My original post is over on micro43.org.
Picked up my new-to-me Canon 55-250 STM this afternoon. Shot the mergansers on the way home, then this evening I saw the fox in the field next to my house. The fox was cropped by about 60% and the mergansers by 70%.
I shot aperture-priority and used S-AF. There’s a slight amount of motion blur with the foremost merganser. AF speed was fairly reasonable IMO; however, I am a longtime Pentax shooter and I think most of us know about Pentax’s history of slow AF, so surely that influences my perception.
I’ll continue documenting my experience with the 55-250 in this thread.
