Just look FA 50 1.4 (220gm) to the DA*55 1.4 (375 gm) and DFA 50 1.4 (910 gm)
On the other hand telephotos are going the other way. My Tamorn 300 2.8 is six pounds (and was resaonably popular in Nikon mount in 2002)
The AF-S NIKKOR 500mm f/5.6E PF ED VR is a fraction of the size of most full-frame 500mm lenses, freeing you to be as nimble as your subjects.

3.2 pounds. Half the size, of my Tamron.
Quote: Lighter, more compact optics don’t just benefit your mobility—a lighter focus lens group allows the autofocus system to focus faster, too. With the AF-S NIKKOR 500mm f/5.6E PF ED VR, Nikon’s Silent Wave Motor (SWM) is able to operate at peak performance for fast, quiet autofocus
.
Imagine a 500mm ƒ5.6 PLM. I know anyone who has used the 55-300 PLM is already drooling.

Originally posted by DW58 Just to be clear my comment was not directed at anyone in particular. And luckily our livestock have dwindled down to only four goats now so the hay hauling is not the chore it once was when we had 70 and 15 head of cattle. I just try to keep things in perspective. The reality is that camera lenses are just not heavy. Period.
They can be heavy enough to suck the joy out of photography however.
I never had to balance a bail of hay on top of a tripod.
