I thought between 135mm 2.0 DC and this lens . I took this one. I was afraid that it was heavy, I would quickly get tired, etc. - but no, I quickly got used to it. The stub just compensates for the easy walking of the hands from the weight (and from the wind if you shoot in the mountains). Now I don’t notice the weight of the lens, everything is fine. But what it made sense to be afraid of was a 60% useless lens hood (I compare it with a 70-300mm tamron). Otherwise, a great lens. 4 stars in the rating - in terms of an ideal lens))
