusual good potential combined with a beautiful image rendering, and very low price on the used market. Plus it is really small and light.
I will definitely keep using this lens actively with the Fujifilm GFX camera !
Lovely !!
What is fun with all this experimentation is, that it is lovely to see that an old lens can perform this admirably. I never dreamed that the manual version of the 645 Pentax 150mm lens would perform so nice. I am not striving for perfection. I mean, native Fujinon GF lenses made for the GFX mediumformat system are the closest to perfection - and will give the highest quality.
Perfection is however not my goal, and i welcome lenses with character. Preferably still with a good level of optical quality. I think the 645 Pentax-A 150/3.5 lens fits that bill, together with a lovely image rendering style, that pleases the eye and feeling.
Yeah, I know... i babble a lot
my Diary and what I write about in photography, are often "in progress". I don't provide any final or ready, slick solutions. I just write "to myself", along the road of the small things I discover. Since I don't have photo friend - things take time for me to discover.
That's it.
Not more, no less. |
