On the Hunt

This is a shot I got in the few moments when the male tiger came out of hiding to check if his morning meal was around.  He looks, shall we say, quite focused on business!

 Hi Trevor! Have you had any pulsing issues with this lens? I'm looking to upgrade from my 150-600c due to pulsing focus issues. Thanks!

Trevor, 

I just saw this. The lines around his face are fantastic and would definitely disorient any potential prey.

I certainly would not him stalking me.

Sorry for the delay in responding.
I no longer have my Sigma 150-600c, however I used it a lot with all of my R-series cameras: R5, R6 and R6II with no specific issues.  Sigma went to the effort of posting a video to say their lenses work with R-series bodies, but the demo's were using the FF R6.  The issue that is most reported is to do with the R7 and is not limited to that optic.  If you want to see the whole explanation watch this:

I have my own explanation of this that concurs with Canon's explanation, but it is lengthy, however the bottom line is the issues are generally limited to the body model.  You will never get a 100% hit rate with wildlife, but below 50% was not reasonable.  I avoided the R7 for that reason.

As to the Sigma 60-600s, it's a fabulous optic, much heavier, but again I have had nor specific issues with that on my FF R-series bodies.   It's about the best optic for larger sensors (APS-C and FF) out there as regards an all-in-one lens.  If you do a search on Share my photos for Sigma 60-600 there should be some other images taken with it.

Yes, he was waiting to be fed so looking seriously at anything that might be available!
