A fox den was established in the woods next to me in the spring. Last time I had the 150 – 600 mm Sigma Sport lens I never got a good chance to shoot the male rooting around in our compost pile. Two weeks ago the parents and now large kits stopped showing up around the area and I assumed I’d lost my chance. I rented the 150 – 600 mm Sigma Contemporary for my vacation this week to compare it to the Sport. Today the male fox was spotted a couple of times. So I set up near the compost pile at 6:30 pm and sure enough he showed up. The lens behaved well and I took a bunch of shots. But stupidly I didn’t even notice I was shooting at 150 mm! I was shooting macro all day with the Sony 90 mm macro and I was completely used to shooting everything in the magnified setting so doing it now felt natural. Well, the crops are okay, but that’s got to be the most bone-headed and frustrating mistake I’ve made in at least an hour. But I’m sure to do something stupider soon enough and then I’ll feel better about this one.
