Choice of Lenses
Can't make up my mind to buy a Tamron 18-400 or a Sigma 100-400 Lens. It will be used on a Nikon D7200. Have trawled the net and read many
reviews about both lenses; but none are positive one way or the other. Anyone on this forum has/had one of these lenses; if so what was your
findings. Thanks for any help on this quandary.
