Pentax 645 LS 135mm F4 for MACRO with ext-rings ? Quality ?

Really sharp - even with all 3 rings, flash is mandatory. Even at bright daylight and 1/500s the background fades to black.
You should know how to set up your flash for LS trigger (hot shoe adapter, etc.).
See attachment 1:1. Shot with 645D, the flower has actual size of ~ 1cm

Will work as good as on 645D/Z,

O-EC107 is pulled over the small eye-cup / ring.

With my 645D it is always with a specific SD-Card while writing files.
My suggestion is to try another Card or clean at least the contacts and don't delete the corrupted file.

Try PK-Tether,
it works with the 645D if you don't shoot a to fast sequence.

Should work, but without AF. IS & aperture has to be set with 645Z.

I can not trust my own eye!
Used AF and pictures look like this. (crouped 1:1 & little sharpening with LR)
With Split Screen Matte it looks like yours.

Hallo,

Does it need focus correction? Have You tried manual focus?
I did not use mine very often - can't remember such issues. I will make some test shot if the rain stops for a few hours this weekend.

Have a try with PKTether. It's free but not really stable.
Pentax has a very simple software "SW123".
There exists no SW for MAC

# Ron,
I do understand... the 645 FA 35mm is sold out. Demand is still there, Why not produce a newish batch?
Actual coating and design elements are used. Wonder if the pull-back AF-clutch is still there.

Another thing that should be done: Design new sunshades for old FA's optimized for 645D & Z.

If it's the China made adapter - no chance.
These models are only for APS-C or FF.
This is how it should look like:

Have a 500mm, and a sovjet Fisheye. Heavy, not very flare resistant, but OK when stepped down.
Give me a note when You like to try/buy them. I live near to Enschede (at the other side of the border).
