Hi folks - I shoot a D500 and Z6. Favourite subjects are waterfowl (more so than BIF). Often shoot from a boat. I have a Nikon 200-500 that I enjoy but sometimes want a shorter lens when birds are close. I have the Nikon 70-200 F4 and love it for a light sharp easy to manage lens, but sometimes would like a little more reach for the Z6. The 200-500 tends to live on the D500. Admittedly I find it a bit heavy to handhold in a boat but that is not a huge issue.
Interested in the Nikon 100-400 S Lens that is on the plan for 2021, but I fear that it will be in the $2500 US range (probably more than $3000 up here in Canada) which is more than I have to spend. So I have been looking hard at the Tamron / Sigma 100-400's. They seem close in IQ with early reviews giving the nod to the Tammy for focus tracking over the Sigma. But I have read anecdotally that the Sigma has improved focus tracking with firmware updates. Although most birds I shoot are fairly static, if a loon goes on a 300 yard take-off run I would like a lens that can track the action.
Just wondering about anyone with real life experience with these lenses. I did trip over a bit of a show stopper recently when I realized that Tamron software for the Tap-in Console does not work with Mac OS Catalina. Apparently Tamron Japan is blaming Apple for constant changes and not showing any motivation to update their lens software for the console. However the Sigma dock software appears to work with OS Catalina.
That last hiccup made me think that perhaps I better go Sigma. I am a dedicated Apple user and my old Windows PC's are 9-10 years old and past being upgradeable. I also do not want to spend $400 (or more) just to buy a Windows PC just to update lens firmware. I suppose Tamron could have a change of heart and eventually update their software to be compatible with Mac but ????
I just wonder if anyone has real life experience with the Tamron / Sigma 100-400 lenses. Sorry for the long ramble.
