So I got a Sigma 120-400, tried to make it work for me over the weekend but it was front focussing and was uber soft wide open. Traded it in for a Sigma 150-500.....This lens is the opposite, nice and sharp and contrasty, really like it.
Today (my second day with the lens) I'm panning some BIF's, then some stationary subjects and back and forth, switching the OS from mode 1 to mode 2, back and forth and notice the OS isn't zinging in while in mode 1 (for staitionary) So it now works in mode 2 and not mode 1....Took out the battery, unmounted the lens, cleaned the contacts and so on and so forth, still doesn't work.
The thing is.....I can still return it to B&H and exchange it for another one, will take a week or so for them do the turnaround/exchange...or I can send it to Sigma and have them fix the OS.....But the optics on this particular lens are superb, from what I'm seeing, a little better than most. Worried if exchange it with B&H I'll get one that isn't this sharp....
What would you do? Besides exchange it for a 100-400L...LOL
. Unfortunately, I need some other stuff first.
