I am amazed! It was definitely worth the money!

The margin of aperture and sharpness is large, you can easily use a teleconverter (I use pentax 1.7x). Aperture and sharpness of course falls, but the output image remains at least significantly above average.

because used to taking pictures with single frames in a row, instead of burst shooting - a strange situation periodically comes across: when autofocus in such a series jumps spontaneously - suppose 10 single frames were taken in 5-8 seconds, the first 4 focus as it should be, then the focus frame jumped, then 5 frames the focus is the same as the first 4.

I did not buy in 2022, I ordered from Japan (new). The price bites, but the lens is definitely worth the money. And in the 300mm f/4 segment, this price is one of the lowest.

Pros

Very good sharpness. At f / 5 such that you will not increase further. Maximum f / 5.6, and even then the photos are too sharp in my opinion then. On a very cloudy day in the shade of trees, I calmly use both 4.5 and 4.0, I am more than satisfied with the results. Very good color reproduction. The pictures are juicy and natural, you don’t have to use color correction. Excellent contrast reproduction. Excellent soft background blur.

Cons

Autofocus. I often take pictures from manual focus or with a bolted autofocus teleconverter (and there focusing is due to the teleconverter itself), so I have no complaints about autofocus, but I know that it loses insignificantly in speed compared to competitors
