a very good converter

Since I can only associate myself with the previous speakers positive. My expectations were not disappointed.
Even in low light, good results can be achieved.
Tripod and remote shutter prove to be indispensable helpers.
The very first attempts are in the above sequence (No. 13 -. 15) set:
- The cormorant
- The then following image with horizontal tiles and the green leaves in front of it
(About 10m away; is taken in hazy fog in the morning)
- I've also tried it freehand (bird in flight).

Tripod and remote shutter release but I would prefer over freehand.
From me there is a smooth buy recommendation.
