Sigma 50-500 non-DG version?
I have a 10D and have used the 50-500 non-DG for a some surf shots. Not the best photos, but the conditions didn't give me much choice of shooting locations, etc, etc.
I haven't really had much chance to use the Bigma but I'm planning on doing a lot of surf/bird photography now that I've retired.
Am I giving up anything in preformance by not having a DG lens?
Would I be be better off ebay'ing this lens and going for a DG series?
