Both K-1 Mark II and K-3 Mark III were used to take the samples, but the posted pictures are just too small to tell about the resolution. The colour and 3d rendition as well as bokeh of the lens look nice this time. This lens seems very suitable to be used on both Full Frame and APS-C bodies.

The test pictures were taken with a full-frame K-1 II, all posted sample photos are downsized to 10.7 mega-pixels. IMO, the image centre resolution looks good even when the lens is wide or near opened and that corner-to-corner sharpness is achievable when it is stopped down. However, I am not impressed with the dynamic range of the samples (which looks really bad) and neither the colour rendition of those. Let's see more samples to verify and judge in due course.
The Chinese Taobao website has already had the Chinese made LA-KE1 adapter put on sale (click here for one of the product links).
B&H also accepts pre-orders for this product and I think it will be available in the US very soon.
However, it can be seen in the comment section of the above Taobao product link from the users who have already purchased the adapter about the various issues such as its power hungriness and overheating, not supporting quite some Pentax AF lenses including the film FA50/1.4 and the digital DA17-70 and DA*200, as well as some noticeable delay in AF with the FA Limited lenses (and the AF is not quite smooth, too) and etc.
I hope this adapter will be improved later for better performance and compatibility, by means of firmware update and/or hardware revision. Not until that I shall consider to buy one for playing and use of my existing Pentax glass with my Sony FF mirrorless body.
Found this interesting article (in Traditional Chinese, Google English translated page here) that's worth a read.

Side-by-side comparison tests were done with the MZ-S for film and the Fujifilm GFX50S digital cropped medium format body. To view the test pictures in their original size (which can be enlarged), just right click and select to view the pictures in a separate/new tab in browser.
Besides the comments made by the author of the article, you may find other differences by yourself. As for years, I blog, you decide. :-)
