Speksit ja lupaukset vaikuttavat hyviltä:

The KA-KE1 Magic Ring Pentax K Lens to Sony E-Mount Camera Adapter from Monster Adapter allows select KA-KE1-mount autofocus DSLR lenses to be used on Sony E-Mount camera bodies, while retaining electronic communication and autofocus function. This adapter has a built-in AF switch, screw-drive focus motor, aperture motor, and communication and power supply contacts. It can support KAF, KAF2, KAF3, and KAF4 lenses from 1986 to the present and can automatically identify traditional screw-drive focus lenses, SDM/DC lenses with built-in motors, lenses with traditional lever-type aperture, and electromagnetic aperture lenses.

Available firmware for the adapter updates can be installed through the camera body.

Minulla on vielä useita mainioita Pentaxin AF objektiiveja, ja tälläinen adapteri olisi mainio Sonyn peilittömän kanssa. Täytyy laittaa harkintaan kunhan ensimmäiset kunnon käyttäjäkokemukset ilmaantuvat luettavaksi...

Samalta firmalta tulossa vuoden lopussa myös Nikon F-Sony E AF adapteri:

MonsterAdapter LA-FE1(Nikon F to Sony E adapter) . MonsterAdapter LA-FE1(Nikon F to Sony E adapter) won the gold medal in the Japanese DGP2022 lens accessories category today! Thank you all! Here we will demonstrate the v03 firmware with G Driver applied. The v03 firmware is currently under development and is scheduled to be available by the end of this year after the release of LA-EA4r v06.
Vai onko jo ilmestynyt?
Vastaus: On näköjään...

Nyt porukka on jo saanut adapteria.

Adapterista tullut ristiriitaisia kokemuksia. Osalla toiminut ok, osalla ollut joitakin ongelmia tiettyjen objektiivien kanssa.

Monsteradapter päivittää jatkuvasti firmware. ver. 2 on kohta tulossa.

Heidän FB ryhmästään voi katsoa kokemuksia. Pentax- Sony AF adapteri kulkee siis nimellä KA-KE1 Pentax K Lens to Sony E:

Adapteri ruuviräikällä. Epic success. En uskaltais pistää himmelin perään limitedejä.

Joo, no ruuviräikkä täytyy olla jos meinaa automaattitarkentaa aika isoa osaa Pentaxin laseista...

Tälläistä yksi käyttäjä kirjoitteli adapterista:

It fulfills most of my expectations (but did not exceed them). I am using it with A7 III.

It works. AF works only on supported lens. EXIF and body controlled aperture works on many (but not all) other FA-compatible lens.

Requires Sony camera with PDAF and no advanced AF functionality seems to be available - AF-S and AF-C are there, tracking should work to some extent, but I did not test it. Since AF speeds are average, I would not expect excellent performance in AF-C, but it should be usable in simple cases.

AF/MF switch physically disengage AF screw which allows normal manual focus.

There is another switch to select screw/SDM when both are available, but I do not have any SDM lens, so I can't test that.

Adapter requires KA-compatible lens - it only supports aperture ring set to A or lens without aperture ring at all - which is a plus in my eyes, since it was not possible to properly use such lens with dumb adapters before.

EXIF is properly populated with necessary exposure info, lens model is added in the following format: "E 50mm F1.8". As of note - exiftool reports lens mount as "5" (A-mount") which is probably due to the way lens is emulated for Sony camera.

I tried the following lens:

AF works ok:

SMCP-FA 31mm f/1.8 AL Limited
SMCP-FA 35mm f/2
SMCP-DA 40mm f/2.8 Limited
SMCP-FA 43mm f/1.9 Limited
SMC DA 50mm f/1.8
SMCP-FA 77mm f/1.8 AL Limited

Meinaan et mistä tietää mitä ping pong adapterin logiikka tekee noiden ruuvilasien kannalta? Vähän liikaa vääntöä ja varsinkin jotain af-c huudatusta niin jo on rattaat kohta halki. K-1 jo vääntää niin jytkysti ratasta et noiden jeesuksen aikaisten metallivatien barrelin osat helisee.

Niin, onhan se aina mahdollista. Muistaakseni Sony laittoi johonkin A77 tai A99 malliinsa aikoinaan niin tehokkaan moottorin ruuvitarkennukselle, että jostakin Sigmoista pärähti rattaat rikki.

Voisi kuitenkin kuvitella, että adapterin sisään ei laitettaisi ihan voimakkainta mahdollista moottoria, moottorin koon ja virransäästön takia...

Uusi firmware, nyt toimii jo useampi Pentax objektiivi:

Päivitystä tähän adapteriin liittyen:

Tämä oli aika mielenkiintoinen huomio:

Bring new life to a failing SDM lens with AF type selection

On the opposite side of the barrel you'll find a smaller bulge for the aperture control motor and a nice spring-loaded mount release switch. You'll also find one more tiny switch hidden beneath the top of the K-mount inside the adapter body, but chances are that you'll never need to use it. If you do, though, it could breathe new life into an otherwise-broken optic which might well have been beyond economical repair.

Flick this switch out of its default position and for lenses which offer a choice of either in-lens or screw-drive AF, operation will be locked into the screw-drive mode. If you own a lens with a failed internal motor that's potentially a big deal, breathing new life into an otherwise AF-less lens. Given that SDM motors have a questionable reputation, especially those which aren't used frequently, this switch could be a lifesaver for some Pentaxians.
