sort of; of all my gear, i only have 2 DX lenses. These are the 18-50 f2.8 and the 18-125. all of my bodies are dx bodies. thus the 18-50 is really the dx version of my 28-75. so if i go to film or FF i am still set. remember to always think about the FOV of your lenses when on a dx camera.

to comeback at your question so a 28-80 and a 28-105 added to 2 28-200 lenses. there is a lot of duplication going on here. does the 28-105 have that much of a different look to the 28-80?

yes it does , first of all the 28-80 is silver and the 28-105 is a black lens .. and about the duplication between the tamron 28-200 and the sigma 28-200 is maily caused by the lens creep of the sigma , .

ahh so then the 28-105 and sigma 28-200 would be 2 i sell of, if i were in your shoes. if you like a lens, keep it.

is there a difference in resolution of format ?

for me no, they all are DX cameras. the S3 and S5 are the famed fuji SR sensor with 2 extra stops of highlight dr

yes i have a sigma 70-300 and the vr one. i have tested a lot of 70-300 lenses. the vr is tops followed by the nikon D version then the sigma APO. these are the top 3. so replacing your G version with the VR would be a step up and works with all your cameras.

that really is the issue. the 12-24 is a FF lens. so if i go film i have 12mm on dx is like 18mm. the 18-50 is 2.8 as is the 28-75. while most folks will say the dupe, one is FF and the other is DX. both lenses are f2.8, i would not sell them to replace with something other than a f2.8 lens. I am looking at getting the sigma 24-70 f2.8 to replace the 28-75. i also am looking at getting the 70-200vr, this will over lap my 120-300 f2.8 but the vr makes it a much more useful lens. my stable hands, i hand hold my bigma at 500mm

if you think about my advise: i kept the ff glass separate from your dx glass. i did this because in the next few years i am betting most of us will have moved to ff digital because the costs will have come way down.

so back to you, the 16-85vr is the dx version of the 24-120vr. so most folks will jump all over it. but here is my case for the 24-120vr. on a dx camera its fov is like a 36-180mm with vr added it makes for a compelling rang. and i remember when 35mm was wide angle. a lot of landscape photogs i know shoot most of their landscapes with a 35mm lens.

so i think upgrading your 70-300 to the vr version is a good move, from there a hard think about the 24-120 vr and then for wildlife the 80-400 or one of the sigmas. and you will have vr lenses from 18-400. the huge over lap of the 70-300 and the 80-400 is the weight. once you heft the 80-400 you will understand that you will not want to use it everyday.
