Originally posted by jumbleview For people who already have e-mount camera and K-lenses, sure. As far as I myself does not have Sony camera I would probably better to invest into the future Pentax K-3iii.
I shoot with my K1 for my AF lenses.
But I use an A7 for my manual Pentax lenses.
I certainly would wish Pentax makes a MILC for my Pentax lenses since I prefer the features, ergonomics, color and thoughtful design that goes into a Pentax.
However, looks like I have no choice but to fork out the cash for A7iii and this AF adapter when its out.
The capability to use AF lenses as well as manual ones on one camera is a significant enough for me to buy a A7iii.
Concerns on the AF adapter will be reliability and AF speed.
I would expect quite a demand for it so probably no choice but to grab one when its out and find out for myself.
