Can someone verify how soft lock and zoom lock works? I believe my lens may not be working properly - I can only engage the lock at the marked focal lengths (150, 200, etc.) and I can't "feel" any soft lock which I assume should occur at those marked focal lengths. Should I be able to lock zoom at any focal length?

TIA

The hard lock is only at the 150mm length. When locked you cannot manually zoom the lens. The soft locks are at all other marked focal lengths including 600mm and will prevent lens creep when engaged, but you can manually zoom the lens without unlocking. Just went down and checked mine to be sure.

The soft locks only work at the marked focal lengths, so your lens is working as designed. You have to use the lock button at those focal lengths - the lens doesn't automatically lock, so you won't "feel" any lock.

The softlocks as mentioned are at all main focal lengths - you can flick in on at 400mm (for example) but if you wish to zoom - it will snap out of that softlock position with a little excursion. Its a great feature.

Thanks for the feedback, the following from the Sigma website had me wondering

"The Sigma 150-600 Contemporary also touts a new zoom lock switch that can be locked at any focal length"

Perhaps an unfortunate Japanese to English translation. Locked at any focal length yes, but easily zoomed with a touch of force.

I never use zoom lock and have found no to very little creep. Generally stays where last used unless out towards the very long end of the range. Setting the lock would be more time and trouble than needed. This is when used with the lens hanging from a shoulder sling and doing a fair bit of walking around in terrain that can be unfriendly. I expected a lot of creep so have been very umpressed that it is still so good after owning the lens since it came out.

But i guess this all comes down to how you use it.

I use the soft lock all the time and it doesn't take any time to use. In fact, it is one of the nice upgrades from the 150-500. I prefer not to keep the lens fully extended while walking with the camera/lens hanging from my shoulder, so I use the soft lock at 300 and all it take is a quick zoom to 600 when I need it. Since it is a soft lock, I don't have to disengage the lock, just twist the zoom ring.
