Thank I appreciate your comments I'm now thinking that anything l l less than 400 (including the 140 plus x2) would be a compromise for my intended use. As you say the weight issue is relative.

Thanks for reply but a max of 230mm isn't that much over my 55-200 I think I need to be at least 300mm for what my intended use, so the 100-400 or the 55-140 plus 2x tc seems the way to go. Both are heavyish lenses but as I'm generally happy with my 55-200 I'm favouring the longer reach of the 400

Thanks for the reply and suggestion of renting. I guess another optiom for me is to keep my 55-200 for more general day to day use and get the hefy 100-400 and limit its use to field trips, though I do like the 55-140 performance, hmmm

thanks for the reply. sorry i should have said my intended use will mostly be wildlife, birds in flight (hopefully) though possinly some outdoor sport too. The shots are just for personal use possible printing but nothing too large

Anyone?

I'm expecting my new X-T4 to be delivered tomorrow, an upgrade for my X-T20 and am also taking the opportunity to review my lenses. I'm getting the 16-55 to replace my 18-55 and am planning on adding the 80mm macro too. I already have the 55-200 telephoto zoom but want to extend the range though I'm worried that the 100-400 telephoto is just going to be too big for the camera. I don't think either the 1.4 or 2x converters work with my existing telephoto lens so was considering investing the the 50-140 with a 2 x converter as a compromise but am worried about that combination impacting on the premium performance from the 50-140. Is the 100-400 really just too big for the size of the camera? If I go with the 100 -400 I wouldn't have coverage from 55 -100 but would have the 80mm macro to bridge the range. Are there any converters that will work with my 80-200? What can I expect from the 50-140 paired with the 2x converter? How would results compare with the 55-200? All opinions welcomed
